Dr. Mazdak Arabi is the director and founder of the One Water Solutions Institute at Colorado State University. His research is primarily focused on development of decision support systems for management of water resources at the watershed scale. To make informed decisions, policy makers should have the tools necessary to identify areas that are most vulnerable to erosion and contaminant transport, and subsequently assess tradeoffs between environmental and economic impacts of management actions. Dr. Arabi has developed and demonstrated optimization-based approaches to facilitate development of watershed management plans that achieve water quality goals at significantly lower costs. He has published analytical and computational methods to support both deterministic and probabilistic evaluation of watershed-scale benefits of best management practices.
