The Environmental Flow & Transport Lab at New Mexico Tech is seeking applications for two PhD student (or exceptional MS student) in Hydroinformatics with an emphasis on merging hydrologic transport processes, fluvial geomorphology, and nutrient and contaminant dynamics in river systems. The appointment will support a large-scale field and modeling project aimed at improving the characterization of river hydrogeomorpohology and its cumulative influence on water quality (Figure 1). The project integrates data mining and synthesis of large physical and biogeochemical datasets with new physics-based models for transport in large river networks (Figure 2).

Research goals include the conceptualization and analysis of detailed bedform-scale flow and transport models and assembling and assimilating hydrogeomorphic data into a new river corridor transport model to assess cumulative effects, and forecast outcomes for changing water quality at the scale of the nation.

Applicants are expected to work collaboratively with colleagues at the Pacific Northwest National Laboratory (PNNL) and the USGS River Corridor Powell Center. Applicants with a quantitative background and experience in programming and GIS will be given preference. The successful candidate will join the Hydrology Program at New Mexico Tech’s Dept. of Earth & Environmental Science. Computing facilities and travel are supported. Interested applicants should email a CV, transcripts, and a one-page statement of past and present research goals to Dr. Jesus D. Gomez-Velez (jesus.gomezvelez@nmt.edu). Review of applications begins September 1, 2017, and the position will remain open until filled.
