Two common methods used to control floods are the construction of levees and the implementation of flood control reservoirs. Levees are earthen embankments built alongside rivers to prevent overflow during high water events. Flood control reservoirs are large artificial lakes designed to temporarily store excess water, reducing the flow downstream and minimizing flood risk. Both methods aim to manage water levels and protect communities from flood damage.

In ancient Mesopotamia, two key methods used to control annual floods were the construction of levees and the development of an extensive irrigation system. Levees, or raised banks, were built along riverbanks to prevent overflow during peak flood seasons. Additionally, the irrigation system allowed for the diversion of river water to agricultural fields, managing both the water supply and mitigating flood risks while ensuring reliable crop production.

Europeans used various methods to control their colonies, two of which were direct rule and indirect rule. Direct rule involved the replacement of local leaders with European officials, allowing for direct governance and imposition of European laws and customs. Indirect rule, on the other hand, retained local rulers in power but under European supervision, allowing for some degree of local autonomy while still ensuring that European interests were prioritized. Both methods aimed to establish and maintain control over colonized regions while minimizing resistance.
