“…Air yang akan terus tertahan di permukan tersebut kemudian menjadi kumpulan air yang dinamakan genangan (Bisri et al, 2012). Curah hujan dengan intensitas tinggi untuk waktu yang lebih singkat menghasilkan limpasan puncak yang tinggi dari daerah tangkapan perkotaan untuk lebih banyak lahan, dan pembangunan infrastruktur yang tidak terkendali, penggunaan lahan alami, tutupan lahan, dan jalur aliran telah mengakibatkan banjir (Rangari et al, 2019).…”

Banjir merupakan salah satu bencana alam yang sering melanda berbagai daerah di Indonesia. Penelitian ini dilatarbelakangi oleh kondisi drainase di Kampus USU dengan luas lahan ±143 Ha terlihat tidak mampu menampung besarnya debit yang masuk baik disebabkan oleh daya tampung yang lebih kecil dari debit yang ada, kurangnya perawatan maupun sistem pengaliran dan pembuangan yang tidak sesuai lagi dengan lingkungan dan sebagainya. Studi ini bertujuan untuk mengetahui potensi genangan banjir di Kawasan Kampus USU dengan menghasilkan peta genangan banjir dari integrasi pemodelan antara software Hydrologic Engineering Center-River Analysis (HECRAS) dengan Geografic Information System (GIS). Dalam melakukan studi ini dilakukan pengumpulan data yang mencakup data topografi Kampus USU, data curah hujan dari BMKG, data tata guna lahan, data Topografi LIDAR. Metode Log Person III memenuhi syarat agihan distribusi frekensi curah hujan. Perhitungan debit banjir periodik menggunakan Metode Rasional untuk kala ulang banjir 1, 2, 5, 10, 20, 25, 50, dan 100 tahun. Dari hasil simulasi yang dilakukan terlihat daerah genangan yang terjadi di Kawasan Kampus USU. Beberapa lokasi banjir yang terjadi di Kampus USU adalah Jalan Universitas mulai dari depan Gelanggang Mahasiswa sampai persimpangan Jalan Dr. Mansur, Sepanjang Jalan Dr. Mansur, Fakultas Kesehatan Masyarakat, Fakultas Hukum

“…These include nonstructural measures such as the installation of automatic weather stations for rainfall monitoring [17] and dissemination of real-time rainfall and flood alerts in Mumbai which can be seen on http://dm.mcgm.gov.in/livefullpage as well as on smartphones. Flood risk mapping has been carried out for a few cities, for example, Mumbai [18], Chennai [19], Surat [20], and Hyderabad [21], while flood risk assessment and resilience strategies have been identified for Surat [22]. A study to understand vulnerability to increased precipitation in a changing climate and identify flood zones and hazards, it has been difficult to prevent new building in the hazardous areas due to paucity of space and difficulty in the evacuation of the squatters.…”

This note presents a short commentary on the recurring urban flooding in India and the challenges the country faces in implementing sustainable drainage practices and developing urban flood resilience. The major incidences of heavy rainfall and the consequent urban flooding and their causes are briefly described. The recent flood disaster management and mitigation measures carried out by the Central, State and Local Government are highlighted. The flood resilience initiatives and challenges are then discussed. The effects of climate change on increased rainfall in shorter durations are now being felt in many Indian cities. The planners are now taking cognizance of this and future flood resilience measures are being planned to incorporate an integrated approach to stormwater management by recommending best management practices in the stormwater manuals. However, a lot still needs to be done to make the cities in India flood resilient. This article is part of the theme issue ‘Urban flood resilience'.

“…Construction activities on lake and river bed have pushed more people toward high vulnerability to floods. Water bodies in the area are reduced from 2.28 to 1.64% from 2001 to 2016 [14]. Area under water bodies reduced from 5949.28 ha in 2001 to 4764.73 ha in 2015, that is, area of 84.61 ha/year of water bodies has vanished [15].…”

Flood Impact Mitigation and Resilience Enhancement

View full text Add to dashboard Cite

Cities are increasingly faced with frequent floods disrupting everyday lives. Adapting to flood risks and conserving eco-sensitive sites are central to social ecological resilience. Rapidly expanding cities are found short of mitigating the adverse environmental impacts. For enhancing flood resilience, it is important to understand the interaction of the key stakeholders and its impact on governance and land use in the cities. Land use change in urban space is constantly influenced by negotiations among various interest groups. The urban governance structures are increasingly dominated by neoliberal approaches of profit maximization. Following a heuristic framework for policy analysis of land use change and governance, the present study assesses the barriers in building flood resilient cities. We apply the framework to Hyderabad city of Telangana, India, which has faced the recurring challenge of flooding. Results demonstrate the lack of urgency in implementing disaster management initiatives and contradictions in existing policies. This study points out the redundancy of elected municipal bodies for taking flood resilience measures, due to increasing proliferation of nondemocratic administrative bodies and underlines the need to bridge the gap through agendas cutting across sectors and institutions.
