There has been a longstanding need for improved equipment and methods for compacting soil on canal side slopes to control seepage. The prevailing current method of constructing thick compacted soil (earth) lining built up in horizontal layers by increasingly large conventional earthmoving and compaction equipment sometimes results in excessive canal excavation with more processed soil and a greater thickness of lining than are often necessary. In some cases, placement of thinner soil linings with layers parallel to the side slopes would be adequate to control seepage and be more economical than the conventional thick linings, provided equipment better adapted for this purpose was available. Also, there are many existing unlined canals worldwide where seepage has developed and compaction of soils in place could provide significant seepage reduction to conserve water and minimize damage to adjacent agricultural land. Furthermore, recent instances of sloughing of protective soil cover on plastic canal linings and on linings of soil subject to erosion indicate the possible need for compacting cover materials on side slopes. Following a brief description of soil linings, this report presents results of a survey of representative construction equipment manufacturers and contractors to determine (1) current equipment available for canal side slope compaction and (2) the extent of interest in further development of such equipment, if needed, with the possibility of cooperative research with the Bureau of Reclamation.
