How are water table levels and seasonal changes in groundwater addressed in the hydrology analysis?
The flood mapping study is designed to determine surface flows in the South Boulder Creek floodplain and does not provide a detailed analysis of groundwater conditions. However, understanding general groundwater conditions and the level of anticipated ground saturation is important in determining flood water infiltration affecting flood runoff. The study reflects groundwater and soils conditions through the model calibration efforts. The model does not explicitly compute groundwater depths or changes in groundwater levels during a flood. Such level of resolution is not necessary to compute surface runoff during a flood.
