Hydrogeological and environmental hydrogeological site surveys are conducted as part of geological and environmental site surveys.
Purpose:
- prospecting subsurface water sources;
- making maps and building mathematical models of the subsurface hydrosphere.
Subjects of interest:
- filtration parameters of soil;
- chemical composition of subsurface water;
- connection of subsurface to surface water;
- subsurface water dynamics;
- hydrodynamic conditions of the area.
The aspects that are subject to evaluation and forecasting are:
- hydrogeological and environmental conditions relevant to construction;
- flooding of workings during the course of construction;
- possible changes in the hydrogeological and geomechanical conditions during the course of construction and operation of projects;
- probability of filtration deformation of rock during the course of operation of projects;
- engineering and environmental protection during the course of operation of projects;
- subsurface water reserves available for water supply;
- the impact of subsurface water on the hydrological situation (ground flooding or exhaustion of aquifers);
- environmental impact of the project being designed on subsurface and surface water.
