===== IntegratedVelocity Solver =====

==== General Informations ====

  * **Solver Fortran File:** ''IntegratedVelocity.f90'' 
  * **Solver Name:** ''IntegratedVelocity'' 
  * **Required Output Variable(s):** ''Integrated Velocity'' (DIM-1)
  * **Required Input Variable(s):** A ''Flow Solution'' (given in ''Flow Solution Name''), ''Depth'' or ''Height'' 
  * **Optional Output Variable(s):** None
  * **Optional Input Variable(s):** None


==== General Description ====
This solver compute the mean vertically integrated horizontal velocities, either on the bedrock surface or on the upper surface. If the keyword ''Compute Flux'' is set to ''True'', the horizontal fluxes are computed else the mean horizontal velocities are computed (default).
