The diagrams below show how houses can be protected in areas that are prone to flooding. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
The diagram illustrates the estimated comparison between the area with a stopbank and the place without a stopbank.
Clearly, it is observed that stopbank plays a vital role in overcoming the effects of the flood.
Primarily, a stopbank is present above the surface of the earth with the altitude of the underside of a structure which is higher than the provided level. The base of the stopbank comprises a floodgate, which is raised from the berm.
Moreover, these freeboards represent the height between the house floor and ponding levels. The effect of the flood on buildings will be slightly declined when they are provided with a stop back. Yet, internal runoff results in the formation of internal ponding in and around the constructions. However, zones lacking stopbank were affected by both 100-year flood levels and internal ponding
At the end of the picture, the stopbank signifies how houses can be protected in areas that are prone to flooding.
