Tampa Does It with Mirrors
As one of the nation's fastest growing cities, Tampa needed far more public works dollars. But the traditional source, the real estate tax, can no longer be relied on so heavily,...
How to Strengthen Client-Consultant Relationships
Effective use of a professional consultant is often diminished by poor management-staff communication. Consultants, because of their previous experience, may be able to provide input to...
Assessing Results Weather Modification Programs
There is a continuing need to assess the effectiveness of operational precipitation augmentation weather modification programs. These assessments can serve a variety of needs including:...
Santa Clara Valley Weather Modification Program
This report describes a significant advancement in the Santa Clara Valley Water District's knowledge and understanding of its weather modification (cloudseeding) program,...
Surface Runoff Water Quality from Contaminated Dredged Material Placed Upland
Bioassay and associated tests have been developed and are being refined to assist in the evaluation of the environmental impact of dredged material disposal alternatives. Simulated rainfall-surface...
High Sediment Concentrations Require High In-Channel/Supply of Sediment
Flows with high sediment concentrations (greater than 10 percent by weight) most commonly occur either as debris flows in steep channels throughout the world, or as hyperconcentrated flows...
Design Accuracy of Stormwater Detention Basins
While the stormwater detention basin is the most frequently used method for controlling runoff from developing areas in the United States, there appears to be no statement of the probable...
Outlet Hydraulics vs. Storage Requirements
In many cases developers must use a portion of their land for temporary detention of storm runoff in order to comply with local ordinances. A simple method is outlined which yields the...
Detention Pond Outlet Design for Pollution Control
Stormwater runoff detention ponds were originally developed for the control of flooding and the designs of the outlet control structure must be modified to obtain pollution control objectives....
Flood Travel Time
The effects of infiltration on the flood travel time are investigated. In flood prediction, the physical domain for flood cumulation is expressed by the period of time for water to travel...
CN Approach to Water Budgets for Small Watersheds
In some states, issuance of a surface mining permit is dependent upon an assessment of the current hydrologic baseline of the area to be mined and of the probable future impacts of mining...
Simple Hydrologic Modeling
Several simple models for estimating precipitation and evapotranspiration from a limited data base are discussed. Rainfall probabilities may be calculated from mean monthly rainfall. Depth-duration-frequencies...
Decreases in Runoff and Sediment Yield by Drainage
Runoff and sediment yield from three small agricultural watersheds were measured during four winter rainfall seasons. Following two rainfall seasons of data collection, a subsurface drainage...
Snowmelt Runoff Models for Water Supply Forecasting
Remote sensing is changing the approach in snowmelt runoff modelling. Instead of a simulated snow cover, the areal extent of the real snow cover can be periodically evaluated. Adaptation...
Forecasting for Management of Spring Runoff in the Columbia River System
The National Weather Service, Corps of Engineers, and Bonneville Power Administration are affiliated in the 'Columbia River Forecast Service' (CRFS) to more efficiently...
The SNOTEL Data Acquisition System Design, Operation, and Uses
The Soil Conservation Service (SCS), U. S. Department of Agriculture, coordinates measurement of the winter snowpack in the Rockies, Sierra Nevada, Cascades, and other major mountain ranges...
Water Supply Supplemented by Airport Storm Runoff
The quality of natural and induced storm water runoff from Oahu's Honolulu International Airport (HIA) and four outer island airports in Hawaii was evaluated for water supply...
Goals and Objectives in Design of Detention Outlets
Goals are the broad general purposes of the detention pond and its outlet works. A typical goal for a detention pond would be to help manage storm runoff so as to maintain historic conditions...
Management Planning for Survival and Growth
Essential factors in company growth are the identification of client needs and wants and recognition of the needs and constraints of the organization. Successes are generated by timely,...
Market Research and the Engineering Firm
In an age of volatile market changes and stiff competition, engineering firms need continuous market research, the author writes, leading to development of an effective marketing plan....
