GEOMETRIK NIVELIRLASH ASOSIDA “TUYAMO‘YIN” GIDROLOGIK STANSIYASINING NUQTALARI ORASIDAGI NISBIY BALANDLIK FARQLARINI ANIQLASH

This article presents the results of fourth-class leveling conducted in the area of the “Tuyamuyin” hydrological station. The measurement methodology using the AT-32 optical level and a checkered leveling staff is briefly described. The importance of the data from the Main Department of Hydrometeorological Service and the benchmark values in the process of calculating the water balance volume is emphasized. Relative elevation differences between the benchmarks of the hydrological post and the water gauge staff were measured using the level. The elevations of the main, working, and control benchmarks were calculated relative to the water surface. The zero-point elevation of the benchmark located on the bank of the Amu Darya River was clarified, and it is proposed to carry out geodetic measurements for verification purposes.
