If these values are not homo- <br /> <br />genous, the ground water outflows are in error and some <br /> <br />readjustment of the water budgets is necessary. Note <br /> <br />that hydraulic conductivity must also be corrected for <br /> <br />viscosity effects. <br /> <br />Subroutine SALT <br /> <br />The function of the SALT subroutine is to formulate the salt <br /> <br />budgets by multiplying the various item~ in the water budgets by the <br /> <br />appropriate salinity concentrations.
