Infiltration of Water to the Ground in a Flood-Control Reservoir with Seepage
As storm water management in urban area with increasing amount of runoff, flood-control reservoir with the bed having large permeability to enrich the groundwater is considered. A dynamical...
Water Resources Planning and Management
The proceedings of the 16th annual Water Resources Planning and Management Conference, which was held on May 22-24, Sacramento, CA, consists of four page extended abstracts for about 200...
Boundary Element Methods in Structural Analysis
Tutorial and state-of-art aspects of the Boundary Element Method (BEM) are combined with applications in structural analysis in order to provide information about the advantages of this...
Bullwinkle
The 1989 Outstanding Civil Engineering Achievement is an offshore oil production platform named Bullwinkle, a structure in the Gulf of Mexico that is taller than the Sears Tower, shaped...
Predicting Human Instability in Flood Flows
The delineation of high flood hazard zones within a flood plain is usually independent of the parameters that constitute a life threatening situation. In order to define human instability...
Comparison of DAMBRK With DWOPER for Computing Water Surface Elevations at Stream Junctions
The National Weather Service computer programs DWOPER (Operational Dynamic Wave Model) and DAMBRK (Dam-break) are one-dimensional models using an implicit finite difference method of solution...
Peak Outflow From a Breached Embankment Dam
A relation for rapidly predicting the peak outflow rate from a breached embankment dam has been presented. The prediction equation is based on reliable data from 19 embankment dam failures...
A Frictional Resistance Model for the Analysis of Non-Point Source Pollution Processes
This study experimentally investigated the effect of a permeable bed for steady, laminar and smooth turbulent free surface flow on the Darcy-Weisbach friction factor. Flow velocities and...
Regional Flood Plain Management
A flood plain management plan for White Rock Creek in the Cities of Dallas and Plano, Texas was developed. New technologies such as three-dimensional topography, CADD, and remote sensing...
Interfacial Instability in Highly Stratified Flows
The stability of highly stratified shear flows is dependent on several parameters including the thickness of the interfacial transition layer. Experimental results show that the thickness...
Estuarine Mud Flow Modeling
This paper presents a model for the simulation of selective withdrawal of estuarine mud. This research is part of the investigation of the design of a mud pumping plant as an alternative...
Numerical Model Studies of Wetland Hydraulics for Bolsa Bay, California
The Bolsa Bay area, near Los Angeles, presently consists of three distinct regions separated by two sets of culverts. A development is being considered, in which a balance between housing...
Improved Numerical Analysis of Steady Water Surface Profiles
As well as HEC-2 and similar models serve the profession, problems exist with their application. In general, inflexibility of use and inaccuracies around transitions between subcritical...
Numerical Modeling of Hydraulic Jump
Boussinesq equations describing one-dimensional unsteady, rapidly varied flows are numerically integrated by using a second-order and a fourth-order accurate explicit finite-difference...
General Formulation of Best Hydraulic Channel Section
The best hydraulic channel section is determined by using Lagrange's method of undetermined multipliers. The approach presented is more general & easier to apply than...
The Turbulent Wake of a Recirculating Eddy in Shallow Waters
The wake, created by injecting dye into the recirculating zone of a sudden lateral expansion in a shallow open channel, is examined experimentally for a range of bed-friction influence....
Cellular Automaton Simulation of Viscous Free Surface Fluid Dynamics
It has been demonstrated elsewhere that the simple interaction of a two dimensional field of discrete particles traveling on a regular lattice yields large scale behavior closely approximating...
Performance Characteristics of Compound Weirs
A theory is outlined which helps to explain the flow over compound weir under free overfall conditions. Experiments on twelve weirs of three sets with different dimensions are shown to...
Analysis of Storm Sewers During Surcharge
A mathematical model based on a lumped system approach is presented to simulate unsteady flow in storm sewers during surcharge. The model equations and method of solution are presented....
Plans for National Flood Frequency by Microcomputer
Work is underway on a planned microcomputer program that will include about 1500 prediction equations for 214 flood regions of the United States and Puerto Rico. The program will include...
