DREDGEMAP™
DREDGEMAP is a framework of sediment-related models from ASA’s in-house modeling software suite that includes SSFATE™, SSDOSE™, and CAPModel™ (built by ASA in collaboration with the U.S. Army Corps of Engineers). DREDGEMAP predicts the transport, dispersion, settling and re-suspension of sediment released to the water column by dredging operations. All models are integrated with advanced GIS and data processing and analysis tools.
ASA’s models and services can be used to determine optimal operational parameters to satisfy regulatory requirements for suspended sediment, and to study the impacts of dredge disposal and capping activities. ASA also provides general hydrodynamic and sediment transport modeling services.
The Geographic Information System (GIS) embedded within DREDGEMAP provides a means to retrieve, manipulate and display geographic data sets, yielding access and visualization of geographic information. DREDGEMAP is fully compatible with ASA's widely used oil spill model, OILMAP; hydrodynamic model, HYDROMAP; and water quality model, WQMAP.
Environmental Data Products & Custom Data Preparation
Base Maps
DREDGEMAP models can be set up for operation anywhere in the world. A geographic location for DREDGEMAP may be of any size and resolution. Please contact us for details. ASA can immediately prepare coastlines for anywhere in the world from the CIA, Digital Chart of the World (DCW), or World Vector Shoreline (WVS) databases. In addition, geo-referenced raster maps may also be used. Alternatively, base maps may be digitized from fine scale charts, or imported from existing GIS applications.
GIS Data Layers
Locations of sensitive resources such as critical biological habitats, water intakes, industrial sites, and archaeological sites may be supplied in a GIS database. These data may already be available in ASA archives, or we can readily rather and provide this data on an individual basis. The user may view, edit and update this database using DREDGEMAP’s embedded GIS.
Hydrodynamic Data
Models of water movement in oceans, estuaries, lakes, and rivers represent a fundamental component of many environmental assessment problems. Such models provide the basis for physical transport of suspended sediments in the water. ASA maintains several hydrodynamic models.
DREDGEMAP model software is used in-house by ASA and is not available for commercial distribution.
