A unit hydrograph is a graphical representation that shows the response of a watershed to a unit input of rainfall over a specified duration, typically one inch or one centimeter, and is used to predict streamflow at a given location. This tool connects rainfall events with their corresponding runoff, enabling hydrologists to analyze the timing and volume of water flow in rivers and streams. Understanding unit hydrographs helps in flood forecasting, water resource management, and designing effective stormwater management systems.
