What is a "hydrologic model" used for in stormwater management?

A hydrologic model is an essential tool in stormwater management that simulates how water moves through the landscape after a storm event. This type of modeling allows professionals to understand and predict the quantity, direction, and timing of stormwater runoff generated by various rainfall events. By incorporating data such as land use, soil type, precipitation rates, and the characteristics of drainage systems, hydrologic models help in assessing how water interacts with the environment.

The primary focus of a hydrologic model is on the behavior of stormwater, including how it flows across surfaces, infiltrates into the ground, or is absorbed by vegetation. This information is crucial for designing effective stormwater management practices, such as detention basins, green roofs, or permeable pavements, that aim to control flood risks, reduce erosion, and improve water quality.

In contrast, monitoring pollutant levels, tracking water temperatures, and assessing soil quality are important aspects of water management, but they do not directly involve the simulation of stormwater behavior. These activities focus more on water quality management and ecological assessment rather than on the hydrological processes themselves. Therefore, the application of a hydrologic model in stormwater management is particularly targeted toward understanding and managing runoff dynamics, making the identified
