Construction on the coast of Holland is a job that involves building a DIKE, which is a structure made of stone, earth, or other materials that is built to protect land from flooding. The DIKE is typically built along the coast of a body of water, such as a river, lake, or ocean, and is designed to prevent flooding by controlling the flow of water. In Holland, the dikes are an important part of the country's infrastructure, as they help to protect the land from flooding and provide a barrier against the sea.
