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
1. 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.
2. What is the role of GIS in coastal erosion modeling?
Satellite imagery, LiDAR, bathymetry, sea-level rise projections, and historical shoreline records are key inputs.
3. What is the role of GIS in coastal erosion modeling?
It identifies at-risk areas, guiding setback zones, sea wall design, and early-warning systems for vulnerable developments.
4. What is the role of GIS in coastal erosion modeling?
Tools like DSAS (Digital Shoreline Analysis System), ArcGIS Spatial Analyst, and Delft3D are used for modeling coastal processes.
