Surface and subsurface flows interact at different spatial temporal scales through the development of saturated areas occurring when aquifer reaches surface. While this interaction exerts a strong control in partitioning water between base flow, seepage flow overland its quantification remains challenge. Here, we propose novel modeling approach based on two equivalent hillslopes to capture vari...

Abstract Though riparian areas generally have a shallow water table and higher soil moisture compared to upslope areas, climatic seasonality may trigger repellency in tropical forests, which, if persistent, could negatively affect essential ecosystem functions related resources protection such as reduced overland-flow, sediment transport, nutrient filtration. The objective of this study was ans...

Riparian areas link streams with their terrestrial catchments and decrease water pollution by trapping sediments from upland sources before they reach streams or lakes. Livestock grazing in riparian areas is a controversial practice. If not properly managed, cattle can cause degradation to both the riparian zone and adjacent water body. Vegetative, soil microtopographical, microchannel and hydr...

Nonpoint-source pollution from agricultural activities is currently the leading cause of degradation of waterways in the United States. Applying best management practices to flood-irrigated mountain meadows may improve agricultural runoff and return flow water quality. Prior research has focused on fertilizer use for increased hay yields, while few studies have investigated the environmental im...
