Abstract

Urban flooding is growing as a serious development challenge for cities. Urbanization demands the conversion of pervious land to impervious land by pushing the transformation of water bodies, flood plains, wetlands and green spaces into built-up spaces. This affects the hydrological setting of the city’s geographic area. Bhubaneswar, one of the first planned cities of independent India, has expanded rapidly with an increase in the settlement land use cover from 41 km2 to 81 km2 in the last two decades. Non-consideration of disaster risk assessment in the land use plan has placed the city at high disaster risk. Hence, this article explores various avenues for making a flood resilient city through spatial planning. To understand the flood and its consequences, a flood hazard and vulnerability map was prepared by overlaying the existing social and infrastructure networks, and flood risk zones were generated through analytical spatial modelling in GIS. This accounts for the areas in which flood hazards are expected to occur, as well as the area whose socio-economic and infrastructure susceptibility to the disaster is more. The key outcome is to ensure urban development that can work concurrently with nature by integrating disaster risk reduction strategies into land use planning.
布巴内斯瓦尔城市洪水风险评估与城市抗洪空间规划的制定
城市洪水日益成为城市发展面临的严峻挑战。城市化要求通过推动水体、洪泛区、湿地和绿地向建成区的转变,将透水土地转变为不透水土地。这会影响城市地理区域的水文环境。布巴内斯瓦尔是印度独立后最早规划的城市之一,在过去20年中,随着定居点土地使用面积从41平方公里增加到81平方公里,该城市迅速扩张。土地利用规划未考虑灾害风险评估,使该市处于高灾害风险之中。因此,本文探索了通过空间规划打造抗洪城市的各种途径。为了了解洪水及其后果,通过覆盖现有的社会和基础设施网络编制了洪水危害和脆弱性地图,并通过GIS中的分析空间建模生成了洪水风险区。这说明了预计会发生洪水灾害的地区,以及社会经济和基础设施更容易受到灾害影响的地区。关键成果是通过将减少灾害风险战略纳入土地利用规划,确保城市发展能够与自然同步进行。
