🌊 Flood Risk & Water Ponding Analysis

What is TWI? Topographic Wetness Index (TWI) is an index that measures how easily water accumulates in a location based on topography/terrain. The higher the TWI value, the greater the likelihood that the area will be flooded or waterlogged during rain.

Your Location Risk Status
📊 Regional Wetness Index (TWI)
24.10
Analysis Result: TWI Value 16.72, enhanced by Machine Learning for better accuracy 1.44x
🚨 Flood Risk Level
VERY HIGH
Meaning: This location has high flood risk. Immediate mitigation action is required.
🚨 Detected Flood Prone Areas

Our Machine Learning system found 3 zones zones potentially prone to flooding during heavy rain.
