  • Hyperpycnal Over Density Flows And Deposits Journal Of

    jun 19, 2020 hyperpycnal flow forms when a relatively dense land-derived gravity flow enters into a marine or lacustrine water reservoir. As a consequence of its excess of density, the incoming flow plunges in coastal areas, generating a highly dynamic and often long-lived dense underflow. depending on the characteristics of the parent flow and basin salinity, the sedimentary rocks are formed from the broken remains of other rocks that become joined together. the weight of the sediments on top squashes the sediments at the bottom. this is called compaction
