Urban Development on Alluvial Fans
An increasing number of developments has been planned in areas subject to flood hazards. To protect developments from flood damage and to prevent accumulated negative effects on floodplains,...
On Deciding Between the Use of Engineering Standards and Risk Analysis
Risk analysis offers advantages for the optimal design and maintenance of infrastructure, but it is not always practical to apply due to the nature of certain types of infrastructure....
?H and ?4C as Tracers of Ground-Water Recharge
Surface spreading of water from the Santa Clara River is used to recharge aquifers underlying the Oxnard Plain. These aquifers are divided into an upper system about 400 feet thick, and...
Importance of ET on Colorado River Water Quality
Salinity is a major problem in the Colorado River. About 37 percent of the salt loading is contributed by irrigated agriculture activities. Deep percolation and seepage from irrigated...
Agricultural Impacts on Surface Water via Ground Water
Three years of ground and surface water quality monitoring data collected from one site in the mid-Atlantic coastal plain are presented. These data suggest that delivery of P from ground...
Gradual Development of Bores in Canal Systems
Modern computer programs for modeling unsteady flow in open channels are typically constructed using a momentum conserving form of the Saint Venant equations. This allows computation of...
Climate Change and Water Management Flexibility
Changes in regional climate expected to occur as a result of the accumulation of greenhouse gases may have significant impacts on water resources. In this paper, I examine the sensitivity...
Water Data of the International Boundary and Water Commission
The International Boundary and Water Commission, United States and Mexico (IBWC) was created by the Treaty of March 1, 1889, between the Governments of the United States and Mexico. Principal...
Modifications to Coal Pier 6 Made Necessary by a Deeper Channel
In 1987 it became apparent to the Norfolk Southern Corporation that the U.S. Army Corps of Engineers proposed dredging of the Norfolk, Virginia Harbor would become a reality. Coal Pier...
Environmental Monitoring and Operator Guidance System (EMOGS) for Shallow Water Ports
Port facilities have increasingly been required to accommodate longer and deeper draft ships. Existing approaches to many ports consist of long shallow channels which can make transits...
Barbers Point Harbor: A Unique Solution for Port Upgrade
A remote-controlled model of a C9 containership was used to evaluate the navigability of existing harbor and entrance channel conditions in a three-dimensional physical model of Barbers...
Ship Simulation of the Houston Ship Channel, Houston, Texas
The Houston Ship Channel (HSC) consists of approximately 65 miles of improved deep-draft channels. The present channel is 400 ft wide and 40 ft deep at mean low tide for most of the channel...
Draft Chapter 2?Planning and Design Guidelines for Small Craft Harbors?Entrance Design and Breakwaters
The paper will present a very preliminary draft of the second chapter of an ASCE manual that is currently being developed. The new manual is entitled Planning and Design Guidelines for...
Spatial Decision Support System for Toxic Spill Modeling in the Ohio River
Spatial decision support systems (SDSS) are hardware-software systems that incorporate spatial analysis and modeling in a workstation environment. The Ohio River Valley Water Sanitation...
Rock Creek?Cresta Sediment Management Plan
Pacific Gas and Electric Company (PG&E), an investor owned utility serving northern and central California, is working to manage sediments at its Rock Creek - Cresta Hydroelectric...
Computer-Aided Support for Water Quality Modeling of the Russian River
A computer-aided support system for operation of the QUAL2E-UNCAS modeling packaged has been developed for modeling of the Russian River, California. The system has been created under...
Modified QUAL2E Modeling of a Stream Acutely Impacted by Photosynthesis and Respiration
The QUAL2E model was modified to account for time variable headwater conditions and the photosynthesis and respiration of attached aquatic plants. With these modifications, a stream that...
Two-Dimensional Hydraulic Analysis of the Owensboro Bridge and Approaches
The Kentucky Transportation Cabinet, Department of Highways, is working with the Indiana Department of Transportation and the Federal Highway Administration to plan, design, and construct...
Dry Creek Watershed Flood Control Plan: A Case Study
This paper describes the development of the Dry Creek Watershed Flood Control Plan. This study was conducted to quantify the extent of the existing and future (buildout) drainage problems...
Extended Experience with a Short-Term Hydropower Scheduling Model in New England
