WebThe percolation test calculation is based on the time taken for the water level to fall from 75% to 25% capacity. This is done to avoid the possible outliers of the high seepage rates when the pit is full with a large head of water, and the low rates when the pit is empty with very little head of water.

WebJan 1, 2024 · Percolation is “the vertical flow of water to below the [rice] root zone”, and lateral seepage is the subsurface movement of water through the levees that border the rice fields (Bouman et al., 2007). While percolation and lateral seepage can be significant components of the rice field water balance, these subsurface flows are highly variable.
