REader's Digest version: divert incoming groundwater and provide runoff trenches for existing floodwater; roof/side if possible; use downspouts and extensions to divert roof water away from run; add fill if run is below surrounding ground level. You can add almost anything, even pallets, as an emergency temporary measure; but in the long run, your best footing to prevent future mud (once you have conquered the water-input part of the problem) is something inorganic like sand or gravel.
Good luck,
Pat
