Scour Study for Bridge Design on Temecula Creek
Channel-bed scour was studiedfor the proposed new Pala Road Bridge on Temecula Creek in Riverside County, California. In order to determine the general scour, sediment transport and potential...
Development and Application of a Dual Drainage Model for the Wethersfield Area of the City of Hartford, Connecticut
A combined system, with overflows, existed in the City of Hartford, Connecticut. Although effective in the context of design standards prevailing at the time of its original design, the...
Pipe Network Analysis and Design in Developing Regions. Case Study: Novokuznetsk, Siberia
Pipe network analysis, design and optimization in developing countries poses some unique problems, yet, is of paramount importance. Under these conditions, there is frequently only sparse...
Aquifer Transmissivity Computations Based on Data from Pump-and-Treat Facilities
Contamination from petroleum hydrocarbons spilled from USTs is a concern in urban areas that depend on shallow unconfined aquifers for their water supply. Studies on the transmissivity...
Managing Great Lakes Water Levels: An International Partnership
During this century, the levels of two of the Great Lakes have been regulated; Lake Superior since 1921 and Lake Ontario since 1960. The regulation is directed by the International Joint...
System of River Floods Warning in Ukraine
The diversity of climatic, geomorphologic, and soil conditions causes significant space differences in the conditions of river flood formation in Ukraine. The Carpathians region is the...
Application of GIS Technology to Floodplain & Habitat Analyses
A long-term flood control and maintenance plan for the Mojave River, located in southern California, is currently being developed to satisfy permit requirements for state and federal regulatory...
Design of Riparian Habitat Replacement in Active Floodplains
Conventional flood control engineering techniques and approaches that have been traditionally been applied are now challenged by the public and no longer readily available as floodplain...
Optimizing Municipal Wastewater Treatment in Cold Climates: Scale, Process and Benefits
Although conventional wisdom demands large, centralized facilities for municipal sewage treatment, much has recently been made of the potential of low tech, decentralized systems for wastewater...
Physical Distribution System Models for Assessing the Impact of Water Quality on Regrowth and Corrosion
Over the past several years, there have been several new and proposed Safe Drinking Water Act (SDWA) regulations that will require many water utilities to modif treatment operations to...
Use of Channel Forming Discharge Concepts for Flood Control Channel Design
Evidence suggests that for perennial and ephemeral rivers that are in regime, bankfull flow is strongly correlated with channel morphology. Evidence suggests that this discharge is also...
Reversibility Measures for Sustainable Decisions
Increasing stress on the environment and current norms of sustainable development have prompted the formalization of new approaches to decision making. This may be achieved through the...
Pollutant Transport Across Porous Stream Beds
The presence of porous streambeds generates a significant interaction between the main stream flow above it and the flow through the porous sub-stratum. This coupling affects both flows,...
Simulation of Perilithic Algae as a Biofilm and Its Interaction with the Water Column
A one-dimensional bioflim model has been constructed consisting of a particulate phase of algae and inert material and diffusive transport of nutrients and oxygen. Also included is mass...
Uncertainty in Comparative Analysis with Continuous Nonpoint Source Pollution Models
There have been few attempts to quantify the impact of parameter uncertainty in comparative analysis with continuous nonpoint source pollution models. This paper presents the results of...
Flash Floods and Their Warning in Vietnam
At present, in Vietnam flash floods occur on small mountainous catchments and cause considerable damage to lives and property, to the national economy, and to the environment. The flash-flood...
A Screening Level Model for Estimation of Vadose Zone Leaching and Saturated Zone Mixing: VLEACHSM
A screening level computer model has been developed for the evaluation of pollutant migration through the vadose zone and subsequent mixing within the saturated zone. The model, called...
A GIS Sewer Database for a University Campus
The development of a geographic information system (GIS) based sewer network database for the Purdue University campus in West Lafayette, Indiana, is discussed in this paper. The database,...
Non-Federal Flood Control Works Inspection Program
This paper presents a general description of the Non-Federal FCW Inspection Program and results obtained from the evaluations already completed. A discussion of the GIS package for data...
Floodplain Analysis of the Lower Santa Margarita River in Camp Pendleton Marine Air Base, California
Floods of 1993 caused extensive flooding of the Santa Margarita River, and significant damage to Camp Pendleton. A floodplain analysis was performed including an assessment of recent flood...
