wharf
埠 centers on a landing place by water: a wharf or pier where boats dock to load and unload.
埠 combines 土 (earth, ground) with 阜, which likely contributes the sound and relates to a mound or embankment. Together they suggest an earthen landing place.
The left side 土 is earth, and the right side 阜 looks like a piled-up mound or embankment. Picture an earthen platform built out into the water: that's a wharf.
For フ, imagine a wharf where you can hear the sound of the wind: "foo" (フ) as it blows across the dock.
