  We have developed a numerical model of flare heating due to the dissipation
of Alfv\'enic waves propagating from the corona to the chromosphere. With this
model, we present an investigation of the key parameters of these waves on the
energy transport, heating, and subsequent dynamics. For sufficiently high
frequencies and perpendicular wave numbers, the waves dissipate significantly
in the upper chromosphere, strongly heating it to flare temperatures. This
heating can then drive strong chromospheric evaporation, bringing hot and dense
plasma to the corona. We therefore find three important conclusions: (1)
Alfv\'enic waves, propagating from the corona to the chromosphere, are capable
of heating the upper chromosphere and the corona, (2) the atmospheric response
to heating due to the dissipation of Alfv\'enic waves can be strikingly similar
to heating by an electron beam, and (3) this heating can produce explosive
evaporation.
