Abstract. It is commonly presumed that organic agriculture causes only minimal environmental pollution. In this study, we measured the quality of percolating water in vadose zone, underlying both and conventional intensive greenhouses. Our study was conducted newly established farms where subsurface greenhouses has been monitored continuously from their establishment. Surprisingly, relying on solid matter, such as composted manure implemented soil prior to planting sole fertilizer, resulted...
Scarcity of freshwater for agriculture has led to increased utilization treated wastewater (TWW), establishing it as a significant and reliable source irrigation water. However, years research indicate that if not managed adequately, TWW may deleteriously affect soil functioning plant productivity, pose hazard human environmental health. This review leverages the experience researchers, stakeholders, policymakers from Israel, United-States, Europe present holistic, multidisciplinary...

Abstract Detailed hydrologic models require high‐resolution spatial and temporal data. This study aims at improving the interpolation of daily precipitation for models. Different parameterizations (1) inverse distance weighted (IDW) (2) A local regression (LWR) method in which elevation is explanatory variable distance, difference aspect are weighting factors, were tested a hilly setting eastern Mediterranean, using 16 years The preferred IDW was better than LWR scheme 27 out 31 validation...
Understanding and predicting regional impacts of El Niño–Southern Oscillation (ENSO) Pacific Decadal (PDO) on winter (October–March) precipitation can provide valuable inputs to agricultural water resources managers. Effects ENSO PDO were assessed in 165 climate divisions throughout the southern United States. A continuous region significantly (P < 0.05) increased (decreased) response Niño (La Niña) conditions preceding summer (June–September Southern Index (SOI)) extends across entire...
Land use change from natural ecosystems to cropland influences groundwater recharge, including water quantity and quality. Soil core samples (0–11‐m depth) six boreholes beneath irrigated two ecosystems, in Vertisols, were analyzed for particle size distribution, content, water‐extractable Cl − Chloride mass balance numerical, one‐dimensional unsaturated flow transport modeling used assess average transient recharge fluxes test matrix vs. preferential hypotheses.

Abstract. Nitrate is considered the most common non-point pollutant in groundwater. It often attributed to agricultural management, when excess application of nitrogen fertilizer leaches below root zone and eventually transported as nitrate through unsaturated water table. A lag time years decades between processes occurring their final imprint on groundwater quality prevents proper decision-making land use groundwater-resource management. This study implemented vadose-zone monitoring system...
Abstract. We study the relation between surface infiltration and groundwater recharge during managed aquifer (MAR) with desalinated seawater in an pond, at Menashe site that overlies northern part of Israeli Coastal Aquifer. monitor dynamics multiple scales (up to scale entire pond) by measuring ponding depth, sediment water content levels, using pressure sensors, single-ring infiltrometers, soil observation wells. During a month (January 2015) continuous intensive MAR (2.45 × 106 m3...
Abstract Drywells, perforated above the water table, are an attractive tool for both reducing risk of floods, and increasing groundwater recharge in urban\suburban areas. Various simplifications relationship between injection discharge (Q) water‐level rise drywell during (H) available. This work presents observations models that improve our understanding performance, namely ratio Q/H injections varying time dynamics. The screen is at 22–27 m below surface sandy porous medium, where table 40...
Groundwater recharge is primarily influenced by land use and climate. Nevertheless, it the flow transport processes that take place in vadose zone ultimately control quantity quality of groundwater replenishment. Vadose monitoring systems (VMSs) were implemented under agricultural fields. The VMSs provided continuous information on both temporal variation water content chemical composition sediment pore at multiple depths deep (∼20 m). Models for vertical unsaturated chloride calibrated to...

Abstract Switching crop type and consequently changing irrigation fertilization regimes lead to alterations in deep percolation solute concentrations of pore water. Herein, observations from the vadose zone model simulations demonstrate changes water, chloride, nitrate fluxes under a commercial greenhouse following change tomato lettuce cropping. The site, located above phreatic aquifer, was monitored for 5 years. A vadose‐zone monitoring system implemented provided continuous data on both...
Abstract. Managed aquifer recharge (MAR) can be affected by many risks. Those risks are related to different technical and non-technical aspects of recharge, like water availability, quality, legislation, social issues, etc. Many other works have acknowledged this nature theoretically; however, their quantification definition has not been developed. In study, the risk performed means “fault trees” probabilistic assessment (PRA). We defined a fault tree with 65 basic events applicable...
Abstract We study geochemical processes along the variably‐saturated zone during managed aquifer recharge (MAR) with reverse‐osmosis desalinated seawater (DSW). The DSW, post‐treated at desalination plant by calcite dissolution (remineralization) to meet Israeli water quality standards, is recharged into Coastal Aquifer through an infiltration pond. Water monitoring two MAR events using suction cups and wells inside pond indicates that cation exchange dominant subsurface reaction, driven...
Abstract. Contamination of groundwater resources by nitrate leaching under agricultural land is probably the most troublesome agriculture-related water contamination worldwide. Contaminated areas often show large spatial variability concentration in wells. In this study, we tried to assess whether can be characterized on basis use and standard practices. Deep soil sampling (10 m) was used calibrate vertical flow nitrogen-transport numerical models unsaturated zone different uses. Vegetable...
Pollution of groundwater by nitrate originating from irrigated fields was considered for this study. We hypothesized that under cropped conditions, low-salinity irrigation water (e.g., desalinated water) could reduce leaching below the root zone, due to two possible mechanisms: (i) decreased vertical fluxes and (ii) increased nitrogen uptake plant roots chloride–nitrate competition. The main goal study investigate hypothesis. Considering a citrus grove, investigation relied on...
