Dikes are structures built to control water flow and protect land from flooding. They are typically made of earth, rock, or concrete and are designed to hold back water from rivers, lakes, or oceans. Dikes are commonly found in areas prone to flooding, such as low-lying regions or near coastlines. In addition to flood protection, dikes can also help manage water levels for agriculture and irrigation. They create barriers that can redirect water, allowing for better land use and preventing soil erosion. Dikes are an essential part of water management systems in many countries, including those with extensive canal networks.
