Antecedent soil moisture is also an important index for the early warning of slope disaster. However, the availability of observed data is limited due to few monitoring stations for soil moisture in Taiwan. In view of the situation, estimating soil moisture through remote sensing data may be a practical way to obtain a wide range of soil moisture information. In this study, remote sensing data from MODIS was collected, and the Surface Energy Balance Alogrithm for Land (SEBAL) was applied for evaporative fraction calculation. The results are compared with the soil moisture observations from seven debris flow monitoring stations, which are established by the Soil and Water Conservation Bureau of Taiwan. The evaporative fraction is shown to positively correlate with soil moisture to some extent for the seven monitoring stations. ? 2021. All Rights Reserved. |
