- Abstract
Sandbar is one of river structures that functions to decrease river flow velocity and increase diversification of flow distribution leading to river channel stability. Sandbars have roles in sediment transport mechanism, reducing pollutants due to denitrification mechanism, and as a host for aquatic organism. However, the researches on sandbars’ geometry, resistance to flow, sediment transport, and the correlation with aquatic ecosystem are relatively lacking. Based on these problems, this study aims to identify geometric characteristics of sandbars in Progo River as preliminary understanding of sandbar. The research will be conducted by measuring geometry of sandbars using satellite imagery such as sandbar length (p), sandbar width (l), river width (L), and distance of sandbar from riverbank (d), then proceed with calculating the ratio of p/l, L/l, L/d, and L/p. The importance of each ratio and the comparation to island geometry is presented in the results and discussion. The results show that the characteristic of geometry of the 47 sandbars found in Progo River are p/l = 1.39–5.51, L/l = 1.48–11.72, L/d = 1.61–7.00, and L/p = 0.65–5.45. The benefits of this research are to provide reference regarding the characteristic geometry of sandbar and its implications in river development and conservation.
