  Spatial sedimentological characteristics of surface and shallow intertidal sediments at an estuary-beach system (using the Hayle-St Ives system as a case study) is presented in this study. Short sediment cores obtained from 80 samples are sliced at 1cm intervals and the grain size analysis is undertaken on these subsamples, using a Malvern MasterSizer 2000. The resulting distributions are processed to yield a range of grain size statistics through the GRADISTAT software package. Grain size parameters are examined to explore the evidence for the system’s sediment mixing and extensive sediment transport processes. Sediment statistics at the coastlines/beaches (Carbis Bay, Black Cliff and Godrevy Towans) show that sediments are well sorted, near symmetrical/positively skewed medium-coarse sand while the inner estuary samples are predominantly medium sand, well sorted, symmetri..
