Developing a User Friendly System for Water Distribution Management Applications
A hydraulic computer model of a water distribution system that can be updated with current billing (customer meter readings) information automatically. The model was calibrated with field...
Vegetal Protection of Embankments and Spillways
Recent advances in the application of tractive stress to the design of grass-lined open channels are used to develop a tentative procedure for analyzing the hydraulic performance of vegetated...
Limitations of Saint Venant Equations to Model Flood Waves
The subject of this paper is in direct contrast to all previously known research efforts. Previous effort has focused on simplified forms of Saint Venant using approximate routing models...
Modeling Unsteady One Dimensional Open Channel Flow Using the Slope Friction Form of the Saint-Venant Equations
The flow of water in open channels has been an important research topic for many years. In 1871, B. De. Saint-Venant published a set of equations that attempted to quantify the physical...
Improved Robustness of the NWS DAMBRK Algorithm
The combination dam breach and flood routing numerical model called DAMBRK has been developed by the National Weather Service (NWS) for forecasting river flooding events (Fread, 1984)....
Evaluting the General Well Function
The closest thing to a mathematical function that maps well discharge to drawdown has been Jacob's equation, caled the step-drawdown equation. However, this equation assumes the drawdown...
Alternative Methods for Representing Sinkholes in Three-Dimensional Ground Water Flow Models
Two methods of representing the sinkholes in central Florida were investigated with a three-dimensional finite element model recently developed by Camp Dresser & McKee Inc. Both...
Ground Water Flow Simulation in a Small Drainage Basin
This paper describes the development and use of a numerical simulation approach for predicting ground water flow in a small drainage basin in southern California. The purpose of the modeling...
Numerical Model Analysis of Sedimentation Problems at Lock and Dam 1, Red River Waterway
This paper addresses the numerical modeling techniques used to identify the conditions and parameters affecting sediment deposition at Lock and Dam 1. Two-dimensional finite element models...
Regulatory Floodway Width Estimation
A simple algebraic equation is presented for determining the width of the regulatory or designated floodway. The equation shows that for a given ratio of the permissible increase in flood...
Mathematical and Laboratory Modeling of Transport in Partially Saturated Soils
The salient features of a two dimensional flow and solute transport model in partially saturated soils are presented. A Galerkin finite element approach for the numerical solution of the...
Two-Dimensional Groundwater Transport Subgrids in a 3-D Flow Model
The USGS Modular 3-D Finite Difference Ground-Water Flow Model by McDonald and Harbaugh (MODULAR) simulates ground-water flow in three dimensions by breaking the modeled region into several...
On the Selection of Sediment Transport Equations
Existing sediment transport relationships have been calibrated under a certain range of experimental conditions which can be described by the dimensionless grain size, the mobility number,...
Computational Modeling of Sediment Transport in Kachemak Bay
The tide-generated flow circulation in the Kachemak Bay of Alaska was simulated numerically using the Multi-Leveled Finite Element Model originally developed by Kawahara of Japan and recently...
Hydraulic Model to Improve Debris-Handling Capability of Waterford Unit 3 Intake Canal
A 1:30 scale model was used to test the effectiveness of various modifications to the Waterford Unit No. 3 intake canal. The objective of the study was to assist in the development of...
