<br />V. Description of Data and Software: South Platte Consumptive Use Model (SPCU) <br /> <br />Table 2: Water Budget Output from speD <br /> <br />Item Name Relationship Description <br />0 Carry-over Soil The Carry-over Soil Moisture from the previous month plus the Effective <br /> Moisture (Calculated at Rainfall to Soil Storage (L) plus Total Water Supplies for CU (I) minus <br /> the End of the Month) Irrigation Water Requirement (N). This value is calculated based on the <br /> following conditions: <br /> . If Carry-over Soil Moisture (0) is less than zero. then the value is <br /> set to zero. <br /> . If Carry-over Soil Moisture (0) is greater than zero but less than the <br /> MAX value, then it is the normal calculation (i.e. Carry over from <br /> prevo month + L + I - N). <br /> . If Carry-over Soil Moisture (0) is greater than MAX. then the value <br /> is set to MAX. <br />P Shortage [N -1-0] The shortage value is zero for scenarios where the groundwater is assumed <br /> to meet all remaining IWR past that met from surface supplies or soil <br /> moisture storage. If shortages are allowed. then the shortage is the Irrigation <br /> Water Requirement (N) minus Total Water Supplies (I) minus Carry-over Soil <br /> Moisture (0). <br />Q Depletion of Water [(0 - (Carry-over The Carry-over Soil Moisture (0) minus the carry-over storage from the <br /> Supplies from Previous previous month plus the Effective Rainfall to Soil Storage (L) all added to <br /> Month + L)) + (N Irrigation Water Requirement (N) minus the Available Soil Moisture (i.e. <br /> - P)] Carry-over Soil Moisture (0) - Carry-over from Prevo Month + L). <br />R Additional Deep [1-0] This is the Total Water Supplies Available for CU (I) minus Depletion of <br /> Percolation and Runoff Water Supplies (Q). <br /> of Water Supplies <br />S Total Deep Percolation IE + H + R] Surface Water Deep Percolation and Runoff (E) plus Well Water Deep <br /> and Runoff of Water Percolation and runoff (H) plus Additional Deep Percolation and Runoff of <br /> Supplies Water Supplies (R). <br />T Depletion Met by Amount of surface water used to meet the IWR and to refill the soil moisture <br /> Surface Water (if applicable). <br />U Depletion met by Amount of well pumping used to meet the IWR and refill the soil moisture in <br /> Groundwater the case when well pumping is specified. If well pumping is not specified <br /> then this represents the amount of water required to meet the IWR for a <br /> month after all the surface water available for CU that has been allocated <br /> and all the soil moisture used (if applicable). <br /> <br />Completion Report: South Platte Mapping and Analysis Program <br /> <br />25 <br />
