Dr. Nesa Ilich is a professional water resources engineer with over twenty years of consulting practice. His practical experience includes integrated multi-purpose river basin management, hydraulics, hydrology, stochastic hydrology, and design of drainage systems.  He has expertise in applications of operations research techniques in design and operation of water resources infrastructure, and he has developed sophisticated simulation and optimization models that were applied in various studies. His previous projects include the World Bank and ADB funded river basin and irrigation planning studies in South East Asia, where he was involved as a senior consultant. Other  engagements in similar capacity include projects with Transalta Utilities Corporation (a large electrical utility corporation in the Province of Alberta, Canada), Brantas River Basin Management Authority (PJT) in Indonesia, Canadian International Development Agency, and Alberta Environment, a Provincial water management agency in Canada. Dr. Ilich has significantly improved Alberta Environment’s Water Resource Management Model (WRMM) through a series of contracts awarded to him since 1987 and exported its use overseas.  This model has been used in numerous multi-disciplinary studies as a tool to aid assessments of water management and basin development issues among a number of stakeholders, including hydro power producers, irrigators, municipalities and various industrial consumers.   Dr. Ilich has recently developed a unique method for generating stochastic hydrologic time series at multiple sites.  He has also authored numerous reports and technical papers published in conference proceedings and peer reviewed journals, and he has received several academic scholarships as well as a professional award of excellence by the Consulting Engineers of Alberta for his work on the Yellow River Basin modeling done in cooperation with Golder Associates Ltd.  Dr. Ilich is Adjunct Professor in Civil Engineering at the University of Calgary where is currently involved in several research initiatives (http://www.schulich.ucalgary.ca/resrch_civil/Civil_Ilich.htm).  He has numerous publications related to hydrology, water resources management and operational research:

Mr. Jorge Dreher graduated in civil engineering in 1978 and obtained M.Sc. in hydraulics and hydrology from the Technical University of Vienna, Austria.  He has 27 years of professional experience as a project manager, planner, consultant, as well as an integrated river basin management expert. Jorge has worked in hydrology, hydrogeology, groundwater flow and modelling, and hydro-informatics.  In recent years he participated in a number of projects that included design and implementation of hydrometeorologic real-time monitoring networks, hydrological modelling, flood forecasting, flood protection and development of hydrological software.  Jorge has extensive knowledge of the EIA process and experience in institutional strengthening and policy implementation within the framework of integrated river basin management. Jorge is fluent in five languages.  He has participated as author or co-author of more than 50 publications, some of which include:
