the effect of raindrop impact and infiltration on the mixing process between surface runoff and tracer dye is a saturated porous medium (ottawa sand) was studied in the laboratory. experiments were conducted in a tilting plexiglass flume 10 cm wide, 200 cm long, and 30 cm deep. infiltration and rainfall rate and energy could be closely controlled, and the mixing process at the surface was easily observed. samples of pore fluid were obtained by withdrawing fluid through rubber septa with a microsyringe, and concentrations were measured by fluorometry. a complete description of the apparatus is presented, along with the results of 21 simulated rainstorm events (edited author abstract) 9 refs
