摘要

在本研究中，我们展示了一种基于雨水排水网络能力的城市洪水易损性评估方法。利用45 a的日降水资料，生成了2、5、10、50和100 a回归期的强度持续频率(IDF)曲线。随后，利用US-EPA的SWMM软件中的降雨径流模拟，对每种可能的风暴进行了暴雨排水网络的性能评估。考虑了不同回归期暴雨下各排水节点的洪水持续时间，以确定城市的洪水易发区域。据观察，目前约有21%的城市处于城市洪水严重程度高和非常高的地区。

Urban flood vulnerability assessment of Vadodara city using rainfall–run-off simulations

In this study, we demonstrate an approach for citywide urban flood vulnerability assessment based on the capability of storm-water drainage network. The daily rainfall data of 45 years was used for generating Intensity Duration Frequency (IDF) curves of 2, 5, 10, 50 and 100 year return period. The performance of the storm-water drainage network was subsequently evaluated for each of these probable storms using rainfall-runoff simulations in US-EPA's SWMM software. The duration of flooding at drainage nodes under storms of different return period was considered for identifying flood-prone regions in the city. It was observed that about 21% of the city is currently under high and very high urban flood severity zones.

期刊介绍： Current Science, published every fortnight by the Association, in collaboration with the Indian Academy of Sciences, is the leading interdisciplinary science journal from India. It was started in 1932 by the then stalwarts of Indian science such as CV Raman, Birbal Sahni, Meghnad Saha, Martin Foster and S.S. Bhatnagar. In 2011, the journal completed one hundred volumes. The journal is intended as a medium for communication and discussion of important issues that concern science and scientific activities. Besides full length research articles and shorter research communications, the journal publishes review articles, scientific correspondence and commentaries, news and views, comments on recently published research papers, opinions on scientific activity, articles on universities, Indian laboratories and institutions, interviews with scientists, personal information, book reviews, etc. It is also a forum to discuss issues and problems faced by science and scientists and an effective medium of interaction among scientists in the country and abroad. Current Science is read by a large community of scientists and the circulation has been continuously going up. Current Science publishes special sections on diverse and topical themes of interest and this has served as a platform for the scientific fraternity to get their work acknowledged and highlighted. Some of the special sections that have been well received in the recent past include remote sensing, waves and symmetry, seismology in India, nanomaterials, AIDS, Alzheimer''s disease, molecular biology of ageing, cancer, cardiovascular diseases, Indian monsoon, water, transport, and mountain weather forecasting in India, to name a few. Contributions to these special issues ‘which receive widespread attention’ are from leading scientists in India and abroad.
