Abstract: An artificial gate located at the mouth of the Geum River in Korea is operated to discharge freshwater irregularly to the coastal sea depending on the reservoir water level during the ebb time. It controls the regions of freshwater influence along with generating the salinity front. In order to manage such a coastal bay to sustain environmentally sound conditions, monitoring or field observations are necessary. For the operation of long-term monitoring or cost-effective field measurement, the deploying locations of the monitoring or sampling equipment's should be determined reasonably to represent the whole characteristics of the bay. However, no standard method to determine the optimal locations of monitoring or sampling has been proposed so far. Therefore, this study demonstrates how an objective analysis method with an inverse distance weighting function can be used to draw salinity maps from several points which can be used for optimized monitoring and sampling locations
