  • Catchment time of concentration

    Hi all,

    We are trying to find tools which will help us calculate catchment slope along the longest flow path, and the length of the longest flow path for hundreds of small catchments.  The catchments have been determined using ArcGIS, but we are having to do a lot of manual work to determine the longest flow path within each of the catchments.

    I'm sure there must be a tool out there which will do this, but all the one's we have seen don't quite measure up.

    Any ideas?

  • Mike 11 reservoirs and spillways

    Hi all,

    I am trying to represent an reservoir, dam and spillway that are located along a river.  Essentially I have a  storage elevation relationship for reservoir (no cross sections) and a Qh relationship for the spillway.

    Currently I am using the Regulating Structures, and the "Additional Storage Area" option in the Mike 11 cross section to represent the storage, but I feel that there may be a better way.

    One of the problems is that I do not have cross sections of the reservoir so the only way I was aware of to represent the storage is to use the "Additional Storage Area" option.  Any other ideas?
