Direct Sizing of Small Stormwater Pump Stations
Pump stations are components of stormwater drainage systems that remove collected storm runoff from locations where drainage by gravity is not feasible. Usually pump stations will operate...

Effects of Ignoring Well Losses on the Specific Capacity Function
This paper combines these equations with the traditional step-drawdown equation to generate a more realistic relationship among discharge, specific capacity, and drawdown. Under both confined...

Risk-Based Planning and Management of Maintenance Dredging
The U.S. Army Corps of Engineers (Corps) Institute for Water Resources (IWR) is developing and applying a risk-based approach to address maintenance dredging cost, reliability, and budgetary...

Computer Optimization of a Groundwater Treatment Facility
A computer model has been developed to optimize the operation of a groundwater oil recovery treatment plant. The site consists of 24 pump and treat recovery wells which lead to a treatment...

An Appropriate Technology to Treat Domestic Sewage
Various alternative wastewater treatment systems (AWWTS) are outlined and attention is drawn to a low cost sustainable wastewater treatment system that has been functioning satisfactorily...

The Cost of Highway Bridge Scour in the State of Minnesota
Different states are faced with different conditions with respect to geology, topography, climate, native vegetation types, bridge ownership, and bridges management systems, which in turn...

Cost Effectiveness and Incremental Cost Analyses for Environmental Planning
The objective of this paper is to present an approach for evaluating alternative plans for environmental restoration and mitigation. After discussing problems that currently preclude the...

Rapid Slope Monitoring
Use of inexpensive coaxial cable rather than inclinometers has cut the cost of monitoring slope movement at seven potential landslide sites in California. The method involved is called...

Boston Blockbuster
The Central Artery/Tunnel project in Boston is probably the single largest publicly-funded transportation project in the country at present. The total cost will be between $8 and $10 billion...

Underground Contracts for the 21st Century
Noting that support for the guidelines for underground construction put forth by ASCE's Underground Technology Council has been eroding, the author addresses current issues...

Budgets
Marketing budgets vary greatly from company to company. They will be much larger, when you calculate labor as a percentage of total marketing costs, for smaller firms than larger ones....
