Ephemeral-stream channel and basin-floor infiltration and recharge in the Sierra Vista subwatershed of the Upper San Pedro basin, southeastern Arizona

Abstract

zone until it is vertically displaced by infiltrated water from subsequent streamflows and eventually recharges the regional aquifer. Ephemeral-stream channel infiltration during 2001 and 2002 was estimated to account for about 12 to 19 percent of the estimated average annual recharge in the Sierra Vista subwatershed.

Land cover controls on summer discharge and runoff solution chemistry of semi-arid urban catchments

“…In contrast, winter precipitation events are longer in duration, lower in intensity, spatially widespread, and evenly distributed. Winter rainfall accounts for most mountain front recharge in non-urban settings (Coes and Pool, 2007;Eastoe et al, 2004); however, a significant proportion of recharge occurs via stream channel infiltration of runoff generated in response to monsoonal rainfall (Baillie et al, 2007;Goodrich et al, 2004). Therefore, urban rainfall-runoff responses may significantly impact ephemeral channel recharge.…”

Hydrogeologic framework of the middle San Pedro watershed, southeastern Arizona

“…3, table 1) (Anderson and others, 1992) and has been described by several reports (Brown and others, 1966;Roeske and Werrell, 1973;Pool and Coes, 1999;Coes and Pool, 2007;Pool and Dickinson, 2007). Groundwater flows through the basin fill aquifer from recharge areas near the mountains to perennial reaches of the San Pedro River, where it discharges to the stream and is transpired by phreatophytes (Pool and Coes, 1999).…”

“…An extensive literature search of published and unpublished hydrogeologic information was used to develop initial conceptual models and identify data needs. Preexisting data are available from drill logs for about 1,350 wells, geophysical logs for 4 wells (Daniel Weber, Errol L. Montgomery & Associates, written commun., 2009), and from many regional geologic studies (Melton, 1965;Gray, 1967;Scarborough and Peirce, 1978;Shafiqullah and others, 1980;Drewes, 1981;Haynes, 1987;Menges and Pearthree, 1989;Scarborough, 1989;Dickinson, 1991;Hereford, 1993;Smith, 1994;Saltus and Jachens, 1995;Dickinson, 2003) and hydrogeologic studies (Brown and others, 1966;Freethey, 1982;Anderson and others, 1992;Jahnke, 1994;Corell and others, 1996;Pool and Coes, 1999;Goode and Maddock, 2000;Leenhouts and others, 2006;Coes and Pool, 2007;Pool and Dickinson, 2007).…”
