Analysis of the level regime of the Iga river of the Nizhnevartovsk district of the Khanty-Mansi autonomous district Siberia

Obtaining hydrological information in general, as well as determining the estimated water levels on water bodies, are mostly associated with the construction of hydraulic structures that allow the use of water for the needs of the national economy. The oil production industry is widely developed on the territory of the Khanty-Mansi Autonomous Okrug. Often oil and gas fields are located in sparsely populated areas where there is no information about the hydrological regime of watercourses. In order to ensure the safe operation of construction projects, there is a need to obtain hydrological information for crossed or nearby watercourses. Thus, this type of work is performed almost everywhere to solve similar problems. In this article, studies of the Iga River, located in the right bank of the Ob River, were carried out. To identify the degree of influence of the river level in different periods of the year, hydrological calculations of spring floods and rain floods were performed. Based on the calculations, a graph of the relationship between costs and levels was constructed. To determine the possible backup of the level of the Ob River to the level regime of the Iga River during periods of high waters, the levels of the Ob River were determined. Based on the analysis of joint levels, a conclusion was made about the influence of the Ob on the hydrological regime of the Iga River
