Abstract

Groundwater and surface water interaction play an important role for groundwater recharge, drought management and water quality issues. Based on a case study in Lower Austria different techniques for estimation of riverbed infiltration were applied. The aim was to assess the impact of upstream release flow directions for the downstream sections. Due to the fact of large streambed conductivities, infiltration losses considerably contribute to the water balance of the system. The applied methods dealt with empirical infiltration formulas based on sediment particle size distribution, soil physical analysis, difference discharge measurements along river branches and point measurements of infiltration by means of double ring infiltrometer and riverbed lysimeter. Awaring the fact that the infiltration processes vary in space and time the gained results formed a basis for definition of potential values of infiltration. It could be concluded, that for the investigated environment the different methods exhibited comparable results with the exception of the empirical formulas, which tend to significantly overestimate the average values.
