land using the real surface of the line you are creating to determine if the DITCH pass will work
and roughly how much earth will need to be moved to make it drain properly.
Figure 15: Drainage Parameters
It is up to the user to decide what parameters work best for each situation, but typically on land
that is filled with hills and rapidly changing elevations, you can make a ditch with the
parameters below:
•
Minimum Depth:
0.2
–
0.75
•
Optimum Depth:
0.75
–
2.00
•
Maximum Depth:
1.50
–
3.00
•
Minimum Slope:
0.05
–
0.2
•
Maximum Slope Change:
2.5
–
3.0
•
Start Distance:
35 - 45
•
Outlet Depth:
0
The above are typical drainage parameters, not absolute. Each case may vary.
