<br />. <br /> <br />. <br /> <br />.. <br /> <br />GDJ371 <br /> <br />. hydrology "database": the database contains the natural flows (in 1 ODD's <br />of acre-feet) and the monthly salt loading values (in 1 ODD's of tons) for each of <br />the 29 hydrologic inflow points. These data are passed to CRSM via a binary <br />data file from MHYDRO. <br /> <br />. demand "database": the user supplies an ASCII demand input file to <br />SMDID which is processed and presented to CRSM in another ASCII file. For <br />each demand point, the annual diversion volume (in 1 OOO's of acre-feet) and <br />the annual depletion or consumptive use (in 1000's of acre-feet) are entered for <br />a certain year. Between yearly values entered, the user specifies to SMDID <br />whether the demands and depletions are to be held constant or linearly <br />ramped. The user also inputs the monthly distribution (in percent) for <br />disaggregation. The percentages must add to 100, but some may be negative <br />indicating that the diversion returns water in some months without taking water <br />in those months. The user may also specify the annual salt "pickup" (in ppm) <br />due to leaching or other direct salt additions. Note that this does not include <br />the concentrating effect of irrigation which is handled by CRSM. The salt <br />pickup may be negative, indicating that the diversion is a WQIP. The annual <br />salt pickup is disaggregated to monthly values using the monthly distribution for <br />demands and depletions; however this monthly distribution can be overridden <br />by data supplied to the model. <br /> <br />. CRSM: the user supplies data to the model via an ASCII control file. The <br />initial reservoir concentration (in mg/L) is input on the RESERV cards. The <br />monthly distribution of annual salt pickup for a return flow can be overidden by <br />inputting a monthly percent on the TONPCT cards. CRSM also allows for <br />modification of certain paramters during the course of the simulation via the <br />"transaction" cards. For diversions, the percent of water diverted which is <br />return flow, the allowable shortage percentage, the percent of return flow which <br />is returned to the river, and the TDS pickup (in ppm) can all be modified. <br /> <br />All initial values and input time series data to support the TDS methods will be <br />populated by the input DM!. <br />
