Example of storm event flood in a suburban headwater stream (Burlington MA), showing how storm flood waters go over bankfull, deposit sand, and scour the riparian zone clear of leaf litter. Peak storm flow had occurred prior this picture being taken.
Long term data set of nitrogen exports from the watershed (1994-2009) compared to budget estimates of net inputs to the watershed indicate that more than 80% of estimated inputs are removed by watershed processes, but that this effectiveness declined in wetter years.
