Abstract: The coastal area of Pekalongan, especially the estuary area of the Banger River, Loji River, and Gabus River, are often experiencing to tidal floods. Tidal Floods that occur pose a great risk due to the sedimentation of river mouths and floods from the watershed to the coastal area of Pekalongan. This study aims to assess the impact of climate change on flood frequency patterns and the contribution of each sub-watershed to the total discharge that occurs, as well as to analyze the effect of increasing sea level that occurs in the coastal area of Pekalongan. The method used in this research hydro-meteorological, hydraulic, and hydrodynamics two-dimensional analysis. The results showed that the climate change that occurred in the coastal area of Pekalongan was indicated by an increase in the average temperature of about 1o Celsius and the trend towards maximum yearly precipitationthat occurred during a period of twenty years had increased (2000-2019 period). An Increasing temperature that occurs has a significant risk to sea-level rise and increasing uncertainty hydrometeorological hazard (tidal flooding). Recommendations from this study are structuring the drainage system based on an integrated landscape arrangement concept to improve the economy, tourism, social, and environment to achieve sustainable coastal infrastructure.
