  Recently, there has been an increasing demand for deep imaging surveys to
investigate the history of the mass assembly of galaxies in detail by examining
the remnants of mergers and accretions, both of which have very low surface
brightness (LSB). In addition, the nature of star formation in LSB regions,
such as galaxy outer disks, is also an intriguing topic in terms of
understanding the physical mechanisms of disk evolution. To address these
issues, this study conducts a survey project, called the Korea Microlensing
Telescope Network (KMTNet) Nearby Galaxy Survey to construct a deep imaging
data set of nearby galaxies in the southern hemisphere using KMTNet. It
provides deep and wide-field images with a field-of-view of $\sim$12 deg$^2$
for 13 nearby galaxies drawn from the Carnegie-Irvine Galaxy Survey catalog, in
optical broadbands ($BRI$) and an H$\alpha$ narrowband. Through a dedicated
data reduction, the surface brightness limit in
10$^{\prime\prime}\times10^{\prime\prime}$ boxes was found to reach as deep as
$\mu_{1\sigma}\sim29$-31 mag arcsec$^{-2}$ in the optical broadbands and
$f_{1\sigma}\sim1$-$2\times 10^{-18}$ erg s$^{-1}$ cm$^{-2}$ arcsec$^{-2}$ in
the H$\alpha$ narrowband. To conclude the paper, several possible scientific
applications for this data set are described.
