Flash flood disaster ranks top among all the natural hazards across world due to its high frequency, severity and fatality. However, flash simulation is still challenging in small medium-sized catchments with complex orography, flashy hydrological responses poor observations. Three distributed models, i.e., TOPModel, HEC CNFF, are selected simulate floods seven humid six semi-humid China, consi...

Natural river channels that are sediment supply limited due to upstream water management practices and/or flow regulation often subject in-channel bed degradation and surface restructuring during natural flood hydrographs or controlled releases from dams. The heterogeneity of sizes present in these means different size classes transported more actively parts the hydrograph. A series laboratory ...

Rainfall-Runoff and Signal Separation Problems: The process of converting rainfall into runoff is a highly nonlinear problem due to the soil-water interaction that starts when rainfall reaches the ground. Additional variables to consider are evaporation, transpiration, losses due to vegetation and land use, and the different flow processes that take place in a watershed. For instance, baseflow ...

[1] In this study we investigate an event-scale transit time distribution (TTD) for a catchment located in the Santa Catalina Mountains northeast of downtown Tucson, Arizona, USA, during a series of extreme rainfall events. Traditionally, TTD studies look at the long time response of a catchment to an input variation in tracer concentration. Few studies have determined the TTD at the scale of a...
