A simple model is presented which interpolates between the DGLAP and BFKL regimes in deep inelastic ep scattering. This model is based on the CCFM and LDC models, and it is simple enough to provide an intuitive picture of the transition region between the two domains. Results are presented for both fixed and running coupling; for fixed coupling the transition between the domains occurs at a constant ratio between ln k⊥2 and ln 1/x, while for a running coupling it occurs for constant ratio between ln ln k⊥2 and ln 1/x.
