What is a static head measurement? Evaluating structural error and implications for regional groundwater modeling by Abrams, Daniel B., Cullen, Cecilia, Ghiami Shomami, Fereshteh

“…Most groundwater modelers avoid using static heads measured from active production wells because they can introduce a bias into model calibration. However, in…”
