Tugaj A. Scientific ground of the water intake chink efficiency of the water supply systems

Thesis is devoted to feasibility study and development of more reliable and modern mathematical models and methods of calculation of technological parameters of underground water intakes (wells and well point systems), working in difficult hydro-geological situations and under conditions of porous medium in well surrounding zone in the form of mechanical and chemical colmatage, and calculation of productivity resumption by different methods of chemical regeneration. More accurate general ways to solve problems of spatial pressure and gravity-type filtration are obtained which helps to determine total well consumption, areas of oozing and overhand of flow, filtration supports, stipulated by imperfection of wells, and to construct free surface flow. General mathematical models of mechanical and chemical colmatage with iron compounds are developed and implemented which are make up of filtration models with regard to filtration (porousity) coefficient changes and models of dynamics of filtration deformations by colmatage.
