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 movement characteristics. 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

A decrease in the RLP can be predictive of appositional closure for narrow-angle eyes under dark conditions.

In this study, monitoring the nourished sand longshore movement was performed based on the feldspar luminescence measurements, 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 provides the opportunity for assessment on the nourished sand movement characteristics, which was demonstrated from the present field studies along the Miyazaki coast and Shounan coast. Comparing these two techniques, it was found that the OSL technique is suitable for study on shortterm sediment movement within a limited area; whereas, TL technique can be applied to the long-term and large-area nearshore process estimation.
