  1. Because w1 and w2 in equation 2:1.1.6 is fixed, add two variable to store these two coefficients to avoid repeating calculation.
  2. When w1 and w2 is calculated using equation 2:1.1.7 and 2:1.1.8, FC and SAT should be FC*rootdepth and SAT*rootdepth rather than (FC-WP)*rootdepth and (SAT-WP)*rootdepth. And the unit conversion of rootdepth would be from m to mm.
  3. Overload the function Calculate_CN to calculate the CN of one cell.
  4. Delete some parameters and input variables. They are Depre_in,Moist_in and Depression. D_SOMO from soil water balance module and D_DPST from depression module is enough. The initialization of soil moisture and depression storage is the task of soil water balance module and depression module.
  5. Modify the name of input and output variables to make it consistent with other modules.

  1. Add the support of dynamic multi-layers soil, rather than the fixed 2 layers in previous version. 2.The unit of soil depth and root depth (from crop.dat) are both mm.
