Risk Assessment of Sea Bottom Scouring Using Fuzzy Set Theory
An approach to the assessment of risk to buried pipelines from ice gouging is developed using Fuzzy Set Theory. Statistical procedures currently used to analyze ice gouge data are inadequate...

Quality Control Management of Real-Time Data
Recent improvements in the real-time acquisition of hydro-meteorological data have raised concerns regarding the quality of the data received. This paper presents several data verification...

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...

Watershed Management in 1985
Today's technology in subalpine watershed management is based on carefully designed watershed experiments beginning with Wagon Wheel Gap in 1909. Subsequent advances in process...

A Look to the Future in Watershed Management
The discipline of watershed management will continue as a viable specialized field as the scarcity, demand, and price of water increase in the future. Training of watershed managers should...

Santa Barbara Hydrograph with Green-Ampt Infiltration
Numerous models are available to estimate rainfall-induced runoff from watersheds. The leading criteria in model selection is often reproducibility. Models that are reproducible are often...

The Improved SCS TR-20 Network Watershed Model
SCS Technical Release 20, 'Computer Program for Project Formulation - Hydrology' (TR-20), has been revised. Major revisions include new procedures for hydrograph...

Evaluation of Runoff Prediction Using Synthetic Rainfall and CREAMS
Of all the climatological data, rainfall is the variable to which a watershed responds most significantly. The amount and sequence of occurrence of rainfall are most important in the prediction...

Urban Hydrology for Small Watersheds (Revised 1985)
Urban Hydrology for Small Watersheds, Technical Release 55, was first issued by the Soil Conservation Service in January 1975. It is a guide for SCS field personnel for estimating hydraulic...

Modeling Streamflow Response from Minnesota Peatlands
A deterministic, continuous simulation model was developed to predict the effects of peatland development on streamflow. The Peatland Hydrologic Impact Model is largely physically based...

Synthetic Unit Hydrographs for Ozark Watersheds
Few concepts in modern hydrology have been more widely used and abused than unit hydrograph theory. Nevertheless, during the years since its introduction in 1932 as an extension of the...

Assessing Risks of Impaired Hydrologic Function
This paper describes the rationale and use of a 'resource tolerance' to evaluate hydrologic function and presents a method to establish a relative tolerance threshold...

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...

The Role of Multiple Level Hydrologic Analysis in Watershed Management?A Case Study in Trinidad
An accurate estimation of peak flood flows and its correlation with existing and future land use are basic requirements for the scientific management of Watersheds. An accurate estimation...

Streamflow Generation from Subalpine Forests
Much of the hydrologic modelling done in the subalpine forest of the central Rockies is based on the Subalpine Water Balance Model. This paper reports on plot studies on the Fraser Experimental...

Snow Management at Ski Areas: Hydrologic Effects
Several types of snow management are practiced at downhill ski areas. Each of these activities has a variety of hydrologic consequences. The extent to which these management practices...

Interrelating Infiltration Measurements
Field measurements of infiltration rates are frequently used to index environmental conditions, soil hydrology, and the potential for rainstorm response. However, the variety of methods...

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...

Seepage Control for Embankment Dams USBR Practice
The current Bureau of Reclamation approach to seepage assessment, analysis, and design for embankment dams is described. The advantages and appropriate applications for the analysis programs...

Grout Penetrability
The ability of a grout to penetrate a formation is always a selection requirement for projects in which fracturing is undesirable. The major grout properties affecting penetrability are...
