How Well Does Your Irrigation Canal Hold Water?, Robert Hill
How Well Does Your Irrigation Canal Hold Water?, Robert Hill
All Current Publications
Irrigation canals placed in native soil or lined with earth can have seepage water losses varying from 20 percent to more than 50 percent. Well designed, new compacted earth lined canals can have reduced seepage losses similar to concrete lined channels. However, consistent and regular maintenance is required to keep seepage losses low. Older concrete lined canals with deteriorated joints and frost heave or settled sections may also have high seepage losses and require rehabilitating.

In groundwater ecosystems, in situ primary production is low, and metabolism depends on organic matter inputs from other regions of the catchment. Heterotrophic metabolism and biogeochemistry in the floodplain groundwater of a headwater catchment (Rio Calaveras, New Mexico, USA) were examined to address the following questions: (1) How do groundwater metabolism and biogeochemistry vary spatially and temporally? (2) What factors influence groundwater metabolism? (3) What is the energy source for groundwater metabolism?
At Rio Calaveras, surface discharge and water table elevation increased at the onset of spring snowmelt. Groundwater biogeochemical changes in response to snowmelt included increases in dissolved oxygen …
