Real-time Animation of Construction Activities
As a result of 3-D computer modeling, the availability of geometric data in an electronic form makes possible the use of computers for purely construction activities in ways that were...

A Model for Construction Quality and Productivity
A set of necessary and sufficient conditions for construction quality is developed. Numerical simulations are then performed to evaluate the effectiveness of various quality improvement...

Visual Scheduling
This paper presents a look at new innovative way to provide project schedule. The primary target is in visual scheduling presentation techniques. The systems presented include a system...

An Integrated Project Control Model
This paper defines the scope of current project control activities and presents an overview of the tools used to control projects. Problems with current project control systems and the...

Expert Systems for Civil Engineers
Education
While the technology of expert systems can provide engineers with another approach to the development of computable models for civil engineering problems, it is not clear what a course...

The Uses of CADD in Hydropower Development
The hydropower community needs inexpensive methods to thoroughly and quickly analyze the siting of hydroelectric projects. Computer-aided design and drafting (CADD) and programs like HYSIZE...

Spreadsheet Applications for Hydropower Developers and Operators
This paper will examine the role of spreadsheet analysis in all aspects of hydropower development. The structure of the presentation will be first to briefly present an overview of the...

Enhancement of Walleye Spawning Habitat Through Flow Regulation
This paper present the results of a study focused on assessing the flow requirements for walleye spawning below a hydroelectric project. The results suggested that both the fishery resource...

The Simulation of Variable Release Temperatures from the Rock Creek-Cresta Project Using the USFWS Instream Temperature Model
Pacific Gas and Electric Company (PGandE) operates the Rock Creek-Cresta Project on the North Fork Feather River (NFFR) for hydroelectric generation under authority of Federal Energy Regulatory...

Glen Canyon Environmental Studies Resource Response Analysis
The primary objective of the Glen Canyon Environmental Studies is to determine how the resources of the Grand Canyon respond to the operations of Glen Canyon Dam. Two levels of analysis...

Bio-Economic Models for Measuring the Economic Effects of Hydropower on Anadromous Fish Populations in the Pacific Northwest
An empirical model is presented for predicting the net economic value of changes in recreational catch of salmon and steelhead in Oregon, Washington and Idaho associated with construction...

Simulation of the Stanislaus Project: Performance of the U.S. Fish and Wildlife Service Instream Temperature Model on a Complex System
The primary objective of the study was to characterize the temperature regime of the MFSR Middle Fork Stanislaus River and determine the effect of alternate release flows on stream temperature...

Systems Analysis for Fisheries Protection and Mitigation at Corps of Engineers Columbia River Dams
Pacific Northwest anadromous salmon and steelhead that migrate to and from the ocean are greatly affected by the numerous Columbia and Snake River dams they have to pass, first downstream...

Hydropower Simulation: An Overview
