Join Roseann online for the Desert Laboratory on Tumamoc Hill's spring workshop series: SEEING MATH IN NATURE!

Picture a classic aerial view of a river, and you will see in your mind a series of loops and bends . . . these are called meanders. As water flows and curves, material such as sand and gravel build on the inside of the bend. The outside of the loop is left clean and unprotected, where erosion accelerates, further increasing the meandering in a powerful positive feedback loop. The result is a beautiful natural pattern that can be predicted mathematically in many forms: rivers, snake locomotion, the growth of brain coral. Hydrologist and wetland restoration specialist Anthony Luketich of the Watershed Management Group will talk about these processes, and then artist Roseann Hanson will lead a session on field sketching the Tucson stretch of the Santa Cruz River, which is in the process of being reborn after a century of stasis.
