These instructions are for Form ND-ENG-17a, dated October 2002. The form is a method that may be used to document and compute cleanout volumes for dugout restorations. The process utilizes the prismoidal formula to determine cubic yards. Side (A) gives volume of dugout before cleanout, Side (B) gives volume after cleanout. The difference in volume is cu. yds. removed.
Steps Information Required
Engineering Job Approval Authority, Job Class.
Landowner/Operator where practice is to be installed.
County where practice is to be installed.
Section, Township, Range, Farm No, and Tract of practice location.
Drainage area contributing runoff to dugout.
Check proper source of water, groundwater, or surface water.
Description of bench mark.
Bench mark elevation establish temporary bench mark on site.
Back sight from level set up to establish Height of Instrument (HI).
Bench mark elevation plus back sight equals level elevation, HI.
Indicates name or initials of person completing the computations.
Indicates name or initials of person checking survey notes and computations.
Indicates name or initials of person that has engineering job approval authority.
Indicates dates surveys, computations, and checking were completed by the respective individuals.
Record rod readings at points 6 through 13. These points are located at the slope intercept points. (Only if restored pond has the same or longer top dimensions than the existing pond.)
Add the rod readings from 6 through 13 and divide by 8. This gives an average rod reading to define the elevation of the top of the dugout.
Record rod readings at points 1 through 5 on dugout bottom.
Add the rod readings for points 1 through 5 and divide by 5 to get the average rod reading to define the elevation of the bottom of the dugout.Instructions Form ND-ENG-17a (Contd)
Steps Information Required
Average bottom rod reading (18) minus average top reading (16) equals the weighted depth (Dw).
Average top length of existing dugout (TL) ft.
Average top width of existing dugout (TW) ft.
Average bottom length of existing dugout (BL) ft.
Average bottom width of existing dugout (BW) ft.
Area of top equals TL times TW = (AT) sq. ft.
Area of bottom equals BL times BW = (AB) sq. ft.
Four times the mid area equals the sum of the top length and bottom length times the sum of top width and bottom width equals (4AM) sq. ft.
Sum of Areas = top area plus the bottom area plus four times the mid area.
The volume in cubic yards of the existing dugout equals the weighted depth (19) times the sum of the areas (27) divided by 162.
SIDE B - CONSTRUCTION STAKING OF RESTORED POND
Using the bottom average rod reading (18) from Side A of form, add the additional desired depth. This will give you the grade rod (29) for the restored dugout.
In Step B you have two options. (B1) should be used if the new pond is located directly over the old pond. Points 6 through 13 are identical points for both Side A & B of the form.
If the pond is to be enlarged (B2) should be used. Points 6 through 13 need to be reset to the desired top length and top width.
It is important that the sides and the ends of the top area are parallel. Form as nearly as possible a perfect rectangle or square in either case (B1) or (B2).
Rod readings at points 6 through 13 from Side A of the form.
To determine the cuts at points 6 through 13 under (B1) subtract the rod reading at each of these points (30) from the grade rod (29).Instructions Form ND-ENG-17a (Contd)
Steps Information Required
If the dugout is going to be enlarged, the points 6 through 13 are reset. (B2) rod readings at each of these points are then taken, added together and then divided by eight to get an average top rod reading (32). The new cuts are determined by subtracting the new readings at points 6 through 13 (30) from the grade rod (29).
In Step C, determine the dimensions of the bottom of the restored dugout. This is accomplished by computing the slope lengths and subtracting from the top length and top width of the dugout.
The average top width TW (33) is (the length from flag 6 to 9 + the length from flags 13 to 10) divided by 2.
The average bottom width BW (34) is calculated by the average top width TW (33) minus the average horizontal side slope length. The average horizontal side slope length is the (horizontal side slope lengths from flags 6 to 2 + 3 to 9 + 13 to 5 + 4 to 10) divided by 2.
The average top length TL (35) is (the length from flags 7 to 12 + the length flags 8 to 11) divided by 2.
The average bottom length BL (36) is calculated by the average top length TL (35) minus the average horizontal end slope length. The average horizontal end slope length is the (horizontal end slope lengths from flags 7 to 2 + 5 to 12 + 8 to 3 + 4 to 11) divided by 2.
In Step D, determine the weighted depth Dw (37). This is accomplished by using the grade rod (29) and subtracting the average rod top readings for Step (B1) or Step (B2). Dw = (29) (32) for Step (B2), or Dw = (29) (16) for Step (B1).
Top area of restored dugout TL** (35) times TW** (33) = AT (38).
Bottom area of restored dugout BL** (36) times BW** (34) = AB (39).
Four times the mid area equals the sum of TL** (35) + BL** (36) times the sum of TW** (33) + BW** (34) equals (40).
Sum of Areas equals the sum of the top area, the bottom area, and four times the mid area.
The volume of the restored pond in cubic yards equals the weighted depth Dw (37) times the sum of the areas (41) divided by 162.
The volume of materials in cubic yards removed in the dugout cleanout is the existing pond volume (28) subtracted from the restored pond volume (42) which equals the cubic yards removed (43).
