The variation characteristics of aquifer parameters,induced by groundwater source heat pump(GWSHP) operation under variable flow,were theoretically analyzed through a case study,in which the characteristics of building air conditioning load were *** results,compared with the constant flow operation,indicate that the influence on the variations of porosity,hydraulic conductivity and confined water head is decreased by 48%,51% and 71%,respectively,under variable flow *** security of variable flow operation is superior to that of constant *** is also concluded that the climate region and function of the buildings are primary factors which affect the suitability of variable flow operation in GWSHP.

To meet the growing demand for socioeconomic development,a large amount of groundwater is extracted from confined aquifers *** North China Plain has experienced considerable groundwater depletion and subsidence during the past six *** this study,we use Sentinel-1A/B SAR images from 2015 to 2020 to map the ground subsidence of the Tianjin–Langfang *** subsiding zones centered at Guangyang,Wuqing–Bazhou,and Jinghai are identified with maximum subsidence rates of 98.1,121.8,and 104.7 mm/*** and long-term signals are separated from time series subsidence and hydraulic measurements using continuous wavelet transform to retrieve aquifer *** long-term subsidence,which fits well with an exponential decaying model,remarkably slows down in our study *** elastic skeletal storage coefficients range between 0.52×10−3 and 9.66×10−*** then retrieve the spatial–temporal variations of total groundwater storage,recoverable groundwater storage,and irreversible groundwater *** storage depletion rates are apparently reducing,which benefits from the operation of the South-to-North Water Transfer Project and local groundwater management practices.
