Fluvial terraces provide geochronological archives, preserving records of previous morphological processes and environmental changes. However, for the South of Taiwan, the timing of possible environmental changes and the subsequent formation of fluvial sediment deposits is still unclear. This master thesis paves the way for a wider research project which will look at coastal development and the sediment dynamics of the Hengchun Peninsula, in southern Taiwan. It does this by testing on a small catchment scale the suitability of using optically stimulated luminescence (OSL) dating methods for the south of Taiwan. This study reconstructs the morphological development of the Gang-Ko river basin, which is situated on the eastern Hengchun Peninsula, by using a combination of remote sensing methods, OSL dating, and radiocarbon dating as a means of independent age control. Five OSL samples and three radiocarbon samples were collected from four sites. For the OSL samples, a Post-IR blue OSL signal was measured. The OSL and radiocarbon age results provided a coherent chronology for reconstructing fluvial sediment aggradation in the Gang-Ko river basin: the OSL and radiocarbon ages indicated two phases of terrace aggradation since the Early-Middle Holocene at 8.0 ka and at 0.4 ka. The results, combined with the available paleoclimatic record suggest that the formation of the older terrace levels (8.0 ka) may be correlated with the Nanhuta glacier advance, a glaciation period which occurred in the high mountains of Taiwan at about 8.9 0.5 ka. During this cold phase, an increase of physical weathering and an abundance of sediment release may have favoured fluvial terrace aggradation. The results, and data on Taiwans historical development, show that the formation of the younger terrace levels (0.4 ka) is contemporaneous with significant historic land use changes caused by the arrival of Dutch sailors and Chinese migrants to Taiwan in the mid-1630s. However, a causal connection between these two events and fluvial terrace aggradation remains to be proven. The results of the remote sensing suggested recent channel deepening that may have been caused by recent flood engineering and sediment retention in the hinterland. However, the lack of high resolution hydrological data means that this last suggestion cannot be fully evidenced.
