I like the passive voice, its how we were taught to write technical documents - saying "I did this" or, "we will show" sounds like a school essay about your summer holiday. Its about the science not the writer. Can see its becoming more common these days - maybe I am just old

They are called burst sweep cycles, the water is flowing over sand dunes on the river bed and as the current crosses the crest of the dune and expands and recirculates causing burst :-)
