North Java, Indonesia's Shoreline degradation has become a severe problem along its coast. The gradually vanishing of the mangrove greenbelt indicates starting of coastal erosion. To overcome that problem, the adaptive concept using Building with Nature (BwN) is expected to become a part of the solution by enhancing the natural process. Construction of permeable structures was started in 2013. Its implementation was modeled using Delft3D. A coupling between Delft3DFlow and Delft3DWave is proposed. The model is conducted in two scenarios, coastal areas without and with permeable structures. Both were simulated in wet and dry seasons. It is analyzed on three years morphological scale. 10 observation points were determined in the front and back of structures. Those are utilized as control points to check the height of sediment trapped. Accumulation of sediment trapped in wet and dry seasons, and the coverage area was a dry season without structures. By adding a permeable structure, the maximum amount of sediment trapped in the wet season reaches 1.52 m in three years of simulation. It can be concluded that permeable structures constructed along the coast can trap the sediment. The placement, length, and number of structures should be considered to produce a wider coverage area. In the future, the sustainability of this adaptive concept is expected to enhance the coastal restoration in Demak coastal area.

“…Research conducted by [8] counted the area flooded due to extensive tidal floods in 2019, around 2400 hectares flooded with a range of inundation height of 1-66 cm. While research [27] predicted the potential tidal flooded area in Semarang by 2031 would be 8.2 % (3059 ha) of the total area of the city, 60.6 % of which would be developed areas. The area consists of industrial parks, 17.8 %; residential area, 11.2 %; trade and services, 15.7 %; public station area, 9.9 %; and others, 6.1 %.…”

Tidal floods and land subsidence often occur in the coastal areas of Semarang, Central Java. The coastal area of Semarang has an essential role in the economy of the city of Semarang, especially the Port of Tanjung Emas. Research with a multidisciplinary approach is expected to obtain conclusions on technical and non-technical problems to prepare mitigation measures and reduce the risk of tidal flooding. This study aims to determine and analyze the impact of tidal flooding in the city of Semarang using a multidisciplinary approach. The data used for the analysis came from literature studies and field observations. This research method is descriptive analysis. The results showed that the tidal flood caused damage to infrastructure, houses, and other public facilities. This damage makes the infrastructure not function optimally. Other impacts the community feels are disruption of economic activities, lower productivity, and increased maintenance costs, thereby reducing overall community income. Therefore, tidal flood prevention is needed from all stakeholders, both individually and collectively.

“…However, the relationship between urbanization and ood events does not always have a direct impact. Urbanization can reduce ood damage in some developed countries after various structural or non-structural measures for ood prevention are introduced (Asdak et al 2018; Buchori et al 2020). With rapid population growth, urbanization in developing countries, especially the development of physical space and changes in land use, is not well planned.…”

“…( Rapid urbanization coupled with a lack of land use planning will increase the amount of land affected by ooding (Hodgkins et al 2019; Waghwala and Agnihotri 2019; Chen et al 2021; Xing et al 2021;Villarrealrosas et al 2022). For example, the population of Dhaka in Bangladesh, Rio de Janeiro in Brazil, Lagos in Nigeria, and Jakarta in Indonesia are fast-growing cities in developing countries that increase vulnerability to ooding and decrease adaptive capacity to cope with oods (Bodoque et al 2016; Waghwala and Agnihotri 2019; Buchori et al 2020). However, the relationship between urbanization and ood events does not always have a direct impact.…”

This paper re-examines the facts of the influence of urban development that developed in Java on the occurrence of floods that started from 1970 to 2020. The purpose of this paper is to prove whether development policies in Indonesia in the last 50 years and to analyze the correlation between flood event, population growth, and urbanization on a wider regional scale. The Moran-I Spatial Autocorrelation Analysis method is applied to simulate the spatial pattern of flood events with combined results from satellite image interpretation with Spatial-temporal analysis from the 1970s to the 2020s. In more detail, the results of hotspot clusters show development from "lower-low" dispersion in the 70s to areas with a majority of "higher-high" clustered in 2000-2020. It proves that the burden of development in Java is in high category impact, so solutions for population distribution, land development, and spatial planning are needed to ensure environmental sustainability in Java.
