Abstract
The purpose of this study is to verify LSPIV technique. Verification was made using moving cart with known velocity. The difference of velocity values obtained using these methods are within 5％, which means that LSPIV can be used in the field with reasonable accuracy After verification, LSPIV was applied to the river. The Neungwon stream and the Gonjiam stream, tributaries of the Kyungan stream, were selected as the test sites for application. The results of the test application were compared with those obtained by 3-D electromagnetic current meter and electron-wave surface velocity meter. Results show that the velocity values obtained using LSPIV coincide well with those obtained using conventional devices with maximum difference of 8％.
