By: E. Langendoen; D. Wren; R. Kuhnle

Description: National Sedimentation Laboratory, USDA-Agricultural Research Service, 598 McElroy Drive, Oxford, Mississippi 38655, USA. This study was conducted to improve prediction of the depth of erosion of sand (D50 = 0.3–0.9 mm) from immobile gravel (D50 = 36.1 mm) under steady uniform flows with bed shear stresses from 0.1 to 0.9 of that required to entrain the gravel. This situation, often encountered downstream of dams, has important impli...

By: G. Nützmann; J. Lewandowski; S. Rudnick

Description: Leibniz-Institute of Freshwater Ecology and Inland Fisheries, Dept. Ecohydrology, Müggelseedamm 310, 12587 Berlin, Germany. Lacustrine groundwater discharge (LGD) can play a major role in water and nutrient balances of lakes. Unfortunately, studies often neglect this input path due to methodological difficulties in the determination. In a previous study we described a method which allows the estimation of LGD and groundwater recharge using hydraulic head dat...

Effects of Minor Drainage Networks on Flood Hazard Evaluation : Vo...

By: A. Domeneghetti

Description: School of Civil, Chemical, Environmental and Materials Engineering, DICAM, University of Bologna, Bologna, Italy. Scientific literature reports a plethora of numerical tools of different complexity (e.g. 1D, 2D raster-based or full 2D models) for flood hazard and flood risk evaluation. The correct identification of the appropriate model still represents a key aspect in the overall flood hazard process even though the potential of these modelling instruments ...

Description: University of Montpellier – HydroSciences Montpellier UMR5569, 2 Place Eugène Bataillon, 34095 Montpellier CEDEX 5, France. Flash floods are often responsible for many deaths and involve many material damages. Regarding Mediterranean karst aquifers, the complexity of connections, between surface and groundwater, as well as weather non-stationarity patterns, increase difficulties in understanding the basins behaviour and thus warning and protecting people...

By: D. C. Yoder; D. A. N. Vieira; S. M. Dabney

Description: USDA Agricultural Research Service National Sedimentation Laboratory, Box 1157, Oxford, Mississippi 38655, USA. Ephemeral gully erosion is not included in predictions made with the Revised Universal Soil Loss Equation, version 2 (RUSLE2). A new distributed application called RUSLER (RUSLE2-Raster) predicts distributed soil loss and its output can be linked with the new Ephemeral Gully Erosion Estimator (EphGEE). These models were applied to a 6.3 ha research...
