Effects of Reservoir Releases on Slope Stability and Bank Erosion
Reservoir release patterns are determined by a number of purposes, the most fundamental of which is to manage water resources for human use. Managing our water resources means not only controlling the water in reservoirs but also determining the optimum release rate taking into account factors such …

Optimization Techniques for Instream Flow Allocations
… provides an analysis technique for multipurpose reservoirs for both biological instream flow needs (IFN) and more traditional water project objectives such as water yield, flood control or economic efficiency. The constrained optimization approach used combines an implicitly stochastic modeling …

The analysis of reservoir operation rules in the southwestern United States using a hidden Markov-decision tree model
Realistic reservoir operation is an important component in basin hydrological models. However, the operation rules can be complex under various situations and are not well understood yet. The objective of the study is to find out patterns of actual reservoir operation rules in a specific region …

Effectiveness of weirs on the New River in retarding rapid releases from Claytor Lake Dam at Big Falls
Reservoir releases for power generation often cause rapidly fluctuating water levels and increased velocities in certain downstream sections of rivers. These conditions and the natural geometry of the river can render certain sections of the river dangerous for recreation. Although public utilities …

Evaluating Ecological Influences of Altered Flow Regimes Using Two- and Three-Dimensional Hydrodynamic Models
Reservoir releases for generating power need to be reconciled with efforts to maintain healthy ecosystems in regulated rivers having irregular channel topography. Fluctuating, complex flow patterns near river obstructions such as boulders and large woody debris provide unique habitat for many …

Life history and secondary production of Cheumatopsyche spp. in a small Appalachian stream with two different land uses on its watershed
… was less than from sites below food-enriched reservoir releases or from snag habitat in southeastern, coastal-plain rivers. Detritus was the greatest component of the diet of Cheumatopsyche at the two sites, but detritus and animal food had similar contribution to production downstream. The …

Numerical Solution of the One-dimensional and Cylindrical Serre Equations for Rapidly Varying Free Surface Flows
… flows that arise, for example, from; rapid reservoir releases, dam-breaks, mud slides, tidal bores, storm surges, tsunamis and flows over variable topography, are characterized by abrupt changes in the water surface. These changes produce vertical acceleration of the fluid particles. These …

Better understanding human impacts on river thermal regimes under climate change
… seasons, surface energy fluxes can only warm a reservoir’s top layer (epilimnion) while the bottom layer (hypolimnion) remains cold. As a result, the cold hypolimnetic releases greatly depress downstream river temperatures. Additionally, reservoir releases during cold seasons can increase …

Impacts of Delayed Drawdown on Water Quality and Aquatic Biota in Seasonal Wetlands of the Grassland Ecological Area, Los Banos, California
… capacity during mid-March to mid- April when reservoir releases are increased to aid salmon migration. However, this delayed drawdown may affect the quality and quantity of wetland vegetative forage, increase wetland soil salinity, and possibly alter the concentrations of algae, invertebrates, …
