Physical Hydraulic Modeling for a Small Hydroelectric Redevelopment
In the development of a small hydroelectric project, the operating head on the plant is usually limited. On these projects, the need to minimize head losses and eliminating other factors...

Simple Hydrologic Modeling
Several simple models for estimating precipitation and evapotranspiration from a limited data base are discussed. Rainfall probabilities may be calculated from mean monthly rainfall. Depth-duration-frequencies...

Assessing Irrigation Impact on Instream Flow
A hydrologic model to help river system managers determines the demand for irrigation water in a two mile wide strip of land along the river using information which is generally available...

Mathematical Modeling of River Ice Process
Computer modeling of flow and ice conditions in a river is an important element in the planning of water resources project in northern regions. River ice processes are closely related...

Modeling Intake Performance Under Frazil Ice Conditions
A water intake was modeled in a refrigerated flume in an active frazil icing environment in order to evaluate alternative modifications to the prototype structure. Tests were run until...

Hydraulics of Freeze-up
A classification scheme for freeze-up of a river is proposed based upon the response of indicated stage. A conceptual model is developed to describe the course of the indicated responses....

Reservoir System Management for Hydropower
A study was undertaken to develop a comprehensive reservoir operation simulation model of the Cumberland River Basin, located in the states of Kentucky and Tennessee. Hydropower production...

Small Scale Hydropower Design Optimization
A method is presented by which the hydraulic design of small hydropower facilities can be economically optimized and then tested for sensitivity to variations in hydrologic prediction....

Computer-Aided Preliminary Optimization Model for Low-Head Micro-Hydro Installations
It is demonstrated with applications, that the use of a computer-aided preliminary optimization model can help evaluate the overall technical and economic characteristics of low-head hydro...

Studying Water System Operation by Computer
Computer modeling can greatly improve the planning and operation of water systems at relatively low cost. Time-dependent water system models can be used to refine improvements to a water...

Sensitivity of Model Choice in Reservoir Design
The Box-Jenkins method of model construction and tests of model adequacy and fit are applied to a reservoir design problem. The sensitivity of the stochastic models used to generate synthetic...

Water Resources at the Utah Water Research Laboratory
The research staff comes from a wide spectrum of water science and engineering specialties. The authors address such diverse topics as hydraulic testing, erosion studies, and water quality...

Bureau of Reclamation Hydraulic Laboratory
The Bureau of Reclamation used hydraulic models for the first time in 1930 in the laboratory of the Colorado Agriculture Experimental Station in Fort Collins, Colorado. In 1946 the Reclamation...

Hydraulic Research--U.S. Geological Survey
Research at the Gulf Coast Hydroscience Center near Bay St. Louis, Mississippi, is being conducted in an indoor laboratory, and an outdoor laboratory. Much of the current indoor lab research...

Modeling Pool and Riffle Sequences in Alluvial Channels
A one-dimensional mathematical model has been developed to predict the hydraulic characteristics of alluvial channels under low flow conditions. For a given steady discharge, channel geometry,...

Computer Aided Design in Civil Engineering
Increased application of computer aided design and drafting encouraged the organization of the symposium from which this book was derived. The papers presented at the symposium and included...

Sedimentation Consolidation Models?Predictions and Validation
In very soft sediments, questions have arisen concerning the capability of standard computational techniques used to implement calculations. The problems mainly lie in the manner in which...

Expert Systems: C. E. Potential
Expert systems, each one a very extensive computer program or set of programs, incorporate not only the facts known about a subject area, but the rules of thumb and other guidelines and...

The Campus Computer
The new Computer Aided Engineering Laboratory (CAE) at Lehigh University, Bethlehem, Pa., was established as an adjunct�a supplement�to the faculty and is dedicated to teaching civil engineering,...

Organizational Adaptation to Small Computers
The organizational changes associated with the introduction of mini- and micro-computers into firms in the construction industry is addressed in this paper. A review of the general management...
