The volume of a reservoir is 2×107 m3, the catchment area is 500 km2, the average annual inflow of rivers and streams is 800 mm, and the annual silt entering the reservoir is 320 ton/km2, assuming that the proportion of silt is 1800 kg/m3, Assuming that the sand trapping rate of the reservoir is y, the ratio of the reservoir capacity to the annual inflow is x, and the relationship between the two is to try to estimate the number of years required for 80% of the initial reservoir capacity to fill up?
