INVESTIGATION OF WATER USE IN AGRICULTURE OF THE KHOREZM REGION USING THE METHOD OF RADIATION BALANCE WITH RADIOMETRIC DATA MODIS

Abstract

The spatial visions of water use in irrigated lands of the Khorezm region, located in the lower reaches of the Amudarya River, were mapped and monitored using MODIS data. Land use were classified by using a recursive partitioning and regression tree with 250 m MODIS Normalized Difference Vegetation Index (NDVI) time series. Seasonal actual evapotranspiration was obtained by applying the Surface Energy Balance Algorithm for Land to 1 km daily MODIS data. In Khorezm, seasonal maximum values superior to 1,200 and 1,000 mm ET were estimated for rice and cotton fields, respectively.
