Connectivity due to preferential flow controls water flow and solute transport at the hillslope scale
Understanding the major controls on water flow and solute transport at the hillslope scale remains a major topic of research despite numerous hillslope experiments at different sites around the world. For example, the influence of lateral preferential flow due to pipes or macropores in the subsurface flow is still unresolved. Experiments show the often paradoxical finding of fast entry of event...
متن کاملFormation of runoff at the hillslope scale during intense precipitation
On 60 m2 hillslope plots, at 18 mainly grassland locations in Switzerland rain was applied at rates of 50– 100 mm/h for between 3 and 6 h. The generated flows were measured, including overland flow, near surface and subsurface flow 0.5–1.3 m below the surface. At some locations less than 2% of the rain flowed down the slope either on or below the surface, whereas at some others more than 90% of...
متن کاملForest ecosystem processes at the watershed scale: incorporating hillslope hydrology
Band, L.E., Patterson, P., Nemani, R. and Running, S.W., 1993. Forest ecosystem processes at the watershed scale: incorporating hillslope hydrology. Agric. For. Meteorol., 63: 93-126. An approach to distributed modeling of watershed hydro-ecological processes over large spatial scales is described. A data and simulation system, RHESSys (Regional HydroEcological Simulation System), combines a se...
متن کاملSimulation of Rain-Water Overland-Flow
Abstract. We are interested in simulating overland flow on agricultural fields during rainfall events. In this context, we definitely have to cope with dry/wet interfaces and water inflow on dry soil. The model considered is the Shallow Water system (or Saint-Venant equations) without infiltration. Moreover, the model has to be completed with friction terms. It is numerically solved by a finite...
متن کاملNumerical Aspects in Simulating Overland Flow Events
In this paper a comparative analysis of 2D numerical models for overland flow simulations have been performed; in particular they are based on the shallow water approach according to fully dynamic, diffusive and kinematic wave modeling. The systems have been numerically solved by using the MacCormack second order central scheme. The models have been tested, validated and compared using numerica...
