AbstractA thorough understanding of recharge is usually a prerequisite for effective groundwater management.
The recharge regime remains unrevealed in the piedmont plain of the North China Plain, where is considered
as the main recharge zone of the Quaternary aquifer. To characterize the recharge regime, a case
study is presented in the piedmont plain of the Beiyishui River Watershed. The piedmont plain consists of
proluvial fan and alluvial fan/plain, and groundwater quality in the two parts is distinct. Total dissolved
solids and isotopic compositions are higher in the groundwater of proluvial fan than the groundwater of
the alluvial fan/plain. Local precipitation only recharges the groundwater in the proluvial fan. Fracture
water ascending along a buried normal fault and lateral inflow from the proluvial fan feed the unconfined
aquifer in the alluvial fan/plain. The runoff of the Beiyishui River seeps in the streambed of upper reaches
and then overflows seasonally in middle reach. The recharge from middle reach to the aquifer is negligible.
In addition, the fracture water originates from precipitation in the mountainous area with an average
elevation about 500 m and discharges to the overlaying aquifer. The contribution of fracture water to the
aquifer was estimated to be 77.9% in the alluvial fan/plain area. Due to the mixture in the aquifer, major
ions leached from soil of the proluvial fan are diluted and the hydrochemical pattern is changed from
CaMg–HCO3SO4 to CaMg–HCO3. It is considered that fracture water is the major recharge source of
the unconfined aquifer and the variation of precipitation in mountainous area would primarily affect
the recharge. This paper also shows the hydrological efficiency of buried normal fault as preferential flow.
