Abstract

Pekalongan City consistently experiences annual floods. In this research, we aimed to map the distribution of potential flood inundation in Pekalongan City under two scenarios: the existing land cover and urban planning (Rencana Tata Ruang Wilayah/RTRW). We utilized hydrological modeling to assess the suitability of the RTRW for future implementation. The Soil Conservation Service – Curve Number (SCS-CN) method was employed, incorporating Digital Elevation Model (DEM) data, soil data, precipitation data, and two sets of land cover data (existing and urban planning). The findings indicate that under the existing land cover, approximately 13.97% of the area is susceptible to flooding, while the remaining 86.03% is not at risk. Conversely, the model using the urban planning (RTRW) scenario suggests that 14.06% of the area has the potential to flood, while 85.94% is not susceptible to flooding. The increase in potential flooding in the urban planning scenario may be attributed to the expansion of residential areas and the reduction of plantation and dry land cover. Furthermore, in assessing monthly modeling results, we observed that the area with flood potential is highest in December 2022 and lowest in June 2022. Considering topographical conditions (DEM), we found that the potential for flood inundation is fairly and evenly distributed in flat areas, mostly with elevations of less than 11 meters. Areas at higher elevations are predominantly free from flood potential, but it is noteworthy that certain areas in the Pekalongan Selatan District, with elevations higher than 11 meters, still have the potential for flooding.  Keywords: Flood, hydrology model, SCS-CN, existing land cover, urban planning

Abstract

Teknologi Terrestrial Laser Scanning (TLS) dapat menghasilkan pemodelan 3-Dimensi dengan geometri yang baik. Namun, untuk dapat menghasilkan ketelitian geometri yang baik diperlukan teknik registrasi dan proses georeferensi yang tepat. Teknik registrasi yang banyak digunakan adalah menggunakan algoritma Iterative Closest Point (ICP). Keberhasilan teknik registrasi ini dipengaruhi oleh presentase overlap, besarnya sudut dan jarak antar dua data point clouds. Pada teknik georeferensi tidak langsung, data point clouds yang dihasilkan belum semuanya memiliki koordinat global sehingga untuk menyatukan semua hasil pemindaian, maka metode registrasi dilakukan dengan menggunakan registrasi target-to-target atau registrasi cloud-to-cloud perlu dilakukan sebelum menggunakan algoritma ICP. Pada teknik georeferensi langsung, data point clouds untuk seluruh hasil pemindaian sudah memiliki hasil koordinat global sehingga teknik registrasi yang digunakan bisa langsung menggunakan algoritma ICP. Hasil yang diperoleh adalah nilai Root Mean Square Error (RMS) adalah sama untuk kedua metode georeferensi langsung maupun georeferensi tidak langsung. Kata kunci: target-to-target, cloud-to-cloud, Iterative Closest Point (ICP)

Abstract

Abstract The coastal areas of Pekalongan City face a significant threat due to flooding and tidal surges. The low, flat topography complicates the management of drainage systems, given the relatively gentle land slope. Flooding incidents frequently occur in various parts of Pekalongan City. Furthermore, the global rise in sea levels and land subsidence in the region exacerbate this issue. This study aims to model the drainage system, considering factors such as rainfall, sea level rise, and land subsidence in Pekalongan City. The modeling is conducted by integrating 2D and 1D models using the Personal Computer Storm Water Management Model (PCSWMM) software. The modeling results encompass three parameters: flood depth, flood velocity, and flood duration. Subsequently, a flood hazard map is developed based on the Flood Hazard Index, incorporating these three parameters. Recommendations to address this issue include constructing embankments and flap gates upstream in flood-affected areas, as well as modifying the drainage system to enable gravity-driven water flow downstream without the use of pumps. However, it is essential to note that these recommendations may not be effective in scenarios involving significant land subsidence. This research is anticipated to assist stakeholders in making informed decisions regarding the management of the drainage system in Pekalongan City. Keywords: Drainage, PCSWMM, flood, sea level rise, land subsidence
