•Ship’s speed- More the speed more the squat & lesser the speed lesser the squat.
•The Trim of the Ship- If a ship is having a trim, the ship will squat by deeper end regardless the shape of the hull.
•Cb ( >0.7 )Box like ships will squat by head. E.g. Tankers, Bulk Carriers Where as streamlined ships will squat by stern. E.g. Container ships, Battle ships. Higher the (Cb), higher the squat.
•The draft to depth ratio-If it is 2, there is negligible squat.
•The narrowness of the channel or cannel-In narrow channels side water to the ship is less, so void created by ship will be filled by below water so the ship will squat more.
In shallow waters -  Squat = 2(Cb x V2)/ 100
