Bowman Creek: Sediment transport and slumping related to the July 2008 flooding

These photos were taken on 17 August 2008 after heavy rain in late July caused severe local flooding in Schenectady County. Localized slumping and slope failure resulted form saturated ground. These pictures are from Bowman Creek, a small tributary of the Schoharie Creek in Schenectady County.

These pictures are high resolution, so this web page will load slowly. These images may be used for non-commercial purposes provided proper credit is given.
