Noam Weisbrod is a Professor of Hydrology in the Department of Environmental Hydrology and Microbiology at the Zuckerberg Institute for Water Research (ZIWR), which is part of the Blaustein Institutes for Desert Research at Ben Gurion University of the Negev (BGU). He also serves as the director of the ZIWR.

Career

Weisbrod has been involved in various international missions and evaluation panels to assess local water realities, in places like Chile, Inner Mongolia, Namibia[1] and the Galapagos Islands. He is a member of the steering committee for BGU – University of Chicago cooperation in Water Sciences,[2] and the steering committee for “BusinessH2O – Water management best practices from USA and Israel”.[3][4]

Research

Weisbrod has co-authored more than twenty papers in the subject of Earth sciences. These include research in the following areas and subjects.

Subsurface flow and transport

Research involving the exploration of processes and mechanisms related to flow and transport phenomena in the subsurface and at the Earth-atmosphere interface:

  • New method for sampling groundwater colloids under natural gradient flow conditions.[5]
  • Light transmission technique for the evaluation of colloidal transport and dynamics in porous media.[6]
  • Impact of particle size on colloid transport in discrete fracture.[7]
  • Colloid transport through saturated sand columns and the influence of physical and chemical surface properties on deposition.[8]
  • Colloid-facilitated transport of lead in natural discrete fractures.[9]

Fractures and discontinuities

The role of surface-exposed fractures in groundwater salinization and earth-atmosphere gas exchanges and the role of fractures and other discontinuities within the Earth's surface, items which fundamentally impact the Earth-atmosphere interaction:

  • The role of fractures in Earth-atmosphere gas exchange.[10]
  • The cause and effect pathways of atmospheric winds and fracture ventilation.[11]

Soil evaporation

Soil evaporation and the impact of various soil and atmospheric conditions on this process, including the links between soil evaporation and salinization:

  • The use of fluorescent dyes as tracers in highly saline groundwater.[12]
  • Combined evaporation and salt precipitation in homogeneous and heterogeneous porous media.[13]

Contaminants

The transport of contaminants (salts, VOC's, perchlorate, Cr, explosives, pesticides and pharmaceutical waste) below industrial zones and non-point source pollution (mainly agriculture). These include the issues surrounding in situ bioremediation and the transport mechanisms of various contaminants — chief among them oil-emulsions and surfactants in soils:

  • Impact of intermittent rainwater and wastewater flow on coated and uncoated fractures in chalk.[14]
  • Accumulation of oil and grease in soils irrigated with greywater and their potential role in soil water repellency.[15]
  • Steady-state homogeneous approximations of vertical velocity from EC profiles.[16]
  • Isotopic evidence and quantification assessment of in situ RDX biodegradation in the deep unsaturated zone.[17]
  • Observations on vertical variability in groundwater quality and the implications for aquifer management.[18]
  • Decentralized wetland-based treatment of oil-rich farm wastewater for reuse in an arid environment.[19]
  • Modeling the impact of solute recycling on groundwater salinization under irrigated lands, involving a study of the Alto Piura aquifer in Peru.[20]

Salt and fresh water

Subsurface processes along the Dead-Sea shore, including the influences of salt and fresh-water:

  • Line-source multi-tracer test for assessing high groundwater velocity.[21]
  • Colloid transport in porous media and the impact of hyper-saline solutions.[22]
  • Dynamic dissolution of halite rock during flow of diluted saline solutions.[23]

Rural water access

Problems involving rural water access and development:

  • Adapting enzyme-based microbial water quality analysis to remote areas in low-income countries.[24]
