The presence of certain ions may cause a suppression or quenching of fluorescence (Smart and Laidlaw 1977). Large Losses of Rhodamine WT fluorescence were noted in the presence of sodium and potassium chloride, with loss increasing through time. However, the study of Bencala et aL (1983) showed little suppression in solutions containing lithium, sodium, potassium, strontium, chloride and nitrate. Dye adsorption is a more serious problem, although many studies assume that the tracer is conservative.

On the initial rising limb, phreatic conduit water of long residence time may be displaced by incoming water. This is replaced by a mix of phreatic and subcutaneous water as the main flood pulse comes through, characterized by higher conductivity and increasing turbidity. 5) raises turbidity bur has lower solute concentration (lower conductivity). This water dominates the early part of the recession but is supplanted by basetlow from subcutaneous and phreatic storage. The magnitude of each water type can be roughly estimated by integrating under the separated hydrograph.
