Abstract: Turbidity currents are gravity currents, where the denser fluid is a result of suspended granular materialIn fluvial hydraulics, such currents are encountered if a sediment-laden discharge enters into a reservoir. Their characteristic features are a distinctive raised head, followed by a quasi-uniform flow region called body as shown in the definition sketch of Fig.1. A turbidity current on a mobile bed may change its buoyancy flux by eroding or depositing sediment; thus, it is referred to as a non-conservative gravity current, in contrast to conservative gravity currents where the density difference is due to the presence of dissolved substances or a temperature difference and the buoyancy flux is constant.
