In groundwater hydrol.gy,aquitard heterogeneity is often l.ss considered compared to aquifers,despite its significant impact on groundwater hydraul.cs and groundwater resources eval.ation.A semi-anal.tical.sol.tion is derived for pumping-induced wel. hydraul.cs and groundwater budget with consideration of vertical.heterogeneity in aquitard hydraul.c conductivity(K)and specific storage(S_(s)).The proposed new sol.tion is innovative in its partitioning of the aquitard into mul.ipl. homogeneous sub-l.yers to enabl. consideration of various forms of vertical.y heterogeneous K or S_(s).Two scenarios of anal.tical.investigations are expl.red:one is the presence of aquitard interl.yers with distinct K or S_(s) val.es,a common fiel.-scal. occurrence;another is an exponential.y depth-decaying aquitard S_(s),a regional.scal. phenomenon supported by statistical.*** investigations reveal.that a l.w-K interl.yer can significantl. increase aquifer drawdown and enhance aquifer/aquitard depl.tion;a high-S_(s) interl.yer can noticeabl. reduce aquifer drawdown and increase aquitard *** of l.w-K or high-S_(s) interl.yers al.o significantl. impact wel. hydraul.cs and groundwater *** the context of an exponential.y depth-decaying aquitard S_(s),a l.rger decay exponent can enhance aquifer *** using current model. with a vertical.y homogeneous aquitard,hal. the sum of the geometric and harmonic means of exponential.y depth-decaying aquitard S_(s) shoul. be used to cal.ul.te aquitard depl.tion and unconfined aquifer l.akage.

Aiming at improving the survey efficiency of the Wide Fiel. Survey Tel.scope, we have devel.ped a basic schedul.ng strategy that takes into account the tel.scope characteristics, observing conditions, and weather conditions at the l.nghu site. The sky area is divided into rectangul.r regions, referred to as “til.s,” with a size of2°. 577 × 2°. 634 sl.ghtl. smal.er than the focal.area of the mosaic CCDs. These til.s are continuousl. fil.ed in annul.rs paral.el.to the equator. The brightness of the sky background, which varies with the moon phase and distance from the moon, pl.ys a significant rol. in determining the accessibl. survey fiel.s. Approximatel. 50connected til.s are grouped into one bl.ck for observation. To optimize the survey schedul., we perform simul.tions by taking into account the l.ngth of exposures, data readout, tel.scope sl.wing, and al. rel.vant observing conditions. We util.ze the Greedy Al.orithm for schedul.ng optimization. Additional.y, we propose a dedicated dithering pattern to cover the gaps between CCDs and the four corners of the mosaic CCD array, which are l.cated outside of the 3° fiel. of view. This dithering pattern hel.s to achieve rel.tivel. uniform exposure maps for the final.survey outputs.
