Understanding flow dynamics and density currents in a river-reservoir system under upstream reservoir releases

Sensitivity Analysis of Flow and Temperature Distributions of Density Currents in a River-Reservoir System under Upstream Releases with Different Durations

A calibrated three-dimensional Environmental Fluid Dynamics Code model was applied to simulate unsteady flow patterns and temperature distributions in the Bankhead river-reservoir system in Alabama, USA. A series of sensitivity model runs were performed under daily repeated large releases (DRLRs) with different durations (2, 4 and 6 h) from Smith Dam Tailrace (SDT) when other model input variab...

Evaluating fine sediment mobilization and storage in a gravel-bed river using controlled reservoir releases

Two controlled flow events were generated by releasing water from a reservoir into the Olewiger Bach, located near Trier, Germany. This controlled release of near bank-full flows allowed an investigation of the fine sediment (<63 μm) mobilized from channel storage. Both a winter (November) and a summer (June) release event were generated, each having very different antecedent flow conditions. T...

Dynamics of a small system coupled to a reservoir : reservoir fluctuations and self-reaction

River flow forecast for reservoir management through neural networks

River ow forecasts are required to provide basic information for reservoir management in a multipurpose water system optimisation framework. An accurate prediction of ow rates in tributary streams is crucial to optimise the management of water resources considering extended time horizons. Moreover, runo3 prediction is crucial in protection from water shortage and possible ood damages. In this p...

Pseudo Steady State Gas Flow in Tight Reservoir under Dual Mechanism Flow

Gas reservoirs with low permeability (k<0.1 mD) are among the unconventional reservoirs and are commonly termed as "Tight Gas Reservoirs". In conventional gas reservoirs that have high permeability, the flow of gas is basically controlled by the reservoir permeability and it is calculated using the Darcy equation. In these reservoirs, gas flow due to gas diffusion is ignored compared to Dar...
