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...
Mathematical Modeling of the Sacramento-San Joaquin Delta
The Sacramento-San Joaquin Delta consists of a complex network of interconnected channels, open bodies of water, dead-end sloughs, export pumps, reservoirs, tide gates and irrigation pumps....
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...
Accounting for Antecedent Conditions in Seawater Intrusion Modeling?Applications for the San Francisco Bay-Delta
A new method for predicting salinity variation with outflow is developed for the western Sacramento-San Joaquin Delta in northern California. A simple routing equation is used to calculate...
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...
Removal of Tidal Fluctuations from Pumping Test Data
A simple technique for removing tidal fluctuations from drawdown data was examined. This technique relied simply upon transforming measured surface water level data to fit the pretest...
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...
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...
Protecting the Boca Raton Outfall Before and After Hurricane Andrew
A critical factor for the success of an ocean outfall is its ability to remain intact and functional for many decades of service, despite extreme episodes of wave attack and beach erosion....
Reclamation's Review of Operation and Maintenance Program
The U.S. Bureau of Reclamation (Reclamation) is responsible for protecting the Federal investment in over 300 water storage and conveyance facilities in the 17 Western States. Reclamation's...
Wetland Restoration in the Dutch Dune Area
Interference by man has affected the natural Dutch dune area seriously. The harmful effects of drinking water supply activities include low groundwater tables in the valleys, unnatural...
Annual Oscillation of Mean Monthly Water Levels at U.S. Ports
The annual variation in water level is not widely recognized among engineers. It could effect the selection of design ship channel depth or marina channel dredging, and tidal wetland creation...
Modeling the Operation of a Water Quality Reservoir and its Effect on the Sacramento-San Joaquin Delta
The methodology used to model the operation of a 100,000 acre-feet (123 million cubic meter) water quality reservoir in Contra Costa County, California is described. Planning studies integrated...
Quantification of Uncertainties in a Water Quality Model with Application to the Sacramento-San Joaquin Delta
A methodology is described that allows a quantitative verification of water quality models. The methodology provides a quantitative analysis of model accuracy that takes into account different...
New Methodology for Optimization of Freshwater Inflows to Estuaries
The objective of this paper is to present a new methodology for determining the optimal fresh water inflows into bays and estuaries to maximize fish harvest while satisfying the freshwater...
Relationships Between Flow and Benthic Communities
Current flows can affect directly factors critical to the survival of benthic communities, including the availability of food and nutrients, the chemical quality of water surrounding benthic...
Reclamation's Design Process of Early Warning Systems for Dam Safety
This paper discusses the Bureau of Reclamation's process for designing the detection and decision making components of an Early Warning System (EWS) for dams with hydrologic deficiencies....
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...
