Runoff from agricultural fields during the nongrowing season is a significant factor leading to phosphorous loading and diminishing water quality in Lake Simcoe, Ontario. Cover crops offer potential alleviate loss by minimizing soil erosional processes uptaking excess phosphorous; however, recent research suggests that its adoption remains relatively low. More concern lies with lack of cover cr...

Soil is one of the most important natural resources in world. Determination soil degradation has been widely attempted all over world last 50 years. This study provides a perspective comparing digital elevation model (DEM) terms Revised Universal Loss Equation (RUSLE) model, which calculates loss Mountain Karada? - Akçay Basin. RUSLE comprises topographic (LS), climatic (R), vegetation (C), (K)...

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...

It is necessary to harmonize the needs of society in terms agricultural production and land protection from various forms degradation throughout sustainable management. Assessing justification investment management resources an important step this process. Consequently, analysis soil erosion risk was carried out suburban area morphological unit Barička river watershed, using Revised Universal S...

Abstract Soil erosion is a major environmental problem that affects people's livelihoods and health, particularly in developing countries. The present study aimed to identify soil hotspot areas prioritization the Anger River sub-basin for conservation planning. Revised Universal Loss Equation (RUSLE) model geospatial technologies were adopted of sub-watershed Key parameters such as rainfall dat...

Erosion-induced soil organic carbon (SOC) loss substantially affects the redistribution of global carbon. The Chinese Loess Plateau, most severely eroded region on Earth, has experienced notable erosion mitigation over last few decades, making it a hotspot for studies. However, overall rate SOC and spatiotemporal evolution under changing environments remain unclear. In this study, we investigat...

Estimation of seepage is essential prior to lining of earth canals. In Iran such investigation has been achieved in some irrigation networks using empirical relationships derived in other countries. Estimation of water loss in canal is required in design, operation and management of water distribution systems. Water seepage may be determind by using empirical equations proposed by F.A.O. These ...

Soil erosion risk is one of the most severe environmental problems that can affect water availability, agricultural productivity and consequently countries’ sustainable development worldwide. The current study was performed in Oued El Hamma Catchment, South-Eastern Tunisia to estimate soil loss, applying Universal Loss Equation (USLE) integrated with Geographic Information System (GIS) Remote S...
