The Somali Flash Floods are a group of flash floods that occur annually in the country of Somalia. The floods are a result of the Gu rains, which is the monsoon like rainfall that comes every March in the region. [1] Every year, in the period shortly after the Gu rains from March to July, flash floods hit the lower Jubba and lower Shabelle regions of Somalia. These flash floods cause devastation and destruction, causing casualties and displacement. In recent years, the effects of the floods have increased compared to past floods. This is due to Somali population increase and continuing lack of preparation mechanisms, and they may be exemplified by meteorological reasons as well.

Gu rains

Somali seasons include the Xagaa from July to September, the Dayr from October to December, the Jilal from December to March, and the Gu from late March to June. [2] The Xagaa and Jilal seasons are notably dry, and can cause drought. [2] Contrastingly, the Dayr and Gu seasons have the most rainfall, with the Gu being the heavier rain season of the two. The floods that shock the southeastern part of the nation are a result of the Gu rains that fall each year. The water from the rainfall flows to the lowlands near the Jubba River valley and the Shabelle River valley in the southwestern part of the nation. In addition, any excess water that runs down from the two rivers can also contribute to the water flow. The runoff then causes massive flooding for the communities in the area of the two river valleys. As the Gu rains fall every year, the Jubba River and Shabelle River Valleys are susceptible to flooding every year because of the terrain and climate of the area.

Agricultural stimulus

In addition to flash floods, Somalia also suffers from severe droughts. The droughts that occur in the country have been labeled the "Worst Humanitarian Crisis". [3] The droughts affect the agricultural production in the nation. Agriculture and livestock cultivation are a large contributor to Somalia's GDP. [4] The main areas of agriculture are situated in the lowlands of the Jubba and Shabelle rivers. [4] So, under normal circumstances, the Gu rains are looked upon with favor, as they end a long, dry period, and bring about a lush pasture in the lowlands where the rain runs off too. This rainfall makes farming easier, bringing nutrients for crop growth, and for wildlife to subsidize on. The floods bring refreshment to the drought affected farmland, and revitalize the soil for growth. [1]

Human induced increases to destruction

The communities and government of Somalia have acted in ways that increase the destruction of the floods. In recent years, with population increases, more people are forced to live in the lower floodplain areas, and thus, are more susceptible to damage and loss of life by the flooding. [5] In addition, flood relief channels that were managed by the government are now in disarray following the start of the Somali Civil War. As the current Transitional Federal Government does not have complete control over the country, there is no body that can manage relief aid, or successfully operate the flood relief channels, which distribute flood waters away from populated areas. These flood relief channels, specifically the ones near the Jubba and Shabelle river valleys, are inoperable and not protecting their respective areas. [5] Also, the deterioration of the river banks for irrigation purposes causes the rivers to swell and flood easier. [5]

Attempts to decrease devastation

Many attempts to control the effects of the flooding have been suggested. In 2007, combined efforts of organizations such as the United Nations, the Somalia Water and Land Information Management Project, the European Union, and many others suggested a new early warning system to help detect floods earlier to allow for evacuation and cover. [5] The early warning system, which would have allowed more time for evacuation and preparedness proved to be costly, and was difficult to manage successfully in the area. In addition, humanitarian aid is often offered to those affected.

Assistance drawbacks

Due to Somalia's current political situation, assistance is often difficult to acquire out of fear of the anarchy in the nation. [6] In May 2013, the United Nations offered a position of a meteorologist who would oversee early warning programs and detections throughout the nation. [7] The position went unfilled. The fear of the political system and lack of funding often restricts any ideas for controlling the outcomes of the flooding.

Resiliency

Due to the country's economic disparity, those affected are often affected severely. In the most recent flooding of May 2013, seven children were reported dead, and more than 50,000 people were left homeless by the waters. [1] With little technology to forecast the floods, and little money to build adequate housing, or provide transportation away from affected areas, the number of people affected increases dramatically. Along with the flooding, the population of Somalia suffers from drought, food crises, [8] and diseases. Some diseases become prevalent directly from the flooding and mosquito population increases. Malaria outbreaks, and Ebola virus outbreaks are direct results of the massive flooding, which have devastating effects on the human population. [9] The communities in the flood areas are not resilient to the problems the floods bring, and this causes massive damage to both property and human life.

