The amplification of interplanetary Alfven waves by
the passage of energetic protons accelerated in flares and traveling
interplanetary shocks has profound effect on the evolution of the elemental
abundances of solar energetic particles at the earth's orbit. We present a
model of coupled wave-particle evolution which includes focusing,
pitch-angle scattering, solar-wind convection, adiabatic deceleration,
wave transport and amplification by streaming protons. A comparison is made
of the model results for (a) a fixed source on the sun and (b) a source
associated with a traveling interplanetary shock.
