Can you say that unconsolidated sediments that deposited in a high energy environment like creeks and rivers possess a higher bulk density and thus a higher stiffness than unconsolidated sediments deposited in low energy environments like seas and lakes? This question originated from the geotechnical evaluation of drillings and Dynamic Penetrometer tests.
Hints for papers or other literature are welcome.
From geotechnical tests that we did on tailing storage facilities (TSFs), unconsolidated sediments deposited in a high-energy environment typically possess a higher bulk density compared to those deposited in low-energy environments. This is because in high-energy environments, such as mechanical loading in TSFs, fast-flowing rivers or areas with strong wave action, the sediments are subjected to greater compaction due to the constant movement and pressure of water or other forces. As a result, the sediments become more densely packed, leading to a slightly higher bulk density. In contrast, sediments deposited in low-energy environments,l experience less compaction and tend to have a lower bulk density.
Agree with Glen. Similar experience when comparing alluvial and estuarine sediments. The low energy estuarine sediments contain a lot of water and they are very loosely packed, therefore classified as very loose or very soft, while comparable alluvial sediments are typically firm or better. Word of warning, lacustrine and marine sediments can have a very wide range of depositional facies variations from very low energy to very high energy. Same applies to a degree to alluvial sediments: channel bed load (high energy) is typically denser than floodplain/swamp sediments (low energy).
