Water levels in restored wetlands are often managed through pump drainage via an integrated network of open ditches. The aim of this thesis is to evaluate P dynamics in the sediment water component of a ditch that is managed to control the water level in a recently restored (from agriculture), seasonal wetland in south west England. Comparisons are made with a neighbouring agricultural ditch that lies in the same catchment. It was clear that pump drainage provided a source of P to the wetland ditch from the wetland, particularly in the dissolved form.
