Most of the rural wells (86%) were installed in glacial deposits with depths ranging from 12-90 ft (ISWS, 1935).
It should be noted that the number of wells in a section are probably underestimates, because well records were not required by law to be submitted to the ISWS until the 1960s, making well records between the years 1935 and the 1960s incomplete (Wilson et al., 2013).
ISWS records show that one of the remaining wells was sealed in 2005, but the location of the 5th well (north-center of the section) is presently cropland with no existing structures, suggesting that it was abandoned and filled at some point.
The wells that were likely associated with the former structures shown on older plat maps have presumably been abandoned and/or filled, but there is no record of sealing in the ISWS well records.
Laboratory experiment is an important approach to investigate the ISWs loading on cylinders.
Along with rapid development of computer and CFD technology, numerical methods have gotten more and more extensive application to investigate the loading induced by ISWs. The Morison empirical method , modal separation , and regression analyses  were applied to estimate the forces exerted by internal soliton on cylindrical piles.
Nevertheless, most researches before just focused on the cases of ISWs forces on an isolated cylindrical pile.
One of the most commonly used is the 24-hour 100-year storm, or a 1 percent chance that a storm of this duration will occur in Illinois in any year, according to Momcilo Markus, co-author and ISWS
As the ISWS continued to experiment with radar-based rainfall mapping, it became apparent that lack of knowledge of the distribution of raindrop diameters introduced major uncertainty into the interpretation of the radar data.
Two proposals to develop such a radar were independently submitted by both the ISWS and the University of Chicago.
While at ISWS, Lamb's research interests included studying the physical and dynamical processes responsible for climate and its seasonal-to-interannual-to-decadal-scale variations, particularly for regions in North America and Africa where the vital growing season rainfall is delivered by mesoscale weather systems.
In the early 1990s, when the ISWS began to divest itself of such advanced sensor platforms and to diminish its scope of research, Lamb realized that would make it difficult for him to accomplish cutting-edge research and maintain his international collaborations, so he began a new phase of leadership in Oklahoma.
