Water Surplus - GCSE Geography Definition

Water surplus refers to a situation where an area has more water than it needs for its population and environment. This happens when the amount of water available from sources like rivers, lakes, and rainfall is greater than the amount used for things like drinking, farming, and industry. In places with a water surplus, there might be enough water to store for times of less rain or to share with areas suffering from water shortages. Areas with high rainfall and low population might often experience a water surplus, helping to support local ecosystems and agriculture.
