Numerical flow models have become a standard tool in hydraulic engineering practice over the past decades. Rapid developments, particularly in data availability and computing power, allow and require increasingly sophisticated and complex models. This development raises the question of how the quality of modeling and its results can be adequately tested and ensured. Numerous factors and influences play a role in the process of flow modeling. These can vary significantly due to the different organizational structures of the involved institutions, the distribution of responsibilities, individual approaches, and time constraints.

The need for defined concepts for quality assurance (QA) and quality management (QM) is therefore evident. In cooperation with the DWA (German Association for Water, Wastewater and Waste), methods and concepts for quality management in flow modeling are being developed. The goal is to provide all project participants – from clients to modelers – with recommendations for quality assurance and evaluation.

As part of this research, we are conducting an international survey on the state of QA/QM in flow modeling. The aim of this survey is to identify practical requirements for QA/QM processes and the need for improved concepts. The target audience includes professionals from engineering firms, consulting companies, research institutions, and clients who are involved in or responsible for flow modeling.

We invite you to participate via the link below. The results of the survey will be published afterwards. The survey will only take around 10 min. Your participation is anonymous.

Coastal river deltas must adapt to relative sea-level rise. Sedimentation, which occurs naturally in deltas, is a key factor for successful adaptation. However, anthropogenic activities reduce sediment delivery and hinder sedimentation processes. This PhD project aims to explore the potential of sedimentation for adaptation in deltas around the world. It will assess sedimentation processes and strategies to enhance sedimentation, providing insights into the role of sediment in supporting delta adaptation.

In this PhD project, you will tackle the critical challenge of balancing hydropower energy production with competing water demands, such as irrigation and flood control, in reservoirs impacted by climate change and extreme weather events. Hydropower plays a vital role in the global energy transition, providing essential renewable energy and supporting grid balancing between supply and demand. However, its reliability is increasingly threatened by changes in water availability and the emergence of extreme conditions, such as droughts and floods, which complicate reservoir management.

Are you interested in tackling the global plastic pollution problem through science? Do you want to develop and test new measurement methods to quantify plastic pollution in rivers? Are you motivated to work on impact-oriented research in an emerging field with high societal relevance? We are currently looking for a highly motivated PhD candidate to join our team (4 years, full time, fully funded) at the Hydrology and Environmental Hydraulics Group at Wageningen University.

In this PhD research project you will develop a new method for measuring underwater plastic, by collecting and analyzing Acoustic Doppler Current Profiler (ADCP) data from experiments under (semi-)controlled, and natural conditions. You will use this to (1) detect and distinguish the most common plastic items rivers, (2) estimate total plastic transport with ADCP and validate with reference net sampling measurements, and (3) estimate trends using long-term historical ADCP datasets. You will do this for rivers in the Netherlands and Asia. You will present the project results during meetings with project partners, at (inter)national conferences, and through peer-reviewed publications.

Three PhD positions are offered at the Department of Physical Geography at Utrecht University. Are you passionate about contributing to research on climate change impacts, which are becoming increasingly urgent? The Department of Physical Geography seeks a team of three PhD candidates who will each work on a separate project:

1. Global Delta Adaptation Physical Solution Space aims to understand adaptation measures in deltas globally to climate-driven flood- risk due to sea- level rise and changes in river flows. You will work on a quantitative approach to assess the effectiveness and physical feasibility of different adaptation measures and pathways under a range of climate and socio-economic scenarios. Methods include model-based flood- risk analysis and pathways generation, which will result in an assessment of delta adaptation pathways and resources globally.
2. Rhine-Meuse Delta Adaptation to Extreme Compound Events focuses on understanding adaptation measures and pathways to uncertain compounding climate extremes such as extreme rainfall, river flow, and storm surge. You will work on modelling water management and land use change measures under scenarios involving multiple hazards for the Rhine-Meuse delta. With this model you can assess the physical feasibility of adaptation measures that work with the functioning of the natural environment (“What does the delta want?”). The research will be carried out in collaboration with Rijkswaterstaat, the Dutch government authority for public works and water management.
3. Strategies to Enhance Sedimentation for Delta Adaptation is about sedimentation in deltas as adaptation strategy to relative sea-level rise. You will explore strategies to reintroduce sedimentation to discover their potential and limitations worldwide. You will develop a generic modeling approach to quantify the effectiveness of these strategies in reducing flood risk. This model can then be used to better understand the role of sediments in delta adaptation, and their potential in combination with other adaptation measures to enhance delta sustainability.

A 4-yr PhD position is offered at the VU Earth Science Department to combine the information from dendrochronological and sedimentary palaeoflood data in NW-Europe to gain a better insight into the spatial and temporal variability of the Holocene hydroclimate – specifically that of extreme events. With your research, you make an important contribution to addressing today’s societal challenges including climate change and natural hazards. A fundamentally enhanced understanding of drivers for hydroclimatic change and natural flood variability will lead to better understanding of the unfolding effects of a rapidly warming climate.

