Reliable Sediment Measurements

We know how important it is to base prediction and design upon sound field investigation. ENVIROMUD specialises in determination of site-specific characteristics, properties and behaviour of sediment. These allow evaluation of parameters that govern sediment transport behaviour and patterns. Measurements are key to provide a real world understanding of local sediment behaviour and can then be used to make informed analysis, decisions and modelling.

Bed Sediment Properties

  • Particle Size Analysis (PSA) – gravimetric sieving and pipette analysis
  • Bulk Density, Dry Density
  • Sediment Erodibility - shear strength, critical erosion shear stress (in-situ, on grab samples, or box cores)
  • Chemical Constituents - pollutants, Organic Carbon, Nitrogen, Heavy Metals, Chlorophyll etc. (external analysis)
  • Benthic Fauna– wet sieved macrofauna (external analysis)
  • Sedimentation Parameters ( e.g. settling velocity)
