I received the plans and have been over them. I believe additional information will be needed but will try to do a preliminary analysis without any new survey info. I have establised the drainage basin area contributing to the dam using the Knox County GIS Information but have not determined the exact area. I am still learning how to use the County's GIS software. Have also looked at soil data but I am still quite a ways away from beginning calculations. I will contact you again in about a month when I finish the current project I am working on. It shoul be in the second week of July.
Questions that remain relate to:
1. Size of pipe and materials used for both the vertical drop and the hoirzontal leg.
2. I believe the spillway is a morningglory design. I will need an accurate set of dimensions for calculations and wherther or not
anti-vortexing provisions were incorporated. at the inlet. If anti-votexing was incorporated, then details on arrangement are also
needed.
3. Has the dam ever been over topped? If so by what depth of flow? If it hasn't, then how close has it come?
If you have further information on the above please send.
Very best regards,
Dennis
