Wskaźnik efektywności zagospodarowania wód podziemnych jako synteza regionalnego rozpoznania Hydrogeologicznego

Abstract

Przedstawiono metody zgeneralizowanej prezentacji parametrów hydrogeologicznych decydujących o możliwości eksploatacji wód podziemnych. Część z nich wchodzi bezpośrednio do procedur obliczeniowych lub w postaci wskaźników, a część jest charakteryzowana przez koszty pozyskania i eksploatacji wód. Wynik stanowi wskaźnikefektywności zagospodarowania wód podziemnych - wielkość umożliwiająca kartograficzną syntezę rozpoznania hydrogeologicznego. THE EFFECTIVITY INDEX OF GROUNDWATER DEVELOPMENT AS A SYNTHESIS FOR THE REGIONAL HYDROGEOLOGICAL SURVEY  In the regional hydrogeological investigations, the need for the synthetic representation of the hydrogeological conditions is evident. Therefore, a new parameter has been proposed, which is characterizing in the synthetic way the elements deciding on the potential groundwater development. One of input in the analysis is the yield of the standarized groundwater well field. It combines the hydraulic parameters of the aquifer natural and induced renewability of resource the limitations to the groundwater development, in term of a permissible drawdown and the available river flow. The estimation of the yield of standarized groundwater well field can be made using the mathematical modelling. The introduction of the analytical equations simplifies the evaluation of this parameter.They modify the formula for the inflow to the multi-well water intake, assuming the balance between yield and renewability.The succesive hydrogeological parameters are characterized by the investment and operational costs. The increase of the costs is connected with the increase of the depth to the aquifer, diminishing of well yield and diminishing of the quality of the groundwater. The quality is expressed in classes or characterized by the amount of iron in water. The effectivity index of the development of the groundwater is a parameter, which characterizes all these in put data. It is the function of the yield of the typical water intake and the costs. It may be shown in the cartographic form. It should be the summary of the regional hydrogeological documentation. It can be useful in the computerizeddata banks about the groundwater resources. It may become the base of the regional systematics, which is taking into the consideration the useful character of the water. The evaluation of the effectivity index is very quick when it is done using the special computer program (IBM PC computer).
