drainage

The Desna River is a tributary of the Dnieper with a total length of 575 km within Ukraine. 468 km of them flows through the Chernihiv region. The main pollution sources of the water bodies in the Chernihiv region are utilities. Continuous monitoring of the surface water state is relevant and necessary, as it allows to give a reliable water quality assessment, to identify the anthropogenic impact factors and to assess the technogenic loading in order to establish the level of water use and to develop a set of measures to improve the state of water and the environment in general.

According to the General Plan of the city's perspective development, it is planned to develop the territories of the irrigation fields and the adjoining dam. The article details the engineering tasks of erecting the foundation-basement construction of underground structures considering the geological and hydrogeological conditions of the low-lying area of the Odessa region. Features of occurrence and genesis of low-lying part sites have been elaborated. The paper also elucidates the methods of orientation employed and water lowering during the erection of underground structures.
