Abstract: There is a need for simple, inexpensive and effective means for streambank protection and fish habitat enhancement. Initial results are presented of laboratory research on the performance of gabion structures used as groins for streambank protection and fish habitat enhancement in small streams. Qualitative study of flow patterns and streambed scour patterns associated with various arrangements of gabions was undertaken. Single gabions with length-to-channel-width ratios of 1:2 are discussed here. Results are found to be in agreement with a field study.
