I wrote about it here.

A post from Dr. Chris Skinner led me to a modern take on this theme.
A group of people led by Dai Yamazaki have been coding a model for the movement of water down and through a hillslope using Scratch and have made the code available.

New paper is out. We develop a rainfall-runoff model using educational programming language Scratch, and make it playable as a game. We found through a workshop that learning through game helps to more deeply understand flood mechanism. pic.twitter.com/wb1mzZz91x— Dai YAMAZAKI / 山崎 大 (@BigAsMountain) January 19, 2024
