The September torrential floods in 2014 the Eastern Serbia were a real disaster for local residents municipalities of Kladovo, Negotin and Majdanpek. Meteorological extreme event caused hydrological which led to declaration emergency situation all three municipalities. combined method Soil Conservation Service synthetic unit triangular hydrograph (SCS-SUH) is employed compute maximal discharges...

Abstract The water issue has become a frontier of public debate globally due to awareness sustainable development. Nigeria's resources are under serious threat from inadequate catchment management that includes widespread pollution indiscriminate waste disposal. Stormwater is now recognized as valuable resource rather than nuisance, especially in large urban centers. Growing demand for exerted ...

Sand (i.e., < 2 mm) infiltration into a gravel bed is recognized to affect sediment dynamics of coarser fractions entrainment and transport rate), near-bed velocities, morphology, pose significant engineering ecological issues. Local hydraulics, dynamics, sand the matrix are related mutually each other in gravel-bed rivers. However, relatively little research has been done explore mobile under ...

the hydrograph at watershed outlet can be expressed as hydrological response of watershed to geomorphological behavior. in present study with the aid of the gis and the concept of instantaneous unit hydrograph, the watershed response was simulated. in present physical method, the iuh is derived from three parameters of time of concentration, storage coefficient and time-area curve of the basin....

The regulated hydrograph of the Kootenai River between Libby Dam and Kootenay Lake has altered the natural flow regime, resulting in a significant decrease in maximum flows (60% net reduction in median 1-day annual maximum, and 77%-84% net reductions in median monthly flows for the historic peak flow months of May and June, respectively). Other key hydrologic characteristics have also been affe...

This paper reviews the use of an input-dependent kernel in a linear convolution integral as a quasi-nonlinear approach to unify nonlinear overland flow, channel routing and catchment runoff processes. The conceptual model of a variable kernel or instantaneous unit hydrograph (IUH) is characterized by a nonlinear storage-discharge 5 relation, q=cs , where the storage exponent N is an index or de...

A mathematically correct form of the linear storage element’s routing equation is specified requiring only a slight modification of the existing HEC-HMS routine. The new formulation, unlike the current version in use, is unconditionally stable as long as the time step and the storage coefficient values are trivially specified as positive numbers.
