Morphometric Surface Dimension Analysis of Three Different Oxbow Lakes in Lubuk Siam Village

Oxbow lake is usually formed in a meandering river. Lubuk Siam village is one of the places passed by the Kampar River, which has a meander shape. In this study, there are three oxbow lakes to be studied: Lubuk Siam, Selat Panjang, and Putus. Morphometric Surface Dimension data was collected by using geographical information system (GIS). It was then analyzed using GIS data processing software. The results showed that Lake Putus has the most significant area compared to the other two lakes adjacent to each other. The size of Lake Putus is 22.99 Ha. The results showed that three of these lakes’ shoreline development index (SDI) value is less than 1. This SDI value shows that the shape of the lake is regular. The lake’s regular shape indicates the lake’s low productivity as a result of a low number of nutrient inputs.
