The model development and verification for surface branch wood fuels moisture prediction after precipitation during spring period at the east coast region

In this study, we developed a fuel moisture variation prediction model on each day after precipitation during a spring forest fire exhibition period. For this research, we selected plots in pine forest on Sam-Chuck si and Dong-hae si in Kangwon do according to a forest density(low, mediate, high) and classified a surface woody fuel by a diameter.(below 0.6cm, <TEX>$0.6{\sim}3cm$</TEX>, <TEX>$3{\sim}6cm$</TEX>, and above 6cm). A validity of this model was verified by applying a fuel moisture variation after precipitation in this spring. In the result, <TEX>$R^2$</TEX> was <TEX>$0.76{\sim}0.92$</TEX>. This model will be a useful for improvement of a forest fire danger rate forcast through a prediction a fule moisture in forest.
