Agricultural drainage ditches are essential for the removal of surface and ground water to
allow for crop production in poorly drained agricultural landscapes. Ditches also mediate the …

This paper reviews the characteristics, benefits, and drawbacks of agricultural ditches and
wetlands, as well as strategies for applying agricultural best management practices (BMPs) …

Excess nitrogen (N) causes numerous water quality problems, and in the upper Mississippi
River Basin, much of the excess N results from landscape modifications necessary for row …

Outlined is a practical approach to size and modify agricultural drainage channels to two-
stage geometry to maintain drainage function and capacity while increasing channel …

Straight, trapezoidal-shaped surface drainage channels efficiently drain the soil profile, but
their deviations from natural fluvial conditions drive the need for frequent maintenance …

Water quality and stream habitat in agricultural watersheds are under greater scrutiny as
hydrologic pathways are altered to increase crop production. Agricultural drainage ditches …

This paper presents case studies with two-stage channel geometries that were sized based
on geomorphic principles. Geomorphic data were collected at the project site and …

Widden Brook in the Hunter Valley, Australia, was first settled by Europeans in 1831 and
had widened substantially by the 1870s due to frequent floods during a flood-dominated …

Agricultural headwater streams are important pathways for diffuse sediment and nutrient
losses, requiring mitigation strategies beyond in-field measures to intercept the transport of …

The mineral and organic materials in drainage ditches, when stable, may form soils as
defined as materials that can support rooted vegetation or form horizons through processes …
