Regression analysis can develop unit hydrograph modeling by approaching the peak discharge (Qp) and time to (Tp) parameters. The main aim of this study is design a model based on watershed shape factors. watersheds used in are Bontojai Watershed, Jonggoa Kampili Maccini Sombala Jenelata which have slopes criteria below 10% complete recorded data Automatic Water Level Recorder (AWLR) Rainfall (A...

Although river dikes still play a key role for flood protection in the Netherlands there is a growing interest for other measures to deal with larger peak discharges, such as lowering or widening the floodplains. Regardless of the strategy chosen the assessment of its effect on the flood risk depends on the peak discharge statistics. A problem here is that the statistical analysis of peak disch...

Two outfalls, each with given tidally averaged discharge rates, are discharging into the same narrow (rapidly mixed) estuary. The lowest achievable concentration peak (in position and time) for the principal contaminant species is attained with an ‘all or nothing’ discharging policy. The discharge rate is either ‘all’ that is allowed by concentration peak or is nothing. The ‘nothing’ regime cor...

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....
