Subject introduced to student advanced application of theoretical knowledge about flow of subsurface water. In first part is in detail explain procedure of practical measurement of infiltration and possibilities of its evaluation via equations of theoretical approach (Green-Ampt, linearized Philip equation, three-parametric equation of Philip type). Next part is oriented on derivation and terrain estimation of saturated hydraulic conductivity. Students will be practically compared results of field and laboratory techniques. Next presentations deal with derivation of unsaturated zone characteristics (unsaturated hydraulic conductivity, retention curves). Students will practically tested laboratory experiments for retention curves estimation. This knowledge will applied for theoretical application of equation for unsteady flow in vadose zone. Next important part of subject is derivation and practical application of groundwater flow over slopping bedrock (first and second Boussinesq approximation). Input parameters to the model will be used methods from previous part from unsaturated zone. Subject will be finished with practical application of above mentioned procedures for modeling of outflow from small basins.
