We present preliminary results on the Dalitz plot analysis of $B^0
\rightarrow K^+ \pi^- \pi^0$ decays. The data sample comprises 213 
million $\Upsilon(4S) \rightarrow B {\overline B}$ decays collected 
with the BaBar detector 
at the PEP-II asymmetric-energy $B$~Factory at SLAC. We report 
measurements of the inclusive branching fraction, quasi-two-body 
fractions and $CP$-violating 
charge asymmetries for intermediate states including 
$K^*(892)^+ \pi^-$ and $\rho(770)^- K^+$. Observations of $B^0$ decays 
to the $K\pi$ $S$-wave intermediate states, $K_0^*(1430)^+ \pi^-$ and 
$K_0^*(1430)^0 \pi^0$, are reported. 
Evidence of the decay $B^0 \rightarrow K^*(892)^0 \pi^0$ is seen.
We set upper limits at 90\% confidence level on branching fractions of 
the nonresonant and other less significant intermediate states.
