Abstract:

The aim of this paper is to establish the dynamics of groundwater condition, to make assessment of quality and using it for sub-irrigation on irrigated land in the Kazakhstan part of the Golodnostepsky massif. The research results have shown that in the conditions of growth of surface water scarcity, using ground water for sub-irrigation inreases water availability of irrigated lands. The groundwater depth is affected by the amounts of losses in filtering in channels and irrigated lands. It has been established that efficiency of irrigation systems does not exceed 0.38 in the Makhtaaral array. Therefore, the losses amount to 62% of the total water intake. So, large losses of irrigation water for filtering lead to an intense rise of groundwater depth. For example, in 1994 the area of irrigated lands with groundwater depth up to 1 m was 105 hectares, in 2002 it was 378 hectares and in 2013 – 2,562 hectares. This indicates that the area of irrigated lands with groundwater depth has increased by 18 times since 1994. In 1994 the area of irrigated lands with groundwater depth of 1-2 m was 7,792 hectares and in 2013 – 37,348 hectares. Under these conditions, using ground water for subirrigation increases their share in the total amount of water consumption. The research results show that if ground water is shallow, their share in the total amount of water consumption reaches 74%.
