- Andrew, The minimum slope for water to run is 1/8" drop per 12" run. I
- would reccomend something a little steeper than this. I believe that a
- 24" drop per 12" run is the maximum and w/o grass or something else to hold
- it, it will wash away.
-
- Sorry I can't be a little more specific, but my landscaping manuals are at
- the office...
-
- To calculate the volume of the soil, use the handy 'area of a triangle'
- formula. (base * height)/2 then multiply this times the length of the
- mound that you make.
-
- eg. a 2 foot wide mound that rises 4" and is 100' long equals:
-
- (24" x 4")/2 = 48 square inches multiply time 1200" (100') = 57,600 cu. in.
-
- Easiest way to figure cu feet is to use foot increments instead of inches,
- hence 4" = 0.33 feet

- Hope it helps, for more info email me at signiture below.
