In this paper, the behavior of flood induced particulate nutrients (nitrogen and phosphorus) in lake Kasumigaura based on field survey was discussed.
The results obtained was as follows.
(1) 70% of total particulate loading settled before the flood finished. After 5days, the quantity of suspended nutrients in lake was approximatly 3-4% of total loading induced by flood.
(2) Settling velocity of flood induced particulate soild was about 1 (m/day) except for flood peried.
