A Comprehensive Tool for Tile Drainage Planning
The objective of the project is to design and develop a set of software tools, building on existing models and computer-assisted procedures, known as an Advanced Decision Support System...

Dam Seepage Analysis Using Artificial Intelligence
The paper discusses an interactive advanced decision support system (ADSS) which is being applied to analyzing seepage from embankment dams. The development of a prototype knowledge base,...

Verification of an Agricultural Land Drainage Model
An agricultural land drainage simulation model was tested under field conditions. The model was found to have several errors. Some of these errors were corrected and the model was tested...

Personal Consultant Series a Step by Step Guide
The paper discusses the Texas Instruments' Personal Consultant Series of expert system development tools, a versatile set of compatible tools for the expert system developer....

A Portable Bowen Ratio System for ET Measurements
The AZET system developed at the University of Arizona is designed to measure evapotranspiration (ET) in arid zone environments, using the Bowen ratio model. The system consists of a set...

Crop Irrigation Requirement Model for Utah
Crop irrigation requirements vary greatly across Utah's wide range of climatic conditions. About 40 electronic weather stations have been established in areas representing...

Collection, Quality Control and Dissemination of Weather Data for Irrigation and Other Operations in an Automated Setting
High technology has made it possible to completely automate the collection of weather data. Care must be taken in designing the automated system to generalize the software components thereby...

Irrigation Scheduling Using Voice Synthesis, the Next Logical Step
An irrigation management program sponsored by the Raft River Electric Cooperative in Malta, Idaho, provided directly measured soil moisture data to selected irrigators each week during...

Computer Aided Hydraulic Design of Open Channels
Over a 10 year period, the computer program, WASURO, was developed by the U.S. Army Corps of Engineers District, Los Angeles (LAD), which utilized many of the criteria of the previously...

Southwestern Drainage Litigation
In this paper, three technical sources of drainage litigation are examined. First, in the overall sparsely but locally densely populated Southwest, there is a severe lack of precipitation...

Flow Measurement Using a Digital Pressure-Time Method
This paper describes flow measurements performed by TVA's Engineering Laboratory as a part of absolute efficiency measurements of the two units at the Great Falls Hydro Plant....

Two-Dimensional Numerical Modeling for Long-Term Sedimentation
Numerical modeling of long-term sedimentation processes in multi-dimensional models is computationally intensive and thus often uneconomical. A statistical superposition technique has...

Stratigraphy of Alluvial Fan Flood Deposits
The purpose of this paper is to describe an engineering geologic technique for assessing the frequency and magnitude of sedimentation events on alluvial fans. The technique is based on...

Model-Prototype Study of Overland Flow
Similarity of overland flow hydrographs was investigated. Similarity ratios based on Froude number modeling were tested by using: 1) computed hydrographs by kinematic wave equations, 2)...

Watershed Runoff Forecasting Technique
Based on historical records of up to 57 years, a computer model was developed to establish the precipitation - runoff relationship for four reservoir systems in the Northeast portion of...

The TENN-V Storm Hydrograph Simulation Model
TENN-V is a computerized, lumped, non-linear stormwater hydrograph simulation model for small unregulated watersheds. The applicability of TENN-V is best established in watersheds of less...

Sensitivity of CUHP-PC Computer Model
The Colorado Unit Hydrograph Procedure (CUHP) consists of effective rainfall reduction and hydrograph convolution processes. The primary assumption is an one-to-one response between rainfall...

Mathematical Modeling of Delta Deposits and Retrogressive Erosion in Reservoirs
A hybrid computer model which simulates mainly delta deposition and retrogressive erosion in reservoirs is described. Basic equations that govern the flow and bed changes used in the model...

One-Dimensional Modeling of Dam-Break Flow
R.W. MacCormack method is used for the numerical integration of Saint Venant equations to simulate the propagation of one-dimensional dam-break wave. The computed water levels are compared...

An Approach for Modeling the Upper Chesapeake Bay
To resolve the bay geometry with a minimum number of grid points, boundary-fitted coordinates are employed. A major question is how to prescribe tidal boundary conditions at the Bay Bridge...
