JAN FRANKLIN ADAMOWSKI M.B.A., Ph.D., P.Eng JAN FRANKLIN ADAMOWSKI M.B.A., Ph.D., P.Eng. Associate Professor Department of Bioresource Engineering, Faculty of Agricultural and Environmental Sciences, McGill University RESEARCH INTERESTS My research explores engineering, as well as socio-economic and management problems, in the field of water resources with the aim of developing innovative and useful approaches to help reduce the vulnerability, as well as enhance the resilience, adaptive capacity, and sustainability of water resources systems around the world in the face of increasing challenges, uncertainty, and climate change variability. In the field of engineering hydrology, I have conducted extensive research on developing new methods for, among other things: hydrological time series data improvement (i.e., filling gaps, extending short records, etc.); input variable selection for hydrological models; hydro-meteorological trend estimation; and hydrological forecasting. For example, I have made significant contributions to try and address the issues of non-linearity, non-stationarity, and uncertainty assessment in artificial intelligence based hydrological forecasting. In the field of water resources management, I have conducted research in a number of areas, including: i) developing a new Participatory Model Building Framework (PMBF); ii) developing a new approach (that is part of the PMBF) in socio-hydrological modeling to dynamically link stakeholder-built system dynamics models with physical/process based models; iii) a critical examination of the concept of payments for ecosystem services, as well as exploring the use of ‘frame theory’ in the context of ecosystem services to facilitate conflict resolution related to contentious water strategies and policies; iv) and exploring the use of ‘virtual learning platforms’ to facilitate multi-loop social learning in water resources management. As an example of my research in water resources management, I developed a new and unique participatory model building approach, called the Participatory Model Building Framework (PMBF), which facilitates the representation and dynamic modeling of the interactions and feedbacks between physical (e.g., hydrological and related environmental processes) and socio- economic processes in water systems, and also includes key stakeholders in the development and use of the model. Research output: I have 216 refereed journal papers published, 8 additional referred journal papers in press, 25 additional refereed journal papers accepted (in the last year), 3 monographs published, and 3 books published. I have been the recipient of 8 major awards, and I have given 7 keynote talks at conferences. My Hirsch Index (Scopus = 31 and Google Scholar = 34), i10 Index of 95 and total citations (Scopus = 3348 and Google Scholar = 4763) are excellent for my fields of research.

    397 SOIL SALINITY CONTROL UNDER BARLEY CULTIVATION USING A LABORATORY DRY DRAINAGE MODEL Shahab Ansari 1,*, Behrouz Mostafazadeh-Fard 2, Jahangir Abedi Koupai3 Abstract The drainage of agricultural fields is carried out in order to control soil salinity and the water table. Conventional drainage methods such as lateral drainage and interceptor drains have been used for many years. These methods increase agriculture production; but they are expensive and often cause environmental contaminations. One of the inexpensive and more environmental friendly methods that can be used in arid and semi-arid regions to remove excess salts from irrigated lands to non- irrigated or fallow lands is dry drainage. In the dry drainage method, natural soil system and the evaporation of fallow land is used to control soil salinity and the water table of irrigated land. There are few studies about dry drainage concepts. it is also important to study soil salt changes over time because of salt movements from irrigated areas to non-irrigated areas especially under plant cultivation. In this study a laboratory model which is able to simulate dry drainage was used to investigate soil salts transport under barley cultivation. The model was studied during the barley growing season and for a constant water table. During the growing season soil salinities of irrigated and non-irrigated areas were measured at different time. The Results showed that dry drainage can control the soil salinity of an irrigated area. The excess salts leached from an irrigated area and accumulated in the non-irrigated area and the leaching rate changed over time.

  • Concentrated Alkaline Recharge Pools for Acid Seep Abatement: Principles, Design,Construction and Performance1
    CONCENTRATED ALKALINE RECHARGE POOLS FOR ACID SEEP ABATEMENT: PRINCIPLES, DESIGN,CONSTRUCTION AND PERFORMANCE1 Jack R. Nawrot', Pat S. Conley2, and James E. Sandusky' Abstract: Concentrated alkaline recharge pools have been constructed above previously soil covered acid gob at the Peabody Will Scarlet Mine to abate acid seeps. Preliminary monitoring results (1989-1994) from a concentrated alkaline recharge pool demonstration project in the Pit 4 area have documented a 45 to 90 % reduction in acidity in the principal recharge pool groundwater zone. A 23 % reduction in acidity has occurred in the primary seep located downslope from the alkaline recharge pools. The initial improvements in water quality are seen as a positive indication that groundwater acidity will decrease further and amelioration of the acid seep will continue. Additional Key Words: acid seeps, mine refuse, acid mine drainage, alkaline recharge. Introduction Covering acid producing coal refuse with 4-ft of soil cover does not preclude pyrite oxidation under the soil cover. When pyrite oxidation does occur overlying soil covers may become acidified and acid seeps may be generated following several seasons of rainfall infiltration and flushing cycles. Burial of potentially acid producing coal waste in a zone of fluctuating groundwater elevations is conducive to chronic acid seep generation when. the upslope groundwater chemistry has insufficient alkalinity to neutralize downslope acid groundwater pools generated by the buried refuse. Soil covering after limestone is applied in sufficient quantities to overcome the potential acidity · of refuse, or limestone amendment and direct seeding are effective reclamation techniques that enhance long-term vegetation success and establish a favorable acid-base balance (Warburton et al.

