Neutrino induced pion production in the resonance region is one of the most important interaction modes for the current and future generation long-baseline neutrino oscillation experiments. It is also sensitive to nuclear effects, including fermi motion, initial-state nucleon correlations, and final-state interactions \textit{etc.}, which affect event topology and energy reconstruction of resonance interactions, and contribute to the systematic uncertainty for oscillation measurements. We present study of the $\nu_{\mu}$ charge current interactions in the resonance region using high-statistics, high-resolution NOMAD data. Constraint on nuclear effects is also discussed.
