Main objective of this study was to develop the models to estimate soil water content (WTR) and rainfall during four years in Andong with verification. Trigonometric function model (TFM), Fourier function model (FFM) and exponential function model (EFM) for soil water content (WTR) were developed. Gaussian function model (GFM) and sigmoid function model (SFM) for rainfall were developed. Amplitude of mean WTR from 10 cm to 50 cm was 12.64%. Range of periodicity according to period and soil depth was 660 days and 427 days, respectively. The deeper soil depth the shorter in WTR periodicity. Slope of accumulated rainfall change was the highest in 2009, the critical point was the earliest in 2011. Average RMSE of TFM, FFM, EFM, GFM and SFM was 1.352%, 1.356%, 2.117%, 21.37 mm and 27.09 mm, respectively, and average NSE was 0.696, 0.694, 0.857, 0.937 and 0.996, respectively. Four models (TFM, EFM, GFM and SFM) were deemed ｢very appropriate｣ and FFM was judged to be ｢appropriate｣ based on the criteria of error analysis.
