Abstract

The presence of fine sediment in river gravels is widely recognized as being detrimental to salmonid habitat quality. In order to facilitate quantification of sand presence at larger scales, this paper presents an application of image processing allowing for rapid and accurate assessments of superficial sand presence in dry exposed fluvial gravels. Images for the process are acquired with a 35 mm SLR film camera and then scanned with a desktop scanner. Texture-based segmentation is then applied to differentiate between sand and clast areas. Results show that the method is accurate
