The process of harvesting water in dry and dry areas is necessary and necessary to face drought, lack of rain and scarcity of water sources in order to resist the environmental degradation that accompanied successive drought cycles on large areas of the globe and the Middle East and Iraq part of it, and it is no secret to one of the climate oscillations, especially in the rainfall in Iraq, which made the introduction of incentives to harvest water and expand it from rainfall in these areas in order to benefit from supplementary irrigation and other uses And the development of those areas. The Shore Valley includes many valleys and seasonal sewage systems where the harvesting of water is carried out naturally and also by human intervention in the wake of severe rain storms or continued rainfall, if water flows from high areas to low-lying areas by the seasonal sewage system and valleys problem waterways invested by farmers in agriculture or water harvesting by human intervention and investment in the development of basin areas,  The basin is located in the northeast of Diyala province in The Kfary district, which is currently under the administration of Kerman, Sulaimaniyah province, in the districts of Cox and Serkal, the bulk of which is located in Cox District, where the area of the basin (174,108 km2) and the extension of the basin (from South of 7Dni point has a north-to-north point where the basin expands northward to east and west where the shape of the basin takes the form of the pear) and the highest point in which it reaches (397 m) meters above sea level, and falls In the northeast of the basin and the lowest point (150 m) above sea level in the south and southeast of the basin, while the ocean of the basin (70.5257 km), the length of the basin (27.20 km) and the width of the basin (14.22 km).
Astronomically, the basin is located in two latitudes ("20'26°34-20'40°34) north and two length lines ("20'11°45-"40'02°45) to the east and the river branching network of seasonal valleys ends in the main valley, called the Shore Valley, where it heads east and south-east to pour into the Sirwan River.
