Cross Shore Variations in Heavy Minerals in Beaches of the Barrier Dominated Southeast Atlantic Coast
Cross shore beach sample sets from 102 locations along the barrier dominated Atlantic coast from Kitty Hawk, North Carolina, to Palm Beach, Florida were studied to determine if there were...
Global Risk Assessment: A Naive Look at Initiating Processes
Global risk assessment is finding those initiating processes which may cause harm to Earth systems (and ultimately the human species), their probability of occurrence, and the level of...
Water Quality Assessment in a Stochastic Stream Environment
Methodologies are presented within this article to aid in the quantification of the uncertainty in the management of stream water quality. Specifically, means are developed for: (1) establishing...
Surface Water Particles: Coagulation and Sorption
A size-dependent particle and particle-associated contaminant transport and fate model is presented. The unsteady, two-dimensional model couples the water column and bed and enables analysis...
The Water Erosion Prediction Project: Model Overview
A new generation of water erosion prediction technology is being developed by the USDA Water Erosion Prediction Project (WEPP). The WEPP models are a new erosion prediction technology...
Probabilistic Dependable Hydro Capacity: Benefits of Synthetic Hydrology
This paper focuses on the benefits of using synthetic streamflows (the 'synthetic hydrology' approach) for determining a probabilistically defined dependable...
Real-Time Hydrosystem Operations Using Probabilistic Balancing Rule Models
A Probabilistic Balancing Rule model is presented and shown to be effective in the prescription of real-time (daily) operations for a multi-purpose surface water reservoir system. In this...
Computer Control of Houston's Water System
The City of Houston's Central Surveillance and Control System utilizes dual host computers and over 100 'smart' Remote Terminal Units to control...
Bed Topography and Sorting in Alluvial Channel Bends
A quasi-three-dimensional model has been developed for the purpose of calculating the velocity distribution, the bed topography and sediment sorting along channel bends. The depth-averaged...
Baseflow and Beta Distribution
For water resources projects, design engineers are often required to separate total flow into baseflow and direct runoff. During such studies, baseflow is considered a crucial parameter;...
Groins and Vanes Developed Basing Upon a New Concept of Bank Protection
At curved bends, scour at the outer bank always accompanies deposition at the inner bank. A highly efficient river course for flood flow is considered to have a small lateral gradient...
Probability of Extreme Precipitation by Months
Daily rainfall records during the months of October through April at rainfall gaging stations near the Kings River drainage basin in the Sierra Nevada Mountains of central California were...
Probabilities of Hydrologic Extremes and Risk Analysis
Extreme floods of very low probabilities, e.g., 10-6 and 10-7, are estimated using data on annual flood peaks...
Joint Probability Calculation of Storm Depths
A methodology is presented to estimate exceedance probabilities of rainfall depths over large areas using joint probability. The joint probability estimate combines the frequency distribution...
Extreme Flood Probability Estimates in Practice
Selecting the safety design flood for a dam or siting structures where flooding would cause severe social or economic disruption requires balancing the likelihood and consequences of failure...
Effects of Runoff Changes and Sea Level Rise on Salinity in the Delaware River Estuary
The objective of this study is to investigate changes in the spatial distribution of salt in the Delaware Estuary resulting from climate induced changes in freshwater inflows and in the...
Estimation of the Probability of a Precipitation Event Occurring Over a Specified Watershed
A methodology is proposed for making rational flood control decisions when the physical characteristics of the upstream watershed are known and the characteristics of the extreme precipitation...
Technical Considerations in Numerical Modeling of Pressure Reducing Valves in Water Distribution Systems
In large water distribution networks, pressure reducing valves (PRVs) are common water appurtenances. However, there are difficulties in representing them when using the Hazen-Williams...
Model Study of New Madrid Pumping Station
The proposed pumping station on the New Madrid Floodway consisted of a draft tube type sump design (referred to as a formed suction inlet) to eliminate swirl and provide a more uniform...
Overfall Stress and Pressure Distributions
The magnitude and distribution of hydraulic shear stress and pressure on the boundary of a straight drop overfall are presented for multiple overfall heights and flow rates. Hydraulic...
