PC-based Geographic Information System (GIS) for Design and Management of Disposal Sites

Category:

Information Systems

Description:

Development of user-friendly, PC-based system that incorporates a relational database

management system and a Geographic Information System (GIS) for management and design of

offshore disposal sites. USACE New York District contracted Science Applications International

Corporation (SAIC) and Applied Science Associates (ASA) to develop Disposal Analysis

Network for New York District (DAN-NY).

During the spring of 1997, the NYD, WES, and SAIC were involved with the disposal and

capping of 700,000 yd3 of mildly contaminated dredged materials at the Mud Dump Site.

DAN-NY was used during the design phase to select the optimal disposal location, to test

candidate disposal scenarios, and to conduct multiple runs with MDFATE. Dredging, disposal,

and capping operations were conducted from May through October 1997. Throughout the project

DAN-NY proved to be valuable for:

1) Managing the placement of disposal marker buoys.

2) Monitoring the locations of individual disposal events.

3) Analysis of the near real-time data that were acquired from multiple bathymetric surveys of

mound topography.

WES is already in the process expanding elements of DAN-NY to design and manage other

offshore disposal sites at other USACE Districts.
