Abstract
A Holistic Approach to Watershed and Floodplain Management
Track: Water Resources
Author(s): Tony Dudley, Scott Edelman
The City of Charlotte, North Carolina, and Watershed Concepts are using a custom suite of GIS/Water resources programs called WISE (Watershed Information SystEm) to manage storm water infrastructure and floodplain management.
The WISE software utilizes Esri's MapObjects technology to allow for the storage and use of virtually unlimited size terrain data. Having seamless terrain data available for the engineers to use for stormwater and floodplain analysis is critical to the success of any project.
Watershed Concepts and the City of Charlotte, North Carolina, have developed a County-wide, seamless digital elevation model (DEM) and triangular irregular network (TIN). These DEMs and TINs will facility the automated hydrologic and hydraulic analysis as well as the automated floodplain mapping.
Terrain data is imported in multiple formats and levels of accuracy. Terrain "collections" are prioritized based the quality and accuracy of the data to create a multilayer terrain model. Prioritization of the data allows for greater flexibility when working with large watershed areas and differing data sources. For example, an engineer may opt to use local survey data, County-wide LIDAR data, and State-wide USGS DEM data in one terrain project for engineering and watershed studies. The WISE software seamlessly integrates virtually unlimited data sets of unlimited size.
