  In this paper, we establish a connection between Rokhlin dimension and the
absorption of certain model actions on strongly self-absorbing C*-algebras.
Namely, as to be made precise in the paper, let $G$ be a well-behaved locally
compact group. If $\mathcal D$ is a strongly self-absorbing C*-algebra, and
$\alpha: G\curvearrowright A$ is an action on a separable, $\mathcal
D$-absorbing C*-algebra that has finite Rokhlin dimension with commuting
towers, then $\alpha$ tensorially absorbs every semi-strongly self-absorbing
$G$-actions on $\mathcal D$. This contains several existing results of similar
nature as special cases. We will in fact prove a more general version of this
theorem, which is intended for use in subsequent work. We will then discuss
some non-trivial applications. Most notably it is shown that for any $k\geq 1$
and on any strongly self-absorbing Kirchberg algebra, there exists a unique
$\mathbb R^k$-action having finite Rokhlin dimension with commuting towers up
to (very strong) cocycle conjugacy.
