Stockpile Drainage Analysis | Stockpile Seepage Analysis
Moisture seepage and drainage. Drainage is the unsaturated flow of water through a mass of solid particles stored at rest in a stockpile. As a result of gravity, water flows downward through the pile. If the pile base is impervious or nearly so, water accumulates at the bottom, the bulk material cannot contain any more liquid, and it becomes ...
