  In this research article, we establish the geometrical bearing on Riemannian
submersions in terms of $\eta$-Ricci-Yamabe Soliton with the potential field
and giving the classification of any fiber of Riemannian submersion is an
$\eta$-Ricci-Yamabe soliton, $\eta$-Ricci soliton and $\eta$-Yamabe soliton. We
also discuss the various conditions for which the target manifold of Riemannian
submersion is an $\eta$-Ricci-Yamabe soliton, $\eta$-Ricci soliton,
$\eta$-Yamabe soliton and quasi-Yamabe soliton. In a particular case when the
potential filed $V$ of the $\eta$-Ricci-Yamabe soliton is of gradient type, we
derive a Laplacian equation and providing some examples of an
$\eta$-Ricci-Yamabe soliton on a Riemannian submersion. Finally, we study
harmonic aspect of $\eta$-Ricci-Yamabe soliton on Riemannian submersions and
mention geometrical and physical effects of Ricci-Yamabe solitons.
