Estimates of Consumptive Use and Ground-Water Return Flow and the Effect ofRising and Sustained High River Stage on the Method of Estimation in Cibola Valley, Arizona and California, 1983 and 1984

摘要

The report describes that part of the study in which consumptive use byvegetation (crops and phreatophytes) and ground-water return flow in Cibola Valley were estimated for calendar years 1983 and 1984 using a modified version of the methodology described by Owen-Joyce (1984). Included in the report are (1) a brief description of the hydrologic system, (2) estimates of evapotranspiration, (3) estimates of ground-water return flow, (4) estimates of change in ground-water storage caused by rising and sustained high river stage, and (5) the effects of rising and sustained high river stage on the estimation of consumptive use by vegetation and ground-water return flow. All annual data values given in the report are for calendar years.
