Summary:To clarify environments of road deposits, one of main non-point sources in urban area, we have already presented a new technique, named as a modeled storm-water sampling (MOS) technique, in which one can easily obtain road deposits under simulated rainy conditions. By using the MOS technique, we performed the field measurements for road-deposit environments in the watershed of the Oohori River which inflows into Lake Teganuma. In addition, we used a direct sampling (DS) technique with a brush to compare the observed results obtained with the MOS technique. The observed results indicate that the SS and water quality measured with the DS technique are much larger than those with the MOS technique. This result corresponds to the experimental data conducted by the authors. The differences of the road-deposit environments between the residential and industrial area are also discussed.
