Abstract:

Purpose. To substantiate the effective water control measures at the site of sludge collector reclamation in Yasinovaya valley in Dnipropetrovsk oblast on the basis of the established factors and conditions for the formation of hydrodynamic and hydrogeochemical groundwater regimes.

Methodology. Study of the influence of sludge collector in Yasinovaya valley on hydrogeological conditions of adjoining territory and quantification of balance components in hydrodynamic regime has been performed by simulation of seepage flow using numerical finite differences model.

Findings. According to the results of predictive calculations, the exclusion of the surface runoff entering from catchment area out of the sludge collector hydrological regime provides the necessary reduction of groundwater flood levels at the site of the sludge collector. It prevents the ground water seepage through the slurry material and tends to stabilize the hydrochemical regime of the territory adjoining to the sludge collector.

Originality. Main hydrodynamic factors that affect the level of the sludge collector influence on the formation of hydrogeochemical conditions of adjoining territory have been determined. The measures of stabilization of its overall hydrogeochemical conditions have been substantiated.

Practical value. The realization of the measures will prevent the chemical pollution of the river Dnieper and local ground waters. The research results form the basis for predicting the negative hydrodynamic and hydrogeochemical processes in the zone affected by industrial sludge collector and for substantiation of protective engineering measures as well.
