research overview

  • Dr. Overeem's research involves the development of predictive surface process models, which form a tool to quantify responses of sedimentary systems to changing environmental conditions. She uses field studies to critically assess model performance. Current field studies are in regions of rapid change; the importance of working in these regions for a global understanding of the changing environment. Current research projects involve Arctic Rivers in Greenland and Alaska, but also large Asian Deltas, and the Rio Grande River system in the US. Overeem uses her modeling expertise to support the Community Surface Dynamics Modeling System (CSDMS) Facility team at the University of Colorado. CSDMS promotes the modeling of earth surface processes by developing, supporting, and disseminating integrated software modules that predict fluxes of sediments and nutrients in landscapes and their sedimentary basins.

courses taught

  • GEOL 1010 - Exploring Earth
    Primary Instructor - Fall 2018 / Spring 2020 / Spring 2022
    Introductory geology for majors and non-majors. Studies Earth, its materials, its characteristics, its dynamic processes, and how it relates to people. Separate lab (GEOL 1030) is recommended. Degree credit not granted for both GEOL 1010 and GEOL 1012.
  • GEOL 3340 - The Cryosphere: Earth's Icy Environments
    Primary Instructor - Spring 2024
    Serves as an advanced introductory course in to the cryosphere for science majors. The course covers the nature of ice and the icy component of the Earth System, and how changing ice affects society. The course will not cover sea ice. Formerly offered as a special topics course. Same as GEOL 5341.
  • GEOL 3600 - Introduction to Python Programming for Earth Scientists
    Primary Instructor - Fall 2023
    Introduces students to scientific computing and computer programming using the Python language. Emphasis is on scientific applications such as data input and analysis, plotting, and simulation. Examples are drawn from earth and environmental sciences. Course covers variables, operations, data types, conditionals, loops, data structures, array calculations, and libraries for data analysis and plotting. Coursework is primarily based on weekly programming assignments. Recommended prerequisite: Introductory course in GEOL, ENVS, GEOG, ATOC, or EVEN.
  • GEOL 4700 - Special Geological Topics
    Primary Instructor - Fall 2019 / Fall 2020 / Fall 2021
    Studies in selected geological subjects of special current interest (for undergraduates). May be repeated up to 9 total credit hours within a term.
  • GEOL 4723 - Field Studies in Sedimentology
    Primary Instructor - Summer 2021
    Provides students experience in observing and interpreting sedimentary rocks in the field. We will visit outcrops in CO and UT spanning a range of depositional environments, including eolian, lacustrine, fluvial, and marine. Developing observational and notetaking skills will be emphasized; students will be responsible for contributing to a group field guide based on their guided field observations at each site.
  • GEOL 4725 - Field Based Special Topics in Geoscience
    Primary Instructor - Spring 2021 / Spring 2022 / Spring 2024
    Explores selected geological subjects of special interest in a field setting. May be repeated up to 8 total credit hours. Same as GEOL 5725.
  • GEOL 5700 - Geological Topics Seminar
    Primary Instructor - Fall 2019 / Fall 2020 / Fall 2021 / Fall 2023
    Offers seminar studies in geological subjects of special current interest. Primarily for graduate students, as departmental staff and facilities permit. May be repeated up to 15 total credit hours provided that topics vary.
  • GEOL 5702 - Geomorphology Seminar
    Primary Instructor - Spring 2020 / Spring 2021
    Explores the dynamics and forms of the earth's surface through critical reading and discussion of both classical and modern literature. May be repeated up to 10 total credit hours.
