  "description": "We study the relation between surface infiltration and groundwater\nrecharge during managed aquifer recharge (MAR) with desalinated seawater in\nan infiltration pond, at the Menashe site that overlies the northern part of\nthe Israeli Coastal Aquifer. We monitor infiltration dynamics at multiple\nscales (up to the scale of the entire pond) by measuring the ponding depth,\nsediment water content and groundwater levels, using pressure sensors,\nsingle-ring infiltrometers, soil sensors, and observation wells. During a\nmonth (January\u00a02015) of continuous intensive MAR\n(2.45\u202f\u2009\u00d7\u2009\u202f10<sup>6</sup>\u202fm<sup>3</sup> discharged to a 10.7\u202fha area),\ngroundwater level has risen by 17\u202fm attaining full connection with the pond,\nwhile average infiltration rates declined by almost 2 orders of magnitude\n(from \u2009\u223c\u2009\u202f11 to \u2009\u223c\u2009\u202f0.4\u202fm\u202fd<sup>\u22121</sup>). This reduction can be\nexplained solely by the lithology of the unsaturated zone that includes\nrelatively low-permeability sediments. Clogging processes at the pond-surface\n\u2013 abundant in many MAR operations \u2013 are negated by the high-quality\ndesalinated seawater (turbidity \u2009\u223c\u2009\u202f0.2\u202fNTU, total dissolved solids\n\u2009\u223c\u2009\u202f120\u202fmg\u202fL<sup>\u22121</sup>) or negligible compared to the low-permeability\nlayers. Recharge during infiltration was estimated reasonably well by simple\nanalytical models, whereas a numerical model was used for estimating\ngroundwater recharge after the end of infiltration. It was found that a\ncalibrated numerical model with a one-dimensional representative sediment\nprofile is able to capture MAR dynamics, including temporal reduction of\ninfiltration rates, drainage and groundwater recharge. Measured infiltration\nrates of an independent MAR event (January\u00a02016) fitted well to those\ncalculated by the calibrated numerical model, showing the model validity. The\nsuccessful quantification methodologies of the temporal groundwater recharge\nare useful for MAR practitioners and can serve as an input for groundwater\nflow models.",
