A floodplain or flood plain is an area of land adjacent to a stream or river which stretches from the banks of its channel to the base of the enclosing valley walls, and which experiences flooding during periods of high discharge. The soils usually consist of levees, silts, and sands deposited during floods. Levees are the heaviest materials and they are deposited first; silts and sands are finer materials.
The Assiniboine River is a 1,070-kilometre (660 mi) river that runs through the prairies of Western Canada in Saskatchewan and Manitoba. It is a tributary of the Red River. The Assiniboine is a typical meandering river with a single main channel embanked within a flat, shallow valley in some places and a steep valley in others. Its main tributaries are the Qu'Appelle, Souris and Whitesand Rivers. For early history and exploration see Assiniboine River fur trade.
The Red River flood of 1997 was a major flood that occurred in April and May 1997 along the Red River of the North in Minnesota, North Dakota, and Southern Manitoba. It was the most severe flood of the river since 1826. The flood reached throughout the Red River Valley, affecting the cities of Fargo and Winnipeg, but none so greatly as Grand Forks and East Grand Forks, where floodwaters reached more than 3 miles (4.8 km) inland. They inundated virtually everything in the twin communities. Total damages for the Red River region were US$3.5 billion. The flood was the result of abundant snowfall and extreme temperatures.
The Cedar River is a 338-mile-long (544 km) river in Minnesota and Iowa. It is a tributary of the Iowa River, which flows to the Mississippi River. The Cedar River takes its name from the red cedar trees growing there, and was originally called the Red Cedar River by the Meskwaki. The first Mississippi steamboat reached Cedar Rapids, Iowa in 1844, and during the next decade, the Red Cedar was an important commercial waterway. The surrounding region is known officially as the Cedar River Valley, though it is more commonly referred to simply as the Cedar Valley.
Moree is a large town in Moree Plains Shire in northern New South Wales, Australia. It is located on the banks of the Mehi River, in the centre of the rich black-soil plains.
Macleay River, an open and trained mature wave dominated, barrier estuary, is located in the Northern Tablelands and Mid North Coast districts of New South Wales, Australia.
Plynlimon is the highest point of the Cambrian Mountains in Wales, and the highest point in Mid Wales. It is a massif that dominates the countryside of northern Ceredigion.
Red Rock Pass is a low mountain pass in eastern Idaho, south of Downey in southern Bannock County. It is geologically significant as the spillway of ancient Lake Bonneville. It is located along highway US-91 at an elevation of 4,785 feet above sea level, bounded by two mountain ranges; the Portneuf to the east and the Bannock to the west.
The yellow-spotted Amazon river turtle or yellow-spotted river turtle is one of the largest South American river turtles. It can grow up to 45 cm long and weigh up to 8 kg. This species can be recognized by its black or brown oval carapace with distinctive low keels on the second and third scutes. Yellow spots on the side of its head give this species its common name. These spots are most prominent in juveniles and fade with age. Females can be up to twice the size of males.
The history of flooding in Canada includes floods caused by snowmelt runoff or freshet flooding, storm-rainfall and "flash flooding", ice jams during ice formation and spring break-up, natural dams, coastal flooding on ocean or lake coasts from storm surges, hurricanes and tsunamis. Urban flooding can be caused by stormwater runoff, riverine flooding and structural failure when engineered flood management structures, including dams and levees, prove inadequate to manage the quantities and force of flood waters. Floods can also occur when groundwater levels rise entering buildings cracks in foundation, floors and basements.(Sandink, 2010 & 7). Flooding is part of the natural environmental process. Flooding along large river systems is more frequent in spring where peak flows are often governed by runoff volume due to rainfall and snowmelt, but can take place in summer with flash floods in urban systems that respond to short-duration, heavy rainfall. Flooding due to hurricanes, or downgraded severe storms, is a concern from August to October when tropical storms can affect Eastern North America. Flood events have had a significant effect on various regions of the country. Flooding is the costliest natural disaster for Canadians. Most home insurance claims in Canada deal with water damage due to sewer back-up, not fire.
St. John's Cathedral is the Anglican cathedral in Winnipeg, Manitoba, Canada which is the cathedral church of the Diocese of Rupert's Land. It is located in North end, Luxton neighbourhood, Winnipeg on Anderson Avenue near Main Street and the Red River. St. John's Cathedral marks the birthplace of the Anglican Church in Western Canada.
Apsley River, a perennial stream of the Macleay River catchment, is located in the Northern Tablelands district of New South Wales, Australia.
The 2008 Morpeth floods occurred on Saturday 6 September 2008 in Morpeth, a town in Northumberland, northeastern England, when, following sustained heavy rainfall during the previous twenty-four hours, the River Wansbeck burst its banks and overwhelmed the town's flood defences. Nearly one thousand properties, mostly residential, were damaged.
The 2009 Red River flood along the Red River of the North in North Dakota and Minnesota in the United States and Manitoba in Canada brought record flood levels to the Fargo-Moorhead area. The flood was a result of saturated and frozen ground, Spring snowmelt exacerbated by additional rain and snow storms, and virtually flat terrain. Communities along the Red River prepared for more than a week as the U.S. National Weather Service continuously updated the predictions for the city of Fargo, North Dakota with an increasingly higher projected river crest. Originally predicted to reach a level of near 43 feet (13 m) at Fargo by March 29, the river in fact crested at 40.84 feet (12.45 m) at 12:15 a.m. March 28, and started a slow decline. The river continued to rise to the north as the crest moved downstream.
Various flooding events known as the Red River Flood have occurred in recent history. They refer to floods of the Red River of the North which forms the border between North Dakota and Minnesota and flows north, into Manitoba.
The Bonneville flood was a catastrophic flooding event in the last ice age, which involved massive amounts of water inundating parts of southern Idaho and eastern Washington along the course of the Snake River. Unlike the Missoula Floods, which also occurred during the same period in the Pacific Northwest, the Bonneville flood only happened once. The flood is believed to be the second largest in known geologic history.
The 2011 Red River flood took place along the Red River of the North in Manitoba in Canada and North Dakota and Minnesota in the United States beginning in April 2011. The flood was, in part, due to high moisture levels in the soil from the previous year, which meant that further accumulation would threaten the flood-prone region. Flood predictors in Winnipeg were worried that a dual crest of both the Assiniboine River and the Red might crest at the city at the same time. Beginning around April 8, 50 homes were evacuated and two more were flooded after an ice jam in St. Andrews, Manitoba caused the river to flood over its banks.
The Mississippi River floods in April and May 2011 were among the largest and most damaging recorded along the U.S. waterway in the past century, comparable in extent to the major floods of 1927 and 1993. In April 2011, two major storm systems deposited record levels of rainfall on the Mississippi River watershed. When that additional water combined with the springtime snowmelt, the river and many of its tributaries began to swell to record levels by the beginning of May. Areas along the Mississippi itself experiencing flooding included Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana.
