Hydraulics and Hydrology in the Small Computer Age
The theme of the 1985 ASCE Hydraulics Division Specialty Conference is ?Hydraulics and Hydrology in the Small Computer Age.? The goal of this conference is to demonstrate innovative hydraulic...
Hydraulic Design of the Strontia Springs Diversion Dam
The hydraulic features which were of primary significance for the project were the diversion tunnel and spillway. The low-level outlet valves and water-supply intake were relatively straight-forward...
In Situ State of Underwater Hydraulic Sand Fills
An approach is described for quantifying the in situ state of hydraulically placed sand fills which are a significant element in the construction of artificial exploration islands in the...
Method for Weakening the Ice Cover in Northern Rivers
The recent acceleration of development activities in the North, mainly related to the development of oil and gas fields, has necessitated the bridging of many arctic streams. In such streams,...
The Sand Mattress Method of Slope Protection
The sand mattress concept offers promise as an economical alternative to sand bag armor for two distinct applications: (1) slope protection for exploratory islands and/or causeway facilities,...
Asphalt Revetments for Slope Protection in the Arctic
Experience in the Netherlands demonstrates that slope protection of coastal embankments subjected to heavy wave action can be accomplished with lining systems made of mixtures of asphalt...
Geotechnical Design of Caisson Islands
There are a number of areas where fundamental geotechnical research is required so that non-conservative, rational and safe design of artificial exploration islands can be achieved. Some...
Dam Pioneers Concrete Variant
The Willow Creek Dam in Oregon is the nation's first dam made entirely of roller compacted concrete. The design and construction of this dam are described and special problems...
MILHY?A Microcomputer Based Hydrologic and Hydraulic Model
MILHY is an interactive, single event, lumped parameter model used to estimate streamflows and water surface profiles. The model was designed for use on basins less than approximately...
Methods for Reliability Analysis of Water Distribution Networks
A detailed review of the literature reveals that there is currently no universally accepted definition or measure of reliability for water distribution networks. The purpose of this paper...
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...
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...
