Integrated Planning Analysis for an Aggregate Mine
Planning and design work of an aggregate mining facility within the Sutter Bypass, a key component of California's flood control system, is being performed by multidisciplinary team of...

Two Options for Disposal of Desalination Reject Water
A major problem associated with the use of desalination plants for the production of fresh water is the disposal of the reject water. This water is typically double the salinity of the...

Ballast Water Treatment Effluent Dispersion Studies
Treated tanker ballast water is discharged form Alyeska Pipeline Service Company's ballast water treatment facility through a multiport diffuser into Port Valdez, Alaska. The discharge...

Reliability Analysis of Levee System of a River
The levee height is determined by the summation between computed water level and an assumed freeboard. The water level is computed by given discharge in the steady conditions. Therefore,...

Mixing Character and Meandering Mechanism of a Plane Jet Bounded in a Shallow Water Layer
A plane jet in a shallow water layer is characterized by the jet width b₁/2 much larger than the water depth h at large downstream distances x/h...

Selective Withdrawal for Reducing Turbid Water in a Reservoir
This paper deals with improvemental operations of the selective withdrawal facilities as one of the comprehensive technics for shortening the turbid water stay after floods flown into...

Shifts in Solute Transport Direction Induced by Transient Flow
Traditionally, solute transport projections have focussed on the long-term, steady state conditions expected to prevail in a groundwater system. However, transient effects may often dominate...

A New In-Stream Aerator
Experiments on microporous, polymeric, hollow fiber membranes are being conducted for application to in-stream aeration. The hollow fibers are scaled on one end and connected to an oxygen...

Modeled Hydraulic and Salt Transport Patterns in the Sacramento-San Joaquin Delta
Modeled hydraulic and salt transport patterns in the Sacramento-San Joaquin Delta have been summarized as the basis for detailed environmental assessment of proposed water management projects...

Field Examination of a Distribution System Water Quality Model
In the aftermath of the Safe Drinking Water Act (SDWA) of 1974, numerous models have been established to assess the quality of water and simulate its deterioration in distribution systems....

River Engineering Flows and Some Related Structures (State of the Art)
The first part of the paper deals with a simplified overall review of water flows. Laminar versus turbulent, visualization of flow with unsteady 3-D manner and some typical hydraulic structures...

The EUR Water Station in Rome?Italy
The paper deals the new steel Water Centre realized by ACEA in Rome. The Water Station is destined to manage the water consumption of around 500,000 inhabitants with an output of 3,900...

A Culvert Analysis Program for Indirect Measurement of Discharge
A program based on the U.S. Geological Survey (USGS) methods for indirectly computing peak discharges through culverts allows users to employ input data formats used by the water surface...

Sediment and Water Quality Control Devices in Small Watersheds
The physical behavior and health of an alluvial stream depends on the extent of man's interferences in its tributary areas. In its natural setting a stream provides three main functions...

Vortex Spillway: Test Study on a Hydraulic Model
The paper deals with an experimental study on a model of the forced vortex of Eur hanging reservoir realized by ACEA (Rome). Some vortex characteristics are investigated and, in particularly,...

Variability in Solutions of Constrained Optimization Problems: Ocean Outfall Design Case
Uncertainty in optimization model resulting from parameter uncertainty has not been well studied in the hydraulics and water resources areas. To make valid decisions, knowledge of the...

Optimizing Water Transfers in Urban Water Supply Planning
A number of water supply agencies in the Western United States have begun to integrate water transfers into their overall water supply planning, including the use of transferred water...

Hydraulic and Water Quality Reliability and Resiliency for Water Distribution Systems Under Random Demands
This paper develops a preliminary method to evaluate the reliability and resiliency of water distribution systems under random spatial and temporal demand patterns, including random fire...

The Seattle Forecast Model: A Tool for Water Resources Management in the Seattle Area
The Seattle Forecast Model, SEAFM, developed by Hydrocomp Inc. for the Seattle Water Department, is an interactive, graphic system for streamflow forecasting and reservoir analysis of...

Modeling Vertical Stratification in the Pamlico River Estuary Using Modern Hydrodynamics
A modern hydrodynamic model is applied to the Pamlico River estuary. Good agreement was obtained between measured and predicted water elevations and salinity distributions during the one...
