- Description:
- Investigation of the mechanics of water movement from irrigation canals to the water table has been performed on selected canals in southern Idaho. Field studies of existing seepage measurement techniques including ponding tests, inflow-outflow techniques and seepage meters were made. A new seepage meter which will operate efficiently in large operating canals was developed. An accurate and reliable tensiometer system for monitoring changes in soil moisture pressure beneath operating canals was developed. Measured decreases in soil moisture and pressure beneath an operating canal during the irrigation season indicated decreasing seepage rates caused by natural sealing of a thin soil layer on the canal bottom. A fast response, inexpensive null point tensiometer was laboratory tested and a device for measuring the capillary pressure - saturation curve for soils in situ was investigated. New techniques for obtaining and testing undisturbed soil cores using heat shrinkable tubing allow efficient laboratory determination of hydraulic characteristics.
