Abstract

Due to the intensive human activities, lots of hydraulic facilities were constructed and have a significant impact on hydrological processes and spatial migration of urban floods. For coastal plain regions, the suffering from rainstorms and storm surges, which was always neglected in previous studies, makes the impact more complex. Thus, the potential impact was observed based on a hydrodynamic model with real-time operations of hydraulic systems. To improve the confidence of the simulation, a joint copula model between maximum rainfall and contemporaneous maximum tide water level was built, which makes up for the lack of consideration in previous coastal flood simulations. Results of quantitative simulation showed that the projects of the Large Encirclement Project in Suzhou urban (LEP) prevented the flood in urban areas efficiently but transferred the flood to the suburb. The Diversion-Drainage System along the Yangtze River (DDS) had a larger impact on the hydrological processes in the northern regions. This will be of great benefit to the flood management in the Taihu Basin.

期刊介绍： JAWRA seeks to be the preeminent scholarly publication on multidisciplinary water resources issues. JAWRA papers present ideas derived from multiple disciplines woven together to give insight into a critical water issue, or are based primarily upon a single discipline with important applications to other disciplines. Papers often cover the topics of recent AWRA conferences such as riparian ecology, geographic information systems, adaptive management, and water policy. JAWRA authors present work within their disciplinary fields to a broader audience. Our Associate Editors and reviewers reflect this diversity to ensure a knowledgeable and fair review of a broad range of topics. We particularly encourage submissions of papers which impart a ''take home message'' our readers can use.
