2015/6/4
Fish fauna and macrozoobenthos were surveyed at 51 and 32 sampling sites, respectively, in mountain and submountain streams of the Vlara stream drainage area in the Bílé Karpaty Mountains. The aim of ...
Effects of drainage treatment and stand growth on changes in runoff components from a forested watershed
drainage treatment forested watershed recession limb runoff components stormflow hydrograph
2015/3/19
Runoff generation under various natural conditions has often been studied in forested watersheds for a long time. In 1967, Hewlett designed a variable source area model. The model is based on the expa...
Relationships between the parameters of aboveground parts and the parameters of root plates in Norway spruce with respect to soil drainage
Picea abies root plate waterlogged sites
2015/3/19
The aboveground parameters and the parameters of root plates in uprooted Norway spruce trees (Picea abies [L.] Karst.) were measured in the Hnile Blata locality (the High Tatras Mts.) (waterlogged sit...
Computation method of the drainage retention capacity of soil layers with a subsurface pipe drainage system
agricultural areas groundwater reservoir hydrological extremes unsteady-state groundwater conditions
2015/3/13
Methodological procedure for determining the drainage retention capacity (DRC) of surface layers under conditions of unsteady-state groundwater flow was demonstrated. DRC of the drainage system can be...
Influence of drainage system maintenance on storm runoff from a reforested, waterlogged mountain catchment
drainage treatment forest soil mountain catchment storm flow runoff waterlogging water retention
2015/3/10
The maintenance of a drainage system in a waterlogged mountain catchment impacted by earlier harvesting operations was assessed on the basis of a hydrological analysis (hydrological balance, three lin...
Estimated flows of suspended solids by the statistical analysis of outfall drainage basin of Tafna (Algeria)
catchment erosion sediment transport statistics suspension Tafna
