Predicting the Impact from Significant Storm Events on a Hazardous Waste Site
The Stringfellow Hazardous Waste Site is a former Class I industrial waste disposal facility located near the community of Glen Avon in southern California. In response to community concerns...
A New Set of Equations for Very Shallow Water and Partially Dry Areas Suitable to 2D Numerical Models
When a 2D model is used to compute the flood propagation over an initially dry area some difficulties arise due to the changes in the computational domain as large parts of it are flooded...
A Computerized Open Channel Flow Measurement Device
This is a technical information paper with the intention of introducing a new product. It is not the intent of the author to use this as a marketing tool. However, it is the intent to...
Transport Process of Surface Liquid Spills
A mathematical model simulating the scenarios of surface liquid spills is presented in this paper. This model describes the advance front and recession curves of surface spills based on...
GLFSVIEW - GLFS Product Viewing Application
GLFSVIEW is a menu-driven Visual Basic application running under MicroSoft Windows. This application allows quick downloading, browsing, printing and display of two-dimensional data maps...
Short-Term Forecasts for Lake Erie
Short-term forecasts for Lake Erie were generated by coupling a mesoscale atmospheric prediction system with a lake forecast system. The modeling systems used were The Pennsylvania State...
Nonlinearity and Free-Surface Flow
The Dupuit-Forchheimer (D-F) assumption is commonly considered a viable design criterion for water resources projects and, consequently, Darcy law is used to determine the locus of free...
Nonlinear Hydrodynamic Pressures on Arch Dam Faces
A finite difference method was used to calculate the nonlinear hydrodynamic pressures on the rigid arch dam faces. The arbitrary reservoir shapes were transformed to a regular cubic by...
Design Considerations for Use of Wedge Wire Screens at Surface Water Intake Structures
This paper provides the suggested guidelines for design, construction, operation and maintenance of wedge-shaped wire cylindrical screens used for aquatic biota and trash and debris screening...
Chezy Formula Versus Theory and Common Sense
Using the theoretical concepts of the uniform flow formula and the inverse solution of the Chezy equation it is shown that a channel shape may have considerable influence on the value...
A new approach for the estimation of extreme roughness in torrents by Hydraulic and Photogrammetry
In this paper we present an approach to estimate extreme roughness in torrents based on the transformation of an irregular bed geometry of a torrent reach into a geometrically well determined...
Study of Friction Factors in the Upper Reaches of the Rio Grande
The purpose of this study is to investigate the determination of Manning's roughness in the upper Rio Grande river basin and compare results to other studies where Darcy Weisbach friction...
An Approach to the Calculation Method of Mean Sediment Size
Mean sediment size is an important parameter expressing the characteristics of sediment. Several calculation methods of mean sediment size which are popular at present almost have some...
Step Pool Geometry and Flow Characteristics in Low-Sediment-Storage Channel Beds
Data from two small ephemeral streams in Israel indicate that step pool geometry in bedrock channels is similar, in its salient features, to that in alluvial channels. For steep (>0.10)...
Sediment Transport in Sewers and Design Implications
Extended studies on sediment transport in sewers were conducted at the University of Newcastle upon Tyne and using this new as well as previously available data an attempt has been made...
Determination of Sediment Profile for a Dry Flood Control Basin
A modification of the standard delta profile method was used to estimate the sediment profile in a dry flood control basin. Dry flood control basins do not have a normal operating pool...
Sheet Flow Resistance of Asphaltic Pavements
A statistical study has been conducted by the authors using 400 points of experimental data taken in the 1970's at Texas A&M for sheet flow runoff during artificial rainfall on...
Theoretical study of unstable waves in the rapids of the river
This paper examines how the velocity distribution in free-surface flow affects the kinematic and dynamic velocities of disturbance waves on hillslopes or in high-gradient rivers, thereby...
Protecting a Pipeline
A 30-inch oil pipeline, presently under construction through mountainous terrain in central Colombia, transports petroleum from the Cusiana oil field to the coast. The discovery of the...
Assessment of the Potential for Tectonic Fault Rupture for High-Level Nuclear Waste Repositories
Active faults that extend to or near the Earth's surface may threaten the safety of engineered structures. The threat can be mitigated by appropriate siting and design, which requires...
