Detailed explanation-1: -In many countries, flood-prone rivers are often carefully managed. Defenses such as dykes, reservoirs and dams are used to keep rivers from overflowing. A dam is one of the methods of flood protection, which reduces the risk of flooding compared to other methods, once it can help preventing damage.
Detailed explanation-2: -This is so that when the monsoon rains come, there is space to store the excess rainwater and also so that water can be released in a regulated manner, thus preventing floods downstream when there is heavy inflow to the dams.
Detailed explanation-3: -During heavy rainfall, the dam stops the water from overflowing in the particular area. When the height of the dam is low, the gates of the dam opens up. So, the excess water flows into the area of livelihood. This causes flooding.
Detailed explanation-4: -Elevate the furnace, water heater, air conditioner and other utilities. Install “check valves” in sewer traps to prevent flood water back ups. Construct interior barriers to stop low level floodwater from entering basements. Seal walls in basements with waterproofing compounds to avoid seepage. More items
