The housing environment that appears in many urban areas today, is available in the form of real estate and in the form of simple housing. The existence of these houses is equipped with supporting infrastructure. One of them is the availability of open space as a public facility, which can be utilized by all residents of housing. If you look at the historical aspects of past traditional settlements, such as the Tanean Lanjang Madura settlement, the Samin Bojonegoro Community Village, the Sumatra Karo Batak Village, and so on, it is found that there is open space as a public space. Where the function and role of open space are used for joint activities, gathering places and socializing, as well as the center of orientation of several groups of houses, so that the location tends to be in the center. The purpose of this study is to see the existence of open space of traditional settlements (past) and present. As well as analyzing the activities carried out by the pas community and its current development. By using the method of field observation (observation) and qualitative descriptive analysis, the results show that the existence of open space in the present, such as in residential or residential groups, still exists. If in the past traditional settlements, the existence of open spaces was used as a means to gather and socialize, then in its current development, open space could be used as a means of playing and exercising for children, recreational activities (gathering on holidays), supported economic activities (traders who sell), as well as a means of worship (Eid al-Fitr / Eid al-Adha). This shows the development and diversity of functions and activities in the open space, so that its utilization can increase economic values, religious values and other social values.

<p>Rapidly expanding cities are exposed to higher damage potential from floods, necessitating effective proactive management using technological developments in remote sensing observations and hydrological modelling.  In this study we tested whether high resolution topographic data derived by Light and Detection Ranging (LiDAR) and Unmanned Aerial Vehicle (UAV) systems can facilitate rapid and precise identification of high-risk urban areas, at the local scale. Three flood prone areas located within the Greater Accra Metropolitan Area in Ghana were surveyed by a UAV-LiDAR system. In order to simulate a realistic flow of precipitation runoff on terrains, Digital Terrain Models (DTM) including buildings and urban features that may have a substantial effect on water flow pathways (DTMb) were generated from the UAV-LiDAR datasets. The resulting DTMbs, which had a spatial resolution of 0.3 m supplemented a satellite-based DTM of 10 m resolution covering the full catchment area of Accra, and applied to a hydrologic screening model (Arc-Malstrøm) to compare the flood simulations. The precision of the location, extent and capacity of landscape sinks were substantially improved when the DTMbs were utilized for mapping the flood propagation. The semi-low resolution DTM projected unrealistically shallower sinks, with larger extents but smaller capacities that consequently led to an overestimation of the runoff volume by 15% for a sloping site, and up to 65 % for 1st order sinks in flat terrains. The observed differences were attributed to the potential of high resolution DTMbs to detect urban manmade features like archways, boundary walls and bridges which were found to be critical in predictions of runoff’s courses, but could not be captured by the coarser DTM. Discrepancies in the derived water volumes using the satellite-based DTM vs. the UAV-LiDAR DTMbs were also traced to dynamic alterations in the geometry of streams and rivers, due to construction activities occurring in the interval between the aerial campaign and the date of acquisition of the commercially available DTM. Precise identification of urban flood prone areas can be enhanced using UAV-LiDAR systems, facilitating the design of comprehensive early flood-control measures, especially in urban settlements exposed to the adverse effects of perennial flooding.

Abstract. The extent of coastline urbanization reduces their resilience to flooding, especially in low lying areas. The study site is the Emilia-Romagna Region coastline (Italy), historically affected by marine storms and floods. The main aim of this study is to investigate the vulnerability of this coastal area to marine flooding by considering the dynamics of the forcing component (Total Water Level) and the dynamics of the receptor (urban areas). This was done by comparing the output of the three flooding scenarios (10, 100 and >100 year return periods) to the output of different scenarios of future urban growth up to 2050. Scenario-based marine flooding extents were derived by applying the Cost-Distance tool of ArcGIS® to a high resolution Digital Terrain Model. Three scenarios of urban growth (similar-as-historic, compact and sprawled) up to 2050 were estimated by applying the cellular automata based SLEUTH model. The results show that, if the urban growth is compact-like, flood-prone areas will largely increase with respect to similar-as-historic and sprawled growth scenarios. Combining the two methodologies can be useful for identify flood-prone areas that have a high potential for future urbanization, and is therefore crucial for coastal managers and planners.

The Impact

Flood hazard mitigation in urban areas crossed by vegetated flows can be achieved through two distinct approaches, based on structural and eco-friendly solutions, referred to as grey and green–blue engineering scenarios, respectively; this one is often based on best management practices (BMP) and low-impact developments (LID). In this study, the hydraulic efficiency of two green–blue scenarios in reducing flood hazards of an urban area crossed by a vegetated river located in Central Tuscany (Italy), named Morra Creek, were evaluated for a return period of 200 years, by analyzing the flooding outcomes of 1D and 2D unsteady hydraulic simulations. In the first scenario, the impact of a diffuse effect of flood peak reduction along Morra Creek was assessed by considering an overall real-scale growth of common reed beds. In the second scenario, riverine vegetation along Morra Creek was preserved, while flood hazard was mitigated using a single vegetated flood control area. This study demonstrates well the benefits of employing green–blue solutions for reducing flood hazards in vegetated rivers intersecting agro-forestry and urban areas while preserving their riverine ecosystems. It emerged that the first scenario is a valuable alternative to the more impacting second scenario, given the presence of flood control areas.

