      abstract = {Excerpts from the report:  Water is becoming one of the  Nation's most limiting resources.  In irrigation for  agriculture, conveyance losses and low application  efficiencies of water represent the principal source of  waste.  About one-third of all water diverted for  irrigation is lost from point of diversion to the farm.   Another third is lost through deep percolation and runoff  during application.  This leaves one-third of the water  diverted for irrigation available for plant growth and land  conditioning.  Both conveyance and application efficiencies  of irrigation water can be greatly improved.  Conveyance  losses are easier to  control, as canal management is  usually in the hands of trained people.  Watertight  conveyance structures almost completely eliminated losses.   Closed underground conduits are more efficient than open  channels, but in most instances conduits are more expensive  to construct than channels.  Linings also help to control  weeds and indirectly contribute to the solution of the  drainage problem.},
