Kendal Regency as Special Economic Zone and Industrial Park is stimulating the rapid coastal urban growth. This condition initiates the high risk of disaster in the northern Central Java. The research aims to model the tidal run-up and spatial inundation distribution using numerical calculation of logical tool-less than equal and to identify the land uses that are affected by the tidal run-up and inundation in the Kendal coastal area. This research conducted by the digital elevation model in 7 m spatial resolution and the highest high-water level (HHWL) data in the one-year analysis. Furthermore, the data processing was run using Less than equal tools. The result showed that the HHWL condition in 2018 reached up to 0.35 m. Considering the HHWL data, the eastern coastal area of the Kendal Regency is massively being affected by the tidal run-up and inundation. The furthest distance of the tidal run-up and inundation reached up to 3.7 km. There are six land uses affected, i.e., built-up area (0.04%), garden (2.01%), dry land (4.89%), grassland (5.09%), a fish pond (41.95%), and paddy field (4.24%).
