Hydraulic Model to Improve Debris-Handling Capability of Waterford Unit 3 Intake Canal
A 1:30 scale model was used to test the effectiveness of various modifications to the Waterford Unit No. 3 intake canal. The objective of the study was to assist in the development of...
Calculating Runaway Pressure Surges in Small Hydro Units
Determination of the runaway speed and concomitant pressure surges requires consideration of both the turbine rotodynamics and the waterhammer equations. In this paper a simplified method...
Methods for Specification and Verification of Hydraulic Design in a Turnkey Construction Contract
The project site is at the Hannibal Locks and Dam at New Martinsville, West Virginia. The existing project, a Corps of Engineers' (Corps) facility built in the 60's...
Stream Width Adjustment to Upstream Loading
Channel width adjustments takes place either by fluvial erosion or accretion of the banks, or by their mass failure under gravity and subsequent removal of the slump debris. Simulation...
PC MODEL BRESSED for Stochastic Prediction of Reservoir Sedimentation
A stochastic flow-storage/sediment-deposition model was written in BASIC with userfriendly features. It is an augmented version of the FORTRAN program RESSED (REServoir SEDimentation)...
Sediment Routing and Stream Bed Evolution Model
A one-dimensional numerical model developed by Borah, Alonso and Prasad is discussed, improved and tested. The model named STREAM routes graded sediments and simulates aggradation, degradation...
Red River Pilot Channel Design and Development
This paper presents the design parameters for two pilot channels constructed on the Red River. The factors often associated with the development of pilot channels are identified in an...
Real Time Modeling to Meet Flow Requirements at a Fossil Steam Plant
A real time modeling system has been developed to schedule hydropower operations in order to comply with discharge permit requirements at a downstream fossil steam plant. The modeling...
Hydraulic Investigation of the Cache River Basin
To develop a comprehensive solution to the problems that exist in the basin, the Illinois State Water Survey has initiated a hydraulic study. This ongoing research includes collection...
Ackers-White Equation: Transportation by Size Fractions
The Ackers-White procedure for sediment transport has been modified to permit calculation by size fractions. The original logic has been retained, but A values for incipient motion have...
Controlled-Drainage Supplements Subirrigation in Humid Regions
A computer simulation was conducted using climate and soil conditions of the humid southern U. S. to demonstrate optional operating methods for dual controlled-subdrainage/subirrigation...
Roughness Coefficients of Large Floods
Most hydraulic calculations of flow in channels and overbank areas require an evaluation of flow resistance generally expressed as Manning's roughness coefficient, n. Literature...
Non Linear Economic Models for Crop Production
Most economic models for crop production rely on the traditional linear programming approach, in spite of the fact that the objective function is almost always non linear. This paper briefly...
Crop Production Models in Water Management
A weather generating model called WMAKER is introduced. The model generates daily climatic data based on the mean monthly values of temperature, precipitation, number of rainy days and...
Choices Between Micro and Mainframe Computers
The explosion of microcomputers (PCs) has shifted a great amount of engineering computing from mainframes to micros. It has also shifted a lot of programming from FORTRAN to BASIC. This...
The Use of Spread Sheets in Water Resources Planning
With the advent of 'spread sheets' in the microcomputer explosion, a tool is available for the first time to greatly simplify many engineering procedures. This...
Hydrologic Design Criteria for Dams with Equal Reliability
Appropriateness of design criteria which require using the same Antecedent Moisture Condition (AMC) throughout Kansas for sizing dams and emergency spillways was examined. AMC values which...
Delivery System Management Via Dynamic Programming
Management of irrigation water delivery systems may involve allocating limited water supplies over both time and space under uncertain future demands. The physical delivery systems are...
Interactive Surface Irrigation Design and Evaluation Software
This paper outlines the features and capabilities of a comprehensive personal computer software system for use by irrigation engineers in design and evaluation of continuous and surge...
Effective Precipitation in Irrigation Design and Management
Effective precipitation is important in irrigation system design and operation. Numerous methods for estimating effective precipitation have been proposed in the past, including direct...
