Ecological safety of water resources in Khujand (Tajikistan) area, in the development context of agricultural activities

Abstract

The research deals with investigation of relation between agricultural activity and ground water, surface water composition and quantity. The area of investigation is under huge increases in water consumption and active development of agricultural and economic activities. On the one hand, the agricultural complex uses groundwater and thereby reducing the level of groundwater, on the other hand, the irrigation system causes the development of a desalination zone to the depths of groundwater. Anyway, the influence into the groundwater is obvious. In the article has analyzed the relationship of surface and groundwater, hydraulically connected. It was studied the expansion of irrigation area contributes to the irrigation water flow strengthening into the rivers, also to the groundwater flow.
