This Sea, between the Bohai Sea and the East China Sea, has a maximum depth of 103m and an average depth of 44m. The Bohai Sea is a shallow bay area north of the Yellow Sea. The East China Sea is between the Yellow Sea and the Ryukyu Islands. The division between the East China Sea and the Yellow Sea is not definite, but is often taken to be from the mouth of the Yangtze River to Saishu Island off of Korea.
Several rivers influence the Yellow Sea.
The Yangtze River and the Yellow River are the two largest. There are three much smaller rivers that input into the Yellow Sea that have a relatively insignificant effect. They are the Han, the Liahoe, and the Yalu. This corresponds to the steep pressure gradient between the Siberian High, which covers most of the Asian continent, and the Aleutian Low, which covers the northern most section of the Pacific Ocean. These winds effect the local ocean currents.
