Fischbach2 <br /> <br />The variability and scope of irrigation practices in the Blue <br />River Basin and lack of time, personnel and funds prohibited the <br />gathering of actual data on specific management items. However, <br />using research data and certain estimates known about irrigation <br />management practices 1n the area allows discussion of potential <br />water saving. <br /> <br />Land shapi~6 practices have been neglected in this report in <br />anticipation of this information being available in other sections. <br /> <br />Crop irrigation is a consumptive and a necessary use of water <br />in Nebraska. Agriculture is the largest consumer of water. There- <br />fore, all management factors mentioned in this paper, if economi- <br />cally feasible, should be put into use to conserve water resources. <br /> <br />to: <br /> <br />Three sections of the report discuss irrigation water relation <br /> <br />HA TER LOSSES <br /> <br />Runoff, surface irrigation <br />Runoff, sprinkler irrigation <br />Evaporation <br />Deep Percolation <br /> <br />\iA TER USES <br /> <br />POTEllTLL \'Irl TER S"VING <br /> <br />lExtension Water Resources Specialist, Associate Professur <br />Agricultural Engineering Department, University of Ncbr~gka <br /> <br />2Extension Irrigationist, Associate Professor <br />Agricultural Engineering Department, University of Uebraska <br />
