Measurements of Near-Survface Current in Inlets and Bays with Synthetic Aperture Radar
Synthetic Aperture Radar, SAR, provides images of land and ocean surfaces irrespective of solar illumination, and practically under all weather conditions. Developed originally for land...
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...
Diversion Structure for Peak Flow Reduction
The flood control requirements of a planned development in the City of Orange, California were such that the peak discharges ranging from an annual flood up to 25-year return period be...
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...
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...
Crop-Water Production Functions and System Design
A Task Committee to evaluate application of crop-water production functions to irrigation system design and management was established by the ASCE Irrigation Water Requirements Committee...
Infiltration as a Dependent Variable in Modeling Furrow Irrigation
Most surface irrigation models assume that infiltration is independent of surface flow hydraulics. However, wetted perimeter has been shown to significantly affect infiltration in furrows....
An Overview of Factors Affecting Land Application of Food Processing Wastes
The food processing industry can use slow rate, rapid infiltration or overland flow systems. Slow rate systems are the most common method used for land application. The limiting design...
Modeling Branching Irrigation Canal Networks
A mathematical model of branching canal network has been developed based on solving the integrated form of Saint Venant equations which describing steady and unsteady, uniform and non-uniform...
California's Dam Safety Program?The Development of Hydrology for Dams (
California's water code provides for supervision of dams and reservoirs with regard to protection of life and property. This code is administered by the Department of Water...
General Design for Modifications to Existing Lower Santa Ana Drop Structures
A model study conducted at the Waterways Experiment Station investigated the possibility of utilizing the existing drop structures of the Santa Ana River. Initial tests on selected existing...
Forty Years of Computational Hydraulics?1960-2000
The definition of computational hydraulics as used herein is: the application of numerical methods for the solution of problems of hydraulic flows, largely as practiced by the civil engineering...
Furrow Modeling with Variable Hydraulic Characteristics
A zero inertia furrow irrigation model was developed to run on an IBM-compatible micro-computer. The depth gradient term of the momentum equation is approximated by averaging over the...
Design Storm Selection for Stormwater Management Master Plans
The design rainfall event is an important performance standard for a stormwater management master plan. A stormwater master plan for Virginia Beach, Virginia, is used as a case study to...
Design of Seepage Fields for Stormwater Disposal
Stricker Pond is a shallow twenty-acre kettle hole pond in south-central Wisconsin. The pond receives runoff from a closed watershed that is rapidly undergoing low density residential...
Site Hydrology and Basin Design Using Spreadsheets
The Soil Cover Complex Method which was developed by the Soil Conservation Service is a commonly accepted method of evaluating site hydrology. The solution of this method is facilitated...
Micro-Illudas for Urban Drainage Design
The Illinois Urban Drainage Area Simulator (ILLUDAS) was developed at the Illinois State Water Survey in 1969 and has been available for use on mainframe computers since 1974. An enhanced...
Seepage/Drainage Investigation Colusa County California
High groundwater in the late winter months saturates the soil profile, causing damage to both crops and soil. Sustained water logging severely damages or destroys orchards. It has generally...
