ENVIRONMENTAL IMPACT ASSESSMENT |
|
Exploratory selection of underground water is one of the most common and important sections of ethnogeny impact on hydrosphere and subsequent elements of the environment. Modern trends in water clear of the impending permanent expansion in the medium term.
Exploratory selection of underground water inevitably damages the environment, particularly in areas of massive water intake.
Initiation of assessment of possible environmental damage must be executed by hydrogeologist, that performs exploration on a specific field. This is directly derived from the concept of "operational groundwater"-they may be assigned only to the amount of water service selection which does not lead to unacceptable (the scale and quality) damage to the environment.
Final effects on individual elements of the environment should be developed by relevant professionals; in hydrogeology, only making the "boundary" conditions, i.e. forecast quantity (in the spatial coordinates support expected water balanced and hydrodynamic changes under the influence of the work of water intake structures.
The main environmental impact while pumping works:
-changes in water balance exceeding 250 hydro networks (watercourses, water bodies, marshes)
-modified depth free surface underground water-bearing horizons
-modified stringent arrays of rocks-modified hydro thermal regime (intensity and direction of heat flow) arrays of major environmental implications of long-term exploitation water intakes can lead to the following:
-the deterioration of the environment and the degradation of aquatic and near water flora and fauna
-exceeding250 hydro networks
-deteriorating terms of wetting near surface part cut degradation and landscape set in general, deterioration of load capacity arrays of rocks as grounds for fortifications with clusters of earth
-increased dangerous geodynamic processes
-changes in the spatial configuration frosten and spring thaw timing with attendant dangerous frosting phenomena.
