Alteration of natural hydrologic regimes is a consistent and pervasive effect of urbanization on stream ecosystems. … Webthe peak flow and the duration of surface runoff. Storm direction has the greatest effect on elongated basins. On these basins, storms that move upstream tend to produce lower peaks of a longer duration than storms that move downstream. Method of Base flow separation There are three methods for base flow separation that are in common use.
