Show Utah Geological and Mineralogical Survey, Water- Resources Bulletin 14, 1970 actual rate of movement from north to south may be greater than that observed. 5. The results of the tracer study do not permit determination of the absolute ratio of northward to southward discharge. The fill is not homogeneous, and the position or shape of the interface between the northward and southward flowing water could not be determined. Although an average rate of movement could be estimated, the actual discharge areas on either side could not be determined; thus a calculation could not be made of actual quantities of discharge. The tracer study, however, did yield enough information to allow an estimate of the probable range of permeability of the fill. This information will be of value if an analysis is made of a model of the causeway. 6. Additional, more reliable, information could be obtained from subsequent tracer studies if injections of dye could be made directly into the fill through wells. 35 |
