Runoff Characteristics of Non-Point Source Pollutants (NPS) from Vinyl House Area

Unlike point source pollutants, non-point source pollutants (NPS) are discharged by rainfall. Because of seasonal and regional reason, it is very difficult to manage quantity of pollutants. Also runoff of non-point source pollutants is influenced by geological conditions, land use. Specially, non-point source pollutants of agriculture are difficult to understand characteristics of runoff and discharge irregular. Pollutant from agriculture area is a primary reason of polluting rivers and underground water. Because there isn't a facility that dealing with pollutants from agriculture area. That's why river pollution is increased. It is important to manage non-point source pollutants from agriculture area. According to type of corps, land use and cultivation method differ in agriculture area. So runoff characteristics of non-point source pollutants are different each other. Because of Basin area of the house area is covered with vinyl, rainfall runoff occurred quickly. Therefore it is important to consider runoff duration, runoff rate, runoff characteristics for monitoring vinyl house.
