Simulation 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...
متن کاملConjunctive surface–subsurface modeling of overland flow
In this paper, details of a conjunctive surface–subsurface numerical model for the simulation of overland flow are presented. In this model, the complete onedimensional Saint-Venant equations for the surface flow are solved by a simple, explicit, essentially non-oscillating (ENO) scheme. The two-dimensional Richards equation in the mixed form for the subsurface flow is solved using an efficient...
متن کاملSimulation of Rainfall Events and Overland Flow
We are interested in simulating overland flow on agricultural fields during rainfall events. The model considered is the shallow water system (or Saint-Venant equations) without infiltration, complemented with a friction term. In this context, we definitely have to cope with dry/wet interfaces and water inflow on dry soil. We present a simplified one-dimensional model, discretized with a well-b...
متن کاملThe Virtual Mail System
Companies conduct world-wide collaborations which often involve asynchronous work with group members in di erent time-zones. In asynchronous work, the participants can easily waste days just clarifying questions because feedback is slow. For e cient collaborations, accurate \handing-o " of work between participants is crucial. Therefore, messages exchanged between collaborators should not conta...
