Declining gauging infrastructure and fractious water politics have decreased available information about river flows globally. Remote sensing and water balance modeling are frequently cited as potential solutions, but these techniques largely rely on these same in-decline gauge data to make accurate discharge estimates. A different approach is therefore needed, and we here combine remotely sens...

Design hydrographs described by peak discharge, hydrograph volume, and hydrograph shapeare essential for engineering tasks involving storage. Such design hydrographs are inherently uncertain asare classical flood estimates focusing on peak discharge only. Various sources of uncertainty contribute tothe total uncertainty of synthetic design hydrographs for gauged and ungauged catchments. These c...

flood routing in rivers is a mathematical procedure to determine flow hydrograph at a point in a river. one of routing methods is based on solution of saint-venant equations for unsteady flows. because this method is very complex and need to more information of river, other methods with simple calculations and reasonably accurate results have been extended and give generally satisfactory result...

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 ...

since direct experimental evidence is not available, this must be verified through a modeling approach, providedadequate data be available. many statistical methods are used to study the relation between independent anddependent variables.this research was carried out at the western part of jazmurian basin tlocated in the southeast ofiran. in this paperused ten physical characteristics such as ...
