Hydrological modeling of agricultural lands on the basis of GIS technologies (On the example of the Chimbay district of the Republic of Karakalpakstan)
Аннотация
The article deals with the issue of hydromodule zoning of agricultural land. The negative impact of the environmental factors of the Aral Sea requires more work on the efficient use of agricultural land in the region. The focus of the research is on the efficient use of agricultural land based on the optimal placement of Agricultural crops. Optimizing the use of agricultural land by dividing areas into taxonomic units is considered to be one of the effective methods. In this study, the land of P. Seytov’s massive, Chimboy district of the Republic of Karakalpakstan, within the Republic of Uzbekistan, was selected as a study area. Hydromodule zoning of the cultivated areas of the research object was done using GIS technologies. In this, data on soil types and mechanical composition of the object, groundwater, and irrigation methods were used. Overlay, raster calculation, and raster classification methods were used using ArcGIS 10.6 software. As a result, a hydromodule map of the research object was created. Based on the created hydromodule map, the scenario of placement of agricultural crops based on 2 different options was developed and water consumption was analyzed.
