    Researchers are not agreed on the effects of logging on lag time. Numerous studies have shown that the use of heavy equipment in logging operations can cause soil compaction. Also, associated roads alter natural drainage patterns by concentrating runoff and interrupting subsurface flow. As a result these researchers say, less infiltration into the soil takes place after treatment than in the undistrubed condition. In addition, the increased overland flow my be accelerated due to the development of waterways such as erosion rills or the removal of channel obstructions. A sorter lag time could then result.
