The Naruse River mouth was one of many coastal and estuarine areas destructed severely by the 2011 Tohoku Tsunami. Under the intense impact of the tsunami, the sandspit of the Naruse River mouth was forced to disappear leaving the estuarine entrance wide open. Afterwards, almost 7 years after the sorrowful catastrophe, the following recovery of the sandspit was not able to happen due to the insufficiency of sediment supply. This was caused by the blockage of longshore sediment transport that the existing North side T-headland has been creating and the ineffective sediment supply from the river. As the river mouth is wide and clear, waves have no obstacles to approach furtherly upstream and influence inside the river, particularly, the upstream sediment deposit. However, with the desire to regain the sandspit as it was before the tsunami, an artificial sandspit was implemented by utilizing the sediment deposited inside Kitakami canal in early 2018 and has become fairly stable thus far. The morphological change of Naruse River mouth before and after the tsunami is analyzed thoroughly by multiple sources of monitoring photos obtained from 2002-2018. Several quantities of Naruse river mouth are detected in order to reflect detailed recovery process in this area.
