What Happens When a RIVER Meets the OCEAN?

I have never seen water at a river mouth rise so quickly! First Rain of the season in California and sand dam at Doheny Beach was breached. The force of the water created an incredibly strong current and some powerful standing waves. The first intense rain event of the season and the San Juan Creek mouth was breached! It all starts with just a small trickle of water that begins to flow over the Sand Berm that is holding the rising water back. Witness the force of nature as the water surges through the area erodes the beach and forms a very powerful rip current
