I was actually thinking of JP's great work when I saw Gemini for model development in the classroom. You can see the HTML code in the browser, yes. I was mainly thinking about overcoming the barrier of coding in exploring model parameters, input - output relationships, & process feedbacks.

As a new prof, I am exploring approachable ways to teach about catchment hydrology modeling. A lack of students'coding skills are limiting the opportunities. Google Gemini with Canvas has the potential to code simulators based on text input. See screen recording of quick example. What do you think?

As I take with students our first water samples for isotope analyses in North Carolinian catchments I think of "a magic dwells in each beginning". It's fun to have a study site nearby and add to ongoing NCSU and USFS research.

Tracers also show that in many landscapes, trees use water from winter precipitation during the summer growing season, highlighting complex storage-and-release dynamics that simple water balance models might miss.

Matthias Sprenger @matthiasprenger.bsky.social · 7d

These models have led to important discoveries, like the "old water paradox"—stormflow is often dominated by older, stored water, not just the recent rainfall! This reveals the relevance of catchment storage.

Water mixing processes in surface waters and groundwaters (gw) are typically studied using tracer-aided mixing approaches. Typical end-members are illustrated in blue. Water compartments that are considered as end-members or mixtures, depending on the study, are shown in blue (end-member) and red (mixtures).

Matthias Sprenger @matthiasprenger.bsky.social · 7d

How do we track water from a raindrop to an aquifer? Tracer-aided mixing models use naturally occurring markers to identify water flow paths and quantify the contributions of different sources (like rain vs. groundwater) to streamflow.

Water exchange and mixing in the atmosphere-vegetation-soil continuum. Blue boxes represent end-members, red boxes represent mixtures, and the blue-red box represents both end-members and mixtures.

What is the Critical Zone (CZ)? 🌍 It's Earth's living skin—a dynamic interface where air, water, soil, plants, and rocks interact. Understanding water's journey through the CZ is vital for safeguarding our water resources and ecosystems.

Conceptual model of the water compartments (boxes) and water fluxes (italic text) within the Critical Zone that are typically studied using tracer-aided mixing models. Light blue boxes indicate compartments that are considered to be end-members. Red boxes indicate compartments that are considered as mixtures. Boxes with both colors represent compartments that are either end-members or mixtures. “Gw” stands for groundwater.
