In this study, monitoring the nourished sand longshore movement was conducted based on the feldspar luminescence measurement, including both Thermoluminescence (TL) and Optically Stimulated Luminescence (OSL). Nourished sand presents larger TL/OSL properties than the natural beach sand. Investigation on the spatiotemporal distribution of post-filling beach sand luminescence features at the Miyazaki coast and the Shounan coast, Japan, provides a new approach to evaluate the nourished sand

Comparing these two techniques, it is confirmed that the OSL is suitable for study on short-term sediment movement within a limited area; whereas, TL can be applied to the long-term and large-scale nearshore process assessment. Recently, Rink (1999) and Liu et al. (2009a, b) suggested the use of natural residual thermoluminescence properties of quartz and feldspar grains as a
