Gautam, K. (author), Wolf, M.E. (author), Bogaard, T.A. (author), Blom, A. (author)The dynamics of the bifurcating Karnali river in the western plains of Nepal and India is governed by the geomorphological processes in an alluvial fan. The dynamic branches showcase a notable degree of braiding, dominant channel switching and unequal discharge partitioning. Since recent switching of the dominant channel of Karnali system...abstract 2024

van Natijne, A.L. (author), Bogaard, T.A. (author), Zieher, Thomas (author), Pfeiffer, Jan (author), Lindenbergh, R.C. (author)Landslides are one of the major weather-related geohazards. To assess their potential impact and design mitigation solutions, a detailed understanding of the slope processes is required. Landslide modelling is typically based on data-rich geomechanical models. Recently, machine learning has shown promising results in modelling a variety of...journal article 2023

Tang, Yuchen (author), van Rhijn, Fay (author), Abdelrady, Ahmed (author), Foppen, J.W.A. (author), Bogaard, T.A. (author)Recently, superparamagnetic silica encapsulated DNA microparticles (SiDNAFe) were designed and in various experiments used as a hydrological tracer. We investigated the effect of bed characteristics on the transport behaviour and especially the mass loss of SiDNAFe in open channel injection experiments. Hereto, a series of laboratory...journal article 2023

Gautam, K. (author), Roebroeck, M.E. (author), Bogaard, T.A. (author), Blom, A. (author)Rivers flowing from the highlands to the lowlands, characterize the Terai Arc Landscape (TAL) in Nepal and India, but also the neighbouring region in Bhutan. The sudden change in slope results in deposition of nutrient-rich sediment, which forms large alluvial or fluvial fans that enhance biodiversity and economic activities in the region. Our...abstract 2023

Greco, Roberto (author), Marino, Pasquale (author), Bogaard, T.A. (author)Occurrence of rainfall-induced landslides is increasing worldwide, owing to land use and climate changes. Although the connection between hydrology and rainfall-induced landslides might seem obvious, hydrological processes have been only marginally considered in landslide research for decades. In 2016, an advanced review paper published in...journal article 2023

Zwart, Robert H. (author), Bogaard, Jordi (author), Kana, A.A. (author)Trim optimization improves the energy efficiency of ships, thus reducing operational costs and emissions; however, trim tables are only available for a limited number of ships. There is thus a desire to develop additional, more accurate trim tables without the need for expensive model testing. The objective of this research was to develop a...journal article 2023

Kianfar, B. (author), Hassanizadeh, S. Majid (author), Abdelrady, Ahmed (author), Bogaard, T.A. (author), Foppen, J.W.A. (author)In the terrestrial environment, interactions between natural organic matter (NOM) and colloids can lead to the formation of an environmental corona around colloids, influencing their transport behaviour and, ultimately, their ecotoxicity. We used a synthetically designed colloid tagged with DNA (DNAcol) as a surrogate for natural colloids and...journal article 2023

Mukolwe, Micah (author), Di Baldassarre, Giuliano (author), Bogaard, T.A. (author)The growing coincidence of occurrence of natural hazards and vulnerable societies, leading to economic damages and fatalities, has triggered more studies on benefits of prevention measures. This chapter describes a study that aims to demonstrate benefits of risk-prevention measures by applying the KULTURisk methodology (see Chapter 6). The...book chapter 2023

(author)Particle tracers are sometimes used to track sources and sinks of riverine particulate and contaminant transport. A potentially new particle tracer is ~200 nm sized superparamagnetic silica encapsulated DNA (SiDNAFe). The main objective of this research was to understand and quantify the settling and aggregation behaviour of SiDNAFe in river...journal article 2023

(author)Preferential flow induced by desiccation cracks (PF-DC) has been proven to be an important hydrological effect that could cause various geotechnical engineering and ecological environment problems. Investigation on the PF-DC remains a great challenge due to the soil shrinking–swelling behavior. This work presents an experimental and numerical...journal article 2023

Mapiam, Punpim Puttaraksa (author), Methaprayun, Monton (author), Bogaard, T.A. (author), Schoups, G.H.W. (author), ten Veldhuis, Marie-claire (author)The low density of conventional rain gauge networks is often a limiting factor for radar rainfall bias correction. Citizen rain gauges offer a promising opportunity to collect rainfall data at a higher spatial density. In this paper, hourly radar rainfall bias adjustment was applied using two different rain gauge networks: tipping buckets,...journal article 2022

(author)In recent years, DNA-tagged silica colloids have been used as an environmental tracer. A major advantage of this technique is that the DNA-coding provides an unlimited number of unique tracers without a background concentration. However, little is known about the effects of physio-chemical subsurface properties on the transport behavior of...journal article 2022

(author), Palmieri, Luca (author)This paper describes the implementation of an FBG sensor to measure water levels in a dike. The sensor is based on a 3D-printed mechanical transducer through which the external pressure is converted into longitudinal strain exerted on the fiber. An additional FBG integrated within the sensor measures temperature and is used to compensate for...journal article 2021
