Water Reservoir Area and Volume Determination Using Geoinformation Technologies and Remote Sensing

Abstract

This article presents the method for calculating the area and volume of the water reservoir using Remote Sensing and Geoinformation Technologies. All calculations were performed for the Tashtepa water reservoir which recommended for construction in the Tashkent region. The territory of Tashtepa water reservoir was explored using the Google Earth program, was identified the alignment for the construction of dams, and the file was saved as a KML (Keyhole Markup Language) format. The alignment and the digital elevation model of the reservoir area from the online database were uploaded to the Global Mapper program which one of the geographic information system programs. Contours were formed in the digital elevation model, there was defined the longitudinal profile of the alignment along dams, surface and volume of the water reservoir were obtained for each circuit and based on the results were obtained curve lines between contour and area F=f(H), contour and volume W=f(H).
