CREATION OF MAPS OF HYDROMODULAR ZONING OF IRRIGATED LANDS IN THE SOUTHERN REGIONS OF KARAKALPAKSTAN BASED ON GIS TECHNOLOGIES

Аннотация

The problem of global climate change is on the agenda of mankind, and not only because of the increase in the average annual temperature on the planet, but also because of changes in the entire geosystem, the rise of the world's oceans, melting of ice and permanent glaciers, increased uneven precipitation, changes in the regime river runoff and climate instability. other changes involved. The article presents the results of scientific research on the hydromodular zoning of irrigated lands in the Khorezm oasis and scientifically substantiated irrigation regimes for cotton in the main hydromodular regions of the Khorezm oasis and the study of the soil-hydrogeological conditions of the oasis, a new hydromodule. Inclusion of installed observation wells for monitoring the groundwater level and mineralization dynamics in the ArcGIS software, shaping the surface by interpolation based on the groundwater level, creating an electronic digital map on the texture of the soil, hydromodule using a panel of raster calculations based on the groundwater level and texture soil information about the formation of the zonal layer.
