Land use changes and rainfall can trigger inundation. This study aimed to observe the dynamics of spatial patterns temporal flood vulnerability due land using Maximum Entropy (MaxEnt) Model. Flood was assessed 12 environmental variables, including elevation, slope gradient, direction, curvature, Topographic Wetness Index (TWI), flow density, distance from rivers, roads, soil texture, aggregates, rainfall, use. Rainfall were dynamic variables analyzed in 2013-2023. Past occurrence points obtained participatory mapping method. Temporal 2013, 2018, 2023 showed influence which very dominant. Typically, pattern formed a percentage moderate (13%), high (17%), (5%) class areas consistently clustered southern region. An interesting finding is that have more significant (7.2%), causing high-class patterns, compared (0.4%). MaxEnt's prediction accuracy classified as good, evidenced by its AUC values 0.835 0.819 0.824 2023. Finally, findings MaxEnt Model so it be extrapolated globally with similar regional typologies.
