“…To evaluate the effects of different practices on soil erosion and to select the best ecological practices, simulation models can also be used. In this study, a WEPP model [FLANAGAN, LIVINGSTON 1995] was selected to assess the effects of land consolidation measures on soil erosion. The Water Erosion Prediction Project (WEPP) is a process based, parameter distributed and continuous simulation erosion prediction model developed by United States Department of Agriculture, Agricultural Research Service (USDA ARS).…”

Soil erosion by water is an important economical issue strongly deteriorating environment and requiring remedial actions. The study was designed to evaluate antierosion effect of changes in the layout of plots from along to across slope as an effect of land consolidation. Moreover, rightness of leaving newly set out boundaries of plots without any protection (i.e. sodding) was evaluated. For this purpose simulations of use of additional anti-erosive measures were done. The Water Erosion Prediction Project (WEPP) model was used. Studies have shown that in addition to the design of transverse layout of parcels during consolidation, further antierosion measures may be necessary to reduce soil loss and sediment yield. In order to minimize soil losses outside the slope, boundaries between the newly designed fields should be sodded already in the post consolidation management. Limitation the amount of erosion over the entire slope requires use of additional protection measures in the upper part of slopes e.g. shelterbelts and antierosion crop rotations. WEPP model can be recommended for Provincial Bureaus of Surveying as a tool to support the development of assumptions for consolidation projects of lands threatened by erosion.

“…The Water Erosion Prediction Project (WEPP) Flanagan et al, 2001;Laflen et al, 1991) is a physically based model for soil erosion prediction in agricultural areas, mainly in the USA. The model simulates runoff, soil erosion, sediment transport, and agrochemicals taking place these phenomena in rill and interrill areas.…”

“…The WEPP model components are: climate, surface runoff, infiltration, percolation, evaporation, transpiration, rill and interrill erosion, erodibility and processes, sediment transport and deposition, soil consolidation, residue and canopy effects on soil detachment and infiltration, surface sealing, rill hydraulics, plant growth, residue decomposition, snow melt, frozen soil effects on infiltration and erodibility, climate and tillage effects on soil properties, effects of soil random roughness and contour effects, including the potential overtopping of contour ridges (Deb;Shukla, 2011;Flanagan et al, 2001;Foster;Lane, 1987). Below, we made a brief description of WEPP model components described by Flanagan and Nearing (1995) and Deb and Shukla (2011).…”

Agricultural watershed modeling: a review for hydrology and soil erosion processes

et al. 2016

Models have been used by man for thousands of years to control his environment in a favorable way to better human living conditions. The use of hydrologic models has been a widely effective tool in order to support decision makers dealing with watersheds related to several economic and social activities, like public water supply, energy generation, and water availability for agriculture, among others. The purpose of this review is to briefly discuss some models on soil and water movement on landscapes (RUSLE, WEPP, GeoWEPP, LASH, DHSVM and AnnAGNPS) to provide information about them to help and serve in a proper manner in order to discuss particular problems related to hydrology and soil erosion processes. Models have been changed and evaluated significantly in recent years, highlighting the use of remote sense, GIS and automatic calibration process, allowing them capable of simulating watersheds under a given land-use and climate change effects. However, hydrology models have almost the same physical structure, which is not enough for simulating problems related to the long-term effects of different land-uses. That has been our challenge for next future: to understand entirely the hydrology cycle, having as reference the critical zone, in which the hydrological processes act together from canopy to the bottom of aquifers.Index terms: RUSLE; WEPP; GeoWEPP; LASH; DHSVM; AnnAGNPS. RESUMOModelos têm sido usados pelo homem há milhares de anos para controlar seu ambiente de uma maneira favorável para melhores condições de vida para os humanos. O uso de modelos hidrológicos tem sido uma ferramenta muito eficaz para apoiar os decisores que lidam com as bacias hidrográficas para subsidiar diversas atividades econômicas e sociais, como o abastecimento público de água, geração de energia, e a disponibilidade de água para a agricultura, entre outros. Objetivou-se, nesta revisão, discutir brevemente alguns modelos muito aplicados ao estudo do movimento da água e solos em paisagens (RUSLE, WEPP, GeoWEPP, LASH, DHSVM and AnnAGNPS), para fornecer informações sobre os mesmos, para auxiliar no entendimento adequado de problemas específicos relacionados com os processos de hidrologia e erosão do solo. Modelos têm sido alterados e avaliados de forma significativa nos últimos anos, com destaque para o uso de sensoriamento remoto, GIS e processo de calibração automática, permitindo aos mesmos que sejam capazes de simular bacias hidrográficas nas suas condições atuais de uso do solo e mudanças climáticas. No entanto, os modelos hidrológicos têm quase a mesma estrutura física, o que não é suficiente para simular problemas relacionados com os efeitos a longo prazo de diferentes usos do solo. Esse tem sido um dos principais desafios para o futuro: compreender inteiramente o ciclo hidrológico, tendo como referência a zona crítica, na qual os processos hidrológicos agem em conjunto a partir do dossel até a base dos aquíferos.

“…The developed soil erosion models use either an index-based approach such as Sediment Yield Index (SYI), [2] Universal Soil Loss Equation (USLE), [3] Revised Universal Soil Loss Equation (RUSLE) [4] or a dynamic approach like the Water Erosion Prediction Project. [5] In terms of temporal resolution, soil erosion models may be either event-based models (e.g., WEPP) to predict size and timing of sediment discharges or annual-based models like USLE and RUSLE to estimate long-term values of mean annual soil loss. Soil erosion is a continuous process affecting natural resources at landscape level.…”

The present paper offers an innovative method to monitor the change in soil erosion potential by integrating terrain and vegetation indices derived from remote sensing data. Three terrain indices namely, topographic wetness index (TWI), stream power index (SPI) and slope length factor (LS), were derived from the digital elevation model. Normalized vegetation index (NDVI) was derived for the year 1988 and 2004 using remote sensing images. K-mean clustering was performed on staked indices to categorize the study area into four soil erosion potential classes. The validation of derived erosion potential map using USLE model showed a good agreement. Results indicated that there was a significant change in the erosion potential of the watershed and a gradual shifting of lower erosion potential class to next higher erosion potential class over the study period.
