Projected changes in streamflow, Coweeta Laboratory (North Carolina): 2070 — <br />2099 vs. 1961 — 1990. Winter = thick black line, spring = thin black line, summer = dotted <br />line, fall = dashed line. (Wu et al., 2014). <br />Stronger consensus is seen in the results presented by Bastola (2013) for the southeast region <br />(primarily Georgia and Florida), based on the latest climate model projections (CMIP5). These <br />results (Figure 3.18) show a clear majority of the utilized GCM simulations projecting small <br />increases in average spring and summer streamflow (on the order of 1 — 10 %) across a range of <br />models and representative concentration pathways (RCPs). Uncertainty is still evident, however, <br />as a number of projections indicate decreased flows in the future. <br />USACE Institute for Water Resources 34 January 9, 2015 <br />
