Submarine Groundwater Discharge Estimation

Xuan Yu, University of Delaware
Author Profile


The objective of this exercise is to introduce students to the concept of submarine groundwater discharge (SGD). This exercise contains steps that allows the students walk through the entire process of obtaining the necessary data, processing the data, and using the data for SGD estimation.

Intended Audience

This unit is intended for upper level undergraduate or lower level graduate students in hydrology, hydrogeology, and geology/earth sciences.

Conceptual Learning Outcomes

Students demonstrate the understanding of submarine groundwater discharge (SGD) and surface runoff.
Students demonstrate the understanding of temporal variations of SGD and surface runoff.

Practical Learning Outcomes

Students will be able to use R to process and visualize data.
Students will be able to use WaterML to download hydrologic data from CUAHSI.

Student Time Required

3-4 hours
