<br />. <br /> <br />. <br /> <br />. <br /> <br />00J373 <br /> <br />Appendix A <br /> <br />Subroutines used in CRSM to compute salinity concentration <br /> <br />The main module calls the following subroutines after the hydrologic mass balance <br />has been computed for the entire system: <br /> <br />. RSAL T: the main routine for routing salt through the system. It is called <br />each time step after the hydrologic mass balance is done by HYDRBAL. The <br />routine loops over all nodes in the system (CRSS reaches) and all sequence <br />points (diversion points, inflow and return flow points, and reservoirs) in each <br />reach, computing the salinity concentration for each point in the river system. <br />This routine calls subroutines RETURN and RESOAL to compute the <br />concentration of return flows and reservoirs respectively. The routine also <br />computes the concentration for each hydrologic inflow point. <br /> <br />. RETURN: the routine to compute the salinity concentration of each return <br />flow. This routine accounts for the concentrating effect of irrigation on return <br />flows. The routine calls subroutine SAL TSUM to handle Water Ouality <br />Improvement Projects (WOIP's). <br /> <br />. RESOAL: the routine to compute the salinity concentration of a reservoir. <br /> <br />SAL TSUM: the routine to compute the amount of salt that can be removed by <br />a WOIP. If the WOIP can remove more salt mass than is currently in the river, <br />the difference is accumulated and removed at a later time if necessary. <br /> <br />. FLOWHT: the routine to accumulate salt mass and flow at selected points for <br />computing a flow-weighted average salt concentration at the end of each year <br /> <br />PRNFLOW: the routine used to print the annual flow and salt mass tables <br /> <br />CHMIT: a routine written to store lagged return flows and salt concentrations <br />and return them to the river at the end of the lagging period. This routine is not <br />used as lagged return flows were never tested in the system. <br /> <br />Input of salinity data to CRSS <br /> <br />CRSS is comprised of 4 main modules: <br />the hydrology "database" and management system (MHYDRO) <br />the demand "database" and management system (SMDID) <br />the actual model (CRSM) <br />the output system (TAPEDIT) <br /> <br />Data necessary for the modeling of salinity are input to CRSS in a variety of places. <br />These are: <br />
