英文摘要: Abstract(#br)The limited number and duration of hydrological measurements in the East African Highlands inhibit current understanding of the impact of glacial recession on alpine riverflow. From historical records and surveys conducted in the dry season of 2005 and wet season of 2007, we report (1) recent changes in the terminal positions of large valley glaciers (Speke, Elena) and (2) spot measurements of alpine riverflow along altitudinal transects of the principal river (River Mubuku) draining alpine icefields in order to assess the relative contribution of icefields and underlying ecotones to river discharge. Observed acceleration in the rates of termini retreat of the Speke and Elena glaciers since the late 1960s is attributed, in part, to the convex–concave slope profile in which...