Historical data

The Gu rains bring annual rainfall to the southwestern part of Somalia. With the rainfall, flash floods almost always affect the floodplains in some way. However, in recent years, the damage from the floods has become much more severe, with 2006, 2011, 2012, and 2013 causing tremendous more damage than previously. [1]

Comparisons to similar natural disturbances

In comparison with the 2013 Colorado floods, the floods of Somalia occurred at similar times in recent years. The Somali floods and the Colorado floods are natural disturbances that occurred from rainfall that affected an unprepared area. However, due to economic, structural, infrastructural, technological, responsiveness and aid differences, the Somali area was more damaged in context than was the Coloradoan area. In Colorado, there were around ten people reported dead, and around 1,800 homes were destroyed. [16] The capabilities of response, evacuation, and aversion are not as strong in Somalia as they are in the United States. These differences could be a major factor in the differing damage totals.

Jubba River River in Somalia

The Jubba River or Juba River is a river in southern Somalia which flows through the autonomous region of Jubaland. It begins at the border with Ethiopia, where the Dawa and Ganale Dorya rivers meet, and flows directly south to the Somali Sea, where it empties at the Goobweyn juncture. The Jubba basin covers an area of 749,000 km2 (289,000 sq mi). The Somali regional state of Jubaland, formerly called Trans-Juba, is named after the river.

Shebelle River

The Shebelle River begins in the highlands of Ethiopia, and then flows southeast into Somalia towards Mogadishu. Near Mogadishu, it turns sharply southwest, where it follows the coast. Below Mogadishu, the river becomes seasonal. During most years, the river dries up near the mouth of the Jubba River, while in seasons of heavy rainfall, the river actually reaches the Jubba and thus the Somali Sea.

Hurricane Lili (1996) Category 3 Atlantic hurricane in 1996

Hurricane Lili was a relatively long-lived hurricane of the 1996 Atlantic hurricane season that affected countries from Central America to the United Kingdom. Lili formed on October 14 from a tropical wave, which emerged from the coast of west Africa on October 4. After the storm formed, further strengthening of Lili was gradual, first to tropical storm status on October 16 and then to hurricane status on October 17. The next day, Lili struck Cuba and moved across the central portion of the island, the first hurricane to hit the country since Hurricane Kate in 1985. After emerging into the Atlantic Ocean, the hurricane accelerated northeastward, briefly peaking as a category 3 hurricane on the Saffir-Simpson Hurricane Scale near the Bahamas. For almost an entire week, Hurricane Lili oscillated in intensity while fluctuating several times in forward speed. About two weeks passed before Lili transitioned into an extratropical storm north of the Azores on October 27, which subsequently moved across Ireland and Great Britain.

Various international and local diplomatic and humanitarian efforts in the Somali Civil War have been in effect since the conflict first began in the early 1990s. The latter include diplomatic initiatives put together by the African Union, the Arab League and the European Union, as well as humanitarian efforts led by the Office for the Coordination of Humanitarian Affairs (OCHA), UNICEF, the World Food Programme (WFP), the Puntland Maritime Police Force (PMPF) and the Somali Red Crescent Society (SRCS).

October 2008 Central America floods

The October 2008 Central America floods were caused by a series of low-pressure areas including Tropical Depression Sixteen, a short-lived tropical cyclone in the 2008 Atlantic hurricane season that made landfall in Honduras. Heavy rainfall began in early October 2008 while a tropical wave passed through the region. On October 14, Tropical Depression Sixteen formed just off the northeast coast of Honduras, and at the same time a low-pressure system was on the Pacific coast. Both systems increased rainfall across the region, although the depression dropped heavy rainfall close to its center when it moved ashore on October 15. Although Tropical Depression Sixteen quickly dissipated over land, its remnants persisted for several days. Another low-pressure area interacted with a cold front on October 21, adding to the rainfall in the region.

