  We study the thermodynamics and non-relativistic hydrodynamics of the
holographic fluid on a finite cutoff surface in the Gauss-Bonnet gravity. It is
shown that the isentropic flow of the fluid is equivalent to a radial component
of gravitational field equations. We use the non-relativistic fluid expansion
method to study the Einstein-Maxwell-dilaton system with a negative
cosmological constant, and obtain the holographic incompressible forced
Navier-Stokes equations of the dual fluid at AdS boundary and at a finite
cutoff surface, respectively. The concrete forms of external forces are given.
