Updating New York City's Sewer and Water Main Distribution Systems: Practical Applications of GIS
To systematically begin meeting infrastructure management challenges, the City of New York has dedicated precious resources to implement a utility-based Geographic Information System (GIS)....

Civil Engineering Applications of Remote Sensing London Docklands—A Case Study in Applied GIS
This paper addresses the role of remote sensing and Geographic Information System (GIS) technology in transforming the London Docklands from a run-down area of urban decline to a spectacular...

Municipal GIS Applications Utilizing Vector and Raster Software on Personal Computers
Confronted by increasingly tight budgetary constraints, combined with the expensive computer processing hardware typically required by a GIS, smaller engineering firms and local governments...

A GIS Based Geomorphic Approach for the Digital Computation of Time-Area Curves
Hydrologists routinely operate simulation models to approximate the runoff process. A popular strategy is the routing of a 'time-area' histogram. In addition, state-of-the-art hydrologic...

The Application of GIS Technology in Planning and Maintaining Distribution and Collection Systems
To date, the use of geographic information in the planning and maintenance of distribution and collection systems has been limited to AM/FM systems. However, the needs of engineers while...

A Perfect Base for a GIS: The Digital Orthophoto
A digital orthophoto is a rectified image with no relief displacement or radial distortion inherent in an aerial photo. One advantage of a digital orthophotography is that it can be used...

Creativity and Water Resources: Theory and Stimulation
An attempt was made to assess the evolution of the water resources field. First, the most significant scientific advancements in the field since 2000 BC until early 1900 AD were listed...

Application of GIS in Monitoring and Trouble Shooting of Water Distribution Systems
In this study, the suitability of Geographical Information System (GIS) to monitor water distribution systems is investigated. Although GIS applications are widespread, the use of GIS...

The Use of GIS in the Study of Water Resources
GIS is becoming an increasingly important tool to the water resource plannar and manager. However, in order to integrate GIS effectively into this field, current and future hydrologists...

Field Data-Gathering: Critical First Step for a GIS
Gathering data in the field is one of the first major tasks required for developing a geographic information system (GIS) or automated mapping/facilities management (AM/FM) system. This...

Singularity Elements for the p-Version of the FEM
Singularity elements have been widely researched and successfully used with the h-version for fracture mechanics problems. This paper gives the results of numerical experiments with conventional...

Biomechanics of Local Articular Incongruities
Abnormalities of intra-articular contact near sites of local surface incongruity are frequently associated with secondary osteoarthrosis. We here review a series of experimental and computational...
