Knowledge-Based Expert System Applications to Lateral Earth Support Structures
Knowledge-based expert systems (KBES) are computer programs, based on artificial intelligence (AI) techniques, designed to reach the level of performance of a human expert in some specialized...
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...
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,...
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...
Devil's Gate Multi-Use Project and Urban Water Resource
Not since Congress passed the 1902 Reclamation Act has there been an opportunity for a water resources project to make such an instrumental impact on the environment. Historically, damming...
Sediment Impediment to Boat Launching at Miller Park, City of Avon Lake, Ohio
In 1987 a boat launching facility was constructed at Miller Park, in the City of Avon Lake, Lorain County, Ohio (Figure 1). There have been problems with sediment buildup ever since it...
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...
Wetland Valuation Based Upon Multi-Purpose Performance Evaluation
Wetland protection and restoration have become a top priority in water management. A wide variety of benefits are ascribed to wetland protection, e.g., flood control, water quality improvement,...
Creativity and Water Resources: Theory and Stimulation
An attempt was made to assess the evolution of the water resources field. First, the most significant scientific advancements in the field since 2000 BC until early 1900 AD were listed...
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,...
Presentation of Case Study and Identification of Special Interest Groups
A typical example facing the National Park Service is presented that demonstrates the diversity in objectives associated with water resources decision making in an environmentally conscious...
Live Demonstration with Attendees Participation
An application of multi criterion decision making is demonstrated in an interactive environment with Conference participants attending this session. A common problem facing water resources...
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...
Field Investigation for Leachate Flow in a Landfill
Field investigation for leachate flow was done for the Fresh Kills landfill at Staten Island, New York. The leachate monitoring program included data collection from the field for a six...
A Control Method for On-Demand Operation of Open-Channel Flow
This paper proposes a control system for the automatic operation of an open channel having upstream and downstream gates. The main issue is the use of a discrete-time algorithm which computes,...
