Coastal Erosion Modeling
Definition
Coastal Erosion Modeling in GIS involves simulating and analyzing the loss of coastal land due to wave action, sea level rise, and human activities. Models predict erosion rates, vulnerable zones, and potential infrastructure impacts.
Application
Used by coastal planners, environmental scientists, and disaster management agencies to assess risk, develop mitigation strategies, and support resilient infrastructure design in shoreline environments.
FAQ
What is the role of GIS in coastal erosion modeling?
GIS visualizes erosion patterns over time and supports predictive modeling using spatial datasets like shoreline position, tides, and wave energy.
What data is used for erosion modeling?
Satellite imagery, LiDAR, bathymetry, sea-level rise projections, and historical shoreline records are key inputs.
How does erosion modeling aid infrastructure planning?
It identifies at-risk areas, guiding setback zones, sea wall design, and early-warning systems for vulnerable developments.
Which tools are used for coastal erosion simulation?
Tools like DSAS (Digital Shoreline Analysis System), ArcGIS Spatial Analyst, and Delft3D are used for modeling coastal processes.
