Moisture Flow Optimization In Porous Media For Land Leaching And For Seedbed Design , Stephen Bruce Affleck

Retrospective Theses and Dissertations

Two problems on optimization of fresh water management in porous media soil systems were investigated. The first problem dealt with the use of surface barriers on tile-drained land during leaching operations. The barriers were designed to prevent direct flow to underlying tile drains and make leaching more efficient. The 0.1 m diameter tile drains were imbedded in an impermeable layer 2 m below the ground surface and drain spacings of 4, 8 and 16 m were investigated. Calculations were made for surface barriers that covered 25, 50 and 75 percent of the land for each case of tile spacing ...