The 2011 China floods are a series of floods from June to September 2011 that occurred in central and southern parts of the People's Republic of China. They were caused by heavy rain that inundated portions of 12 provinces, leaving other provinces still suffering a prolonged drought, a total of over 36 million people have been affected, killing at least 355 and with direct economic losses of nearly US$6.5 billion.

Between July 2011 and mid-2012, a severe drought affected the entire East African region. Said to be "the worst in 60 years", the drought caused a severe food crisis across Somalia, Djibouti, Ethiopia and Kenya that threatened the livelihood of 9.5 million people. Many refugees from southern Somalia fled to neighboring Kenya and Ethiopia, where crowded, unsanitary conditions together with severe malnutrition led to a large number of deaths. Other countries in East Africa, including Sudan, South Sudan and parts of Uganda, were also affected by a food crisis.

Continuous and heavy rains in much of Sudan, starting in early August 2013, resulted in flood damage in at least 14 of 18 Sudanese states. Over 300,000 people are reported to have been affected, with over 25,000 homes reported destroyed. Government agencies report that nearly 50 people have been killed.

Cyclone Chapala North Indian cyclone in 2015

Extremely Severe Cyclonic Storm Chapala was a powerful tropical cyclone that caused moderate damage in Somalia and Yemen during November 2015. Chapala was the third named storm of the 2015 North Indian Ocean cyclone season. It developed as a depression on 28 October off western India, and strengthened a day later into a cyclonic storm. Chapala then rapidly intensified amid favorable conditions. On 30 October, the India Meteorological Department (IMD) estimated that Chapala attained peak three-minute sustained winds of 215 km/h (135 mph). The American-based Joint Typhoon Warning Center (JTWC) estimated sustained winds of 240 km/h (150 mph), making Chapala among the strongest cyclones on record in the Arabian Sea. After peak intensity, Chapala skirted the Yemeni island of Socotra on 1 November, becoming the first hurricane-force storm there since 1922. High winds and heavy rainfall resulted in an island-wide power outage, and severe damage was compounded by Cyclone Megh, which struck Yemen a week later.

2017 Somali drought

As of February 2017 a drought ravages Somalia that has left more than 6 million people, or half the country's population, facing food shortages with several water supplies becoming undrinkable due to the possibility of infection.

The 2018 East Africa Floods were a natural disaster in Kenya, Ethiopia, Uganda, Rwanda, Somalia, Djibouti, and Burundi affecting millions of people. They began when excessive rains began falling in March 2018 following a year of severe drought, leading to massive flooding, landslides, and the failure and overflow of several dams. Record rainfall was recorded in several areas, surpassing various records set during the 1950s and during the 1997–98 El Niño event. Nearly 500 people have lost their lives while hundreds of thousands of others have been displaced.

Cyclone Sagar Tropical cyclone which make landfall in Somalia and Somaliland

Cyclonic Storm Sagar was the strongest tropical cyclone to make landfall in Somalia and Somaliland in recorded history until Gati in 2020, and the first named cyclone of the 2018 North Indian Ocean cyclone season. Forming on May 16 east of the Guardafui Channel, Sagar intensified into a cyclonic storm on the next day, as it gradually organized. The storm turned to the west-southwest and traversed the entirety of the Gulf of Aden, making landfall over Somaliland on May 19, farther west than any other storm on record in the North Indian Ocean. Sagar weakened into a remnant low on May 20.

The 2018–20 Southern Africa drought is an ongoing period of drought taking place in Southern Africa. The drought began in late October 2018, and is negatively affecting food security in the region. As of mid-August 2019, the drought is classified as a level 2 Red-Class event by the Global Disaster Alert and Coordination System. The alert level was reduced to the Orange-1.7 by 12 December 2019, as the new wet season had started. As of September 2020, the drought is classified as a level 2 Red-Class event. The drought continued into early 2021.

