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...
Bureau of Reclamation Downstream Hazard Classification
An overview of the downstream hazard classification process used by the Bureau of Reclamation (Reclamation) and other U.S. Department of the Interior (DOI) agencies for the safety of dams...
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...
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...
U.S. Geological Survey Bedload Sampling Policy
During the late 1960's, the U.S. Geological Survey's (USGS) Water Resources Division (WRD) developed the Helley-Smith bedload sampler. Since then, the USGS and the Technical Committee...
A Model of Mixing in a Stratified Tidal Flow
We will describe a simple model of vertical mixing in a stratified tidal flow that might be observed in shallow estuary like San Francisco Bay. The model flow is driven by a specified...
