Seasonal high water table definition

Seasonal high water table means the highest zone of soil or rock that is seasonally or permanently saturated by a perched or shallow water table. A planar surface, below which all pores in rock or soil (whether primary or secondary) that is seasonally or permanently saturated.
Seasonal high water table or "SHWT" means the highest level of the saturated zone in the soil during a year with normal rainfall. SHWT may be determined in the field through identification of redoximorphic features in the soil profile, monitoring of the water table elevation, or modeling of predicted groundwater elevations.
Seasonal high water table means the highest level that groundwater, at atmospheric pressure, reaches in the soil in most years. The seasonal high water table is usually detected by the mottling of the soil that results from mineral leaching.
