The predicted environmental and economic effects of partial chaparral conversion for increased water yield on an experimental watershed in the Prescott National Forest, Arizona, are examined...
Mass. Municipal Watershed Management?Case Study
Most of the estimated 200,000 acres of municipally-owned watershed land in Massachusetts currently suffers from a lack of wise, multiple-use forest management which has resulted in lost...
Silent Negotiations: Listen with Your Eyes
More than sixty per cent of all communication is non-verbal. The impact of body language during negotiations can be either positive or negative, depending on the negotiator's...
Probability Applied to Slope Design?Case Histories
A major problem encountered with the choice of an appropriate value for the design probability. Initial experience, obtained during open-pit investigation, suggested that slope geometry...
Noise and Air Blast from Construction Blasting
Noise generated by construction blasting differs from other construction noise because of its frequency content. The audible high frequency portion is accompanied by a non audible, lower...
Computers in a Planning Context: Another Reality
Over the past twenty years water resources planning has seen a great increase in the development of computer methods of analysis. This has transformed the way the hydrology, hydraulics,...
Quantifying Social and Environmental Objectives
Over the past decade, there have been great improvements in economic and multiobjective techniques for quantifying social and environmental objectives in water resources planning. Nevertheless,...
Water Develoment Models for Contemporary Planning
A methodology for evaluating water planning alternatives was developed and applied to the Nebraska Platte River. The methodology involved a micro-computer based screening model and a multi-objective...
An Economic and Financial Planning Model
A comprehensive computer model for generation planning has been developed and applied to several large-scale power sector master plans. A unique feature of this model is the concurrent...
Analysis of Reservoir Operations on the IBM-PC
The optimization of reservoir operations is a major economic concern. This paper contributes a computer software package, SPORO, written for the IBM-PC, for the stochastic optimization...
Practical Water Demand Forecasting
The authors describe their experience in designing, building, and applying a water demand forecasting model for the Denver metropolitan area. In the presence of incomplete and sometimes...
Micro-Computer Water Develoment Screening Models
A micro-computer screening model was developed to analyze the physical and economic efficiencies of a large number of alternative options associated with a given water development project....
Personnel Policies for Operations Management in the Computer Age
The human factor is an essential ingredient and the key element in successful computer applications for water resources or any other field. Engineers in general, and engineering managers...
A Modified RBC Design: Performance Evaluation
An RBC (rotating biological contactor) system was designed using Pall rings type 40, and tested under high organic surface conditions. Influent soluble BOD averaged at 55 mg/l, equivalent...
Resource Recovery Mass-Burning Incineration
The various types of incineration systems are discussed, and the technical and economic factors to be considered in developing a resource recovery project are examined....
Land Treatment of API Separator Sludge
An extensive research project was undertaken to establish design and operational guidelines for treatment of oily sludge using land treatment systems. Forty-five test plots were established...
Carcinogen Risk Assessment
The various approaches to assessing carcinogen risk are described and evaluated....
Structural Safety Studies
Structural engineers are most concerned with the safety aspect of structures. The primary objective of structural engineers is to produce structures which are satisfactory in meeting certain...
Drilled Piers and Caissons II
Drilled piers or caissons, also called drilled shafts or bored piles, have long been a very cost effective foundation solution for many soil profile and load situations. A distinct advantage...
Institutional Incentives and Disincentives for Water Recycling and Reuse in the United States
A complex set of legislative/regulatory, technological, water conservation, and economic factors operate to affect the degree of industrial wastewater reuse/recycle in the United States....
