Danube Floodplain

KU217 delivered a study for the DANUBE FLOODPLAIN project to Croatian Waters (Hrvatske vode) on 12th August 2020. The study applied Flood Evaluation Matrix – FEM Approach (Habersack, H. et al. 2015) on the 12 active floodplains (AFP) on the rivers Sava and Danube in Croatia.

The work included statistical flood frequency analysis, hydraulic modelling (HEC-RAS model of c. 500km of Sava River through Croatia was used), calculation of FEM parameters and prioritization of floodplains for restoration for Sava and Danube. KU217 also gave comments and recommendations on further automation and standardization of the FEM methodology.

Sava River AFP’s

Six active floodplains were analyzed on the Sava river. All six floodplains need to be preserved, and priority for restoration was determined. Figure on the left shows example of FEM maps produced for the Zagreb flood defense system.

Danube River AFP’s

Six active floodplains were analyzed on the Danube river. Similar as for Sava river, all six floodplains need to be preserved. Priority for restoration was determined for all six AFP’s on Danube in Croatia. Figure on the left shows example of FEM maps produced for the Vukovar floodplain.

Windfarm Culvert Inspections in Co. Donegal

In June 2019 our Team Surveyed and inspected 26 culverts and Small Bridges to access the hydraulic capacity of the same. The work is carried out on Windfarm in Co. Donegal, Ireland. For the bridges that did not satisfactory hydraulic capacity and any new bridges we conducted Section 50 Applications.

Flood Risk Assessment using HEC-RAS 1d-2d model for River Stick estuary in Ireland

In 2018 our Team was collaborating on a small-scale modelling project. The objective of the project was to access the Risk of flooding for the site in Belgooly town proposing the development of 15 dwellings.

The assessment included fluvial flooding and also tidal flooding. Due to lack of data, tidal levels were measured on site. HEC-RAS model successfully demonstrated sources of flooding with high level of detail as shown in the video below.
