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...

Platte River Irrigation Development: Hydrologic Myths
Several proposed municipal and irrigation developments in Wyoming, Colorado and Nebraska could impact flows along the Platte River in central Nebraska. Opposition to these projects is...

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...

Calibration of Water-Velocity Meters
The U.S. Geological Survey, Department of the Interior, as part of its responsibility to appraise the quantity of water resources in the United States, maintains facilities for the calibration...

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....

Analysis of Progressive Development on Alluvial Fans
Flow on alluvial fans is considered to be somewhat unpredictable and complex, experiencing high velocities, avulsions, erosion, and deposition causing a dynamic topography with flooding...

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)...

Model Complexity Required to Maintain Hydrologic Response
An increasing number of practitioners are using distributed hydrologic models employing kinematic routing. Watersheds are typically represented by a set of overland flow plane and channel...

Comparison of Peak Discharges of Hydrologic Models
The objective of this paper is to evaluate the predictive capabilities of hydrologic models in estimating the magnitudes and frequencies of flood peaks by comparing them with the values...

Evaluation and Testing of Storm-Event Hydrologic Models
Hydrologic models considered for this evaluation include: Areal Nonpoint Source Watershed Environmental Response Simulation (ANSWERS); a kinematic erosion model (KINEROS); Watershed and...

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...

Runoff Simulation, Homestake II Project
Wetlands issues raised in connection with the proposed Homestake II Project required an extremely detailed evaluation of basin hydrology. The Subalpine Water Balance Model (WATBAL) was...

Finite Element Modeling in Free-Surface Hydromechanics
A finite element semi-discrete approximation is applied to the conservation law form of the two-dimensional, depth-averaged free-surface Navier-Stokes equations governing incompressible...

Task Committee Activities on Microcomputer Software in Urban Hydrology
This Task Committee of the Surface Water Hydrology Committee has been established with the primary objective of developing an inventory of presently available software and to recommend...

Urban Drainage Calculation Limits for Small Areas
This paper discusses the selection and application of hydrologic techniques in the design of stormwater facilities, with particular emphasis on the selection of hydrologic procedure for...

Federal Microcomputer Software for Urban Hydrology
The purpose of this paper is to describe the development, availability, and general use of selected urban hydrology microcomputer software developed by: U.S. Soil Conservation Service...

Evaluation of Diffusion Models for Flood Routing
A study has been conducted to define the range of conditions with respect to hydrographs and channels encountered by SCS engineers in flood plain/flood control projects and to test two...

Hydrodynamic Response of an Estuary to Storm Forcing
Previous work on the response/sensitivity of an estuarine hydrodynamic model to the choice of model parameters is extended to include a preliminary consideration of wind-generated waves....

Modeling of a Low Head Hydroelectric Project
In order to shorten the time to develop a hydroelectric project at the Corps of Engineers Hannibal Lock and Dam on the Ohio River for the City of New Martinsville, West Virginia, a turnkey...
