Dr. Josué Medellín-Azuara

Associate Professor

Josué Medellín-Azuara is an Associate Professor of Environmental Engineering at the University of California, Merced. He is also an Associate Director of the UC Agricultural Issues Center, and an Adjunct Research Fellow at the Public Policy Institute of California. His areas of expertise include the development of large-scale hydro-economic models for water supply, the economics of agricultural, environmental and urban water uses, adaptation to climate change, integrated water management, and consumptive water use. He has a special interest in the Sacramento-San Joaquin Delta and other areas of California. Josué’s expertise also includes economic impact studies with an emphasis on the agriculture-related sector. He has experience working for industry and as a consultant for government agencies, NGOs, industry, and academia including the Natural Heritage Institute, the Stockholm Environment Institute, The World Bank, the Catholic University of Chile and the University of Rio Grande do Sul. Josué has served as an official for the California Water and Environmental Modeling Forum since 2013. Josué has degrees in engineering, business and economics, and he obtained his Ph.D. from the University of California, Davis with a dissertation on managing water in the Colorado River.



Current Projects

Josué Medellín-Azuara’s research crosses a variety of fields connecting agriculture, water, and the stakeholders involved. While his specialty centers around modeling water use and economics in agriculture he has branched out to connect with stakeholders from all sides.

University of California Merced


Hydrology & Climate (ENVE110)

Basics of the global climate, hydrologic cycle, and critical zone are discussed. Fundamentals of surface-atmosphere water and energy exchange in the form of precipitation, snow, evaporation, and transpiration form the basis for analysis of hydrologic systems. Principles of surface and subsurface flow, statistical and probabilistic methods, unit hydrographs, and flood frequency analysis & flood routing are also covered. Course focus is primarily in scientific concepts, with design considerations forming the basis for a final project.

Engineering Economic Analysis (ENGR155)

Application of economic principles regarding problems in engineering are explored. During the semester, students are introduced to the mathematical and conceptual basis on which project analysis is built. The techniques and tools necessary for making informed financial decisions in the engineering practice are discussed. Topics such as the time value of money, interest, equivalence, cost-benefit analysis, depreciation, taxes, cash flow, and financial risk are covered.

Environmental Systems Seminar (ES291)
ES291 goals

(1) To gain exposure to a range of current science topics in Environmental Systems and Earth System Science from researchers working actively in their field; (2) to have an opportunity to interact with guest speakers, ask questions, and discuss research and career opportunities from experts; and (3) to gain experience critiquing a scientific presentation and writing a concise summary about a presentation in order to improve analytical and communication skills.
