Multi-Disciplinary Strategies for Flood-Plain Restoration at the River Rhine
Within the scope of a multi-disciplinary concept, aims and measures of ecological and water resources management at the river Rhine in Nordrhein-Westfalen (Germany) are analyzed. Especially,...

Development Strategies for Botswana's Okavango Delta
This paper contrasts two different development strategies for the Okavango Delta - the Government of Botswana's Southern Okavango Integrated Water Development Project and an IUCN-proposed...

Wetland Management in Britain: A Comparative Approach
Wetland management in the United Kingdom is in an early stage of development. The importation of management aims and techniques from other countries with more advanced programmes is an...

Application of Four Point Model to the Sacramento-San Joaquin Delta
Four Point (Delong et al. 1993) is a finite-difference, one-dimensional, unsteady, open channel, hydrodynamic model. The Modeling Support Branch of the Division of Planning, California...

The DWR Delta Data Assembly Project
While much progress has been made in advancing the theoretical development of estuary models, relatively little effort has been made in improving the quality and quantity of historical...

A Unified Optimization?Simulation Aquifer Management Model
The optimal management scenario for a groundwater production system represents a delicate balance between the water production operational schedule, which will result in the least demand...

An Optimal Parameter Estimation Model for Groundwater Resource Management
An optimal parameter estimation model is developed to identify the locations of wells, to determine pumping magnitude, and to calculate transmissivity coefficients in a confined aquifer...

Quality Control and Quality Assurance Plan for Bridge Channel-Stability Assessments in Massachusetts
A quality control and quality assurance plan has been implemented as part of the Massachusetts bridge scour and channel-stability assessment program. This program is being conducted by...

In-Depth Scour Evaluations for Bridges in Pennsylvania
The scour evaluations described herein have been prepared for the Pennsylvania Turnpike bridge crossing the Unami Creek, the first bridge studied in a series of nineteen major Turnpike...

Hurricane Andrew in South Florida: Preparing a Water Management System for Disaster
This paper analyzes Hurricane Andrew from its beginning as a tropical storm to the powerful force that it later became. The careful monitoring that took place throughout its transformation...

Hurricane Andrew in South Florida: Steps to Recovery and Lessons Learned
This is the second part of a two-part paper which analyzes the development and impact of Hurricane Andrew in South Florida. The paper specifically deals with the experiences of the South...

Risk Analysis of River Bridge Failure
The proposed procedure to determine the risk of river bridge failure is based on observations and analysis of river bridge failure data of more than 300 U.S. bridges, 180 South African...

Using Threat to Life Studies to Guide Dam Safety Decisions
Ensuring that Bureau of Reclamation (Reclamation) dams do not present unacceptable risks to public safety, prosperity, and welfare serves as a primary objective of Reclamation's Safety...

Economic Aspects of the Bureau of Reclamation Safety of Dams Program
The paper briefly examines economic aspects of the Bureau of Reclamation (Reclamation) Safety of Dams (SOD) program evaluation process. Procedures described include the downstream damage...

Emergency Action Plan
Although most dam owners have a high level of confidence in the structures they own and are certain their dams will not fail, the Bureau of Reclamation (Reclamation) included, history...

Yolo Bypass Wetlands?Impact Investigation
Approximately 20 square kilometers of wetland facilities are proposed to be installed within the Yolo Bypass of the Sacramento River Flood Control Project. A hydraulic impact investigation...

Operational and Structural Optimisation of Hydraulic Structures for Light Liquid Removal
The removal efficiency of light liquid separation schemes is determined by the hydraulic inflow conditions, the inflow fluid properties and the separator hydraulics. The relating set of...

Emergency Protection, San Luis Rey River Aqueducts
A calibrated hydraulic computer model (FLUVIAL-12) was used to predict flood damage potential at the two San Diego Aqueduct river crossings in northern San Diego County. Model results...

Erosion Protection at Hydraulic Structures: A Report From the Task Committee
In 1991 the ASCE Hydraulics Structures Committee formed a task committee on Erosion Protection at Hydraulic Structures. The purpose of the committee is to determine current practices in...
