Physical Habitat Simulation and the Moveable Bed
One objective of an instream flow analysis is to quantify a flow that will maintain the existing channel and/or flush fine material from the bed. Five empirical approaches to determine...

Trash Busters ? A Comparison of Screening Structures for Irrigation Systems
Several irrigation districts in the Pacific Northwest have recently installed screening structures for use in removal of trash from canals, rivers, or reservoirs. Some of the screens have...

Advancements in Aerodynamics, Fluid Mechanics and Hydraulics
The theme of these Proceedings is Advancements in Aerodynamics, Fluid Mechanics, and Hydraulics. As indicated by the title, the subject crosses disciplinary boundaries and deals with flow...

Available Compaction Equipment
When discussing available compaction equipment we must keep in mind the purpose of compaction. Compaction is the art of artificially increasing the density or increasing the unit weight...

Three-Dimensional Boundary Element Techniques for Moving Boundary Problems
The boundary element method (BEM) is a powerful numerical method well suited for a wide variety of engineering problems. The numerical computations are performed only on the boundary of...

Hydrologic Simulation for Reservoir Development
Potential changes in the Manasquan River basin hydrologic budget were assessed with the Hydrological Simulation Program in Fortran (HSPF). The HSPF results were used to assess the reliability...

Microcomputers and Design Codes: A Case Study
A microcomputer analysis of the thermal stress problem in reinforced concrete box sections was conducted. An explicit finite difference algorithm for a one-dimensional heat flow analysis...

Real Time Data Acquisition in Structural Testing
The process of data collection in real time for structural engineering can be generalized into a process called the real time sequence. The sequence has three major phases: preliminary...

Groundwater Modeling: Selection of Computing Systems
Results are presented for ten microcomputer systems evaluated with respect to system performance in solving a test case three-dimensional groundwater flow problem. The model used was the...

Improved Urban Traffic Flow Through Signal Re-timing?California Experience
The California Energy Commission (CEC) has initiated a new program to re-time all of the 20,000 interconnected traffic signals in the state, the first of its kind in the United States....

The Electronic Road Pricing System in Hong Kong
This paper addresses the traffic congestion problem and issues relating to the experiment of the world's first pilot scheme on Electronic Road Pricing System in Hong Kong....

Negatively Buoyant Flow in a Diverging Channel
Negatively buoyant (plunging) flow from a horizontal, constant width channel into a diverging channel has been studied in the laboratory. The study was undertaken to provide information...

Proportional Weirs for Stormwater Pond Outlets
Many jurisdictions mandate that new developments must not cause runoff to flow downstream, during and after rainfalls, at rates higher than preconstruction. A common for controlling runoff...

Simulation of Hillslope Hydrologic Response to Snowmelt in Southwestern Idaho
A two-dimensional, variably saturated porous media flow model was applied to vertical hillslope cross section on a first order study basin in southwestern Idaho. The dominant source of...

The Role of Multiple Level Hydrologic Analysis in Watershed Management?A Case Study in Trinidad
An accurate estimation of peak flood flows and its correlation with existing and future land use are basic requirements for the scientific management of Watersheds. An accurate estimation...

Prediction of Soil Water Properties for Hydrologic Modeling
Water flow in soils can be characterized for many boundary and initial conditions by solving governing differential equations. Thus, a physically consistent means of quantifying water...

Source Area Variability During Peakflow: A Function of Antecedent Soil Moisture Content
An attempt was made to identify the source areas contributing to peakflow and to quantify the relative importance of each source area under various antecedent soil moisture (ASM) conditions....

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...

Use of Asphalt in Treatment of Dam Foundation Leakage, Stewartsville Dam
This paper presents the recent development and application of a hot asphalt grouting technique used to stop a 5,000 Imperial Gallons Per Minute (IGPM) (22,000 lpm) dam leakage under full...
