LIST OF MAJOR ACHIEVEMENTS

1. General Contribution to Agricultural Sciences

My long-term research interests cover theoretical and practical aspects in the areas of (i) water flow and chemical transport in porous formations; (ii) Estimation of soil hydraulic properties; (iii) Characterization of the spatial heterogeneity of soil properties relevant to flow and transport; (iv) Modeling of flow and transport at the field scale; (v) Contamination of soils and groundwater; and (vi) Modeling of flow, transport and crop production and its application to management of saline and sodic soils. My recent research efforts focus on modeling of preferential flow of tracers and organic contaminants in the vadose zone (BARD project IS-2859-97 with W. A. Jury), on the development of predictive tools for the transport of contaminants through the spatially-heterogeneous combined vadose zone-groundwater flow system (BSF project 96-00357 with Y. Rubin; BARD project IS-4090-08 with D. M. Tartakovsky and S. P. Neuman), on the upscaling of hydraulic conductivity and macrodispersion tensors in spatially-heterogeneous soils (BARD project US-3287-01R, with R. Zhang), and on subsurface flow and transport in a steep, spatially-heterogeneous, hillslope under rainfall (NATO-CLG project with A. Fiori).

During the late 1970's my work on the effect of the irrigation waters' solutes concentration and composition on the hydraulic properties of saturated-unsaturated soil systems (papers 4 & 5 with E. Bresler) and, consequently, my work during the 1980's on the transport of interacting mixed Na/Ca solutes in partially saturated soils (papers 31 & 32), were one of the first few attempts to investigate this complicated system under transient, unsaturated flow conditions. I was awarded (in 1979) the Israel Society of Soil Science Mokady's Award for my M.Sc. thesis.

During the early 1980's, my work on the development of fast field methods to characterize the hydraulic properties of field soils (papers 6 & 7 with E. Bresler), was one of the first attempts to develop methods suitable for the estimation of joint probability density functions of soil hydraulic properties at the field scale. The procedure was successfully applied in research projects which were conducted in Bet Dagan (papers 9 & 12 with E. Bresler) as well as in the Arava Valley (papers 14, 16, 17 & 20) and was further developed during the early 1990's (BSF project #87-00017 with J. C. Parker and colleagues) using inverse problem methodology (paper 42).

My work during the early 1980's on the analyses of the spatial variability of soil hydraulic properties (papers 8, 9 & 12 with E. Bresler), was one of the first attempts in soil physics to apply stochastic and geostatistical approaches to analyze the spatial variability of soil hydraulic properties. Latter on, I extended these approaches to design measurement networks to characterize soil hydraulic properties in spatially-heterogeneous fields (paper 18); to evaluate the effect of spatial variability in soil hydraulic properties on water flow and solute transport (papers 10 & 13) as well as on crop yields (papers 19, 22 & 23) in spatially heterogeneous fields; and to design irrigation systems and leaching schemes in spatially variable saline soils (papers 17, 18 & 20). Additional efforts (BARD projects IS-1464-89R with J.C. Parker and US-2294-93 with W. A. Jury) to characterize the spatial variability of the soil hydraulic properties were conducted during the 1990's (papers 43, 44, 57 & 61).

My work during the mid 1980's on the marginal soils of the Arava Valley in Israel (BARD projects US 330-80 and US 844-84 with S. Miyamoto) was one of the few attempts to study the chemical and the physical properties of desert soils (papers 14 & 21) and their spatial variability (paper 17, 18 & 20); the simultaneous transport of water and solutes in the profile of these layered stony soils (paper 24); and the relationships between irrigation management and the soil moisture and salinity regime in these marginal soils and their effect on crop yields (papers 15, 19, 21 & 25).

During the 1990's I collaborate with J. Zaidel on the analysis of transport of organic compounds in the unsaturated zone in relation to groundwater contamination by volatile petroleum products (Water Commission project #55004-90). The results of this collaboration yielded analytical models for the diffusive transport of organic vapors in the unsaturated zone with kinetically-controlled volatilization and dissolution (papers 48, 51 & 55).

