Impact of Coastal Flood on Building, Infrastructure, and Community Adaptation in Bukit Bestari Tanjungpinang

Abstract

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.

Contributed Indicators to Fluvial Flood Along River Basin in Urban Area of Indonesia

“…Coastal Floods in Indonesia include tidal floods, which is a phenomenon of increasing sea level that results in the inundation of tidal areas. Coastal flooding can also be caused by large storms that increase the water level and create high waves (Hanif et al 2021). Increased flooding in coastal areas will affect both urban and traditional settlements not only due to rising sea levels and climatic factors of the island but also due to population increase in coastal areas (Esteban et al 2011).…”

Pemodelan Sebaran Habitat Dugong Dugon Kawasan Pesisir Pulau Bintan Kepulauan Riau, Indonesia

“…Sebagian besar aktivitas sehari-hari dugong adalah mencari makan diperairan dangkal. Selain memiliki kehidupan sosial, dugong juga memiliki kebiasaan muncul ke permukaan air (surfacing), menggelinding (rolling), dan istirahat (resting Dinamika kawasan ekosistem pesisir perlu menjadi perhatian penting dalam berbagai tujuan, dan pemantauan kondisi ekosistem pesisir dengan pemanfaatan teknologi geospasial seperti penginderaan jauh, sistem informasi geografis yang dipadukan dengan spasial data sains seperti maximum entropy, ini sangat berguna dan penting dalam integrasi data geospasial untuk pengelolaan kawasan lindung serta konservasi habitat satwa liar (Hanif, et al 2021a(Hanif, et al , 2021b. Untuk menentukan sebaran sebaran dugong perlu dilakukan pengolahan data spasial karena terdapat berbagai indikator geografis dan lingkungan yang memberikan informasi spasial tematik mengenai hal tersebut.…”

Flood resilient scenario modelling (FReSMo): Dynamic assessment of climate‐induced effects on land use

“…exposes an exceptionally large underequipped and economically diffident population to prolong inundation, causing significant damage to the built infrastructure (Edmonds et al, 2020;Hanif et al, 2021).…”
