How do flow peaks and durations change in suburbanizing semi-arid watersheds ? A southern California case study

  title={How do flow peaks and durations change in suburbanizing semi-arid watersheds ? A southern California case study},
  author={Robert J. Hawley and Brian P. Bledsoe},
Forty-three US Geological Survey gauges with records greater than 15 yrs located in watersheds less than 250 km were used to model the effects of suburbanization on streams in semi-arid southern California. The watersheds spanned a gradient of urban development, ranging 0–23% total impervious area in 2001. With little flow control at the subdivision scale, most impervious area in the region is relatively well-connected to surface-drainage networks and hydrologically effective. Consequently… CONTINUE READING
