Fig. 5. Effluent concentrations of soluble reactive phosphorus (SRP) versus time showing the sequence of water flow paths in Flumes 1 and 2. Experiments at (a) 6°C and (b) 25°C. During flow stabilization periods, flow was set to inflow port at the top of the flume to outflow port at the top of the flume (It 
Ot). Single dashed lines indicate beginning of new flow path configuration. Hashed lines indicate small flow stabilization period during installation or removal of rainfall simulator. Open symbols are averages of two observations, indicated by small vertical or horizontal lines.
