Scientific and practical substantiation of geodetic and topographic works using GIS software in the design of hydraulic structures

In this article, the scientific and practical basis of geodetic and topographic work in the design of hydraulic structures and solutions intended to improve them using GIS (Geoinformation Systems) were analysed. Geodetic and topographic works are the basis for the design, construction and reconstruction of hydraulic structures in Uzbekistan. A systematic approach to the analysis of geodetic and topographic works in the design of hydraulic structures was chosen, which was used to determine the essence of the processes and laws of scientific substantiation of projects of various hydraulic structures. The geological and topographic works were carried out to monitor the condition of the Karshi main canal, and besides, several other irrigation canals in the Kashkadarya region of the Republic of Uzbekistan were studied. The main task of the Karshi main canal is to supply water to various industries, offices, institutions and irrigation canals. After taking the horizontal and vertical topographic data of the Hisorak Reservoir and processing it using the Global Mapper software, a 3D dimensional model of the Hisorak Reservoir was created.
