Tidal flooding and coastal adaptation responses in Pekalongan City

Abstract

Over the past 10 years, the coastal region of Pekalongan City has experienced the phenomenon of tidal flooding and has almost submerged coastal areas almost daily. At present, tidal floods have submerged 51% of the total area of Pekalongan City with a maximum inundation height of 1.1 meters. As a result, there has been damage to the economic, social, and physical (infrastructure). Adaptation response from all parties involved is needed to reduce negative impacts. The writing of this manuscript aims to find out the phenomenon of tidal flooding and the government's adaptation response together with the community in the coastal area of Pekalongan City. Lots of research on this issue, but in this manuscript focus on structural and non-structural adaptation responses. Data collection techniques in the study of literature and documentation. The results of the study showed that the tidal flooding in the coastal area of Pekalongan City in addition to sea-level rise and topography, this condition was also exacerbated by the phenomenon of land subsidence which reached minus 30-50 cm. Non-structural adaptation response by establishing disaster response organizations and disaster prepared posts, while early warning systems and flood control infrastructure are forms of structural adaptation responses.

Instrumenting GIS as Smart City Tools to Identify the Impact of Tidal Flood Threat in the Coastal Zone of Pekalongan City

“…Pekalongan City, Central Java, is an urban area that often experiences floods and tidal disasters. The research predicted the increase of flood in this area could attain 36 cm in 2025 and 132 cm in 2050 [2], [3]. The latest study also identified that tidal flooding had enlarged yearly.…”

“…The latest study also identified that tidal flooding had enlarged yearly. In 2020 alone, the tidal flood coverage area was 783.99 hectares [4], while other research asserted that tidal floods had affected 50% of Pekalongan city [3].…”

Total Suspended Solid Concentration Dynamics and Distribution Based on Geospatial Models in Mojo River Estuary, Pemalang

“…The circulation pattern of the study area is governed by the impacts of surface currents driven by monsoon winds and the tidal effects and circulation masses as it flows (Pratama, 2019). The tides along the coast of Pekalongan waters are predominantly mixed tide prevailing diurnal tides (Maharlika et al, 2020). Tidal data obtained from the Geospatial Information Agency (BIG), 2022 iPASOET | Sea Level Monitoring (big.go.id), which is then processed using the admiralty method.…”

Social vulnerability toward tsunami hazard in the coastal area of Bayah Dome Geopark, in Lebak Regency, Banten Province

“…On the contrary, Cihara sub-district was the least number of population and the lowest level of vulnerability to the tsunami disaster with a population of 31,826 -33,174 people. The high population density illustrates the high probability of loss of life and property hence threatening the community's survival [18]. Very high population densities will be more vulnerable to tsunamis than areas with lower densities because they have a high potential for victims when a tsunami arrives [19].…”
