Active Control of Structures with Soil-Structure Interaction
The objective of this paper is investigate the effect of soil flexibility on the performance of the active control system for seismic-excited buildings. By using the critical-mode control...

Simultaneous Design and Location of Actuators
A chance constrained model for determining optimal dynamic control parameters for structures subjected to probabilistic forcing amplitudes is presented. Optimal feedback control parameters...

Integration of SCADA and GIS Technologies in Jefferson Parish, Louisiana
Due to its physiographic setting in the delta region of the Mississippi River, a majority of the inhabited lands in Jefferson Parish, Louisiana are below local mean sea level and much...

Low Stream Flow Frequency Analysis with Ordinary and Tobit Regression
In order to estimate the low-flow quantiles at ungaged sites, it is necessary to estimate low-flow quantiles at gaged sites. Two linear regression methods, denoted NR and NE, are compared...

Application of Kalman Filtering to Groundwater Flow in Finite Heterogeneous Aquifers
A stochastically based methodology using Kalman filtering is presented for the optimal estimation of hydraulic properties in finite heterogeneous aquifers. This is achieved by applying...

Corps of Engineers Water Control Data Systems for the 90's
Corps of Engineers water control data systems encompass all of the instruments, equipment, computers, and software used to collect and use environmental data in real-time water control...

A Prototype Distributed Processing System Water Control Data Processing at Tulsa District U.S. Army Corps of Engineers
The Tulsa District, Corps of Engineers operates 50 multi-purpose reservoirs controlling runoff from all or parts of 7 states. These reservoirs are operated for flood control, water supply,...

Downstream Danger from Sudden Discharges of Water
The sudden, unexpected release of water by hydropower facilities poses a threat to fishermen and boaters immediately downstream. The characteristics of the danger can be identified, however,...

Water Supply Impact Analysis of Proposed Water Quality Control Plan for Salinity for San Francisco Bay and Sacramento-San Joaquin Delta Estuary
This paper presents the procedures and techniques employed as part of the Bay-Delta proceedings to evaluate the water supply impacts of various proposed flow and water quality objectives...

A Bivariate Stochastic Reservoir Model
A bivariate distribution of peak flows and volumes is derived taking into account their correlation structure. This distribution is then used to derive reservoir operation curves which...

Field Measurement of Surface Flows in Shallow Estuaries
This paper summarizes our first-year results of an ongoing multi-discipline project, which examines the physical processes of wetlands erosion and loss in coastal Louisiana. Our task is...

Flushing Characteristics for Harbor Planning
A two-dimensional hydrodynamics model was used to understand the circulation and transport patterns in Keelung Harbor, Taiwan. The calculated hydrodynamics information was used to determine...

Summary of Stormwater Quality Management Practices
The control of water quality in urban runoff is in its technical infancy. Never-the-less Water Quality Act of 1987 states that stormwater pollution must be reduced to the maximum extent...

Automatic Control of a Sewage Interceptor
This paper presents a control system for the automatic operation of a sewage intercepter with control gates to reduce sewage discharge to the receiving waters. One of the issues of the...

CSO Pollution Abatement Project Performance
The City of Trenton, NJ combined sewer overflow (CSO) pollution abatement project has been in operation for more than four years. Daily records include composite BOD5...

An Expert System for the Planning and Design of Flood Control Channels
The planning and design of flood control channels often calls for the evaluation of a unique set of physical conditions which do not lend themselves to standard designs. Consequently,...

Total Quality Management
Total Quality Management (TQM) is an organizational management approach that is receiving increasing attention in a wide variety of organizations, including the Ford Motor Company, General...

A Comparison of Accuracies of Steady Water Surface Profiles
The author compares the effect of varying boundary conditions and cross sectional spacing on one dimensional steady water surface profiles. Six streams are modeled using both the 10 and...

Unification in Estimation of Confidence Intervals
One area of future development needs in technology pertaining to surface runoff hydrology is the unification of techniques used by govermental agencies in the estimation of surface runoff...

The Hydrology of Urban Runoff Quality Management
Recent regulatory requirements to reduce pollutant discharges from municipal storm sewer systems have intensified the need for approaches to developing design parameters, such as the selection...
