Water allocation refers to the process of distributing available water resources among different users, such as agricultural, industrial, and domestic sectors, in a sustainable and equitable manner. This research area involves studying the methods, policies, and institutions governing water allocation, including water rights, water pricing, water markets, and water management techniques. Researchers in this field explore the various factors influencing water allocation decisions, such as population growth, climate change, and competing demands for water resources. The ultimate goal of water allocation research is to ensure efficient and fair distribution of water resources to meet the needs of all users while also protecting the environment.
