| Summary: | This paper presents a brief analysis on the fluvial islets hydrodynamic shape. Proposed by the Wyrick (2005) and Wyrick & Klingeman (2011), the hydrodynamic shape criteria refers ”to the subaerial planform shape of the river islets”. According to them, these geomorphological landforms can have a streamlined shape, an angular aspect or irregular shape. Except for the last category, each of the other types has several subtypes. For this case study we selected the fluvial islets from the Danube River, the sector situated between Giurgiu and Oltenita towns. It can be observed that, nowadays (2017) there are five new islets unlike between 1889 and 1916 and most of the river islets have an irregular shape. Also, in the literature it is mentioned that there might be a connection between the shape and age of islets. So, in our study, we applied a Chi-Square Test to check this relation. The results show that there is a possible association between the shape and the age of the Danube's Islets. |
