Numerical Analysis of Potential Contributions of the Proposed Huangpu Gate to Flood Control in Taihu Lake Basin
Zhang Hanghui et al.

The authors present an applied research of assessing the potential contributions of the proposed Huangpu gate (as an estuary gate) to flood control capacity of the Taihu Lake Basin in China. A particular advantage of this paper is that the study focuses on the quantitative analyses of the potential benefits of the proposed Huangpu gate through numerical simulations based on various flooding scenarios. It represents a major new contribution to the literature from both scientific and engineering points of view.

Authors refer to two types of floods in the Taihu Lake basin (i.e. monsoon-induced and typhoon-induced floods), and the basin is impaced by both marine (e.g. tides, storm surges) and river flooding & waterloddging. The methodology section leaves the reader with an expectation of applications of the HOHY model to investigate the potential impacts of different operating modes of the gate to the flood control of the basin for typical flood events mentioned above, such as the 1999 flood, the 1991 flood. However, this expection goes unfulfilled in the result analysis and discussion sections, and the reader is left wondering why scenario analysis was made only for the 1999 flood event.

More minor modifications should include:

1)The introduction should point out the issues you want to study, review the research advances in international hydrology society, and present the main research content of the paper. In this regards, it is suggested for authors to review the techniques and approaches adopted for impact study on flood control by operating estuary barries in Japan, England, Netherland and other countries, and evaluate the innovation or new findings in this applied research. In other words, it should indicate why the reader should be interested in reading the paper?
2)Detailed about the study area of the Taihu Lake should moved from Introduction to Study Area section.
3)More information about the typical floods in the Taihu Lake basin (e.g. the 1999 flood , the 1991 flood) should be given in Study Area section, including the causes of the flooding (e.g. Rainstorm, astronomical tide, storm surge).
4)General information about sedimentation in Huangpu river and estuaries is needed to supplement in Study area section.
5)In 3.1 Scenarios description (Page 4 Line 20-35 ), authors describes five scenarios used in the study. The reader wonder about the criteria or principles of proposing the five scenarios. What are the main factors to be considered in the gate operation scenarios dessign?
6)In 3.2 Model description (Page 5 Line 12-35 ), authors should also say if this is the first presentation on the HOHY model in an international Journal. A brief introduction on the HOHY model’s structure and methodology, and further development of the model by authors in this study are also recommended to be added in the paper.
7)Page 1 Line 19: Change “access” to “assess”
8)Page 5 Line 6: “the ehorage” . What does it mean?
9)Page 1 Line 5: change “Ministry of Water Resources” to ”Ministry of Water Resources of P.R. China”
10)Figure 1(a) and (b): Please show rivers of Wangyu and Huangpu, location of Huangpu Park station in the map. Boundaries of six hydrology units and rivers are not clearly distinguished in the fig. 1. Can they be refined with amendation?

Short summary

The Huangpu River, an important river of the basin connecting Lake Taihu upstream and the Yangtze River estuary downstream, drains two-fifths of the entire basin. Constructing an estuary gate is considered an effective solution for flood mitigation. The main objective of this paper is to assess the potential contributions of the proposed Huangpu Gate to the flood control capacity of the basin. Results of quantitative analyses show that the Huangpu Gate is effective at evacuating floodwaters.
