The semimicroscopic particle-hole dispersive optical model is adopted for a description of main properties of isoscalar giant multipole resonances (up to $L=3$) in medium-heavy closed-shell nuclei. The main properties are characterized by the strength distribution, transition density, and partial and total probabilities of direct one-nucleon decay. The model is implemented to describe characteristics of the mentioned resonances in the ${}^{208}\mathrm{Pb}$ nucleus, taken as an example. Calculation results are compared with available experimental data.
