Initiatives on engineering solutions for Cua Tung and the northern beach of the estuary in Quang Tri province

Abstract

Cua Tung estuary is one of the largest estuaries of Quang Trị province in Central Vietnam. The beach here is beautiful and well-known for tourist in the past. But it has been eroded thus reducing tourist attraction. Cua Tung estuary serves as an important waterway, flushing out floodwater from Ben Hai river to the sea. The complexity of hydrodynamic regime in Cua Tung estuary and vicinity area is a main driver to cause high variation on erosion and sedimentation. Erosion occurs in the north beach area leading to reduction of open space for tourist, meanwhile deposition accumulates in the south beach area of the Cua Tung estuary. The paper provides some initiatives on engineering solutions for Cua Tung estuary area and rehabilitating measures in the northern tourism beach of the estuary