The major part of my research work during the 1990's, however, has been focused on the problem of field-scale transport in variably saturated, heterogeneous soils (BARD projects US-1484-88 and US-2294-93 with W.A. Jury and IS-1929-91 with J. C. Parker).

My research work during the early 2000 on the transport of contaminants through the spatially-heterogeneous combined vadose zone-groundwater flow system (BSF project 96-00357 with Y. Rubin) is summarized in paper 70. My recent research work on the upscaling of hydraulic conductivity and macrodispersion tensors in spatially-heterogeneous soils (BARD project US-3287-01R, with R. Zhang) is summarized in papers 75, 76 & 77.

Generally, my research effort during the last fifteen years is directed along two main lines. The research effort along the first line focused on the development of a theoretical framework for modeling solute transport in partially saturated, heterogeneous porous formations, based on a general Lagrangian formulation and a stochastic continuum theory. My earlier work along this line (papers 46 & 47) may be considered as one of the first few attempts to apply this theoretical framework to unsaturated flow systems. The initial theoretical efforts were developed further in subsequent studies, considering statistically anisotropic formations, bimodal formations, reactive solutes and nonergodic transport (papers 52, 53, 54, 56, 60, 62, 64, 74, 79, 81, 88, 89 and 92); furthermore, upscaling procedures were developed for the hydraulic conductivity and the macrodispersion tensors for variably saturated, spatially-heterogeneous formations (papers 43, 75, 76 & 77).

The research effort along the second line (papers 40, 49, 50, 63, 65, 70, 71, 72, 78, 80, 82, 85, 91, 93, 95, 96, 98, 99, 101, 104 and 105) focused on numerical simulations of flow and transport in partially saturated, heterogeneous porous formations. The numerical approach adopted in these studies combines a statistical generation method to produce realizations of the heterogeneous formation properties in sufficient resolution, with an efficient numerical method to solve the partial differential equations governing flow and transport in heterogeneous, variably saturated formations.

These simulations or "numerical experiments" provided detailed information on the consequences of the spatial heterogeneity of the soil properties for the transport of solutes under quite realistic conditions. At the price of reduced generality, they circumvented most of the stringent assumptions of theoretical studies and, facilitated analysis of simplified, yet realistic situations at a fraction of the cost of physical experiments. Furthermore, results of the numerical experiments were used to test the applicability of current stochastic transport models to more realistic field situations. Paper 78 which addressed the problem of field-scale flow and transport for the case in which the flow is coupled to the transport through the dependence of the soil hydraulic properties on solute concentrations, was selected for inclusion in the Science in Action Technology Transfer Program from ASA-CSSA-SSSA.

My numerical study in the early 1990's on the problem of field-scale transport in variably saturated, heterogeneous soils under transient water flow (paper 40) was one the first attempts to analyze this complicated problem in two-dimensional flow systems. The results of this study demonstrated the considerable variability in the solute concentration in space and time due to the complex heterogeneity of the soil hydraulic properties in both the vertical and the horizontal directions in agreement with field observations. The results of this study showed conclusively that existing one-dimensional stochastic vadose-zone transport models may fail to predict the actual spread of a solute plume when the transport takes place to relatively large depths, mainly because of the neglect of the significant vertical heterogeneity in the soil hydraulic properties. The initial effort was developed further in subsequent studies with my colleagues, J. Zaidel (papers 49, 50, 65, 70, 71, 72, 78, 80 and 82), and A. Fiori (papers 82, 83, 84, 86, 87, 90, 92, 94, 99 and 100), considering two- and three-dimensional, highly heterogeneous flow systems, water uptake by plant roots, reactive solutes, combined vadose zone-groundwater flow systems, preferential flows, and spatially-heterogeneous, steep hillslopes and multi-sources.

Paper 82 addresses the important issue of the sampling design problem for monitoring field-scale solute transport and its proper interpretation; the latter are essential for a reliable assessment of the groundwater contamination hazard. The findings of this paper suggest that a pair of sampling points located in the horizontal plane of the field may be sufficient in order to provide relatively accurate estimates of characteristics of the transport (i.e., displacement and spread of the solute plume in the direction of the mean flow, and mean solute BTC) for the entire spatially heterogeneous domain. These findings have important implications with respect to the monitoring of field-scale solute transport, which traditionally requires an extensive soil sampling, which, in turn, might be very expensive.

