The diagram delineates two methods that can be used for the prevention of the houses situated in flood-prone areas. These methods are basically classified on the usage of stop bank on the ground.
Overall, after a rainfall, rainwater gathers in a river or drain through internal run-off and
the river consists of a 100-year old flood level. However, a foot of a stop bank contains two components berm and floodgate. While, freeboard's tip signifies the height of stop bank and usually it's bottom starts from the 100-year old flood level.
Moreover, in a area where there is no stop bank constructed, building's height is merely raised in accordance with freeboard which is 300mm above flood-level. Although, stop bank is not present, buildings are prevented from the flood by escalating the height of the houses and matching the level of house floor and freeboard.
Thus, the diagram clearly illustrates the preventive measures taken for the houses dwelling in the areas which are prone to flood.
