Global groundwater depletion is a pressing issue, particularly in regions dependent on for agriculture. Agricultural Managed Aquifer Recharge (Ag-MAR), where farm fields are used as spreading grounds flood water, promising strategy to replenish groundwater, but it raises concerns about pesticide leaching into aquifers, posing risks both drinking water quality and ecosystems. This study employs physically based unsaturated flow model, Bayesian probabilistic approach novel towed transient...
Resolving the role of arid and hyper-arid regions in global carbon cycle their influence on atmospheric CO2 concentrations remains a significant challenge, both theoretically practically. Theoretical challenges stem from widespread underestimation these seemingly lifeless regions, while practical barriers arise logistical financial limitations conducting studies soils. Although few have quantified surface flux net sink areas, most lack continuous, long-term monitoring soil flux. As result,...
The development of new affordable sensors, and the ability to log high-resolution data for long periods time can potentially revolutionize environmental sciences. Collecting spatiotemporal requires sensor grids that are often costly not necessarily modular enough fit a specific experimental objective. These limiting factors be solved using open-source hardware. In our Open Digital Environmental Lab, we develop integrate complex arrays into research simultaneously measure multiple parameters,...
The Earth's surface forms a dynamic boundary characterized by continuous gas exchanges between the critical zone and overlying atmosphere. As global concern grows over climate change driven increasing levels of greenhouse gases – such as carbon dioxide (CO2) methane (CH4) abandoned oil, gas, even groundwater wells can be significant sources these emissions. Here, we monitor CO2 oxygen (O2) quantify flux in two different recharge one that extends below level (wet well) reaches into...
Soil gas fluxes are an important signal for ecosystems and various soil functions, as soils can be both sources sinks of greenhouse gases (GHG). Because  this critical role, research has focused mainly on GHGs, while other species have received much less attention. O2 concentration is key to many processes, such ammonification, nitrification denitrification, root growth. Studying the relationship between CO2 exchange at soil-atmosphere interface or within profile would better...
Due to increasing flood risks related climate change and urbanization, solutions addressing environmental challenges must be more effectively integrated into urban environments. Green spaces blue-green infrastructure, which combine water, vegetation, recreational areas, can contribute both risk mitigation while the heat island effect, ultimately enhancing quality of life in cities. These facilities also promote biodiversity ecological resilience, supporting stable ecosystems providing green...
Abstract The southern Central Valley of California is one the most productive agricultural regions in world. Yet, decades groundwater use beyond sustainable yield have left rural communities highly vulnerable to shortages and contamination their drinking water supply. As state regulation begins address these issues, a need exists design adaptive appropriate management systems increase resilience communities. Targeted managed aquifer recharge on land (Ag‐MAR) near such strategy that could...
Abstract. The use of wireless sensor networks to measure soil parameters eliminates the need remove sensors for field operations, such as tillage, thus allowing long-term measurements without multiple disturbances structure. Wireless also reduce above-ground cables and risk undesired equipment damage potential data loss. However, implementing in studies usually requires advanced costly engineering knowledge. This study presents a new underground, wireless, open-source, low-cost system...
Advances in gas sensors and open-source hardware are enabling new options for low-cost light-weight sampling devices that also robust easy to use construct. Although the number of studies investigating these has been increasing last few years, they still scarce with respect agricultural applications. Here, we present a complete system high-accuracy measurements temperature, relative humidity, luminosity, CO2 concentrations. The suite is integrated on previously developed HyperRail device...
Wearing masks and face coverings helps reduce transmission of respiratory diseases. Much prior research on mask filtration efficiency has focused fabric type, with less consideration given to design shape. Here, we present evidence that increasing the mouth-mask separation distance engenders an increase in mask-fabric toward expiratory aerosols emitted via vocalization, which attribute a decrease jet velocity expansion breath-mask contact area. We further assess performance new reusable...
Agricultural managed aquifer recharge (Ag-MAR, on-farm recharge), where farmland is flooded with excess surface water to intentionally groundwater, has received increasing attention by policy makers and researchers in recent years. However, there remain concerns about the potential for Ag-MAR exacerbate nitrate (NO
Abstract. Nitrate (NO3-), mainly leaching with soil pore water, is the primary nonpoint source pollutant of groundwater worldwide. Obtaining real-time information on nitrate levels in soils would allow gaining a better understanding sources and transport dynamics through unsaturated zone. However, conventional detection techniques (e.g. sample analysis) necessitate costly, laboratory-grade equipment for analysis, along human resources, resulting laborious time-intensive procedure. These...
Long-term monitoring of Rn-222 and CO2 at a depth several tens meters the Sde-Eliezer site, located within one Dead Sea Fault Zone (DSFZ) segments in northern Israel, has led to discovery clear phenomenon that both gases are affected by underground tectonic activity along DSFZ. It may relate pre-seismic processes associated with accumulation relaxation lithospheric stress strain producing earthquakes. This approach assumes climatic influence on Physico-chemical parameters is limited since...
Agricultural managed aquifer recharge (Ag-MAR) is a promising approach to replenish groundwater resources using flood water and cropland as spreading grounds. However, site selection, particularly the layering of sediment deposits in subsurface, can greatly influence Ag-MAR efficacy it controls flow solute transport vadose zone. In this study, we use HYDRUS-1D software simulate from land surface table three zone profiles (LS, MS, HS) characterized by differing fractions sand (44 %, 47 64 %)....

Abstract Understanding air exchange via boreholes, shafts, and wells is important for Earth environmental sciences because of their potential role increased evaporation greenhouse gas emissions. Here, we investigated the effect atmospheric temperature variability on transport a borehole as function its diameter. Field experiment included five boreholes with diameters ranging from 0.10 to 0.38 m depth 3 an artificial water table at −2.7 m. Temperature was recorded in each 1‐min intervals 1...
Abstract. Understanding air exchange dynamics between underground cavities (e.g., caves, mines, boreholes, etc.) and the atmosphere is significant for exploration of gas transport across Earth–atmosphere interface. Here, we investigated role atmospheric conditions in controlling inside boreholes using situ field measurements. Three geometries were explored: (1) a narrow deep shaft (0.1 m wide 27 deep), ending large cavity; (2) same after pipe was lowered separated from (3) large-diameter...
