Testing has been conducted on new methods and storm data sources for the past two years with the purpose of providing more tools to dam owners for the assessment of probable maximum precipitation...
Improved HSPF Infiltration Calibration Procedure with a Linked GIS
A research project for the Florida Institute of Phosphate Research sought to develop an easy-to-apply integrated surface drainage model, HSPF, and groundwater model, MODFLOW, with a geographic...
Groundwater Modeling with GIS: An Example
The versatility and widespread usage of a geographic information system (GIS) as a hydrological modeling tool is only now showing up in the literature. In this regard, a research team...
A Three-Dimensional Natural Resource Damage Assessment and Coupled Geographical Information System
A numerical model for natural resource damage assessments is discussed. The model addresses a wide range of spatial and temporal scales. The transport equations for both pollutant and...
Application of a Geographic Information System to Estuarine Hydrodynamic Modeling
A geographic information system has been used in a hydrodynamic study of Albemarle Sound, North Carolina, to provide an efficient means for spatial data organization, information display,...
Data Acquisition for Hydrologic GIS
Various data acquisition options for hydrologic oriented GIS are presented. These options include manual digitizing, commercial digital data, satellite products, and automated scanning....
G.I.S. Applications in Nonpoint Source Pollution Assessment
A Geographic Information System (GIS) provides a flexible tool for developing the oftentimes cumbersome soils and land use mapping database required in watershed storm water management...
Geographic Information Systems in Water Resources Management
The management of surface and ground water resources within Southern California is increasingly difficult. As population expands, municipal demands for water are increasing. At the same...
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,...
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....
Reasoning for Data Integration
Improving the inter-disciplinary communication of design and construction data is an important objective in improving the competitiveness of our construction industry. This paper discusses...
The Virtual Design Team: An Object-Oriented Model of Information Sharing in Project Design Teams
The Virtual Design Team (VDT) is an object-oriented, discrete event simulation of a multidisciplinary design team in action. The VDT models a design task as a network of design and design...
