The average K for the groundwater model was estimated at 1 m/
day using data generated from ten pumping tests. Groundwater
levels dropped approximately 3.5e5 m or about 17e25% of the
assumed depth of the aquifer from the apex of the rainy season to
the end of the hot season. Originally, twelve tests were run, but
because of large errors that occurred during two of the pumping
tests, only ten tests were included in the analysis. The maximum
error for all ten tests was estimated to be 20%. Error estimates were
calculated from the estimated amount of water that was lost
between the well and the collection buckets and the error associated
with estimating K using near constant pumping rates. Fig. 5
displays the K for each pumping test that was estimated using
the PapadopouloseCooper analysis method for recovery curves.
The estimated K values were between the typical values for the soil
types found in this area (Davis and Lambert, 2002).
