Oporność filtracyjna koryt rzecznych w świetle badań terenowych i modelowych zlewni Krzny

Abstract

FILTRATION RESISTANCE OF RIVER CHANNELS IN THE LIGHT OF FIELD AND MODEL INVESTIGATIONS OF THE KRZNA CATCHMENT Summary The paper presents a confrontation of fieldwork results, showing hydraulic resistance of the Krzna bottom deposits, with the parameters that define a resistivity of a fluvial channel and were received by taring a mathematic model of the catchment. During fieldworks the filtrometric method and the one of relative relation of underground and surface waters were applied. A possible use of fieldwork results was analyzed for a preliminary evaluation of channel resistance. necessary for a correct construction of mathematical models of hydrogeologic regions.
