The name of the reservoir hydrology record is a primary key referenced by the foreign key in . All names in the hydrology.res file must be unique.

The year specified here must be within the simulation period. If 0 is input for yr_op and , the model assumes the reservoir is in operation at the beginning of the simulation.

If 0 is input for and mon_op, the model assumes the reservoir is in operation at the beginning of the simulation.

For SWAT+ to calculate the reservoir surface area each day, the surface area at two different water volumes must be defined. Variables referring to the principal spillway can be thought of as variables referring to the normal reservoir storage volume, while variables referring to the emergency spillway can be thought of as variables referring to the maximum reservoir storage volume.

If shp_co1 is set to 0, the model will estimate this value.

If shp_co2 is set to 0, the model will estimate this value.

If seepage occurs in the reservoir, the hydraulic conductivity must be set to a value other than 0.
