Land cover change effects on stormflow characteristics across broad hydroclimate representative urban watersheds in the United States
Kul Bikram Khand, Gabriel B. Senay
2022, Water (14)
Urban development alters stormflow characteristics and is associated with increasing flood risks. The long-term evaluation of stormflow characteristics that exacerbate floods, such as peak stormflow and time-to-peak stormflow at varying levels of urbanization across different hydroclimates, is limited. This study investigated the long-term (1980s to 2010s) effects of increasing urbanization...
