I'd like to know if these forces are only at the surface and if they become worse with speed or less with speed.

Kach,
Waayyy to many questions without context: speed of the boat, speed of the water (river), with current, up current and all the combinations inherent.
Then add rocks, drops and turns, mulitply by above because "hydraulics" come into play depending on the speed of the current, depth of the water and shape of the riverbed.
I've been kayaking for almost 40 years, owned a rafting company in the late 70's...the force has been with and without me.
Edit: I have also been the Officer of the Deck (OOD) during replenishment operations between two very large ships within 120-140 FEET of each other. The suction action tries to force the two ships into each other...you can see my little helo on the back of the ship on the left.
