ABSTRACT: In mountain regions with lack of data from aquifer tests in wells transmissivity and permeability can be estimated by indirect (hydrometric and hydrochemical) methods. The spatial non-uniformity of near-surface zone related to morphologic position should be respected. The interpretation of base flow and slope of main river estimates mean transmissivity in valleys. However, the estimate is to be corrected with respect to the resulting estimate value and/or the catchment area. The interpretation of base flow in relation with length of hydrographic net and mean ground inc1ination indicates mean transmissivity on slopes. The estimate from hydrochemical and geomorphometric parameters of descending springs provides a relative indication of mean permeability of the near-surface zone in slopes.
