ENTERPRISE AI ANALYSIS
Artificial intelligence evaluation of nature based flood resilience in hilly terrain
This research explores how AI-driven models like Random Forest (RF) and Support Vector Regression (SVR) can optimize flood resilience using nature-based solutions (NBS) in hilly terrains. By analyzing laboratory data on slope, rainfall intensity, and time ratio for flexible and rigid vegetation, the study finds that RF models significantly outperform SVR, especially with flexible vegetation. Flexible vegetation demonstrates an 8% greater reduction in peak discharge due to enhanced surface resistance and infiltration. SHAP analysis highlights time ratio as the most influential factor, followed by rainfall intensity. The findings underscore the potential of AI in predicting hydrological phenomena and inform urban planners on implementing effective NBS for flood mitigation.

Methodology
The methodology employed AI models (RF and SVR) to predict peak discharge in hilly terrain using laboratory-scale data. Key input parameters included slope, rainfall intensity, and time ratio (T/Tc) for both flexible and rigid vegetation. Data was split into training (70%), testing (15%), and validation (15%). Model performance was assessed using RMSE, R², MAE, and further analyzed with SHAP, Monte Carlo simulation, and partial dependence plots.

| MAE (ml/s) | 0.158 | 2.98 |
Key Findings
Flexible vegetation significantly reduces peak discharge by 8% more than rigid vegetation due to higher infiltration and surface resistance. The Random Forest (RF) model demonstrated superior predictive accuracy (R² = 0.9809 for flexible, 0.9906 for rigid) compared to SVR. SHAP analysis revealed that the time ratio (T/Tc) had the greatest influence on peak discharge, with a SHAP range of ±25 for flexible and ±30 for rigid vegetation, followed by rainfall intensity.
8%
Greater Peak Discharge Reduction
Flexible vegetation provided an 8% greater reduction in peak discharge compared to rigid vegetation, attributed to its superior surface resistance and infiltration capabilities. This highlights its effectiveness as a nature-based solution in hilly terrains.
| Vegetation Type | Peak Discharge Reduction Mechanism | Overall Effectiveness |
|---|---|---|
| Flexible Vegetation | Higher infiltration, increased surface resistance, temporal buffering. | More successful in slowing runoff and reducing peak discharge. |
| Rigid Vegetation | Flow resistance from trunk part, limited infiltration. | Less effective in reducing peak discharge compared to flexible vegetation. |
AI-Driven NBS for Hilly Terrain Flood Resilience
The study successfully demonstrated the application of AI, specifically Random Forest models, to optimize nature-based solutions for flood resilience in hilly terrains. By accurately predicting peak discharge under varying conditions, AI provides a robust framework for adaptive flood management. This approach allows for the dynamic assessment of vegetation types, highlighting flexible vegetation's superior performance in mitigating flash floods.
Key Learnings:
- AI models enhance predictive accuracy for non-linear hydrological phenomena.
- Flexible vegetation offers greater adaptability and resistance to flow.
- Time ratio is a critical predictor for peak discharge in vegetated areas.
Implications
The findings advocate for the widespread adoption of AI-driven nature-based solutions, particularly flexible vegetation, in urban planning and flood risk management for hilly regions. This approach provides a cost-effective and sustainable alternative to traditional gray infrastructure, enhancing resilience against flash floods and supporting broader sustainability goals. Policymakers should integrate AI tools for better forecasting and adaptive management strategies.
