-Proper ditching can be a
key component of successful runoff diversion, as ditches collect and store
storm water until it can be deposited into buffers and absorbed into the
ground
-The best ditches are
trapezoidal or parabolic, which slows water flow and prevents erosion
-A moderate amount of
vegetation within the ditch also helps with absorption and flow rate, though
too much material can inhibit water movement. Stones and grass are useful
materials to have in ditches
