Erosion, entrainment and deposition are complex and dominant, but yet poorly understood, mechanical processes in geophysical mass flows. Here, we propose a novel, process-based, two-phase, erosiondeposition model capable of adequately describing these complex phenomena commonly observed in landslides, avalanches, debris flows and bedload transport. The model is based on the jump in the momentum...

We investigate through computational simulations with a pore network model the formation of patterns caused by erosion-deposition mechanisms. In this model, the geometry of the pore space changes dynamically as a consequence of the coupling between the fluid flow and the movement of particles due to local drag forces. Our results for this irreversible process show that the model is able to repr...

soil erosion is a serious environmental problem in vazroud watershed, which is located in the centre of the mazandaran province, iran. unfortunately, vazroud watershed like most iran watersheds don’t have recorded data and erosion and sedimentation gages to research, monitor and model soil erosion at large watershed. in order to assess the soil erosion risk, soil erosion modeling at the watersh...

The Wind Erosion Prediction System (WEPS) is a process-based model that simulates daily weather and field conditions along with hourly wind speeds and erosion. Its physical basis should allow model application to regions outside the US for which it was originally developed. The objective of this study was to compare results from measured wind erosion with simulated soil losses as a first exampl...

In the Loess Plateau, soil erosion has not only caused serious ecological and environmental problems but has also impacted downstream areas. Therefore, a model is needed to guide the comprehensive control of soil erosion. In this study, we introduced the WEPP model to simulate soil erosion both at the slope and watershed scales. Our analyses showed that: the simulated values at the slope scale ...

After wildfires, land managers must assess the potential for increased flooding, erosion, and sedimentation, and the increased threat these effects may pose to people, structures, and valued resources. A Web-based Erosion Risk Management Tool (ERMiT) has been developed to predict surface erosion from postfire hillslopes, and to evaluate the potential effectiveness of various erosion mitigation ...

ABSTRACT. Current challenges in soil erosion research have created demand for integrated, flexible, and easily parameterized sediment transport models. Most of the existing monolithic erosion models (e.g., WEPP and WEPS) are not modular, thus modifications require considerable time, effort, and expense. In this paper, the feasibility and challenges of using the Object Modeling System (OMS) for ...

abstract ground water flow and skin is the most important phenomenon in the process streams are involved not only in the face of the whole earth, but also of the life of man on earth can. degradation of coastal erosion, lateral stability and continuity in iran and around the world each year destroys fertilized agricultural lands around the river, coastal installations, bridges, and is general h...

the modeling can provide a quantitative approach and consistency in the estimationsoil erosion and sediment yield by a wide range of conditions. in this study, the integration method of revised universal soil loss equation model, geographic information system and remote sensing techniques were used in order to identify the spatial distribution of soil erosion and sediment yield in the talar wat...
