Abstract

The results of assessing the nature and degree of influence of the terrain on drained lands are presented in making a design decision on water management technology, type and design of drainage system based on the indicator of land reclamation efficiency using BIM-technologies, forecasting and optimization calculations. The schematization of the relief conditions of drained lands according to the slopes and differences of the surface of the earth is considered. Schematization was performed and the classification of the drained lands was developed according to the index of reclamation efficiency of the relief, which depends on the degree of development of the relief by the slopes and differences of the surface of the land. The generalized results of the estimation of the land reclamation efficiency of the terrain of a separate section of the drainage system, the zonal conditions of the Rivne region and the Polesie of Ukraine within their administrative limits are presented.

Methods And Techniques

Under the existing morphometric classification drained lands relief considering the size of individual forms within the specified mezorelief can be positioned as a combination of microform and Nanoform (Rychagov, 2006). Therefore, the basic linear indicators of the relief are slope of the land (i) and differences in the surface of the earth: general (∆Hgi), by a slope (∆Hi) and the local high lands or lowlands (±∆hg).

Based on the analysis, generalization and arrangement of the relief project conditions of real objects located in sufficient and unstable moisture Ukraine zones, four basic schemes of their formation by slopes and by differences in the surface of the earth are pointed out and positioned to consider (Fig. 1) (Koptyuk et al., 2011)
