The document discusses a catchment investigation in Saint Jean that aims to find natural flood management solutions through soil infiltration tests. These tests assess the soil's capacity to absorb water by measuring its permeability and absorption rates. The results will help evaluate flood risk and develop management strategies tailored to the soil characteristics, while also preserving biodiversity and habitats. Next steps involve recapping the findings, identifying trends, and planning for additional research.

3. Overview of Soil Infiltration Tests
1 Testing Procedure
The soil infiltration tests involve assessing the permeability and absorption capacity
of the soil within the catchment area.
2 Equipment Used
Specialized tools, such as infiltrometers and soil moisture meters, are utilized to
conduct accurate infiltration tests.
3 Data Collection
The process includes meticulous data collection to analyze the soil's behavior and its
impact on floodwater management.

4. Purpose of Soil Infiltration Tests
Capacity Assessment
The tests aim to determine the
maximum volume of water that can be
absorbed by the soil within the
catchment area.
Flood Risk Evaluation
Understanding the soil's capacity helps
in evaluating flood risk and developing
targeted management strategies.
