From top to bottom represents measured flow, fraction of NO3–N (red) and other–N (green), and concentrations of N forms in residential runoff collected at 3-hour intervals over 56 sampling events from outflow pipe draining a residential catchment during an intensive sampling period of 1-week (June 16 to 23 2008).
