Abstract

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'.

摘要

本注释就印度反复出现的城市内涝以及该国在实施可持续排水措施和提高城市防洪能力方面面临的挑战进行了简要评述。简要描述了强降雨的主要事件以及由此导致的城市内涝及其成因。突出介绍了中央、州和地方政府最近采取的洪水灾害管理和缓解措施。然后讨论了洪水恢复力倡议和挑战。气候变化导致短时间内降雨量增加,目前许多印度城市都感受到了这一影响。规划者现在已经意识到这一点,正在计划未来的防洪恢复力措施,通过在雨水管理手册中推荐最佳管理实践,采用综合方法来进行雨水管理。然而,要使印度的城市具有防洪能力,还有很多工作要做。本文是主题为“城市防洪能力”的特刊的一部分。
