Hillslope hydrology of the MacDonald-Dunn Forest

Department Affiliation:
Forest Engineering Resources & Management
Project Location:
Peavy Forest Science Center & OSU Research Forests (MacDonald-Dunn Forests)
Project Description:
The project will investigate how water moves through steep forested hillslopes, from rain to hillslope soils to streams and rivers. This is important because watershed-scale processes, like susceptibility to landslides and water supply, are controlled by landscape characteristics like slope angle, soil depth, and elevation. To better understand these controls, this proposal would support one or two students to help install two monitoring stations in the MacDonald Dunn Forest that measure rainfall, soil water content, and soil water pressure. One station will be placed at higher elevation below a ridgeline, the other will be placed at a lower elevation near the bottom of a gully.
Over the course of the project, the student (or students) will assist in the installation of monitoring equipment, station maintenance, and preliminary analysis to compare the two sites. The field installation includes assisting the faculty mentor in digging a soil pit and characterizing soils; station assembly; and site characterization and documentation. Maintenance includes approximately monthly visits to clean rain gauges and check instruments. Preliminary data analysis will include data organization and basic comparison of time-series data at each station. Potential questions for analysis include: how well do the two sites correlate? Which site is wetter overall? Which site responds more quickly to rainfall?
In addition to improving understanding of hillslope hydrology in our local watersheds, this project will also support ongoing and anticipated Extension activities, such as site tours to land and watershed managers in the region. The long-term goal of the project is to serve data to the public for awareness of real-time conditions in their local watershed, and to use hydrologic data in trainings and OSU Extension publications for land managers.
Describe the type of work and tasks you anticipate the student will perform:
The student will assist in the installation of hillslope hydrologic monitoring equipment at two locations, perform monthly station maintenance, and begin preliminary data analysis, including data management of time series data, site correlation, and site comparison. The student may also have opportunities to support extension and outreach activities like site tours. As a secondary task, the student may assist with debris flow mapping and using lidar and satellite imagery.

Hourly rate of pay:
$15/hr
What is the expected timeline of this project?:
The anticipated start date is in early-mid November for installation, ongoing maintenance, and data management. This will include two longer field days (4-8 hours) scheduled with the student and then a flexible weekly schedule for monthly site maintenance and data management training. Preliminary data analysis will begin in winter term (January or February) and continue through spring term, with 3-5 hours of analysis per week plus a monthly site visit (3-5 hours) for maintenance.
Are special skills or knowledge required to work on this project?:
Yes
Will training be provided?:
Yes
How many hours per week do you anticipate a student to work?:
Three to five hours per week on average. There will be one or two longer field days for equipment installation at the beginning of the project (two 4-8 hour days). After installation, ongoing maintenance will include monthly site visits (2-5 hours once per month) and weekly data management and analysis tasks (3-5 hours per week).
How many hours per week do you anticipate engaging in direct mentorship?:
0.5-1 hrs/week, with additional direct mentorship at the beginning of the project.
Detail your mentorship plan:
Before installation, I will meet with the student(s) (~2 hours total) to provide training on equipment, site selection, and fieldwork expectations. I will accompany the student(s) in the field for the first 2 or more site visits (4-8 hours each) to guide equipment installation and train the student in station assembly and installation. Thereafter, I will meet with the student(s) approximately once per week or every other week to determine upcoming tasks, provide project guidance, and ongoing training in hydrologic monitoring and data analysis.
