Based on this initial phase, it <br />was determined that in the Price River Basin 18 percent of the salinity <br />originates from the mountain runoff, 61 percent from the irrigated <br />agricultural area, and 21 percent from natural runoff in the desert rangeland <br />area. '!be results were similar for the San Rafael River Basin with 15, 60, <br />and 25 percent, respectively, coming from the mountains, agricultural area, <br />and desert rangeland. <br /> <br />Based on these results, the major emphasis of the field verification <br /> <br /> <br />activities was centered around the irrigated agricultural land use area. '!be <br /> <br /> <br />two river basins were divided into eight sub-basins and a plan formulated for <br /> <br /> <br />collecting data to construct water and salt balances around each sub-basin. <br /> <br /> <br />Between May 1982 and March 1983, the following types of data were collected. <br /> <br />- Streamflow and water quality data <br /> <br /> <br />- Irrigation canal diversion data <br /> <br /> <br />- Canal seepage measurements <br /> <br /> <br />- Ground water depth and quality data <br /> <br />I'll)' l' 6, I') <br />v \ ,'" '''"- <br /> <br />II-1 <br />
