The Gunt ( Russian Гунт ) is a right tributary of the Panj in the region Gorno-Badakhshan in Tajikistan . The mean elevation of the catchment area is 4261 m. The highest mountain is the Karl Marx peak at 6723 m .

River course

The Gunt rises on the northern flank of the southern Alitschurkette in the eastern part of the Pamir . Its water flows westward for practically the entire stretch of the river. Until it flows into the natural reservoir Jaschilkul , its course of the river meanders on the flat high plateau between the northern and southern Alitschurkette. There he bears the name Alitschur. After flowing through the Jashilkul, the river changes its flow behavior and bears the name Gunt up to the mouth. It leaves the high plateau when it emerges from the Jaschilkul and flows through an increasingly cut valley. In the further course of the river, steep, turbulent sections of the river alternate with flat sections, in which the Gunt branches out widely. The water morphology of the Gunt is still largely undeveloped.

The M41, the so-called Pamir Highway , leads from the Koj-Tezek Pass ( 4271  m ) down through the Toguzbulok river valley to the Gunt. From here the trunk road runs along the Gunt to its mouth. Shortly before Chorugh , the Gunt still absorbs the water of the Shachdara River at an altitude of 2069  m and flows into the Pandsch after flowing through the city. The border with Afghanistan is on the other, western bank of the Pandsch, opposite the confluence of the Gunt . The Gunt has a length of 296 km and drains an area of ​​13,700 km².

Hydrology

The flow regime of the Gunt is nival to glacial, with a pronounced flow maximum in the summer months and low water in the winter months. Precipitation falls almost exclusively as snow in the winter months. In 2011 the glacier area in the catchment area was approx. 607 km² (4.5%). As a result of climate change, a pronounced glacier retreat is taking place. Since 1998, an average of 7.4 km² (1.1%) of the glacier area has been lost each year. This corresponds to 96 km² of glacier area in the years 1998 to 2011. It is assumed that 10% of the annual runoff comes from the permanent loss of glacier ice. The runoff trend is therefore positive. 

Hydropower plants

The Pamir 1 hydropower plant ( ) 10 km northeast of Chorugh is the most important power plant in the region with an output of 28 MW. The water is taken 3.5 km upstream at a weir from the river and fed underground to the power plant. There is a sedimentation basin next to the weir. In the early 2000s, a drainage control structure was built on Jaschilkul. This holds back water in the lake in the summer months with high levels of drainage, which then increases the Gunt's drainage by up to 10 m³ / s in the winter months with little drainage. This enabled better utilization of the downstream hydropower plant and, together with its modernization, led to an increase in its annual output of 40 percent.

Another hydropower plant with a capacity of 8 MW is located at Chorugh opposite the confluence of the Shachdara.
