For analysis purposes, it is assumed that drawdown is very fast, and no drainage occurs in materials with low permeability; thus the term “sudden” drawdown. Materials with values of permeability greater than 10-4 cm/sec can be assumed to drain during drawdown, and drained strengths are used for these materials." <ref> https...")
