The evolution of the relativistic electron fluxes in the radiation belts can be described by the 3D modified Fokker-Planck equation in terms of radial distance, pitch-angle, and energy. Recently developed at UCLA, the VERB code models the dynamics of relativistic electrons subjected to ULF, ELF, and VLF waves including radial diffusion driven by PC4-5 waves; pitch-angle scattering by hiss, chorus, anthropogenic whistlers, lightning generated whistlers, and EMIC waves; and local acceleration driven by chorus waves. Numerical simulations are presented of a geomagnetic storm using the VERB code, coupled with RCM. Dynamics of the 10-100 keV electrons at L*=7 is inferred from RCM simulations and is used as a boundary condition for the VERB code for the radial diffusion operator. Numerical simulations are also presented of the sensitivity of radiation belt electron response to the seed population of electrons.
