Sources of suspended sediments in salt marsh creeks: Field measurements in China and the NetherlandsSun, J. (author), van Prooijen, Bram (author), Wang, Xianye (author), Hanssen, J.L.J. (author), Xie, W. (author), Lin, J. (author), Xu, Yuan (author), He, Qing (author), Wang, Zhengbing (author)Marsh creeks are perceived as important conduits for transporting water and sediment between mudflats and marshes. In order to advance the understanding of the transport mechanisms in creeks, the source and ultimate sink of sediment which moves between mudflats and marshes through creek channels need further investigation. Therefore, two...journal article 2024

Xu, Y. (author), Meng, Z. (author), Bol, R.J.M. (author), Šavija, B. (author)A novel highly compressible auxetic cementitious composite (ACC) is developed in this work. Contrary to conventional cementitious materials, such as plain concrete and fiber reinforced concrete, the ACC shows strain-hardening behavior under uniaxial compression: the stress continuously increases with strain up to approximately 40 % strain. On...journal article 2024
