The Optimum Dimensions of Radiative Spines
Radiative pin fins (spines) are important in conjunction with heat rejection systems for space applications. In the design of radiators for space applications, spines possessing minimum...
Upgrading Hydraulic Infrastructure for Level One Redundancy
In the current paper a methodology is presented for upgrading any single source water distribution system in order to provide a level one system redundancy at a minimum cost. A level one...
Predicting Watermain Breakage Rates
Recent studies on water main breakage have shown significant spatial and temporal clustering in the breakage pattern. The methodology described in the paper provides the basis for a prediction...
Evaluation of Global Warming Impact on Soil Moisture and Water Runoff in Texas
In this paper a numerical evaluation of the variability of soil moisture and surface runoff due to global warming is carried out. An analytical model of the soil moisture balance based...
A 3D-Stereo Graphics Interface for Operational Great Lakes Forecasts
A system for real-time predictions of Great Lakes physics and transport characteristics is now being implemented. The full 3D nature of the predictions demands accurate, high speed computer...
Siting the New Boston Harbor Outfall: Near-Field Analysis
In the near-field analysis for Boston's proposed Deer Island outfall to Massachusetts Bay, multiple initial dilution calculations were applied to estimate the frequency distribution...
A Method for Estimating Peak Flows from Small Agricultural Watersheds
An attempt was made to develop a method for estimating peak runoff from agricultural watersheds by analyzing precipitation and runoff data, and incorporating the results into a procedure...
Water Erosion Prediction Project (WEPP) Watershed Model: Hydrologic and Erosion Calculations
The Water Erosion Prediction Project (WEPP) watershed model is a distributed continuous simulation model developed to compute the spatial and temporal distribution of erosion and deposition...
Morphology and Roughness in the Hydraulics of Large Bed Element Channels
The evolution of natural steep channels is a function of two factors in accordance with the principle of least action: flow distribution in the channel and terrain geomorphology. Large...
Precipitation Variability Effects on Modeled Soil Water Deficits
Effective management of forages in steep Appalachian pastures requires an understanding of hydrologic and microclimatic processes on the area. This study was conducted to determine the...
Flume Experiments on Debris Flow
With the different characteristics of grain motion in debris flow, three layers are vertically divided, i.e., viscous collision layer, inertial collision layer and suspension layer. Both...
Large Floods and Climate Change in the Southwestern United States
Floods can have a tremendous impact on water resources but their properties may fluctuate at frequencies that defy recognition in short-term instrumented records. Paleoflood deposits provide...
Waves in a Fluid Mud Layer Flowing Down an Incline
To model the dynamics of fluid mud, lava, or debris with a high concentration of cohesive clay particles, we consider a thin sheet of Bingham plastic fluid flowing down a slope. The Bingham...
Some Aspects of the Mechanism of Debris Flow
As the first step of the development of a general two-phase flow model for debris flows, a simple granular model, which is considered as a special case of the two-phase flow model, is...
Simulating Spatially Varied Thunderstorm Rainfall
Using data from two independent, relatively dense networks of raingages located in the vicinity of Tucson, Arizona, the spatial distribution of thunderstorm rainfall was determined as...
Design Cloudburst and Flash Flood Methodology for the Western Mojave Desert, California
A methodology was required for estimating flow in ungaged drainages. An analysis of floods in the western Mojave Desert showed that the largest events on basins below 1,500 meters MSL...
Western Surface Climate and Streamflow and the El Nino/Southern Oscillation
Climate variability has direct social and economic impacts the most direct of which occur through the hydrologic cylce. Of primary concern to society are the hydrologic extremes of floods...
Structural Control of Ground-Water Induced Debris Flows
A number of case studies have attributed debris flow initiation to the effect of elevated pore pressure from a bedrock ground-water source. Debris flows on slopes underlain by Precambrian...
Graphics Advances Aid Flood Engineers
In the last decade options have been suggested to the Log-Pearson III (LP3) computation for predicting design flood behavior in semi-arid conditions. Observations from an ongoing study...
Thermal Plumes from Staged Diffusers into a Uniform Quiescent Environment
The behavior of thermal plumes from staged multiport diffusers was investigated experimentally. The three-dimensional temperature distribution was measured by scanning thermistor rakes...
