Modelling the flow regime of an arid zone floodplain river, Diamantina River, Australia
Arid zone, ephemeral rivers are characterised by discharge decreasing downstream in the lower reaches due to transmission losses. Modelling the flow regime of these rivers requires data on the spatial and temporal distribution of transmission losses in these reaches. In this study, a hydrological model is developed for a 330 km reach of the Diamantina River in southwestern Queensland, where the...
متن کاملNumerical Analysis of Granular Flows in a Silo Bed on Flow Regime Characterization
The flow characteristics of a gravity-driven dense granular flow in a granular bed with a contracted drainage orifice are studied by using discrete element method and quantitative analysis. Three values of discharging rates, ranging from fast to slow dense flows, are investigated. Time variations and derivatives of mean forces and velocities, as well as their respective correlations, are analyz...
متن کاملThe study of flood flow hydraulic for determining flood bed and river influences points (Atrak River case study)
Measures should be taken to make better use of the rivers in the study, construction and exploitation optimized to contain, mitigate risks and minimize the negative consequences and the improvement of the situation in order to meet human needs and protect the environment there. Route investigated in Khorasan Razavi province and city and river Ghochan is Atrak. Physiographic parameters using dig...
متن کاملInvestigation of climate change impacts on streamflow regime of a river Arazkooseh River Basin
In this research, impacts of climate change on the streamflow hydrological status of the Arazkooseh River are discussed. After Calibration and validation of the LARS-WG, HadCM3 was downscaled under A2 Scenario in three climatology station. Beside, calibration and validation of the SWAT model were done by observed data relative to past period of times. Streamflow values are then predicted using ...
متن کاملAnalysis of flow regime changes due to operation of large reservoirs on the Zambezi River
The Zambezi Basin, a semi-arid 1.4Mio km2 catchment area spreading across eight countries, constitutes a highly complex system. With several large dams, namely Kariba, Cahora Bassa, Kafue Gorge and Itezhi-Tezhi, the basin’s hydrology is also influenced by vast wetlands with high ecological value such as the Barotse plains, the Mana Pools or the Kafue flats. The African DAms ProjecT (ADAPT) is a...
