A Knowledge-Based System for the Environmental Design of Waterways (ENDOW)
Knowledge-based software systems accept problem descriptions from users and apply logic in order to generate a solution or solution set. These systems function over very narrow problem...
A Knowledge Based System for Design of Localized Mechanical Mixing Systems
Knowledge-based systems, frequently referred to as expert systems, have been used in a variety of computer-based design applications. They are particularly suited to design processes where...
LISP or CLIPS: Selecting an Expert System Tool in Hydraulic Engineering
The transfer of Artificial Intelligence(AI) technology from the research laboratories to the scientific and engineering environments has been made possible by phenomenal advances in computer...
GIS Visualization Techniques in Surface Water Resource Planning
Geographic information system (GIS) computer graphic displays of surface water resource conditions provides a means for valuation-by-visualization (VBV) of alternate plans. GIS display...
Applications of GIS for Water Quality Modeling in Agricultural and Urban Watersheds
Two studies were conducted to integrate: 1) an agricultural nonpoint source pollution model, AGNPS, with Geographic Information System (GIS) databases, digital elevation model (DEM) data,...
Uncertainty Quantification in Water Distribution Parameter Estimation
Calibration for water distribution system model parameters is usually undertaken with a minimal amount of field measurements so additional pseudomeasurements are assumed. Both the actual...
Measurements to Calibrate Suspended Sediment Model for Adsorbed Contaminant Transport Study of North Fork Holston River, Virginia
A daily suspended sediment (SS) and mercury transport model was developed for a 25-mile reach of the North Fork Holston River below Saltville, Virginia. Daily streamflow measurements;...
Routing for Lake and Tidal Canal Drainage System
A routing method is presented for lake and tidal canal interconnected drainage system in coastal urban areas. Combing reservoir routing, channel routing, and discharge computation of the...
Management of Water Resources Distribution in Iran
On the basis of 45th principle of the Iranian Constitution, seawater as well as river waters, streams and any other natural course, whether surface or underground, also floods, wastewaters,...
An Engineering Analysis of Sedimentation in Tidal Inlets
The engineering comparative analysis of deposition and scour of noncohesive sediments in the neighborhood of bridges over tidal inlets is a unique problem which does not lend itself conveniently...
Effect of Manning's Roughness Coefficient in Simulating Flow Parameters in Natural Channels
Manning's roughness coefficients are presented for three of the oldest and largest irrigation canals in Egypt. The discharges ranges from 35 to 318 m3/s....
Fluvial Recharge of Sand Mining Pit
Accuracy in modeling fluvial processes becomes increasingly important as development occurs along waterways. The FLUVIAL-12 (1, 2) model is used to simulate the recharge of sand mining...
Safety Analysis of Handset Wood Slab Formworks
A reliability index is calculated for flexural strength of a handset wood slab formwork system. Load and resistance models are based on a survey of construction loads and wood test data...
Construction Accident Analysis: The Inductive Learning Approach
This paper presents the use of inductive learning in the analysis of construction accidents. It provides a brief description of ROUGH, an inductive system based on the theory of rough...
Project Controls for Denver International Airport
Managing a $2 billion dollar construction program requires a unique application of tried and true control systems and provides an opportunity to innovate new methods. The Program utilizes...
Project Controls on the Channel Tunnel Project
Establishing controls for a multi-facted, multi-billion dollar, privately financed, project which is run by two organisations created solely for that one project has been a major challenge....
