Paracobitis ghazniensis is a species of stone loach found in Helmand basin in Ghazni River, Helmand River basin, Afghanistan. [1] [2]
The Helmand River is the longest river in Afghanistan and the primary watershed for the endorheic Sistan Basin. Part of the river is in Iran.
Lashkargāh, historically called Bost or Boost, is a city in southwestern Afghanistan and the capital of Helmand Province. It is located in Lashkargah District, where the Arghandab River merges into the Helmand River. The city has a population of 201,546 as of 2006. Lashkargah is linked by major roads with Kandahar to the east, Zaranj on the border with Iran to the west, and Farah and Herat to the north-west. It is mostly very arid and desolate. However, farming does exist around the Helmand and Arghandab rivers. Bost Airport is located on the east bank of the Helmand River, five miles north of the junction of the Helmand and Arghandab rivers.
Lake Hāmūn, or the Hamoun Oasis, is a seasonal lake and wetlands in the endorheic Sīstān Basin in the Sistan region on the Afghanistan–Iran border. In Iran, it is also known as Hāmūn-e Helmand, Hāmūn-e Hīrmand, or Daryācheh-ye Sīstān.
Arghandab is a river in Afghanistan, about 400 km (250 mi) in length. It rises in the Hazarajat country north-west of Ghazni, flows south-west passing near the city of Kandahar, and then falls into the Helmand 30 km (19 mi) below Girishk. In its lower course it is much used for irrigation, under the control of the Helmand and Arghandab Valley Authority, and the valley is cultivated and populous; yet the water is said to be somewhat brackish. It is doubtful whether the ancient Arachotus is to be identified with the Arghandab or with its chief confluent the Tarnak, which joins it on the left 50 km (31 mi) southwest of Kandahar. The Tarnak, which flows south of Kandahar, is much shorter and less copious.
Nad Ali or Nad-e Ali is a district in Helmand Province, Afghanistan. Marja is an unincorporated agricultural district in Nad Ali. The area is irrigated by the Helmand and Arghandab Valley Authority (HAVA). A small town of the same name lies 11 km to the west of the Helmand River, at the coordinates shown at the top of the page. The town of Nad-e Ali was built in 1954 as part of the HAVA irrigation project, and was settled by 3,000 predominantly Pashtun families who were given newly arable land.
The Qom River or Qom Roud receives its water from the Zagros Mountains and mounds into the Namak Lake. It is a large river in Iran. The Qom River flows through the city of Qom, and together with the Qareh Su it gains a length of approximately 400 km (250 mi). The water level strongly fluctuates between 312 m³/s and only 4 m³/s. This is partially the effect of taking water for irrigation.
Nāwa-I-Barakzāyi District is an administrative district in Helmand Province, Afghanistan located south of the provincial capital of Lashkar Gah along the Helmand River. It is bordered by the districts of Lashkar Gah, Nad Ali, Garmsir, and Rig, as well as the provinces of Nimruz and Kandahar. It falls within the area known as Pashtunistan,, an area comprising most of southeast Afghanistan and northwest Pakistan. The dominant language is Pashto and many of the 89,000 residents practice the traditional code of Pashtunwali. Nawa-I-Barakzayi's name reflects the dominant Pashtun tribe in the district, the Barakzai. Prior to the 1970s, it was called Shamalan after a small village at the south end of the district
Reg (Khanashin) District is situated in the southeastern part of Helmand Province, Afghanistan along the Helmand River on its western bank. The population is 25,600. The main village is Khanashin.
The Sistan Basin is an inland endorheic basin encompassing large parts of southwestern Afghanistan and minor parts of southeastern Iran, one of the driest regions in the world and an area subjected to prolonged droughts. Its watershed is a system of rivers flowing from the highlands of Afghanistan into freshwater lakes and marshes and then to its ultimate destination: Afghanistan's saline Godzareh depression, part of the extensive Sistan terminal basin. The Helmand River drains the basin's largest watershed, fed mainly by snowmelt from the mountains of Hindu Kush, but other rivers contribute also.
The Gowd-i zerrah, i.e., Zerrah Depression is the lowest part of an inland drainage basin covering large parts of southern Afghanistan and Iran known as the Sistan Basin. The Sistan Basin is an endorheic basin and encompasses a complex system of rivers, shallow lakes, marshes and wetlands as its watershed, draining into the Hamun Lakes in southeastern Iran. Occasional outflows from these lakes are carried back into Afghanistan by the seasonal Shile river to the basin's terminus, the Godzareh depression in Afghanistan. The depression is flat and very shallow with fine textured sediment at its lowest portions. The lowest section of the Godzareh depression is 467 m above sea level. The depression only receives runoff water when the main tributaries are overflowing every 10 years on the average.
The Helmand and Arghandab Valley Authority (HAVA) based in Lashkar Gah, Afghanistan, originally named the Helmand Valley Authority (HVA) until its expansion in 1965, was established on December 4, 1952, as an agency of the Afghan Government. The agency was modelled on the Tennessee Valley Authority in the United States, with a remit covering lands in Farah Province, Ghazni Province, Helmand Province, Herat Province, and Kandahar Province.
Paracobitis is a genus of Asian stone loaches.
The Registan–North Pakistan sandy desert ecoregion covers the dry Sistan Basin of southern Afghanistan and portions of eastern Iran and southwest Pakistan. The Registan Desert is the eastern portion of the Sistan Basin. The region is almost entirely dry sandy desert, with some irrigated cropland along the rivers. There are some seasonal wetlands at the western terminus of the Helmand River into Hamun Lake. The region support five endemic species of reptiles.
