Understanding of the runoff generation processes is important in understanding the magnitude and dynamics ofgroundwater discharge. However, these processes continue to be difficult to quantify and conceptualize. In this study,two digital filter based separation modules, the Recursive filtering method (RDF) and a generalization of therecursive digital filter (GRDF) were1991–2002 in the Hableh Ro...

[1] Hydrographs are an enticing focus for hydrologic research: they are readily available hydrological data that integrate the variety of terrestrial runoff generation processes and upstream routing. Notwithstanding, new techniques to glean information from the hydrograph are lacking. After early approaches of graphically separating streamflow components, hydrograph separations in the past two ...

The influence of the overlap interactions between the bridging ligands and the metal d orbitals on the super-exchange coupling constant has been studied by ab-initio Restricted Hartree-Fock molecular orbital calculations. The interaction between the magnetic d orbitals and the HOMOs of the acetate oxygens has been investigated in homologous -acetato-bridged dicopper(II) complexes which have sig...

Design hydrographs are important for the design of hydraulic structures such as spillways and retention ponds. Due to the lack of the local data, engineers have to estimate design floods based on techniques which are able to predict runoff based on rainfall on a regional basis. In this study, Clark instantaneous unit hydrographs are used to predict design flood hydrographs for the selected catc...

Estimation of flood hydrograph is of necessities in hydrological studies such as flood mitigation projects. This estimation in un-gauged watersheds is usually taken place using geomorphological characteristics of watersheds. The objective of this research is to estimate synthetic unit hydrograph using regional flood frequency analysis and geomorphological parameters of watersheds. 1-hour and 2-...
