RCC in Dams in Australia
The design, construction and performance of the first three dams constructed in Australia, using RCC are described. Aspects covered in the paper include designing for zero cohesion between...
RCC Pavement Construction and Quality Control
In October 1986 a 16,500 sq yd (14,300 sq m) roller-compacted concrete (RCC) pavement tank hardstand, the first of its kind in Europe, was built for the U. S. Army at Harvey Barracks in...
Evaluation of Reservoir Seepage in Karst Topography
Areas where seepage is likely to occur in the karst environment of the proposed West County Reservoir, Roanoke County, Virginia have been indentified. Solutioning exists in the form of...
Flow Behavior of Kinked Strip Drains
Due to the often expressed concern over the axial deformation of strip drains and the resulting impact on flow rate, this study has been undertaken. A laboratory experiment has been constructed,...
Regulatory and Environmental Issues of the Chisman Creek Superfund Site
This paper discusses the regulatory and environmental issues arising from the response to the Record of Decision (ROD) for the Chisman Creek Superfund Site in York County, Virginia. Field...
First-Order Reliability Analysis of Groundwater Flow
A method for stochastic analysis of groundwater flow based on the first-order reliability approach is presented. The method is well suited for problems in which statistical information...
On Modelling the Nonlinear Relationship Between Random Fields by Means of Higher-Order Spectra
This paper addresses the input-output relationship of nonlinear systems that may be expressed in terms of a hierarchy of linear, quadratic and higher-order transfer functions or corresponding...
Pressures on Prisms in Turbulent Shear Flows
Experimental results are presented which show that Melbourne's 'Small Scale Spectral Density Parameter,' S, controls the negative pressures on the...
A Simple Nonpoint Source Groundwater Quality Management Model
A model is examined which efficiently produces information required by decision makers to assess water quality tradeoffs associated with alternative groundwater protection strategies,...
An Operations Advisor for Regional Water Management
The application of artificial intelligence techniques was evaluated for implementation for water control structure operations at the South Florida Water Management District. After an analysis...
Design of the Oasis Advisory System
Once the decision was made to develop an advisory system for the operation of water control structures within the South Florida Water Management District, a schedule of activities leading...
Assessing WQ Impacts Using a Hydraulic Model
Engineering projects may cause water quality impacts in estuarine systems. It is important to assess those impacts during the planning phase of the project so that mitigation measures...
Sanitary Sewer Model with Database Management
While numerous water supply and stormwater system models existed, the few sanitary sewer models that were readily available were too simplistic for engineering design and master planning...
Sanitary Sewer System Modeling for Operation and Planning
Development of a Steady State Sanitary Sewer Simulation (S5) computer model helped Newport News, Virginia, enact an efficient sanitary sewer management...
Water Quality Assessment and Management System in Regulatory Environments
State water quality regulatory agencies need to prioritize water bodies for program actions so that agency workload can be determined and resources allocated in order to achieve positive...
Spreadsheet Applications in Water Quality Management
The state regulatory environment requires simple, quick, easy to use and maintain water quality analysis tools. Therefore, for the evaluation of toxic substances, a new approach towards...
Conjunctive Use Study of Groundwater and Surface Water in Chino Basin, California
The purpose of this paper is to study the effects of artificial recharge on an already contaminated unconfined aquifer and propose optimal recharging and pumping schemes to prevent the...
Rehabilitation Strategies for Urban Drainage Systems?A European Perspective
Rehabilitation of urban drainage system is needed in many old European cities. This is in part due to the required structural upgrading of the existing sewerage system. But rehabilitation...
Optimal Pump Operation Using Nonlinear Programming
This paper focuses on the operational control problem of determining the optimal pump operation policy for a given distribution system. The optimal pump policy is defined as that schedule...
Regional Assessment of Pumpage in Southeastern Virginia
A U.S. Geological Survey investigation was conducted, in cooperation with the Virginia Water Control Board, to analyze the hydrogeology and groundwater flow system in the Coastal Plain...
