However, due to the widespread variability in soils -- including areas with significant gravel content, soil stratification and a shallow, temporarily perched water table (particularly in March and April) -- we achieved a depth of 54 inches (137 centimeters) for only 22 of the 32 tubes.

These little springs are coming from a strange geological feature known as a perched water table, where an impervious layer of rock forms a saucer underground that eventually overflows.

Talking can often resolve tricky issues

Runoff usually occurs either when the infiltration rate is less than the rainfall intensity (classical Hortonian runoff), or when the soil saturates due to either the true ground water table or a perched water table rising to the surface.
