DREDGING ATTACHED 1.5 KM BEACH ON THE BANKS OF THE WESER

The suc­tion hop­per dred­ger HEGEMANN IV is curr­ently being used to rein­force the appro­xi­m­ately 1.5 km long “War­fle­ther Sands” in the muni­ci­pa­lity of Berne. The tidal influence and ship­ping traf­fic on the Weser have led to con­sidera­ble ero­sion in the area of the beach sec­tion in recent years. With the help of the HEGEMANN IV and flus­hing pipes, around 85,000 m³ of sand is being washed up on the shore to res­tore the beach sec­tions. The last time the sand was washed up was in 1994. 

The hold of the HEGEMANN IV con­ta­ins approx. 1,400 m³ of sand per trip, which comes from main­ten­ance dred­ging of the Weser navi­ga­tion chan­nel. The sand/water mix­ture is flus­hed onto the beach using flus­hing pipes. The sand is then spread and instal­led using a bull­do­zer. The flus­hing pipes are exten­ded step by step by 12 m long sec­tions in order to work off the entire “War­fle­ther Sand”. 

The work will be car­ried out 24 hours a day, 7 days a week. Com­ple­tion is expec­ted at the begin­ning of August.
Ano­ther sec­tion of beach in the Els­fleth area will be ref­loa­ted in sum­mer 2022.
