Planning Model for Sewer System Rehabilitation
A probabilistic model is developed to simulate long-term variation in the structural condition of wastewater collection systems. The effects of both deterioration and rehabilitation can...
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...
Probabilistic Basis for Managing Maintenance
The paper discusses a procedure based on component failure probabilities, consequences of failure, and risk associated with loss of system. Aging effect of structures and equipment on...
Probabilistic Analysis of Maintenance Options
Maintenance usually means service disruption, repair cost and loss of production. This is especially true for structures or components which provide basic infrastructure services, such...
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 Newsboy Approach to Real-Time Reservoir Operation Modelling
This investigation focuses on the use of mathematical programming techniques to develop a model for scheduling, in real-time, the releases from a single reservoir via a probabilistic approach...
Applications of Probability Matrix Methods for Texas Reservoirs
Probability matrix methods are a class of procedures which were generally developed from P.A.P. Moran's Theory of Storage. In essence, probability matrix methods are a means...
Incorporating Risk Analysis Into Spreadsheet Forecasts
The risk analysis technique presented overcomes the difficulties of sensitivity analysis by entering key input variables as probability distributions, rather than as discreet values. Using...
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...
Optimizing Wet-Dry Precipitation Probabilities for Improving Plant Establishment
Studies have shown that the chances of achieving successful seedling establishment in arid and semiarid regions is dependent upon the pattern of favorable wet-dry precipitation sequences....
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...
Flood Hazard Delineation on Alluvial Fans
Alluvial fans are significant geomorphic features of arid lands. The unconfined and dynamic nature of alluvial fans makes standard methods of delineating flood hazards unsuitable. The...
