Abstract

A 2D Hec-Ras flood model is established at the middle reach of the River Wye, from Ross-on-Wye to Monmouth, along the English-Wales border. The flow conditions during Strom Dennis, which occurred on 15-16 Feb 2020 are used to simulate the flood extents in the study area. The flood hazard rate, suggested by EA, is analysed to assess the risk level of flooding in the area. The results show the extensive flood extents at the study site. The flood hazard rate map shows that large part of Wye Valley is at high risk of flooding.