My research work which focuses on water flow and chemical transport in a realistic, spatially-heterogeneous, variably-saturated flow system, provides a fundamental advance in the fields of stochastic and numerical modeling of field-scale flow and transport in the subsurface. The results of my work extend one's ability to predict water flow and chemical transport in a real-world, complex subsurface, which, in turn, is essential for the assessment of both soil and groundwater contamination hazard.

My scientific work is summarized in more than one hundred research papers published in most of the highly regarded refereed scientific journals, and five reviewed articles in proceedings of symposia. In addition, I was invited to present four general review articles in two books on water flow and solute transport in the unsaturated zone and in the Encyclopedia of Soils in the Environment, to be a Co-editor (with G. Dagan) of a book on flow and transport in soils, and to present more than sixteen invited papers in major international meetings, conferences and workshops. Furthermore, I was acknowledged by the Institute for Scientific Information as a Highly Cited Researcher in the Ecology/ Environment Category.

2. Achievements in applied research specifying major contribution to agriculture in Israel and abroad

As a soil physicist my main interest focuses on the vadose (unsaturated) zone of the soil. This zone plays a critical role in the life-support functions of this planet. Despite its importance, many of the properties of the vadose zone that are most relevant to water and chemical management are poorly understood. In particular, researchers have had great difficulty developing a transport model that can accurately describe the movement and reactions of chemicals following their introduction into the soil. The principal reason for this failing is spatial variability: the soil properties vary so much from point to point that it is not possible to measure them in sufficient detail to use in a conventional model. My research effort in the last twenty five years focused on a different approach to develop a transport model, by expressing it as a stochastic process, so that we need only take sporadic property measurements. I also have developed ways of measuring soil properties that directly yield the statistical properties that we need for the models. My research effort shows great promise as a practical tool for developing a model that can be used to assist in agricultural management, groundwater pollution prevention and cleanup, or waste management.

Over my career as a Principal Investigator, I have been awarded about one million dollars in outside research contract and grant support from Bi-National and State funding sources. I have been awarded eight times major funding from the US-Israel Bi-National Agricultural Research and Development Fund (BARD) and two times from the US-Israel Bi-National Science Foundation (BSF).

Here are some of the practical problems which I addressed during my career:

Quantifying Flow and Transport in Saline/Sodic Soils: A conceptual model was developed to quantify the effect of irrigation waters' concentration and composition on the soil hydraulic properties, and consequently, on the transport of mixed Na/Ca solutes in partially-saturated, saline/sodic soils, under field-scale, transient flow conditions. The model may be used to improve reclamation schemes of saline/sodic soils.

Characterization of the Hydraulic Properties of Field Soils: Fast field method to characterize the hydraulic properties of field soils was developed which enables the estimation of the joint probability density functions of soil hydraulic properties at the field scale. The procedure is successfully applied in other research projects and was further developed using inverse problem methodology.

Development of Leaching Schemes in Spatially Variable Saline Soils: An approach which couples stochastic and geostatistical approaches with conceptual models of flow and transport was developed in order to design leaching schemes for spatially variable saline soils. The procedure improves traditional leaching schemes and may led to the saving of 20% in the required amount of water for leaching.

Development of Irrigation Schemes in Spatially Variable Saline Soils: An approach which couples stochastic and geostatistical approaches with conceptual models of flow and transport was developed in order to design irrigation schemes for spatially-variable soils. The procedure improves traditional irrigation schemes and may led to the saving of 7%-34% in the required amount of water for irrigation, depending on the quality of the irrigation water.

Assessment of Groundwater Contamination: A framework for the modeling of solute flux in partially saturated, heterogeneous porous formations was developed by combining a general Lagrangian formulation with a stochastic continuum theory for unsaturated flow. The approach may be applied for assessment of groundwater contamination hazard by chemicals moving through the unsaturated zone of heterogeneous porous formations, by determining the probability distribution function of the accumulated mass crossing a given horizontal control plane at a given vertical distance from the injection zone, as a function of time.
