摘要

最近,日本兵库县扩大了在县内使用木堰板的稻田水坝活动。在水田排水口放置木堰板,限制水田排水,使水田在一定程度上储存雨水。由于对防洪效果的估计不合理,我们利用木堰板进行了田间试验,以估计堰系数,该系数决定了稻田的排水流量与水深的一致。然后,利用估算的堰系数,我们建立了一个3000平方米的水田坝模型。此后,我们将该模型应用于考虑2009年和2011年降雨事件的Suse地区(约33公顷)。结果表明,水田坝对水田坝址近下游地区的洪峰流量降低效果较大(2009年约为25.2%,2011年约为48.5%)。然而,模拟结果表明,在极端降雨条件下,如2009年,由于稻田水深的增加,稻田坝活动可能造成稻田堤防的侵蚀。

Estimation of paddy field dam effect on flood mitigation focusing on Suse region of Hyogo, Japan
: Recently, Hyogo Prefecture in Japan has expanded its paddy field dam activity within the prefecture using wood weir plates. A wood weir plate was placed at the drainage outlet of a paddy field to limit drainage from the field, thus enabling the paddy fields to store rainwater to a certain extent. As the effect on flood mitigation was not appropri‐ ately estimated, we carried out a field experiment using a wood weir plate to estimate the weir coefficient, which determines the drainage discharge from the paddy accord‐ ing to the water depth. Then, using the estimated weir co‐ efficient, we developed a 3,000 m 2 paddy field dam model. Thereafter, we applied the model to the Suse region (approximately 33 ha) considering the 2009 and 2011 rain‐ fall events. It was observed that the paddy field dam has a relatively large effect on reducing the peak discharge (approximately 25.2% for 2009 and 48.5% for 2011) within the proximal downstream areas of the paddy dam site. However, the simulation showed that when the rainfall is extreme, as was the case in 2009, the paddy dam activity may cause erosion of the paddy levee due to the increase in the paddy water depth.

期刊介绍: Hydrological Research Letters (HRL) is an international and trans-disciplinary electronic online journal published jointly by Japan Society of Hydrology and Water Resources (JSHWR), Japanese Association of Groundwater Hydrology (JAGH), Japanese Association of Hydrological Sciences (JAHS), and Japanese Society of Physical Hydrology (JSPH), aiming at rapid exchange and outgoing of information in these fields. The purpose is to disseminate original research findings and develop debates on a wide range of investigations on hydrology and water resources to researchers, students and the public. It also publishes reviews of various fields on hydrology and water resources and other information of interest to scientists to encourage communication and utilization of the published results. The editors welcome contributions from authors throughout the world. The decision on acceptance of a submitted manuscript is made by the journal editors on the basis of suitability of subject matter to the scope of the journal, originality of the contribution, potential impacts on societies and scientific merit. Manuscripts submitted to HRL may cover all aspects of hydrology and water resources, including research on physical and biological sciences, engineering, and social and political sciences from the aspects of hydrology and water resources.
