Irrigation and Melioration

Abstract

The article presents modern GIS methods for determining the stability of changes in irrigated areas and the depth of the ground water level.the most correct solutions are given in modeling this process. To distinguish agricultural landscapes, the classification of agricultural acreage in the lower part of the Amu Darya river region was made using 16-day periodic rasters 2017 of 2018 and the NDIS MOD13Q1 sensor of agricultural acreage, type NDVI. The annual change in the level of underground water in relation to the state of rivers and channels is analyzed. A steady change in agricultural acreage on the right Bank of the Amu Darya river Delta can be considered when the ground water level remains unchanged at the following depths: the average annual ground water level is 200 cm and the standard limit is 90 cm . The dynamics of periodic irrigation is excluded. As a result of a reduction in water resources, maintaining the critical depth of underground water remains the main problem. Research and analysis have shown that the change in the free water surface at a critical depth is directly proportional to the change in water resources of the river. Irrigated acreage is reduced by 38 % and productivity is reduced. Otherwise,due to lack of water, 10% of the area is restored with difficulty.
