💧✨ Topic: groundwater flow ✨💧

okay bestie, welcome to the groundwater flow topic page, the lil corner of the GRASS User's Manual where the water underground gets its whole moment 💅 no cap.

Here's the lineup, two absolute icons of subsurface hydrology:

• r.gwflow — Numerical calculation program for transient, confined and unconfined groundwater flow in two dimensions. 🦋
• r3.gwflow — Numerical calculation program for transient, confined groundwater flow in three dimensions. 🔥

See also the corresponding keyword groundwater flow for additional references. (iykyk, the keyword is where the extra lore lives 🌸)
