Human intervention makes river channels adjust their slope and bed surface grain size as they transition to a new equilibrium state in response engineering measures. Climate change alters the controls through hydrograph changes sea level rise. We assess how channel climate compares human over this century (2000–2100), focusing on 300-km reach of Rhine River. set up schematized numerical model r...

Changes in land use the Air Dingin watershed (DAS) area Padang City, Indonesia, lead to a decrease rainwater infiltration volume ground. Some Latung sub-watershed capacity with an increase surface runoff. This research aims determine effect of land-use changes on and Purposive sampling method was used this research. The measured directly field using double-ring infiltrometer, data processed Hor...

Formulation of an automatic calibration strategy for the MIKE 11/NAM rainfall–runoff model is outlined. The calibration scheme includes optimisation of multiple objectives that measure different aspects of the hydrograph: (1) overall water balance, (2) overall shape of the hydrograph, (3) peak flows, and (4) low flows. An automatic optimisation procedure based on the shuffled complex evolution ...

Seven nested headwater catchments (8 to 161 ha) were monitored during five summer rain events to evaluate storm runoff components and the effect of catchment size on water sources. Two-component isotopic hydrograph separation showed that event-water contributions near the time of peakflow ranged from 49% to 62% in the 7 catchments during the highest intensity event. The proportion of event wate...

the estimation of instantaneous peak discharge is important for watershed management because there is ainsufficient climatic and hydrologic data in countries such as iran. researchers have been forced to link constantparameters (geomorphology) and variable parameters (hydrology) to models with minimum dependence on climaticand hydrologic data for hydrologic estimation. the present study used a ...

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...

In this paper we present the rationale and the preliminary results of a research project devoted to the appropriate and innovative use of remotely sensed data for water management in semi-arid regions. The study area is the district of Yatenga, northern Burkina Faso in the subSaharan belt of West Africa, where extreme climate conditions cause several problems: drought, floods, soil erosion. The...
