Subsurface Erosion PowerPoint PPT Presentations

Soil piping is a type of subsurface erosion that involves the hydraulic removal of subsurface soil to form underground tunnels. While no massive catastrophes have been reported, it decreases agricultural productivity and contributes to inhospitable terrains. Do you have what it takes to design a viable alternative to soil piping?
