Soil Water Balance: uses and methods
combines actual measurement points and daily weather to estimate root zone water deficit.
Applicable scope and calculation boundary
measuring point spatial map uses inverse distance weight interpolation; the daily forecast uses a simplified bucket model. Weather comes from user input, with no pretense of access to real-time forecasts.
model and reference method
Root zone water balance; IDW spatial interpolation.
model version: 1.0.0. The results are used for scientific research, exploration and teaching, please interpret according to the model conditions.
