• Loma Coal Hydrology
The hydrology for the Loma Coal Protect for Sheridan Enterprises
was generated using the Sot1 Conservation Service "Overland Flow Hydrographs"
method as assigned to mountainous terrain.
This methodology takes into account not only the immediate drainage
area, but all contributing basins. regardless of their specific influence
on the project site.
The mine entrance elevation was set, using the cumulative affect
of the computed Q's of both Lhe 100 and 500 storm frequency events.
