Alfven wave turbulence is considered as the source of the non-thermal line broadenings observed in soft X-rays in solar flares. The waves are assumed to lose energy to particle acceleration and the temporal development for the case of Fermi acceleration, W(k) about k exp -2, is investigated. The decay of the wave energy density is compared to that of the nonthermal velocity for the event of 1980 June 29. The wave energy densities required to explain the degree of nonthermal broadening and its temporal characteristics are consistent with those typically inferred from gamma-ray observations. A relationship between the degree of nonthermal broadening and gamma-ray fluxes is predicted. In general, the larger the gamma-ray flux the shorter the time scales for the decay of the wave energy.
