Groundwater fluctuation of a meliorated forest catchment in connection with the climate and the growth of forest stands - 30 years of monitoring

. Additionally, the impacts on the ground water table (GWT) level, drainage, and forest health are disputed. This study deals with the behaviour of the shallow-aquifer GWT Bohemia, Czech Republic. GWT (84 m long transect wi...

Evaluation of concrete surface permeability depending on concrete formula by the methodology DOE

Durability of concrete is closely connected with the quality of its surface layer. The paper evaluates the result of three different tests of permeability (TPT, ISAT, GWT) of the nine concrete mixtures by the statistical methodology DOE (Des...
