Statistical Decision Analysis for Interception Wells
In this paper we apply the Bayesian decision analysis to the engineering design of a groundwater interception well whose purpose is to capture a contaminant plume. Two decision variables...
7-Day 10-Yr Low Flow Relationships for Ungauged Sites in Central Italy
The principal objective of the present study was to establish relationships between some easily measurable basin characteristics and seven-day ten-year Low Flow Index, Q7,10....
Ecuador?The Lower Guayas Flood Control and Drainage Project?A Case Study
The Government of Ecuador (GOE) invited the World Bank in 1975 for a general review of the rural development in the country. One of the main findings of a Bank mission was the importance...
Operation of the Tennessee Valley Authority Water Control System Under Extreme Drought Conditions
The Tennessee Valley region recently suffered through the most severe drought of record. As increasing demands were placed on the reservoir system, operating priorities were modified to...
Simulation of Runoff and Infiltration of Disturbed Land
Disturbances of land due to human and natural causes change the porosity and hydraulic conductivity of the soil. A simulation model of conjunctive surface-subsurface flows can be used...
Agricultural Impacts on Surface Water via Ground Water
Three years of ground and surface water quality monitoring data collected from one site in the mid-Atlantic coastal plain are presented. These data suggest that delivery of P from ground...
Expert System for Agricultural and Water Quality Management
Agricultural activities occur in an open environment where uncontrollable climatic events influence both agricultural productivity and water quality. A decision support system is described...
Gradual Development of Bores in Canal Systems
Modern computer programs for modeling unsteady flow in open channels are typically constructed using a momentum conserving form of the Saint Venant equations. This allows computation of...
Case Studies of Semi-Closed Pipeline Systems for Flexible Deliveries
The semi-closed pipeline system using the best aspects of the open and the closed pipeline systems, has many applications. It is the best adapted system for use with the variable flow...
Darcy-Weisbach Roughness Coefficients for Selected Residue Materials
A laboratory study is conducted to measure Darcy-Weisbach roughness coefficients for corn, cotton, peanut, pine needles, sorghum, soybeans, sunflower, and wheat residue. Varying rates...
Calculation of Runoff from Rainfall Using NURP Data
Peak runoff flows and flood hydrographs are important elements in the design of drainage and flood-protection structures. The validity of methods for predicting peak flow from rainfall...
ET from Shallow Groundwater Maintained by Controlled-Drainage/Subirrigation System
Soil-water management by maintaining a shallow groundwater level (watertable) via a dual purpose subdrainage-subirrigation system, is becoming popular in humid regions of the United States...
Modern Crane Control Enhancements
Terminal operators are continually looking for innovative ways to enhance the productivity and safety of their container cranes. This paper discusses examples of control enhancements that...
Honolulu Harbor Ship Traffic Simulation and Animation Study
A computer simulation and animation study was conducted to investigate the operational impacts of projected ship traffic increases and harbor reconfiguration specified in the Honolulu...
Perceptions, Sensitivity, and Solutions; Water Quality 2000
Commencing early in 1971, the Water Pollution Control Federation (WPCF) (now Water Environment Federation) established a series of challenge groups which would develop information essential...
Use of Interactive Simulation Environments for Evaluation of Water Supply Reliability
This paper investigates physical performance measures and their practical application to a regional water resource system for western Washington. Specific criteria for characterizing the...
Computer Support for Water Quality Management in San Diego Bay
At present, a variety of computer based systems and techniques, including mathematical models, data bases, information management schemes, statistical analysis packages, and graphical...
Estimating Urban and Suburban Sewage Flows with Assistance of GIS Technology
The Massachusetts Water Resource Authority (MWRA), an agency created by the Massachusetts legislature to provide wholesale water and sewer services to the metropolitan Boston areea, is...
Development of the San Fernando Basin Groundwater Flow Model
This paper describes the development and calibration of the San Fernando Basin (SFB) groundwater flow model. The SFB is the largest groundwater basin in the Upper Los Angeles River Area...
Optimization Model for Operation of Recharge Basins
A mathematical model is developed for the optimal operation of recharge basins, which is a non-linear optimization problem. The objective of the model is to determine the operation that...
