| Overdamped slug tests are the ones we commonly analyze
with techniques like the straight-line methods of Hvorslev (1951) and
Bouwer and Rice (1976) or the type curve method of Cooper, Bredehoeft and
Papadopulos (1967).
AQTESOLV
makes application of the straight-line methods easier and more reliable
with recommended head ranges (Butler 2002) which help to overcome
ambiguity when data exhibit curvature. The recommended head ranges were
developed to improve the reliability of K estimates obtained with the
Hvorslev and Bouwer-Rice methods. |

AQTESOLV
features underdamped slug test solutions for both fully and
partially penetrating wells.
AQTESOLV
features an innovative visual curve matching tool that makes
parameter estimation for underdamped tests a snap!
AQTESOLV
also includes a correction for frictional well loss (Butler
2002) that is important for analyzing underdamped tests in small-diameter wells. |

AQTESOLV
includes methods that may be used to analyze multiwell slug tests
such as the KGS Model (Hyder et al. 1994) for confined and unconfined
aquifers. Most slug tests are conducted as single-well tests in which
heads (displacements) are measured in just the test (control) well. In a
multiwell slug test, heads are recorded in the test well and one or more
nearby observation wells. |
