The rainfall gauge of the station or the rainfall gauge set by the station is used for runoff observation. The soil moisture content was measured by manual sampling and drying method. The coverage was measured manually and visually. </p>\n Runoff and sediment are observed manually by means of runoff bucket (pool). The soil moisture content was measured by manual sampling and drying method. The covering degree was measured by human eyes.\n
