Alluvial aquifers in mountainous regions cover typically a limited area. Their contribution to catchment storage and outflow is rarely isolated; alluvial groundwater discharge under gauging stations is generally assumed negligible; and hydrological models tend to lump alluvial storage with other units. The role of alluvial aquifers remains therefore unclear: can they contribute significantly to...

T h e surface roughness of alluvial fans in Death Valley, California, changes as the fans age. Because radar backscatter is sensitive to surface roughness, it is possible to map relative surface age using Synthetic Aperture Radar (SAR) data. We have examined surface roughness estimates in Death Valley from Shuttle Imaging Radar-C SAR data with the use of a technique that we call foreground~back...

The Iraqi Western and Southern deserts are part of the Stable Shelf (Inner Platform) that belongs to Arabian Plate. Therefore, both lack tectonic forms like folds faults; however, very rarely faults regional lineaments can be seen in deserts. Although tectonically stable, tens Neotectonic indications everywhere Among those are: Straight valleys, perpendicular valley bendings, sinkholes aligned ...

An alluvial fan is a good area to install open-loop geothermal heat pump (GHP) systems due shallower aquifers, faster groundwater flow, and fewer land subsidence risks. The natural temperature change in occurs fans the recharge of river water thermal impact system has not been studied well such areas. purpose this research understand GHP on an fan. A regional 3D model flow with transport was cr...

The Middle Fork Salmon River watershed spans high-elevation mixed-conifer forests to lowerelevation shrub-steppe. In recent decades, runoff from severely burned hillslopes has generated large debris flows in steep tributary drainages. These flows incised alluvial fans along the mainstem river, where charcoal-rich debris-flow and sheetflood deposits preserve a record of latest Pleistocene to Hol...
