The Technical Release 55 (TR-55) is a widely used hydrology tool developed by the Natural Resources Conservation Service (NRCS) to aid in the computation of direct runoff and peak discharge from rainfall events. This established method provides engineers, hydrologists, and land managers with a framework to assess watershed response to various land use and soil conditions. TR-55 offers valuable insights for designing stormwater management systems, erosion control measures, and flood mitigation strategies. Its equations and procedures continue to assist professionals in making informed decisions to promote sustainable water resource management.
