Zheng, X. (author), Jiang, N. (author), Zheng, Huaili (author), Wu, Yuyang (author), Heijman, Sebastiaan (author)One framework type of high-silica zeolite only can effectively remove a limited range of organic micropollutants (OMPs) from water. In order to extend the OMP removal range, different types of high-silica zeolites need to be combined in the adsorption process.

(author)Intertidal shoals are pronounced morphological features found in many estuaries worldwide. Apart from maintaining an ecologically unique intertidal environment, shoals also protect adjacent dyke systems by attenuating waves. The fate of sandy shoals under anticipated sea level rise (SLR) scenarios is underexplored. The current research...journal article 2021

Jia, Yueyi (author), Zheng, Feifei (author), Zhang, Qingzhou (author), Duan, Huan Feng (author), Savic, Dragan (author), Kapelan, Z. (author)Hydraulic modeling of a foul sewer system (FSS) enables a better understanding of the behavior of the system and its effective management. However, there is generally a lack of sufficient field measurement data for FSS model development due to the low number of in-situ sensors for data collection. To this end, this study proposes a new method...journal article 2021
