CREATION OF A DIGITAL BATHYMETRIC MODEL OF THE WATER RESERVOIR

Abstract

This article presents a comprehensive overview of the methodology used to create a digital bathymetric model (DBM) of a water reservoir. The model enables accurate estimation of key morphometric characteristics such as water volume, surface area, and depth distribution under varying water levels. The study emphasizes the application of spatial interpolation techniques, with a focus on geostatistical methods—particularly Ordinary Kriging—for generating high-precision bathymetric maps. A case study involving the Talimarjon Reservoir demonstrates the effectiveness of the approach in improving model accuracy and supporting reservoir management. The findings highlight the importance of interpolation method selection, data quality, and model validation in DBM development.
