Extreme Precipitation Risk – Frequency and Magnitude Shift of Critical Rainfall Thresholds - İzmir Province - CRIZ-ERS

This repository contains the Extreme Precipitation Risk Assessment workflow adapted from the CLIMAAX Heavy Rainfall methodology. The workflow evaluates how critical rainfall thresholds shift in magnitude and frequency under future climate scenarios. The objective is to assess whether current impact-based rainfall thresholds (e.g., 100 mm in 24 hours) remain adequate under projected climate change conditions. The analysis integrates: EURO-CORDEX climate projections Intensity–Duration–Frequency (IDF) curves Historical baseline (1976–2005) Future horizons (2041–2070) Multiple RCP scenarios (RCP4.5, RCP8.5) Folder Structure Input Exposure Layers (data_izmir/) izmi_hospital.geojson izmir_school.geojson Results - (results_izmir/) RP_Aydin_threshold_100mm.tif Baseline return period map (1976–2005) for the 100 mm / 24h rainfall threshold.
