城市雨洪管理是海绵城市建设的重要组成部分,但目前我国的城市雨洪水文模拟实践在两个方面存在一定的不足:首先,普遍采用在理论方面存有缺陷的上行法;其次,没有考虑流量衰减作用的影响。鉴于此,介绍在国际上更为先进的下行模拟方法,并通过具体的案例对其应用方法进行阐述,从而启发相关工作者高效制定城市雨洪管理方案。 Urban stormwater management is an important part of sponge city construction. At present, there are some deficiencies in the practice of urban stormwater flood simulation in our country. Firstly, the upward method with defects in theory is generally adopted. Second, Effect of flow attenuation. In view of this, we introduce the more advanced downstream simulation methods in the world and explain the application methods in specific cases so as to inspire the relevant workers to effectively develop the urban stormwater management solutions.