  • Assessing US Farm Drainage
    Assessing U.S. Farm Drainage: WORLD Can GIS Lead to Better Estimates of Subsurface RESOURCES Drainage Extent? INSTITUTE ZACHARY SUGG SUMMary Extensive agricultural subsurface tile drainage in the Midwestern U.S. has important implications for nutrient pollution in surface water, notably the “dead zone” in the Gulf of Mexico. However, drainage data limitations have constrained efforts to effectively factor tile drainage into regional economic and environmental impact studies. Improved drainage data would be a valuable addition to future modeling applications. In light of this need, a methodology incorporating a geographic information system (GIS) analysis based on soil and land cover maps was implemented to create a set of county-level tile drainage extent estimates. • For several leading agricultural drainage states, maps of soil drainage characteristics were created and overlaid with row crops. Areas with row crops and poorly drained soils were calculated, disaggregated to the county level, and reduced by a percentage based on published estimates to approximate subsurface drainage. Results for eight highly-drained Midwest states were compared to previous estimates. A range of tile drainage estimates were compiled, along with a final best-guess county- level database of tile drained area. • This represents just one set of methods, and without sufficient data for verification it may be difficult to judge its effectiveness compared to others. By demonstrating one method, we hope to encourage further exploration of the use of GIS for predicting and assessing farm drainage. More importantly, we aim to further the dialogue regarding the relationship between drainage and water quality in the U.S. and highlight the need for improved measurement of this key agricultural practice.

  • Estimation of Root-Zone Salinity Using Saltmod in the Irrigated Area of Kalaât El Andalous (Tunisia)
    J. Agr. Sci. Tech. (2013) Vol. 15: 1461-1477 Estimation of Root-zone Salinity Using SaltMod in the Irrigated Area of Kalaât El Andalous (Tunisia) ∗ N. Ferjani 1 , M. Morri 2, and I. Daghari 2 ABSTRACT In Tunisia, Kalâat El Andalous irrigated district is one of the most affected areas by salinization. The objective of this study was to predict the root zone salinity (over 10 years) in this area using the SaltMod simulation model for subsurface drainage system. SaltMod is based on water balance, salt balance model, and seasonal agronomic aspects. In the pilot area, irrigated vegetables crops such as tomato ( Lycopersicum esculentum ), melon ( Cucumis mela ) and squash ( Cucurbuta maxima ) occupy the field during summer and rainfed wheat during winter. The model predicted more or less similar values of electrical conductivity in the root zone. Highest value of electrical conductivity reached during the irrigation season was 7.7 dS m -1. Following the fall rains, there was a decrease of the soil salinity when the average minimum value of electrical conductivity was 3.1 dS m-1. The simulation also showed that decreasing the depth of the drain did not change significantly the root zone salinity. The depth of the drain could be reduced to 1.6 m without any damage to crops. There was a slight reduction in drainage flow when the depth of the drain changed from 1.8 m to 1.2 m. Decrease of the drain depth decreased water table level. There was no variation in root zone salinities due to change in drain spacing.

However, 20-30 million ha of irrigated land are now seriously affected by problems of waterlogging and salinisation caused by poor water management and inadequate drainage. Smedema and Ochs (1997) estimate that the affected area is growing by about 5% each year. The World Bank (WB, 1993b) identified inadequate or inappropriate drainage as the most severe long-term problem facing agricultural production. Without effective drainage, the benefits of irrigation are forfeit. Affected lands are characterised by one or more of the following constraints: reduced cultivated area, reduced yield, curtailed cropping seasons, limited choice of crops. Many of the problems constraining drainage are social, economic or institutional in nature. Nonetheless, there are substantial technical issues directly affecting irrigation scheme performance and output, for which practical solutions remain to be developed. Some technologies have been successfully transferred from the developed to the developing world, but there is an urgent need to produce appropriate solutions, particularly for humid areas.
