...ensuring reliable predictions by combining outputs from various climate models. It highlights significant declines in discharge and shifts in seasonal hydrological patterns by the end of the century, emphasizing the basin's sensitivity to climate dynamics."

According to the authors: "The study uses four conceptual hydrological models combined with a degree-day snow module to simulate the streamflow. A multimodel ensemble of CMIP6 GCMs was created using Bayesian model averaging, ...

Assistant Professor of Hydrogeology About Western: Western Washington University, with over 15,000 students in seven colleges and the graduate school, is nationally recognized for its educational programs, students and faculty. The campus is located in Bellingham, Washington, a coastal community of 90,000 overlooking Bellingham Bay, the San Juan Islands and the North Cascades Mountain range. The city lies 90 miles north of Seattle and 60 miles south of Vancouver, British Columbia. Western has additional sites in Anacortes, Bremerton, Everett, Port Angeles, and Poulsbo. Western is recognized nationally for its successes, such as being named one of the top public master's-granting institutions in the Pacific Northwest for 25 years in a row by U.S. News & World Report. About the Geology Department: The Geology Department has 17 faculty, offering BA, BS and MS programs in Geology, Geophysics, and Science Education, serving approximately 190 majors. The department has strengths in field and lab-based teaching and research in geomorphology, igneous petrology, geophysics, hydrogeology and envionmental/engineering geology, planetary geology, sedimentology, science education, and structure/tectonics. Additional information about our programs can be found at https://geology.wwu.edu/. The Geology Department strives to further Western's identity as an institution that welcomes and embraces diversity and encourages applications from diverse candidates. About the Position: The ideal candidate will support our department's ability to produce workforce-ready geoscientists. We seek individuals who are enthusiastic about teaching and who will establish a productive research program that involves undergraduate and Master's-level students. Broad areas of research interest may include, but | are not limited to, groundwater-surface water interactions, environmental hydrogeology, and groundwater systems (e.g-geothermal, fault zone, coastal, mountain). Teaching responsibilities will in…
