Development of Modeling Subsystem in Comprehensive Rehabilitation DSS of Suzhou Creek

The comprehensive rehabilitation project of Suzhou Creek has been one of the largest water environmental rehabilitation projects in Shanghai. In order to assess the effect of the comprehensive rehabilitation project on water quality of Suzhou Creek, a DSS (decision supporting system) which includes a modeling subsystem, a GIS subsystem and a data analysis subsystem is developed and put into application. In this paper, the development of the core part of the comprehensive rehabilitation DSS of Suzhou Creek, namely the modeling subsystem, is introduced. The modeling subsystem comprises of hydrodynamic model, water quality model, interface between them, interfaces with database, DSS and users. VB 6.0 is chosen as the developing platform. The modeling subsystem is capable of creating project schemes, editing project schemes, project schemes computing, displaying results and analyzing project schemes, thus can support users on making decisions of rehabilitation project of Suzhou Creek.
