Evaluating Geomorphic Change in Constructed Two-Stage Ditches in Ohio, Indiana, and Michigan

Hillsdale County MI

Aired: April 30, 2014 from noon to 1pm Eastern

The two-stage ditch design has potential to enhance ecological services while meeting drainage needs essential for agricultural production. One advantage of the two-stage ditch is that it is more consistent with fluvial form and process than straight trapezoidal-shaped drainage channels. This webinar will present the results of studies of geomorphic change of the inset channel, benches and banks of 7 two-stage ditches constructed in Ohio, Indiana, and Michigan.  Two-stage ditches can be a stable, viable option for drainage ditch management if designed and installed properly on the landscape.
