Dredged‐Material Disposal System Capacity Expansion

Abstract

An ensemble of analytical tools is used to identify capacity expansion alternatives for the Delaware River dredged‐material disposal system. Characteristics of the river and riparian area are stored and analyzed with a geographic information system. Site attractiveness maps produced with these data yield an array of potential expansion sites. The least‐costly schedule for acquisition of these sites is identified with branch‐and‐bound enumeration. For the enumeration, the operation cost of alternative expansion plans is evaluated with a network‐flow programming model of the disposal system.
