Trends in Timing, Magnitude, and Duration of Summer and Fall/Winter Streamflows for Unregulated Coastal River Basins in Maine During the 20th Century Scientific investigations rept

摘要

The purpose of this report is to specifically address the hypothesis that because winter/spring high streamflows appear to be occurring earlier in coastal Maine, base flow recessions could also be occurring earlier, resulting in a trend toward earlier, and possibly lower, longer lasting, summer low streamflows. This report presents the data and methods used to determine whether there are trends in the timing and (or) amount of streamflow during the summer and fall/winter for coastal river basins in Maine and whether these streamflow conditions are interseasonally correlated. The trend and correlation results presented in this report quantify whether seasonal changes observed in winter-spring hydrology relate to changes in summer low streamflows. The report also presents the data, methods, and results of correlation tests between seasonal streamflow statistics and meteorological data.
