Berendrecht, W.L. (author), van Vliet, M.E. (author), Griffioen, J. (author)Quality control of large-scale monitoring networks requires the use of automatic procedures to detect potential outliers in an unambiguous and reproducible manner. This paper describes a methodology that combines existing statistical methods to accommodate for the specific characteristics of measurement data obtained from groundwater quality...article 2023

A new setup to study the influence of plant growth on the consolidation of dredged cohesive sedimentBarciela-Rial, M. (author), Saaltink, R.M. (author), van Kessel, T. (author), Chassagne, C. (author), Dekker, S.C. (author), de Boer, H.J. (author), Griffioen, J. (author), Wassen, M.J. (author), Winterwerp, J.C. (author)Dredged cohesive sediment is progressively being used for wetland construction. However, little is known about the effect of plant growth during the self-weight consolidation of this sediment. In order to check the feasibility of such a study, a new experimental setup has been constructed. As an example, the effect of Phragmites australis on the...article 2023

Bijlmakers, J. (author), Griffioen, J. (author), Karssenberg, D. (author)Disturbance-dependent grasslands, often associated with hydromorphological and fire dynamics, are threatened, especially in subtropical climates. In the Nepalese and Indian Terai Arc Landscape at the foot of the Himalayas, natural and cultural grasslands serve a viable role for greater one-horned rhinoceros (Rhinoceros unicornis) and for grazers...article 2023

Schot, P. (author), Beard, J. (author), Hissink, R. (author), Silberbauer, M. (author), Griffioen, J. (author)Ecological values of water have gained increasing attention over the past decades in both (eco)hydrological research and water resources management. Water quality is an important ecological steering variable, and graphical water quality diagrams may aid in rapid interpretation of the hydrochemical status of a site. Traditionally used water...article 2022

Islam, M.F. (author), Schot, P.P. (author), Dekker, S.C. (author), Griffioen, J. (author), Middelkoop, H. (author)The Ganges–Brahmaputra–Meghna delta in Bangladesh is one of the largest and most densely popu lated deltas in the world and is threatened by relative sea level rise (RSLR). Renewed sediment deposition through tidal river management (TRM), a controlled flooding with dike breach, inside the lowest parts of the delta polders (so called beels) can...article 2022

Barciela-Rial, M. (author), Vardon, P.J. (author), van Kessel, T. (author), Griffioen, J. (author), Winterwerp, J.C. (author)Progressively, more dredged sediments are being reused for engineering projects. For example, the Marker Wadden is a new wetland constructed in lake Markermeer, the Netherlands, with dredged cohesive sediments originating from the bed of the lake. Such dredged sediments are often dominated by cohesive sediment particles with varying amounts of...article 2022

Tidal river management (TRM) as practiced in coastal regions of Bangladesh may provide an opportunity to combat RSLR by...article 2021

In the Khulna and Satkhira districts, Bangladesh, pond water is pathogen-contaminated, while groundwater from shallow tubewells may be arsenic- or saline-contaminated.

Naus, F.L. (author), Schot, P. (author), van Breukelen, B.M. (author), Ahmed, K.M. (author), Griffioen, J. (author)In southwestern Bangladesh, clean drinking water is scarce, since rainwater is only available during the monsoon, pond water is often bacteriologically polluted, and groundwater may exhibit high salinity and arsenic levels. Managed aquifer recharge (MAR) might potentially provide safe drinking water by storing abundant freshwater from the wet...article 2020

Foredunes are replenished with sand from the beach and can be transported further into the dune area.We investigated whether nourishment material alters the phosphorus (P) content of dune soil and the nitrogen (N):P ratio of dune vegetation in two areas: a mega...article 2020
