The bernoulli effect is dependent on flow speed (as this increases the pressure differential) and mass of the grain. Based on this, could you think of how grains in an upper planar regime or a lower planar regime may be differently impacted by the Bernoulli effect (hint: look at flow speed and grain size within a given regime on the chart). The image is a graph depicting the relationship between flow speed (in meters per second) and sediment grain size (in millimeters). This graph is based on research by Southard from 1991 and considers a flow depth of 0.3 meters. **Axes:**- The x-axis represents the grain size, ranging from 0.06 mm to 8.0 mm.- The y-axis represents the flow speed, ranging from 0.2 m/s to 2.0 m/s.**Zones:**The graph is divided into several labeled areas (A, B, C, D, E, F), indicating different sediment transport or depositional environments:- **Zone A:** At the top, indicating high flow speeds across all grain sizes.- **Zone B:** Starts around 0.06 mm grain size with a flow speed of 0.8 m/s.- **Zone C:** Covers a range of flow speeds from around 0.6 m/s to 1.5 m/s and grain sizes from slightly above 0.1 mm to about 2.8 mm.- **Zone D:** Below Zone B, at lower flow speeds ranging around 0.4 m/s.- **Zone E:** A small area at a flow speed of approximately 0.4 m/s and a grain size of about 1.0 mm.- **Zone F:** Covers larger grain sizes (around 0.6 mm to 8.0 mm) with lower flow speeds below 0.6 m/s.**Interpretation:**This graph is used to understand how sediment of different grain sizes is transported at varying water flow speeds. Such diagrams are crucial for sedimentologists and hydrologists in predicting sediment behavior in rivers and other sedimentary environments.
