Title: Field study of ephemeral stream-aquifer interaction
Abstract: Ephemeral streams, the Rio Puerco and Rio Salado, north of Socorro, NM, near Interstate-25 were instrumented to investigate infiltration and ground-water recharge due to channel seepage. Monitor wells, neutron access holes and stream stage recorders provided information to characterize the nature of stream aquifer interaction and to quantify recharge. The Rio Puerco has a relatively well-defined channel with a small width to depth ratio. The Rio Puerco flows in response to both winter and summer precipitation, as well as spring runoff. The stream carries a large suspended sediment load which results in the development of a clogging layer on the channel bottom. The Rio Salado has a large width-depth ratio and a braided channel filled mostly with permeable sand and gravel. The Rio Salado flows mostly in the summer in response to thunderstorms. Our results show that hydraulic connection to the underlying aquifer is highly variable on the Rio Puerco.
