Abstract

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.

Highlights

A number of modern geodetic instruments in the design of hydraulic structures and GIS technologies are currently used for geodetic-topographic field surveys, the organization of the process of achieving effective results, the rapid and efficient mapping of geodetic works [1,2,3,4]

Summary

Introduction

A number of modern geodetic instruments in the design of hydraulic structures and GIS technologies are currently used for geodetic-topographic field surveys, the organization of the process of achieving effective results, the rapid and efficient mapping of geodetic works [1,2,3,4]. Many works are underway to ensure the safety of hydraulic structures and their regular monitoring around the world. On May 1, 2020, 6 picket walls of the Syrdarya Reservoir of the Republic of Uzbekistan were flooded. It is vitally important to regularly monitor, control and ensure the deformation of dams in reservoirs. The implementation of new measures and solutions for regular monitoring of the deformation of large dams can prevent and control major hazards [1, 5]
