Optimization, Simulation and Multiobjective Analysis of Operating Rules for Reservoir Systems
In this paper, three steps are proposed for establishing reservoir operating rules which can be used in real-time without flow forecasting. In the first step, optimization models are used...
Water Resources Systems Planning: Differential Dynamic Programming Models
A Monte Carlo optimization methodology is presented for water resources systems. The planning model define the optimal storage and release policies for the reservoir system. The optimization...
Air-Water Oxygen Transfer at Spillways and Hydraulic Jumps
Dissolved oxygen measurements are reported for seven spillway structures in the vicinity of Minneapolis, Minnesota, corresponding to 27 individual surveys. The surveys are taken during...
Gas Transfer and Secondary Currents in Open Channels
Laboratory flume experiments on water-wide controlled gas transfer, such as reaeration, are described. The experiments indicate that gas transfer is a surface renewal process, well described...
Chlorination of Wastewater Treated by Overland Flow
Results are presented from an investigation of the efficiency of three chlorination schemes used for the disinfection of municipal wastewater treated by overland flow. In experimental...
Water Erosion from Irrigation?An Overview
Erosion and sedimentation by water includes the process of detachment, movement, and deposition of soil particles (14). Under irrigated conditions, the erosive process is water flowing...
The Effect of Storms on Pollution Loading Estimates
A rather extensive field and modeling program is underway in the Sandusky Bay/Nearshore region of Lake Erie and the objective of this paper is to summarize the preliminary results of a...
Reservoir System Simulation Through Network Flow Programming
A generalized reservoir system simulation model that makes use of a network flow programming technique has been developed for use in planning and operation studies of multi-purpose water...
Storm Dynamics in the Lake Ontario Region
A program package, RAINPAK, was written to develop appropriate rainfall input, based on concepts of the physical processes behind the temporal and spatial distribution of storm rainfall...
Assessment of Drought Restriction Needs in New Jersey
Due to insufficient rainfall and related runoff during the spring of 1985, the Passaic and Hackensack River Basins in northern New Jersey and related storage reservoirs therein were able...
Classification and Behavior of Meander Migration
Meander migrations on the Mississippi River between Cairo, Illinois and Baton Rouge, Louisiana for the time period between the years 1765 and 1930 were classified into six categories based...
Management Strategy
Meanders of sinuous streams are often cut off by natural action or by man in order to improve conveyance or navigability. Cutoff bendways, as long as they remain aquatic, provide extremely...
Effect of the Fluid Velocity on the Biofilm Development
In order to get basic information concerning the application of a biological treatment to the ammonia nitrogen removal from drinking water, we considered the relation between the biofilm...
Grand Canyon Water Line by Directional Drilling
The South Rim Village at Grand Canyon National Park obtains its water supply from a point called Roaring Springs which is located approximately 15 miles across the Canyon on the North...
A Computer Model for Oil Slick Transport in Rivers
A computer model for simulating oil slick transport in rivers is presented. In the model the effects of advection, spreading, evaporation, and dissolution on the transformation of an oil...
In-Situ Microocosms for Calibrating Dynamic Models
The calibration of dynamic water quality models for lakes and reservoirs requires significant quantities of data, experience, and judgement. In particular, the identification of an appropriate...
Use of Stochastic Hydrology in Reservoir Operation
The Bureau of Reclamation is incorporating stochastic traces to provide a broader basis for management decisions during drought periods for the Central Valley Project in California. A...
Development of Two- and Three-Dimensional Modeling Systems for Open Channel Flow and Sedimentation
Two- and three-dimensional numerical modeling systems have been developed to address questions of open channel flow and sedimentation for the Corps of Engineers. These systems are complete,...
Physical Habitat Simulation and the Moveable Bed
One objective of an instream flow analysis is to quantify a flow that will maintain the existing channel and/or flush fine material from the bed. Five empirical approaches to determine...
Analysis of Freshwater Distribution System at the Long Beach Naval Complex
This account of the evaluation of freshwater pipelines at California's Long Beach Naval Complex discusses current methods for assessing the condition of damaged water lines....
