Appendix C C-3GCM-Based Change Field Assessment and Hydrologic Modellingthe Percentile Method provides a very similar range using only 8 (or up to 10) scenarios. The scatter plot methodshows the extremes, but does not show a central tendency.Mean Monthly Recharge(mm/month)454035302520151050Scatter Plot Method - Mean Monthly Recharge per Scenario for Sandy SoilsJan Feb Mar Apr May Jun Jul Aug Sep Oct Nov DecFuture 11Future 29Future 31Future 50Base LineMean Monthly Recharge(mm/month)454035302520151050Percentiles Method - Mean Monthly Recharge per Scenario for Sandy SoilsJan Feb Mar Apr May Jun Jul Aug Sep Oct Nov DecFuture 21Future 22Future 35Future 38Future 40Future 48Future 53Future 54Base LineMean Monthly Recharge(mm/month)All 57 Future Climate Scenarios - Mean Monthly Recharge per Scenario for Sandy45Soils4035302520151050Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov DecFuture 1 Future 2Future 3 Future 4Future 5 Future 6Future 7 Future 8Future 9 Future 10Future 11 Future 12Future 13 Future 14Future 15 Future 16Future 17 Future 18Future 19 Future 20Future 21 Future 22Future 23 Future 24Future 25 Future 26Future 27 Future 28Future 29 Future 30Future 31 Future 32Future 33 Future 34Future 35 Future 36Future 37 Future 38Future 39 Future 40Future 41 Future 42Future 43 Future 44Future 45 Future 46Future 47 Future 48Future 49 Future 50Future 51 Future 52Future 53 Future 54Future 55 Future 56Future 57 Base LineFigure C.1 Mean Monthly Recharge for Sandy Soils computed using the Scatter Plot Method (top), the PercentileMethod (middle) and All Future Climates (bottom).
