Northern Ireland, small and compact, geographically well defined with a relatively simple administrative structure, is able to establish a comprehensive Geographic Information System (GIS)...

Journal of Computing in Civil Engineering
The Journal of Computing in Civil Engineering serves as a resource to researchers, practitioners, and students on advances and innovative ideas in computing as applicable to the engineering profession....

Supervisory Control System Design
This paper presents supervisory control concepts, elements of a typical system, testing activities, project management, and the procurement process. Modes of control systems are discussed...

Maximum-Slew-Rate Nonlinear Control for Improved Transient Response in Hydrogenerators
This paper considers a linearized model for fixed blade turbines. This paper demonstrates that constant gate speed bang-bang control holds potential advantages over current control techniques....

Economical Computer Controls for Low Head Hydro
Small power systems based on renewable energy sources such as low head water falls, wind, solar and ocean tides all suffer from stochastic changes in input power. Economically viable,...

Planning for Hydro Projects in an Integrated System
The Incorporated County of Los Alamos, New Mexico (County) is forming an integrated electric utility system to serve the combined loads of the County and the Los Alamos National Laboratory...

Advances in Controls to Govern Mini and Micro Hydropower Systems
Conventional controls available for small hydropower systems are surveyed. Electronic load controls for micro hydropower systems are described. Recent developments in the literature are...

Mt. Tabor Hydroelectric Project
In 1980 the engineering staff of the City of Portland Bureau of Water Works identified several potential hydroelectric sites in Portland water supply and distribution system. The Mt. Tabor...

Design and Application of an Open-Loop Control System for Run of River Sites
This paper compares an open loop control system for variable geometry turbines to a closed loop system for fixed geometry turbines. The control systems were designed to operate three submersible...

Low Head Hydroelectric Development on Madera Canal
The Madera-Chowchilla Power Authority with cooperation from the U. S. Bureau of Reclamation has been successful in the development of four hydroelectric plants at five head drops on the...

North Fork Hydro Electric Power Station
