Deposition patterns around buildings at the beach: Effects of building spacing and orientation

Airflow at the beach creates sand deposition patterns around buildings. To assess how initial depend on orientation of a building relative to wind direction and spacing between buildings, series one-day field experiments was conducted with cuboid scale models, in which 34 configurations were tested. Scale models placed further apart than 2 3 times width created that similar those for stand-alone where downwind tails sum individual buildings' effects these overlapped. For smaller spacings, 0.5 width, fundamentally differed from indicating different type airflow developed This more complex depositional depended gap width. Rotation an induced asymmetry patterns. A new rule thumb quantitatively relates length behind angle length:width ratio building.
