Environmental Design of Channels?Can It Be Done?
The importance of environmental features to channel design is generally accepted and procedures for incorporating environmental features into flood control channel design have been developed....

Stable Channel Analytical Design Method
The Flood-Control Channels Research Program is being conducted at the US Army Engineer Waterways Experiment Station to develop systematic methods for design of stable channels for small...

Failure Modeling of Hydraulic Systems
Techniques of survival analysis are investigated for modeling the failure of hydraulic systems. The Proportional Hazards Model has the advantage of being able to separate the effects on...

Optimal Design of Highway Drainage Structures
Hydraulic design of a bridge or culvert using a risk-based approach is to choose among the alternatives the one associated with the least total expected cost. In this paper, the risk-based...

Conservativeness in Hydraulic Engineering Studies
Hydraulic engineers routinely make a variety of assumptions during the course of a study. Assumptions, once made, usually become incorporated into the fabric of the study and are seldom...

Design and Construction of Soil-Cement Drop Structures
Soil-cement has been used as an effective and economical slope protection material for embankment dams and stream banks. This paper describes the use of soil-cement in the construction...

Evaluation of the ARS Low Drop Grade Control Structure
The ARS low drop grade control structure was developed by Little and Murphy to provide efficient energy dissipation and effective grade control for streams in northern Mississippi. The...

Guard Gate Tests at Tieton Dam
The emergency gate hoist system on the guard gates at Tieton Dam, near Yakima, Washington, was tested as part of the United States Bureau of Reclamation Safety Evaluation of Existing Dams...

Innovative Spillway Design
The Lake Alan Henry Dam, near Lubbock, Texas, will consist of an earth filled embankment, a service spillway and an emergency spillway. The service spillway is designed to handle flows...

Scale Effects of Overflow-Oriented Hydraulic Parameters for a High Dam
This paper presents the findings of prototype observation and model verification on the surface velocity, the range of nappe jetting, and the diffusion regime of the discharged flow related...

Conservation Properties of Flow Simulation Models
The fundamental equations of fluid mechanics and hydraulics posses certain integral properties which should be maintained by their discrete analogs. In this paper the conservation properties...

Computational Open-Channel Hydraulics for Movable-Bed Problems
As a major branch of computational hydraulics, notable advances have been made in numerical modeling of unsteady open-channel flow since the beginning of the computer age. According to...

A Generalized Diffusion Wave Flood Routing Model
A generalized diffusion wave model for flood routing is presented. The model can incorporate detailed data on natural cross sections and river bed geometry. An accurate numerical method...

Development of a Computer Aided Decision Process for Channel Rehabilitation and Watershed Enhancement Techniques
To assist the engineer in planning and design of channel stabilization measures, an expert system (CADWET) was developed using a commercially available expert system shell program. The...

Use of Linear Programming for Hydraulics Problems
Water is becoming a more and more precious commodity worldwide with each passing day. At the same time, the optimum and most productive solutions to water control and utilization are becoming...

Equivalence Between Regular and Irregular Waves in Movable-Bed Models
Laboratory experiments were conducted to evaluate various irregular wave parameters to determine which provides the best match for the regular wave parameter used to develop design guidance....

Pump Selection Program and a Better User Interface
Numerous highly innovative computer solutions to engineering problems are of little use to the practicing engineer because these programs are not supported by adequate user interface....

Compact Pump Sump Design
This paper details the design criteria chosen to construct a pump sump within several on-site constrictions. The physical size restrictions of the site necessitated the construction of...

Hydraulic Analysis for the Shot Tower Subway Station Beneath the Jones Falls
The objective of the hydraulic analysis is the formulation of a strategy to safely accommodate the construction of the Shot Tower Metro Station beneath the existing Jones Falls. The hydraulic...

Comparison of Flush and Chamber Mounted Dynamic Pressure Transducer
Modeling of hydraulic structures often includes the measurement of dynamic pressure fluctuations. The accuracy of the pressure measurements depends upon the geometry of the tap. Flush...
