pool, eddy
淀 centers on still or slowly moving water that collects in one place: a pool or an eddy where water swirls gently.
淀 combines 氵 (water) with 定, which likely contributes the sound and the idea of settling or becoming still, suggesting water that has settled into a pool or eddy.
Water 氵 plus 定 (settle) gives the image of water that has settled into a calm pool or a slow eddy.
For テン, picture a still pool under a tent: tent -> テン, and the water inside the tent is calm and settled.
