Design a clear cutaway educational illustration of the urban groundwater cycle for middle-school students. Across the upper third, show rainfall reaching roofs, green roofs, parks, permeable pavement, and street drains. Below, reveal soil layers, tree roots, utility drainage pipes, sand and gravel aquifers, a pumping well, and a river receiving groundwater. Use simple arrows and icons to explain infiltration, surface runoff, pipe discharge, subsurface flow, pumping, and river recharge without relying on words. Compose the image in landscape 4:3 on a warm-white classroom-poster background, with polished flat editorial forms, subtle dimensional shading, generous whitespace, and a slate-blue, teal, earth-brown, muted-green palette. Keep water movement and pipe connections scientifically plausible. No readable text, letters, numbers, logos, watermark, national symbols, dense clutter, or impossible infrastructure.
