2015 Hammer Solute Tracer Injections

Observed in-stream timeseries of concentration for two whole-stream, pulse (aka slug) injections of uranine and resazurin in two reaches of the Hammer Stream (West Sussux, UK) with contrasting morphology (one sand bed, one gravel bed). In-stream monitoring includes background- and drift-corrected timeseries of uranine, resazurin, and resorufin collected at mulitple locations along the stream channel.

Sand-bed reach data are described and interpreted by:
