| Issue: |
Landslides are a geological hazard across Indiana, notably exacerbated by the lack of comprehensive data on their occurrence and impacts. This gap significantly impedes effective risk management and mitigation planning. |
| Objective: |
Map and inventory landslides in Louisville, Madison, Greensburg, Cincinnati, Falmouth 100,000 scale quadrangles. |
| Approach: |
The project involves segmenting 1:100,000 scale quadrangles into 2,400 scale quadrangles, further divided into 252 grid squares of 0.607 square kilometers each. Each square will be analyzed using QL2 LiDAR and hillshade imagery at a 1:4,000 scale. Identified landslides will be mapped as polygons, containing detailed attributes such as movement records, slope details, and corrective measures, in accordance with Indiana Geological and Water Survey standards.
A field investigation will focus on verifying landslides on state-owned lands, including various State Parks, where signs of landslide activity such as crowns, scarps, and terrain irregularities will be recorded. This study aims to determine the impact of landslides on state infrastructure. Photographic evidence from these sites will be documented and shared via the IGWS digital collection database, along with GIS data incorporating detailed field observations. |
| Products: |
- Compilation of digital landslide photos and field notes.
- Integration of landslide GIS data into the Indiana Geological and Water Survey’s GIS inventory. |
| Benefits: |
- Enhanced accessibility to comprehensive landslide data for stakeholders, facilitating informed decision-making and risk management efforts.
- Improved understanding of landslide occurrences and characteristics, aiding in the development of effective mitigation strategies and emergency response plans.
- Increased public awareness and engagement regarding landslide hazards and their implications for safety and infrastructure resilience. |
