Risk Analysis of Fire-Affected Areas in the Cumbres de Monterrey National Park.
Objective:
To characterize the risk of sediment flow in areas affected by the 2021 wildfires in Cumbres de Monterrey National Park (PNCM). The goal is to identify areas with the highest likelihood and volume of sediment movement in order to prioritize restoration actions and sediment flow control.
Methodology:
The analysis is based on the USGS methodology for sediment flow characterization in fire-affected regions. Data includes Sentinel-2 satellite images, "Factor K" information, digital elevation models, and modeled storms. The process was conducted using QGIS and Google Earth Engine.
1. Probability of Sediment Flow Occurrence:
The probability of sediment flow was estimated at the sub-basin level, considering fire severity, terrain slope, and the "K Factor.".
2. Sediment Flow Volume:
The volume was calculated using an empirical model that predicts the amount of sediment deposited due to sediment flows, factoring in the affected area, slope, and accumulated rainfall.
3. Risk Classification:
Areas with the highest probability of risk and sediment volume were prioritized, and the risk was classified at different levels to guide restoration efforts.
Key Components:
• Fire Severity Analysis: Identification of areas affected with moderate-high and high severity.
• Sediment Flow Modeling: Estimation of the probability and volume of sediment flow in burned areas.
• Risk Classification: Prioritizing high-risk areas for restoration and control measures.
Project highlights:
1. High Sediment Flow Probability in Santiago: Most of the burned area in Santiago has a sediment flow probability greater than 80%.
2. Highest Sediment Volumes: Located in the southeast of Santiago’s affected area.
3. Critical Areas in Rayones/Montemorelos: Western areas have more than 80% sediment flow probability.
4. Risk Classification: Highest-risk sub-basins are in central-west Santiago and central Rayones/Montemorelos.
Users: The environmental sector, civil protection organizations, and local authorities responsible for risk management and restoration.
Impact:
The analysis identifies areas at highest risk for sediment flow, helping prioritize interventions to mitigate negative impacts on infrastructure and human settlements. The results are also key for designing soil restoration strategies and preventing future hydrological risks