Abstract. Today, regional spatial planning is one of the challenges in the development of a city. Indications of the development of the city can be seen from the increase in the area built due to an increase in population. As a result, city space is limited, so much urban land is used illegally or not in accordance with the rules of the Spatial Detail Plan (RDTR). Singaporean urban RDTR 2017-2037 has been established and is suitable as a guideline for spatial planning in Tasikmalaya Regency. Also stated in PP number 15 of 2010 in article 101 it is necessary to monitor the use of space every year by the civil service investigating agency (PPNS). The compilation was based on Minister of Public Works Regulation No.20 of 2011 to Minister of ATR Regulation No.16 in 2018. The Singaporean RDTR was prepared in 2011, so monitoring needs to be carried out as a condition for evaluating when there is a change in the legal umbrella. The purpose of this study are: find out the percentage of development realization based on physical conditions in the field; know the development progress in the singaparna urban priority area; and find out trends in spatial development in Singaparna Urban Priority Areas. The method used is a quantitative method (suitability analysis of spatial use and spatial analysis) and qualitative (descriptive analysis). The results obtained from this study are the progress of spatial use in the Singapore Priority Area which shows that there are still many incompatibilities with the RDTR, and the development of the Singapore priority area. In knowing the progress of spatial use by PPNS there needs to be an efficient method in gathering data, then the UAV is one of the efforts in the efficiency of data analysis materials for monitoring space utilization. Abstrak. Dewasa ini tata ruang wilayah menjadi salah satu tantangan dalam perkembangan sebuah kota. Indikasi perkembangan kota dapat dilihat dari meningkatnya kawasan terbangun akibat dari bertambahnya jumlah penduduk. Akibatnya terbatasnya ruang kota, maka banyak lahan kota dimanfaatakan secara illegal atau tidak sesuai dengan aturan Rencana Detail Tata Ruang (RDTR). RDTR perkotaan Singaparna 2017-2037 telah ditetapkan dan layak sebagai pedoman untuk perencanaan tata ruang di Kabupaten Tasikmalaya. Selain itu tertuang dalam PP nomor 15 tahun 2010 dalam pasal 101 perlu adanya pemantauan pemanfaatan ruang setiap tahunnya oleh badan penyidik pegawai negeri sipil (PPNS). Penyusunan tersebut berlandaskan pada Peraturan Menteri PU No.20 tahun 2011 menjadi Peraturan Menteri ATR No.16 tahun 2018. Penyusunan RDTR perkotaan Singaparna dilakukan pada tahun 2011, maka perlu dilakukan pemantauan sebagaimana syarat dalam melakukan evaluasi ketika adanya perubahan payung hukum. Tujuan dari penelitian ini yaitu: mengetahui persentase realisasi pembangunan berdasarkan kondisi fisik dilapangan; mengetahui perkembangan pembangunan dikawasan prioritas perkotaan singaparna; dan mengetahui kecenderungan pembangunan ruang di Kawasan Prioritas Perkotaan Singaparna. Metode yang digunakan adalah metode kuantitatif (analisis kesesuaian pemanfaatan ruang dan analisis spasial) dan kualitatif (analisis deskriptif). Hasil yang diperoleh dari penelitian ini yaitu progres pemanfaatan ruang di Kawasan Prioritas Perkotaan Singaparna yang menunjukan masih banyak ketidak sesuaian dengan RDTR, dan perkembangan kawasan prioritas perkotaan Singaparna. Dalam mengetahui progres pemanfaatan ruang oleh PPNS perlu adanya metode yang efisien dalam pengumpulan datanya, maka UAV adalah salah satu upaya dalam efisiensi bahan data analisis pemantauan pemanfaatan ruangnya.

Various infrastructures such as flood levees, dams and reservoirs of flood control began to be developed in the 19th century to the 20th century. These buildings are very effective in controlling the flow of rivers and preventing flood waters from entering residential areas located in flood-prone areas. Flooding in urban areas has a huge impact, covering all aspects of life as well as on the landscape. Ciliwung is one of the rivers that allegedly contributed to the problem of flood in Jakarta, various engineering done on Ciliwung to help control flooding in Jakarta. One of the engineering done is the construction plan of Ciawi Reservoir and Sukamahi Reservoir. In this research, the writer performed the flood calculation using Nakayasu while method of flooding is calculated using the pool routine level method. The effectiveness of these two reservoirs can be determined by simulating floods in the existing condition and comparing them with the flood simulation after the construction of the dam. The final test of this research is to determine the effectiveness level of Ciawi and Sukamahi dam infrastructure in reducing flood volume in Jakarta.
