Using an eikonal QCD-based model in order to connect the semihard parton-level dynamics to the hadron-hadron scattering, we obtain predictions for the $pp$ and $\bar{p}p$ total cross sections, $\sigma_{tot}^{pp,\bar{p}p}$, and the ratios of the real to imaginary part of the forward scattering amplitude, $\rho^{pp,\bar{p}p}$. We consider the phenomenological implications of a class of energy-dependent form factors in the high-energy behavior of the forward amplitude. Our results are consistent with the recent data from the TOTEM experiment.
