The pro- <br />gram is one dimensional and is used to evaluate the vertical stratification <br />for up to 18 physical chemical and biological parameters. <br />This program is intended to interface on input (from upstream analysis) and out <br />put (for downstream analysis) with both the Stream Hydraulics and the Stream <br />Water Quality computer programs. The three programs together are referred to <br />as the Water Quality for River-Reservoir Systems Model (WQRRS). <br />8. ....oaR,... '''C'I'ICATIOIlI <br />The program is written in FORTRAN IV. Dimensions allow for 100 horizontal <br />layers in the reservoir, 10 discharge levels, and 10 inflow tributaries. <br />There are no dimensional limits on the number to reservoirs which can be <br />analyzed. Specifications for the computation, input and output intervals <br />must equal or exceed one hour. <br />c. ..T HOO& <br />The density of the water in each horizontal layer is a function of temperature, <br />which is determined by a basic energy budget computation, and the organic and <br />inorganic solid concentrations. Inflows are brought into the reservoir at <br />their respective density levels and the associated quality parameters are <br />distributed vertically by advection, diffusion and settling where appropriate. <br />All reaction rates are adjusted based on the calculated temperatures. <br />D. .QUINIENT DCT AILS <br />The program is operational on the CDC 7600 and the UNIVAC 1108 but may be used <br />on other high speed computers with minor modifications. The program requires <br />51K words of storage on the CDC 7600. Program input options allow the user to <br />specify input-output unit numbers. In addition to these units, unit numbers 5, <br />6 and 7 are reserved for the card reader, line printer and card punch respect- <br />ively. <br />Il. IlInI" ""'"' , <br />Cards are used for general input information but either cards or magnetic tape <br />can be used for data transfer from previous runs made for other upstream <br />reservoirs or tributary rivers. The printer is used for general output infor- <br />mation but either cards or magnetic tape can be used for data transfer to down- <br />stream reservoirs or river channels in a system analysis. <br />'0 ADDITIONAL .....A..a <br />Correct application of this program requires interdisciplinary technical <br />expertise. The output should be carefully evaluated by technical personnel <br />with training in hydrologic engineering and aquatic chemistry and biology. <br />National Weather Service (NWS) data is readily available from Ashvi1le, NC in <br />format CD144. A separate utility program is available from the HEC for con- <br />verting the NWS data to the standard formats of this program. <br /> <br />~:;'Oll: 2883 <br /> <br />......IOU. aDITION. Alt.
