Optimal Allocation of Water for Irrigation and Hydropower
This study examines how hypothetical changes in irrigation practices affect downstream hydropower sites. Dynamic programming and simulation techniques are coupled to determine optimal...

Optimal Real-Time Pump and Irrigation Scheduling for Center-Pivot Sprinkler Systems
A comprehensive scheduling algorithm is presented for optimally integrating irrigation and pump operational decisions in center-pivot sprinkler systems. Dynamic programming successive...

Hydrologic and Institutional Water Availability
A simulation study was performed to evaluate the amount of water which can be supplied by a system of 12 reservoirs located in the Brazos River Basin. The generalized computer models HEC-3...

Meeting Environmental Commitments at Power Plants Using Real-Time Reservoir Scheduling
This paper describes two different real-time modeling systems that determine if scheduled hydro releases will affect meeting environmental commitments. The modeling system for John Sevier...

The Los Vaqueros Model: A Microcomputer-Based Reservoir Planning System
This paper describes the development and application of a set of microcomputer models for the evaluation of a complex water resources project. The Los Vaqueros Model includes components...

The State of Art of Physical Modelling of Sediment Transport
The paper attempts formula some ideas about the state of the art in the field of physical modelling of sediment transport processes. Up to now the physics of sediment transport are not...

New Developments in Modeling 3-D Sedimentation Phenomena
This paper is intended to summarize the new findings accomplished recently in an effort to develop highly stable and efficient numerical models to correctly and accurately simulate three-dimensional...

Quasi-3D and Fully 3-D Modelling of Suspended Sediment Transport
The influence of different velocity and eddy viscosity fields on the computation of suspended sediment concentration and sediment transport rates, is presented here. Two different mathematical...

Advances in Computational Mobile-Bed Hydraulics
A new conceptual approach to one-dimensional mobile-bed simulation is briefly described, along with two demonstrative examples. The approach is based on fully coupled solution of the unsteady...

Potential Flow Over a Wavy Bed: A Persistent Error
The standard small-amplitude theory of potential flow over a wavy bed is briefly discussed, together with the three special values of the Froude Number which define four different flow...

Application of 2-D Model to Reduce Sedimentation Problems
The Corps of Engineers opened Lock and Dam No. 1 on the Red River Waterway in 1984. During the first runoff season, excessive quantities of fine sediment deposited in both the upstream...

Modeling of Contaminant Transport in Rivers with Emphasis on the Interaction with Movable Boundaries
The transport of dissolved and absorbed pollutants is simulated by a one-dimensional convection-diffusion model which particularly accounts for the exchange processes at the river bed...

Friction Slope Computation for Mathematical Models
The behavior of the energy flow gradient as function of depth and velocity is analyzed for three flow resistance methods. In the paper, the necessary modifications introduced to the methods...

Comparison of n Values in Natural and Dredged Channels
Manning's n values were determined for three stream channels in two complex watersheds in North Mississippi. The study covered a wide range of channel conditions and flow...

Self-Accelerated Turbidity Current Prediction Based Upon Dynamic Turbulence Models
The structure of a self-accelerated turbidity current appears to be significantly better predicted by a dynamic Reynolds stress turbulence model than by one- and two- equation models....

Modeling Sediment Transport in Rectangular Ducts with a Two-Equation Model of Turbulence
The paper deals with the application of a two-equation model of turbulence to the calculation of flows in rectangular ducts. A non-linear relationship is used to link the Reynolds stresses...
