Yang, F. (author), Fu, Dafang (author), Zevenbergen, C. (author), Boogaard, Floris C. (author), Singh, Rajendra Prasad (author)Evaluation of the hydrological performance of grassed swales usually needs long-term monitoring data. At present, suitable techniques for simulating the hydrological performance using limited monitoring data are not available.

Chowdhury, Sraboni (author), Akpinar, Derya (author), Nakhli, Seyyed Ali Akbar (author), Bowser, Marcus (author), Imhoff, Elizabeth (author), Buisma-Yi, S.C. (author), Imhoff, Paul T. (author)Urban development often results in compacted soils, impairing soil structure and reducing the infiltration and retention of stormwater runoff from impervious features. Biochar is a promising organic soil amendment to improve infiltration and retention of stormwater runoff. Soil at the disconnection between impervious and pervious surfaces...journal article 2024

Flessati, L. (author), Vecchia, Gabriele Della (author), Musso, Guido (author)Cement-bentonite cut-off walls are commonly employed in geoenvironmental applications to limit ground water flow and pollutant transport. The wide diffusion of this artificial material in the current practice is not only due to its low permeability, but also to its simplicity of use. In this paper, experimental evidences about the role of...journal article 2023

van Leer, Martijn D. (author), Zaadnoordijk, Willem (author), Zech, Alraune (author), Buma, Jelle (author), Harting, Ronald (author), Bierkens, Marc F.P. (author), Griffioen, Jasper (author)Aquitards are common hydrogeological features and their hydraulic conductivity is an important property for various groundwater management issues. Predicting their hydraulic conductivity proves challenging, given its dependence on numerous variables. In this study, the dominant factors for predicting aquitard hydraulic conductivity are...journal article 2023

Yang, F. (author), Fu, Dafang (author), Zevenbergen, C. (author), Boogaard, Floris C. (author), Singh, Rajendra Prasad (author)Saturated hydraulic conductivity (K<sub>s</sub>) of the filler layer in grassed swales are varying in the changing environment. In most of the hydrological models, K<sub>s</sub> is assumed as constant or decrease with a clogging factor. However, the K<sub>s</sub> measured on site cannot be the input of the hydrological model directly....journal article 2023

Schoenmakers, Max (author)This research is aimed at creating a generic design method for infiltration drywells on sandy soils by acquiring knowledge on the functioning of these wells. Infiltration drywells are vertical infiltration pipes that are installed above the groundwater table and through which stormwater is drained to the subsurface. Infiltration drywells can...master thesis 2022

Yang, F. (author), Fu, Dafang (author), Zevenbergen, C. (author), Rene, Eldon R. (author)Stormwater biofiltration systems (SBS) are a popular technology for mitigating the negative effects of urbanization on the hydrological processes and water quality in urban areas. However, little is known about SBS's long-term performance in actual field conditions. The findings of a review of the scientific literature on the long-term...review 2022

(author)Within the framework of the Dutch sustainable landfill project iDS, four compartments of the Dutch landfill Braambergen have been treated by in-situ aeration since 2017. The aeration infrastructure comprises 230 wells with a spacing of 15 to 20 m, distrib-uted over an area of around 10 ha, intercepting a waste body of 1.2 × 10<sup>6</sup> t...journal article 2022

Kaptein, Milou (author)The control of infiltration and seepage of water is one ofthe most challenging tasks in water management and civil-engineering and, inan attempt to control this, methods for forming a waterimpermeable layer inthe soil have been widely practised in soil engineering (Laumann et al., 2018;Proto et al., 2016). The use of...master thesis 2021

Ramphal, Vanisha (author)Cement-Bentonite (CB) walls are low permeability vertical cut-off barriers that are mainly used to prevent groundwater flow and isolate contaminated areas. The hydraulic performance of the CB walls depends on the flow rate (discharge) through the wall. Therefore, the walls must achieve very low hydraulic conductivity. Poor...master thesis 2020

Azizi, Arash (author), Musso, Guido (author), Jommi, C. (author)Soils used in earth construction projects are mostly unsaturated, and they undergo frequent drying–wetting cycles (repeated hydraulic loads) due to changes in climatic conditions or variations of the ground water level, particularly at shallow depths. After compaction, changes in water content can significantly influence the hydromechanical...journal article 2020

Noordam, A.F. (author)For decades, researchers try to model the subsoil as accurate as possible in order to make cost-efficient and safe geotechnical decisions. A troublesome aspect in modelling of the soil is to determine the heterogeneity within the soil, as this is usually associated with a great deal of uncertainty. Delft University of Technology used a recursive...master thesis 2016

Liu, K. (author), Hicks, M.A. (author), Vardon, P.J. (author), Jommi, C. (author)Piping has been attributed as a major cause of dam and embankment failures. Current national prediction models to predict piping use the hydraulic gradient between the upstream and downstream water levels as an indicator. They are deterministic and take no account of preferential pathways. However, piping usually initiates from a discrete...conference paper 2015
