Hydrologic Calculations

This chapter covers the principles of hydrologic calculations as they relate to stormwater. This chapter covers the principles of hydrologic calculations as they relate to stormwater management. Discussed in this chapter are the elements of the hydrologic cycle that affect the rainfall–runoff relationship. These elements include the rainfall process, vegetal interception, surface retention, and infiltration. Also discussed in this chapter are runoff calculation methods and their limitations. A physically based model developed by the author is also presented in this chapter. Ample examples and case studies are included in illustrate proper application of hydrologic methods.
