Electromagnetic wave surface velocimeters ESVs measure the Doppler shift in electromagnetic waves reflected from the water surface. They provide nonintrusive water surface velocity measurements from bridges and river banks. Comparisons with laboratory and field tests show very good agreement over a wide range of elevation and planview angles. Laboratory testing shows comparable results between ...

The occurrence of permafrost in a highly permeable catchment has a profound effect on runoff generation. The presence of permafrost effectively makes the subsoil impermeable. Therefore, overland flow can be the dominant runoff-generating process during periglacial conditions. The absence of permafrost will promote subsurface drainage and, therefore, saturation excess overland flow can become th...

Excessive soil erosion hampers the functioning of many irrigation schemes throughout sub-Saharan Africa, increasing management difficulties and operation maintenance costs. River water is often considered main source sedimentation, while overland sediment inflow overlooked. From 2016 to 2018, participatory research was conducted assess influx in two Ethiopia. Sediment simulated using revised un...

Abstract. In steep wildfire-burned terrains, intense rainfall can produce large runoff that trigger highly destructive debris flows. However, the ability to accurately characterize and forecast flow susceptibility in burned terrains using physics-based tools remains limited. Here, we augment Weather Research Forecasting Hydrological modeling system (WRF-Hydro) simulate both overland channelized...

The use of vegetative filter strips (VFS) is a longstanding best management practice for the removal of sediment and other pollutants from overland flow. Many attempts have been made to model the effectiveness of a VFS based upon soil, vegetation, and sediment properties, and also upon flow conditions, but little work has been done to investigate the reliability of the existing models when cons...
