Development of the Illinois Geographic Information System (GIS) from 1983 to the present is described including the hardware configuration and ARC/INFO software. The database design at...
Southwest Pass Training Structure Alternatives
The U.S. Army Engineer Waterways Experiment Station system of computer programs, TABS-2, was utilized to evaluate various structural plans for increasing channel velocities and sediment...
A Numerical Analysis Approach to the Solution of Unsteady Flow in Open Channels
Several inherent characteristics of all current numerical simulations of the unsteady flow equations prevent total confidence in their use. Inconsistencies within the numerical procedures...
A
A two-component turbulence model is introduced for depth-average flow calculations in shallow open-channel flows. This model treats the bed-generated turbulence as a background component,...
High-Resolution Two Dimensional Advective Transport
The paper describes a two-dimensional high-resolution scheme for advective transport that is based on a Eulerian-Lagrangian method with a flux limiter. The scheme is applied to the problem...
Far-Field Numerical Model Studies for Boston's New Secondary Treatment Plant Outfall Siting
By the late 1900s, Boston is scheduled to have built a new secondary treatment plant that combines the waste streams from two existing plant, and discharges the resulting liquid effluent...
UNET: A Model of Unsteady Flow Through a Full Network of Open Channels
UNET is a PC-based dynamic wave, unsteady flow model for the solution of the full network problem. The program applies a linearized implicit finite difference scheme to solve the full...
Channel Changes in the Platte River, 1926?1986
The Platte has changed significantly during the last century. A meandering channel with extensive riparian vegetation growth has replaced, the once braided and unvegetated channel in some...
Idealized Debris Flow in Flume with Bed Driven by a Conveyor Belt
The generalized viscoplastic fluid (GVF) model is used to derive the theoretical expressions of two-dimensional velocities and surface profile for debris flow established in a flume with...
Model for Determining the Optimal Rehabilitation and Replacement of Water Distribution System Pipes
K.E. Lansey and L.W. Mays developed a new methodology for the minimum cost design of new and expansion of existing water distribution systems. This methodology interfaces a nonlinear programming...
Important Aspects of Annual Energy Calculation Techniques for Low Head Hydro Power Plants
Annual energy calculations are frequently used to optimize design parameters at a turbine site and to compare energy production based on equipment offers from various suppliers. In this...
Simulations of Multireservoir System Operation
Simulation modeling has evolved from a direct examination of operating policies into operational decision support systems, integrated multiple use expansion planning systems and special...
Tunnels and Vertical Shafts for Pumped-Storage
Economic considerations are of primary importance to the planning and designing of pumped-storage in an electrical generation and distribution system. This paper deals with the optimum...
Design of Steel Tunnel Liners
The paper presents a detailed development of the fundamental equations for internal pressure design, considering an elastic interaction between the steel liner and the surrounding rock...
Freeboard Allowances for Chute Spillways
Allowances must be made for the physical phenomena which cannot be modelled, such as wave action, air bulking, splash and spray; the simplifications of behaviour implicit in the calculations;...
A Design Parameter Study of Turbine Draft Tube by Viscous Flow Analysis
Viscous flow analysis based on the full Reynolds-averaged Navier-Stokes equations is being applied to predict successfully turbulent flow characteristics and energy losses in different...
Moose River Air Chamber Design and Performance
The Moose River Hydroelectric Project is a 12.5 MW development located in upstate New York. It employs an underground air chamber to protect the unit and power tunnel from pressure surges...
HYOPS?Maximizing the Value of Your Hydro River System
This paper presents a microcomputer based software system, HYOPS, to optimize the operations of a series of hydro plants on a river system. The model can accommodate up to 10 plants which...
Instream Flow and Energy Production Studies for Hydro Relicensing
A methodology for assessing the effects of alternative flow release scenarios on both aquatic habitat and on energy production was utilized during instream flow studies at a 72-MW hydroelectric...
