Methods of aquifer test analysis
Method

Description

matching

matching
observation graphs consists in solving direct or inverse problems
to estimate hydraulic parameters, followed by visual comparison of
observation and calculation curves. Inverse problem is solved
either by UCODE program or by least square
method

straightline

straightline
method is based on transformation of analytic dependences to
straightline equations; for steadystate solutions horizontal line
is used

typeline

In typeline
method logarithms both of initial analytical dependence and of
argument of special function involved in this analytical dependence
are taken

bisecting
line

In method of bisecting
line a graph of ratio of observed drawdown values in the first
observation well to that in the second observation well versus
ratio of corresponding calculated values is plotted. The better
hydraulic parameters are estimated, the nearer does the graph
approach to the bisecting line

In the column
"Method" short names of methods are given, these being used in
descriptions of the methods in other sections of help
system.
