雨水管理和道路隧道（SMART）的建造是为了在位于大城市地区的两条主要河流的主要交汇点周围引导水；此外，它还兼作公路隧道，尽管这一段只在大风暴中使用。马来西亚灌溉和排涝部（DID）以数据和报告的形式提供了许多信息。利用工程前的历史水流数据以及简单的速度-面积计算来确定隧道容量，以评估其效率。来自DID的水位数据被用来创建一个图表，以计算产生洪水的最小水量。对这些信息的处理表明，SMART本身就是一种有效的洪水威慑，因为它的水容量和它产生的滞后时间。虽然大多数风暴应该很容易处理，但SMART只从其中一条河流的关键交汇点附近调水。它对另一条河的流量没有影响，但它导致了持续的水流出。例如，这条河每隔100年平均一次的降雨将淹没吉隆坡。尽管SMART的发展被认为是成功的，然而，城市其他部分的不断发展并不能确保不会发生洪水，也不能彻底保护城市中心。
Storm water management and road tunnel (SMART) was built to direct water around a major meeting point of two major rivers located in a large urban area; in addition, it doubles up as a road tunnel, though that section is only used in major storms. Much information has come from the Malaysian Department of Irrigation and Drainage (DID), in the form of data and reports. Pre-project historical water flow data as well as a simple velocity-area calculation to find the tunnel capacity was used to assess its efficiency. Water level data from the DID was used to create a graph in order to calculate the minimum amount of water to create flooding. Processing this information has revealed that SMART is in itself an effective flood deterrent, due to its water capacity and the lag time it creates. Although most storms should be easily dealt with, SMART only diverts water around the critical meeting point from one of the contributing rivers. It has no effect on the flow from the other river but it caused the sustained water to flow out. For an example, rainfall from a 100 year average return interval from this river will flood Kuala Lumpur. Although the development of SMART has been considered as successful, however, the growing development in the other part of the city could not ensure no flooding will take place or thoroughly protect the city centre.   Key words: Discharge, confluence, rainfall, storm water, drainage, frequency.
