DYCAM: A Computer Aided Engineering Tool for Space Construction Planning
Planning and management of construction activities in space have not received sufficient attention up to the present. Space Station Freedom, a number of large platforms and extraterrestrial...
Alternatives for the U.S. Manned Space Program
There are a number of directions the U.S. space program could take. Should a space station be built? Should a lunar outpost be constructed? Should the U.S. plan a manned trip to Mars?...
The Use of Submersible ROVs for the Inspection and Repair of Water Conveyance Tunnels
At Virginia Power's Bath County Pumped Storage Station, robotic technology was pioneered through the development of a purpose-built Remotely Operated Vehicle (ROV) to gain...
A Methodology for Optimal Control of Pump Stations
Pumping water to utility customers is an expensive service which consumes large amounts of energy. Most approaches to date require simplifications and assumptions for the specific system...
Review of the Design, Construction, and Operation of the Lake Carolyn Flood Control Pump Station
A review of the design, construction, and initial operation of the Lake Carolyn Flood Control Pump Station in Irving, Texas is presented. Staged water resource development design concepts...
Development of an Optimization Model for Groundwater Withdrawal
An optimization model has been developed to simulate optimal values of withdrawal from a given aquifer system. The linear programming technique has been used to formulate the objective...
CTA's Experience in Fostering Station Redevelopment Through Public/Private Partnerships
The paper reviews the experience of the Chicago Transit Authority's partnerships with the private sector. The funding, space, design, construction and operation components...
Public/Private Partnership for Development of the South Brunswick Station
Because of projections for continued residential and commercial growth and a large gap between stations, NJ TRANSIT decided to construct a new station in the Township of South Brunswick....
Allied Junction/Secaucus Transfer Station?A Private/Public Partnership
This paper describes the background behind the development of the Allied Junction/Secaucus Transfer Station project, the improvements to the New Jersey TRANSIT rail network in Northern...
Management of Groundwater Overdraft in the Phoenix, Arizona, Area
By law, the overdrafting of groundwater in the Phoenix, Arizona, area must cease by the year 2025. Safe yield can be achieved by means of conservation, water supply augmentation, and condemnation...
Upgrading of the Orange Cove Irrigation District Water Distribution System
The Orange Cove Irrigation District covers about 28,000 Acres in the Central Valley of California. It is supplied from the Friant-Kern Canal. A semi-closed low pressure pipeline system...
Measurement of Irrigation Water Use: Results of Two Case Studies in Illinois
Three methods of measuring and estimating irrigation pumpage were used during two research studies attempting to assess ground-water use. These three methods: (1) farmer estimates; (2)...
Efficiency Testing of Water Wells
In the operation of a water well, the difference between the water level in the well before pumping starts and after it has been pumping for a period of time is termed 'drawdown.'...
Rehabilitation of Water Wells
The main causes of declining well yield are biological growths, mechanical clogging and chemical encrustation. Because the treatment of the causes of encrustation and clogging is expensive...
