Description:
The relation between surface water and groundwater must be considered when defining the hydrogeological characteristics' of a basin. The purpose of this thesis is to characterize the surface-groundwater relation at the University of Idaho Groundwater Research Site (UIGRS), in the Pullman-Moscow basin, Washington and Idaho. Eighteen wells at the UIGRS; six wells are completed in alluvial sediments and broken basalts, and twelve at different depths and fracture zones in the Wanapum basalt. Two main fracture zones define two aquifers: theE-fractured and theW-fractured basalt aquifers. The surface-groundwater relation was defined by using qualitative analysis. The methodology used in this analysis was the interpretation of the water changes throughout a four-year period and on specific events using hydrographs of stream stage and groundwater levels, as well as precipitation. The water level of the creek and the shallow and E-fractured basalt aquifer wells followed the same fluctuation pattern, whereas theW-fractured aquifer wells behaved in a different manner. The difference may be related to the barometric effect' and/or to different sources of recharge. The character of the fluctuation for the shallow and Efractured aquifer was defined by the distance from the creek and by the intensity and distribution of precipitation. During the summer and early fall, as well as often during maximum streamflow events, Paradise Creek may recharge the shallow and E-fractured basalt aquifers. The main source of water may be direct precipitation throughout the rest of the year. It is suggested that continuous data recording and chemical data analyses would contribute valuable additional information about the recharge and discharge mechanisms of the Pullman-Moscow basin.
