Simulation of Hillslope Hydrologic Response to Snowmelt in Southwestern Idaho
A two-dimensional, variably saturated porous media flow model was applied to vertical hillslope cross section on a first order study basin in southwestern Idaho. The dominant source of...
Soil Movement and Surface Roughness on Wyoming Rangelands
Soil movement and surface roughness parameters were evaluated as a function of response to livestock grazing and semiarid shrub control treatments. Repeated elevation measurements of erosion...
Characterization of Variable Soil-Water Properties
Hydraulic conductivity, water retention, soil bulk density, and clay content were analyzed on undisturbed soil cores obtained from different depths at sixteen locations in a 24 acre watershed....
Prediction of Soil Water Properties for Hydrologic Modeling
Water flow in soils can be characterized for many boundary and initial conditions by solving governing differential equations. Thus, a physically consistent means of quantifying water...
Closed Negotiations?Out with the Poker Players
The paper describes the closed negotiation process employed by one owner/client, the U. S. Army Corps of Engineers, in procuring firm, fixed price design service contracts. Although not...
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...
Avoiding Lengthy and Costly Litigation by Negotiating Alternative Dispute Resolution Methods
A 'hot issue' in the construction industry today is the negative aspects perceived from wide arbitration use over the last 15 years. Although hearings usually...
Advantages of Standard Contract Forms
The standard forms produced by the Engineer's Joint Contract Documents Committee (EJCDC) offer many advantages to Engineers and others involved in the negotiation and preparation...
Techniques of Negotiation
Three primary qualities are necessary for effective negotiation: knowledge, attitude, and skill. The author's firm has successfully used a negotiating team approach. This...
Embankment Seepage Control Design and Construction
For seepage control features of embankment dams, design criteria and construction practice is reviewed as it is reflected in the experience of the U. S. Army Corps of Engineers. The generally...
Seepage Control at Cochiti Dam, New Mexico
Significant design data, design assumptions and computations, and performance of the seepage control features provided at Cochiti Dam are summarized in this paper. The dam is a rolled...
Hydraulic Fracturing in Embankment Dams
There is now sufficient evidence to conclude that concentrated leaks occur commonly through the impervious sections of embankment dams by hydraulic fracturing without being observed, even...
Designing and Monitoring for Seepage at Calamus Dam
Given the complex, pervious nature of the foundation for Calamus Dam, every effort has been made to incorporate design features that will reduce and control the anticipated large volumes...
A Case History of Leakage from a Surface Impoundment
A manufacturing company constructed a 48-acre (19 hectare), unlined surface impoundment at a site in northern Texas to store wastewater. The site is underlain by unsaturated, alluvial...
Fracture Mechanics Analysis of Massive Hydraulic Fracturing Containment
The hydraulic fracturing containment problem is the subject of the present investigation. Unlike previous studies, the interface crack geometry with the correct crack tip singularity was...
Checking Off CADD Priorities
Diving head on into new computer aided design and drafting (CADD) hardware and software without considering their effects on firm or university's operation is as bad as ignoring...
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,...
Personal Computers and Stormwater Management Programs
Urban flooding and drainage problems are the result of complex interactions between natural and man-made systems. Comprehensive analysis of the hydrologic characteristics of these problems...
A Case Study - Toms River Water Company, Toms River, New Jersey
Toms River Water Company provides water service to Dover Township, the Borough of South Toms River and portions of Berkeley Township, all in Ocean County, New Jersey. Existing supply facilities...
Water System Model Brought Improvements in System Performance
Analysis of the hydraulic conditions of a multi-pressure zone water system serving portions of two counties in a mountainous region of Southwest Virginia was performed using computerized...
