These are two illustrations showcasing flood management. The upper image describes the topic with the existence of a barrier, showcasing how it is above the floodgate with other features that include; a berm, a free board, a stopbank and a 100-year flood level. Hence preventing the water flowing through land and reaching It. This determines how useful a stopbank can be during rainy seasons and in areas that are prone to bad weather conditions.
The second diagram focuses on the effects when there is severe flooding but nothing to block it from affecting land. It causes the water levels to rise, due to the lack of a blocking system; hence making it ends up spilling and going through nearby houses and buildings, especially ones that are floor level, without supportive pillars that prevent the waterways from entering the houses.
In conclusion, having a stable and proper blockage system can be very useful in areas that are prone to flooding, with lack of liquid and safety management.
