The APEX (Agricultural Policy-Environmental eXtender) model developed in the United States was calibrated for northwestern China's conditions. The model was then used to investigate soil erosion effects associated with alternative land uses at the ZFG (Zi-Fang-Gully) watershed in northwestern China. The results indicated that the APEX model could be calibrated reasonably well (+/-15% errors) to...

Deforestation in the Serayu watershed, Central Java province, Indonesia for agriculture and other uses leaves only 0.73% of vegetation. It has triggered a number problems such as soil loss (erosion), landslides, floods sedimentation downstream. Environmental damage control needs to be applied through appropriate conservation programs. This study aims understand distribution erosion effectivenes...

this paper presents a mapping procedure for risk mapping of water and wind erosion, whichhelps to identify protective measures needed in the planning and management of natural parks. the map of water erosion risk was developed by combining the original and revised universal soil loss equation methodologies (usle-rusle), and the map of wind erosion risk was developed using quirantes’ method. usi...

In this paper, we attempted to review the erosion in Ouergha watershed by applying two spatial approaches. The has an area of around 7300 km² representing approximately 18.2% Sebou basin which it is main tributary. order develop map using SWAT model, was important prepare a large database describing proprieties, furthermore, daily hydro-climatic data. This model integrates MUSLE equation for es...

continuous soil quality evaluation in is necessary agricultural regions to sustainable soil management and profitable agricultural production. the objectives of this study were comprised of an evaluation of soil quality utilizing integrated quality index (iqi) along with its spatial distribution in qazvin province. iqi was calculated and its spatial changes analyzed using different interpolatio...

Globally, soil erosion is a significant problem contributing to nutrient loss, water quality degradation, and sand accumulation in bodies. Currently, various climate factors are affecting the natural resources entire worldwide. Agricultural intensification, some other human impacts all contribute erosion, which issue. Management conservation efforts watershed can benefit from study. Modeling es...

Management plan model of agricultural planting information technology research and application of design system for agricultural production and digital has important theoretical and practical significance of agricultural planting. The study concluded, extracted the relevant agricultural planting design theory and technology research based on the show, applying the system analysis principle and ...

the presentstudy aimed to compare the annual soil loss prediction of rusle model with the soil erosion measurements using erosion pins and plots in khamesan representative watershed, kurdistan province. for this purpose, the distributed annual soil loss was estimated by rusle model. the suspended sediment samples were then collected daily for one year (2015/7 to 2016/6) in hydrometry station at...
