## IntegratedVelocity Solver

**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).
