Display a simple rock step or waterfall as an obstacle prompts

5 months ago

Minimalist schematic illustration in flat design, showing a river with a natural barrier that negatively affects fish migration. Display a simple rock step or waterfall as an obstacle. Show blocked fish with simple arrow symbols and indicate fragmentation or stagnant water zones. Use a side cutaway view or simplified flow diagram. Visual style should be very reduced, using mostly black and white with only small red or grey accents to highlight problems. Designed for an educational science poster — the image should be supportive, not visually dominant.