The project main aims are to establishing if (i) dendrochronological and sedimentary data are signalling the same hydrological events and trends in riverine environments, and if these can be deployed together to improve our abilities to reconstruct the magnitudes and specific timing of extreme flood events, and (ii) whether largest floods did have a supra-regional impact, and if such events align with known periods of hydroclimatic instability or relatively warm/cold climate conditions that have been recorded in NW-Europe. The project involves fieldwork to collect novel sedimentary palaeoflood data and to investigate changes in fluvial geomorphology associated with flood regime changes of the Meuse, Rhine and Overijsselse Vecht rivers.

This project is funded by a governmental grant to stimulate independent research, and the Dutch Cultural Heritage Agency. Results will be presented at (international) conferences and peer-reviewed publications will form the basis of a PhD dissertation. The candidate will be involvement in teaching activities, such as the supervision of BSc and MSc thesis projects. We seek a candidate that is strongly motivated, has the ability to work across disciplines, and is eager to participate in dedicated research communities such as the NCR (Netherlands Centre for River Studies) and the GLOCOPH (Global Continental Palaeohydrology) working group.

Rivers of the Silk Roads: how water shaped societies and empires in Central Asia 

(Leverhulme Trust funded project) 

 

36 month PDRA (£34,304 starting salary) with expertise in remote sensing and hydraulic modelling required from September 1^st, 2022 to work with Professor Mark Macklin (University of Lincoln, UK) and Dr Willem Toonen (Vrije Universiteit Amsterdam, Netherlands)  

 

Project summary and PDRA role: The importance of Central Asia’s Silk Roads to world history is well known. But what is not understood is the role that rivers in the region played in the development of nomadic and urban societies, and empires, particularly irrigation-based agriculture but also as water-rich corridors for pastoralists and travellers. Rivers of the Silk Roads is a novel and ambitious interdisciplinary project which uses state-of-the-art dating, hydraulic modelling and satellite imaging techniques, combined with archaeological investigations of ancient canal systems, to provide the first multi-millennial length reconstructions of changing water resources and water hazards along Central Asia’s Silk Roads. The PDRA will facilitate process-based connections between short- and long-term hydroclimatic change and the dynamics of regional flood-irrigation networks in each study area. Site based reconstructions will be made of flood regime changes in order to infer water availability for irrigation. Combined with a functional analysis of irrigation-canal networks, based on remote sensing and field investigations, agricultural yield will be modelled. The PDRA, supervised by Professor Macklin and Dr Toonen, will undertake two work packages.

 

WP1. Remote sensing and mapping of irrigation infrastructure, palaeochannels and canals, alongside ancient settlement distribution. Using high-resolution, gridded dataset of Earth’s floodplains generated from Shuttle Radar Topography Mission, and declassified CORONA satellite images, the PDRA will map (GIS-aided visual interpretation) and then digitise canal networks and associated field systems. CORONA images (1960-1972; KH-4B) are easily accessible from the USGS EROS Archive, have high spatial resolution (1.8-2.7 m) and because these are amongst the earliest imagery available across Central Asia, they predate the considerable damage and loss of archaeological sites (including ancient canals and field systems) that has happened over the last 40 years as a result of agricultural and urban development. All data, including new and recorded archaeological sites, will be mapped and archived using ArcGIS with the intention of developing an open-access GIS that would be made available to researchers and heritage managers in both Central Asia and more widely. From these analyses the PDRA will establish the form and phases of irrigation infrastructure in each of the study areas, including quantitative information on canal system length and dimensions, as well as the total area of irrigated fields and how these developed and changed over time.

WP2. Hydraulic modelling of canal systems to assess the likely population size they could sustain based on irrigation-supported agricultural yield, and how this may have changed over time. The cross sectional area and slopes of canals for each phase of irrigation development will be surveyed and, using an appropriate roughness value derived from Manning’s equation, their maximum flow carrying capacity calculated. To evaluate the performance of canal networks for different time periods, with respect the volume of flow and the areas of irrigated land that they could support, the PDRA will use the US Corps of Engineers Hydrologic Engineering Center’s (2009) HEC-GeoRAS model. Average spring and summer flows from the feeder river systems based on

gauged, tree ring and palaeohydrological estimates (determined from the dimensions of feeder channels contemporary with the phase of irrigation being modelled will be numerically routed through the canal system to evaluate the performance of the canal network. This will include determining if the feeder canal was able to supply all of the secondary canals simultaneously or if it was necessary to create a schedule of rotating water delivery. The PDRA will use the United Nations FAO “CROPWAT” software, to calculate the amount of water to grow staple cereal crops and vegetables that require irrigation, and compare this with estimated flows in canal systems for each time period.

 

For further information please email Professor Mark Macklin (mmacklin@lincoln.ac.uk) or Dr Willem Toonen (w.h.j.toonen@vu.nl). The successful applicant should be available to start this post on September 1^st 2022, or very shortly after this date.
