Watershed Management in 1985
Today's technology in subalpine watershed management is based on carefully designed watershed experiments beginning with Wagon Wheel Gap in 1909. Subsequent advances in process...
Validation of SWRRB?A Simulator for Water Resources in Rural Basins
The three major components of SWRRB are weather, hydrology, and sedimentation. Processes considered include surface runoff, return flow, percolation, evapotranspiration, transmission losses,...
Simulation of Natural Resource Systems
Desertification, defined as the loss in productive capacity of the land, has spawned research in decision making involving multi-objective situations. In this study, computer simulation...
Modeling Off-Site Impacts
The off-site impacts of a flood water control program were evaluated by applying the SWRRB (Simulation of Water Resources on Rural Basins) model to a treated basin, primarily agricultural,...
A Systematic Evaluation of Hillslope Subsurface Flow: The Effects of Slope Angle and Soil Parameter Variation
A two-dimensional finite element variably saturated flow model is used in conjunction with an automatic mesh generating scheme to simulate hillslope subsurface flow. Slopes from 2% to...
Seepage in the Unsaturated Zone: A Review
This paper briefly reviews the procedures whereby the seepage rate, depth of penetration of nonreactive pollutants, and the depth of the wetting front can be calculated when the assumption...
Computer Applications in Grouting
The first use of computers during foundation grouting was tried by the Bureau of Reclamation on Ridgeway Dam in Colorado. It was very useful in monitoring real time down hole conditions...
Acoustic Emission Monitoring of Grout Movement
This paper describes the acoustic emission (AE) method in general, and in particular the AE system which holds significant promise in this regard. Used was a multichannel AE system which...
Grout Slurries?Thick or Thin?
In this paper some recent experiences in dam grouting in several countries are discussed where bentonite or Intraplast additives were used to control sedimentation, viscosity, grout density,...
Computer Modeling of Roof Support
The Bureau of Mines is using a full-scale geotechnical model of a 15-foot-wide (4. 6-m) coal mine entry in correlation with computer finite-element analysis at its Spokane Research Center...
Prediction of Highway Construction Noise Levels
A model for the prediction of noise levels from highway construction operations has been developed under sponsorship of the Federal Highway Administration (FHWA). Noise sources are geometrically...
Dynamic-Fatigue Response of Continuous Composite Bridges
The dynamic response of continuous composite bridges and the influence of fatigue loading at resonance frequency on the structural response are investigated. It is shown that cracking...
Strength of Biaxially Loaded SRC Columns
The paper presents the results of an experimental study on the elasto-plastic behavior of 'Steel reinforced concrete (SRC)' columns subjected to biaxially eccentric...
Composite and Mixed Construction in Czechoslovakia
Various composite and mixed systems have been used in Czechoslovakia. Special attention is focused on design methods, effective construction, and material savings. Current developments...
Checking Off CADD Priorities
Diving head on into new computer aided design and drafting (CADD) hardware and software without considering their effects on firm or university's operation is as bad as ignoring...
Computer Impacts on Water Resources Engineering
Computation capability has increased by a factor of one million over the past 30 years and has contributed greatly toward data management and the application of available technology to...
Computers in a Planning Context: Another Reality
Over the past twenty years water resources planning has seen a great increase in the development of computer methods of analysis. This has transformed the way the hydrology, hydraulics,...
Maximum Water Source Utilization Using Lotus 1-2-3
This paper discusses the use of microcomputers to determine the optimum mix of sources for the Fargo-Moorhead area's water supply network. The area's major water...
Personal Computers and Stormwater Management Programs
Urban flooding and drainage problems are the result of complex interactions between natural and man-made systems. Comprehensive analysis of the hydrologic characteristics of these problems...
Micro Use in Water Management in the Brazos Basin
The Brazos River Authority, an agency of the State of Texas created to conserve and develop the surface waters of the 42,000 square mile (110,000 km) Brazos River Basin, is in the midst...
