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 ...

Abstract The paper considers the problem of inverse flood routing in reservoir operation strategy. aim work is to investigate possibility determining hydrograph at upstream end based on required downstream using simplified open channel flow models. To accomplish this, linear kinematic wave equation, diffusive equation and Muskingum are considered. achieve end, an solution afore mentioned equati...

It is widely accepted that spring hydrographs are an effective tool for evaluating the internal structure of karst aquifers because they depict response whole aquifer to recharge events. The hydrograph affected by various factors such as flow regime, geometry, type recharge, and hydraulic properties conduit. However, effect conduit network geometry received less attention required more comprehe...

The application of the polder system for flood control in DKI Jakarta has become a must coastal areas, especially with construction sea dikes along coast as solution to anticipate tidal flooding. One thing consider when using is how much pump capacity and reservoir are needed. To answer this quetions, hydrological analysis been carried out several method approaches, starting from determining ra...

The Sor and Gebba watershed has undergone several natural anthropogenic changes, as evidenced by the physical alterations artificial mismanagement of water resources in watershed. These situations alter underground storage aquifer contribution to streams. Thus, understanding baseflow enables us identify groundwater system potential dynamicity. main objective this research is estimate using hydr...

The Nye model of jökulhlaups is able to explain both their periodicity and even the detailed shape of the flood hydrograph. In this paper, we show how the model can be used to predict the shape of the hydrographs from the subglacial lake Grı́msvötn beneath Vatnajökull in Iceland, and we comment on three particular issues that have proved contentious in the application of the Nye model: the role ...

Two innovative tracer methods for the quantification of parasitic discharge in sewers have been proposed as routine applications within the scope of the European research project APUSS (Assessing Infiltration and Exfiltration on the Performance of Urban Sewer Systems). In order to improve the accuracy of wastewater hydrograph separation compared to conventional practice, the novel approaches ar...
