ORMAN YANGINLARININ TOPRAK EROZYON RİSKİ ÜZERİNDEKİ ETKİLERİNİN ICONA MODELİ KULLANILARAK BELİRLENMESİ: AYVALI BARAJ HAVZASI ÖRNEĞİ

Soil erosion in dam watersheds is a crucial phenomenon since dams have become critical component of economic development for many countries. Therefore, the expected increase both forest fires and heavy rains Mediterranean region poses threat to watersheds. The these two phenomena will cause serious soil after revealing possible effects on risk be extremely beneficial taking proactive measures management So, goal this study reveal determine effect Ayvalı watershed. ICONA model was used area. determined by scenario analysis. In fire scenario, it assumed that all forests area are burned. Considering new map produced with model. Then maps were compared. results showed 70.33% faced very high risk, while 21.65%, 7.19%, 0.77%, 0.05% had high, medium, low, low respectively. This potentially from steep slopes, erodibility, sparse vegetation density As result areas increased 18.11%, decreased 48.55%, 26.36%, 35.43%, 100%, findings can guide decision-makers prioritize necessary precautions depending potential before fires.
