Runnel Excavation
Runnel excavation is a low-tech method being used in east coast salt marsh (Spartina spp.) that could be applied to River Delta Restoration to increase drainage in sections of restored marsh by excavation of narrow shallow trenches as part of ditech remediation. This is anticipated to support loss of high marsh, and reduce high levels of surface saturation. Runnel excavation is often used in conjunction with ditch remediation.
