“…By referring to the value of losses, it is necessary to carefully consider the management of coastal areas in an effort to mitigate coastal flood disasters [12]. However, the coastal flood disaster conditions may become more severe in the future due to the contribution of global warming which causes an increase in sea surface height [14], and weather anomalies resulting in various hydrometeorological disasters in coastal areas [3,4].…”

“…The city is profoundly influenced by the dynamics of tidal flood or in Indonesia namely as (Banjir rob), which have a substantial impact on coastal residential areas. Coastal flooding is a primary concern due to its potential negative effects on society, the economy, and the environment [3]. Coastal regions are inherently dynamic environments, constantly undergoing physical changes.…”

Batam City, strategically located as an economic and industrial center in the Riau Islands province, Indonesia, faces challenges stemming from rising sea levels due to climate change and unusual tidal patterns. These factors lead to recurrent coastal flooding and create new issues for coastal areas. This research project has three primary objectives: tidal forecasting, tidal flood hazard mapping, and vulnerability assessment of infrastructure and settlements in Batam City's coastal areas. To achieve these goals, a combination of methods is employed. Tidal forecasts rely on a semimean linear trend approach. Spatial flood analysis considers the Hloss scenario, with the loss distance referring to the peak of the sea flood. Additionally, losses resulting from coastal flooding disasters were assessed using the Economic Commission for Latin America and the Caribbean (ECLAC) budget base planning (RAB) method. The research results reveal that the Batam area experiences two semidiurnal tides with dynamic sea level fluctuations, reaching a peak flood height of 2 meters. Spatial analysis identified several areas affected by tidal flooding, particularly densely populated coastal areas such as Batuaji, Batuampar, Sekupang, and Bengkong subdistricts. These areas, characterized by tidal flats, are particularly vulnerable to significant coastal flooding during high tide. The impact extends to key infrastructure, including roads, mosques, housing, and social facilities, resulting in estimated losses. The number of buildings affected by flood on Batam City is 12,681 units, and the flood affected area covers approximately 10,975.76 hectares, with road infrastructure costs amounting to about US$337,131.36. Field investigations also reveal that several settlements in the region have initiated flood protection measures. However, many settlements are still directly affected, underscoring the immediate need to improve environmental quality in this area.

“…Increased sea levels will affect people's lives on the shoreline because this area is affected by tidal activities. One of the disasters caused by a sudden rise in sea level is tidal flooding (Nofrizal, 2019). Tidal floods are different from ordinary floods, especially in the cause of the flood.…”

Coastal flood in Indonesia, namely as banjir rob, is a phenomenon that increases seawater to inundate around the tidal area. In Tanjungpinang, cases of coastal floods become a serious problem for people living in this area. This research aims to model the coastal flood inundation by modeling water inundation with a maximum level increase scenario. Its model was used to estimate coastal floods' impact on houses, buildings, and infrastructures with scenario 2 meters of sea-level rise. On the other hand, the budget loss for restoration was estimated to study the effort of community adaptations with the ECLAC RAB method and observation to understand community adaptation. It was found that the spatial model succeeded in zoning inundation areas, which had a significant impact on houses, buildings, worship places, schools, and industrial at many 4112 units. From this case, the budget loss for the restoration of the physical environment was estimated at around 61994014.75 USD. In addition, the survey revealed the existing condition before and after the coastal flood. Several community efforts for adaptation were developing houses on stilt and hoarding the lowest land on-site location for build houses.