2019 Iran floods 2019 flash floods across Iran

From mid-March to April 2019 widespread flash flooding affected large parts of Iran, most severely in Golestan, Fars, Khuzestan, Lorestan, and other provinces. Iran has been hit by three major waves of rain and flooding over the course of two weeks which led to flooding in at least 26 of Iran's 31 provinces and at least 70 people died nationwide as of 6 April, according to the officials. The first wave of rain began on 17 March, leading to flooding in two northern provinces, Golestan and Mazandaran with the former province receiving as much as 70 percent of its average annual rainfall in single day. Several large dams have been overflowed, particularly in Khuzestan and Golestan, therefore many villages and several cities have been evacuated. About 1,900 cities and villages across country have been damaged by severe floods as well as hundreds of millions of dollars of damage to water and agriculture infrastructure. 78 roads were blocked and the reliability of 84 bridges was questioned.

The 2020 East Africa floods were a natural disaster in Rwanda, Kenya, Somalia, Burundi, Ethiopia, Uganda, Democratic Republic of Congo, Djibouti and Tanzania, affecting at least 700,000 people. They began when excessive rains began falling in March, leading to massive flooding and landslides. They caused more than 430 deaths, notably in Kenya and Rwanda. In the fall another round of floods hit the African Sahel.

2020 Sudan floods Floods within Sudan caused by rainfall

In September 2020, profuse and continuous rainfall in Sudan caused a devastating flood across 17 out of the 18 states Sudanese states with the Blue Nile reaching water levels not seen for nearly a century. It ranks among the most severe floods recorded in the region. A state of emergency was declared, and teams have worked to prevent damage to threatened archaeological sites. The flood affected more than 3,000,000 people, destroyed more than 100,000 homes, and left more than 100 people dead.

Cyclone Gati North Indian Ocean cyclone in 2020

Very Severe Cyclonic Storm Gati was the strongest tropical cyclone on record to make landfall in Somalia, and one of few tropical cyclones to do so in the country. The seventh depression, third cyclonic storm, and second very severe cyclonic storm of the 2020 North Indian Ocean cyclone season, Gati formed from an area of low pressure in the Arabian Sea, on 21 November. The storm then explosively intensified, becoming a very severe tropical cyclone and reaching its peak intensity, the following day. Gati weakened slightly before making landfall in northeastern Somalia on 22 November. Gati was the first hurricane-force cyclone to make landfall in Somalia on record. Gati then weakened and became disorganized as it moved inland. The JTWC issued its final advisory on Gati shortly after it moved into the Gulf of Aden on 23 November.

Cyclone Eloise South-West Indian Ocean cyclone in 2021

Tropical Cyclone Eloise was the strongest tropical cyclone to impact the country of Mozambique since Cyclone Kenneth in 2019 and the second in a row of three consecutive tropical cyclones to impact Mozambique in the 2020–21 South-West Indian Ocean cyclone season. The seventh tropical depression, fifth named storm and the second tropical cyclone of the season, Eloise's origins can be traced to a disturbance over the central portion of the South-West Indian Ocean basin which developed into a tropical depression on 16 January, and strengthened into a tropical storm on 17 January, though the storm had limited strength and organization. On the next day, the storm entered a more favorable environment, and it soon intensified to a severe tropical storm on 18 January. Late on 19 January, Eloise made landfall in northern Madagascar as a moderate tropical storm, bringing with it heavy rainfall and flooding. The storm traversed Madagascar and entered the Mozambique Channel in the early hours of 21 January. After moving southwestward across the Mozambique Channel for an additional 2 days, Eloise strengthened into a Category 1-equivalent cyclone, due to low wind shear and high sea surface temperatures. Early on 23 January, Eloise peaked as a Category 2-equivalent tropical cyclone on the Saffir–Simpson scale as the center of the storm began to move ashore on Mozambique. Shortly afterward, Eloise made landfall just north of Beira, Mozambique, before rapidly weakening. Subsequently, Eloise weakened into a remnant low over land on 25 January, dissipating soon afterward.
