Application of steady state response ratios to the Snake River Plain Aquifer Item Info

Conjunctive management of surface and ground water is complicated by two basic physical phenomena: (1) effects of ground-water stress (pumping or recharge) propagate in all directions (assuming the aquifer is continuous in all directions), and (2) effects of aquifer stresses on surface water may be attenuated over periods of years or even decades. Response functions and ratios provide a means of understanding and mathematically quantifying spatial and temporal variation of aquifer pumping or recharge effects on surface water. Stream-aquifer response ratios, representing cause and effect relationships in steady state, have been developed for each active cell of the Snake River Plain aquifer model grid (SRPAM1.1). The response ratios for the 51 head dependent river cells representing the Snake River have been aggregated into six reaches bounded by gaging stations. Model cells representing the Snake River Plain aquifer have been grouped into 20 zones based on similarity of response function values to each of the six river reaches. Median steady state response ratios are provided for each zone for subsequent incorporation into integrated surface and ground-water models.
