Project Description:

Wetlands play a crucial role in hydrological and ecological systems, providing essential services such as flood regulation, and biodiversity support. Accurate predictions of seasonal wetland flooding are critical for managing these valuable resources and understanding their response to climatic and hydrological variability.
Numerical hydrological models can capture some aspects of wetland flooding well, but have room for improvement. At the same time, more and more satellite-based observations of wetlands, are becoming available. This project will compare outputs from an existing flood model with various satellite-derived observations, to help assess strengths and weaknesses of the model in capturing observed wetland dynamics.

The intern will work with a multidisciplinary team to evaluate the performance of hydrological model in simulating inundation over East Africa and explore observation-based methods to refine model outputs. The research will serve as a foundational step toward improving inundation models, helping to address challenges in representing large, persistently inundated wetlands. This project is an excellent opportunity for students with a background in environmental science, physics, mathematics, computer science, or engineering to develop practical skills in model analysis, satellite data use, and scientific communication.

Tasks:

• Analyse and visualize pre-prepared model output datasets for a selected wetland region in Africa.
• Compare model predictions of wetland water extent with satellite-derived flood extent data (e.g., from Sentinel-1 or MODIS satellites).
• Test a variety of metrics for evaluating the agreement between model outputs and satellite observations.
• Perform sensitivity analyses to identify key parameters or factors influencing the model’s performance.
• Prepare a presentation and a concise technical report summarizing the methodologies, results, and recommendations.

Expected Outcomes:

• A better understanding of the strengths and weaknesses of modelled inundation outputs for the selected case study, along with recommendations for optimizing the model for future applications in regional inundation forecasting.
• The candidate will gain hands-on experience using satellite-derived flood extent products to evaluate and validate a hydrological model, developing critical skills in satellite data analysis.
• A comprehensive presentation summarizing the methodologies, results, and implications for improved flood and inundation management.

Required Skills and Background:

• Strong numerical skills, analytical and communication skills.
• An interest in hydrology, environmental science, or a related field.
• Experience with data analysis.
• Familiarity with programming languages such as Python or R. Experience with a Linux environment would also be beneficial but is not essential.

Project Description
Commercial Microwave Links (CMLs) between base stations form the basic infrastructure of mobile phone networks used ubiquitously across the world. Signal attenuation due to precipitation is routinely compensated for by mobile phone operators – providing the opportunity for these links to be used as precipitation sensors. The high resolution of the link data can provide useful precipitation estimates as a complement to more conventional sensors such as raingauges and weather radar, especially where these may be sparse or subject to error. Urban areas and remote mountainous environments often have potential to benefit from use of CML data. Arguably, the greatest challenge is gaining access to CML data from the commercial companies running the mobile phone networks.  

In summer 2024, the mobile phone operator Vodafone began a pilot study to collect and make available CML precipitation estimates from across its UK network. These include blended estimates incorporating weather radar and raingauge data. The Hydrological Forecasting Group at UKCEH has developed several hydrological models used in operational flood risk forecasting and are interested in exploring the potential uses of these CML-derived data in this context; and as part of an ongoing collaboration with the National Centre for Atmospheric Science (NCAS) Radar Group on improved space-time precipitation estimation.  

An initial step is to systematically assess the accuracy of the CML precipitation estimates by calculating various measures of the error compared to a raingauge “Truth”. How does the accuracy compare to estimates from weather radar or raingauge interpolation? Are there situations where the CML-based estimates are more or less accurate? How dense is the network of links and how does this impact on accuracy at grid- and catchment-scales? What quality control has or could be performed? How does the path-integrated nature of the precipitation estimate (between base stations separated by several km) affect the accuracy? How can such data be best interpolated in space and time? Is there anything of value in the raw data?  

Depending on research outcomes, this initiative could inform future use of CML data in operational flood risk forecasting, in the Flood and Drought Research Infrastructure (FDRI) project, and lead to peer review R&D publications.

Project Description
The Sixth Assessment Report of the Intergovernmental Panel on Climate Change highlights that the sustainability of many communities worldwide could face significant threats due changes in hydrological extremes (i.e., floods and droughts) and the transitions between them. Understanding observed and future trends and variability of water resources at the global scale is crucial for informing climate change adaptation. However, hydrological trends are often confounded by human disturbances, such as dams, abstraction for irrigation or domestic/industrial water use. The ROBIN project has assembled a global Reference Hydrometric Network (RHN), consisting of 3000+ near-natural catchments with quality-checked river flow measurements, some stretching back to the early 20th century. While studies have investigated the effects of large-scale climate variability on river flows, few studies have attempted to disentangle the complex influence of climate variability on hydrological regimes at near-natural catchments at the global scale.  

UKCEH researchers have begun analysing the river flow observations within the ROBIN dataset to identify trends in low flows and hydrological droughts. This project aims to expand recent analysis to characterise general river flow and flood variability, identify the influence of different modes of climate variability on flood regimes and characterise transitions between floods and droughts. The project will have collaborations and expertise from scientists within UKCEH and beyond. The specific objectives of this project are to: 

• Characterise seasonal river flow variability across all ROBIN catchments   
• Identify flood events and transitions between extreme flood and drought events at near-natural river catchments and compute observed trends in flood and transition metrics following established trend detection frameworks (e.g. ROBIN code library) 
• Understand statistical relationships between river flows and modes of climate variability (e.g. El Nino Southern Oscillation, Atlantic Multi-decadal Variability) at varying time lags 

The output of this project will expand our understanding of global flood variability and contribute to evidence that would provide baseline data to help constrain future river flow and flood projections. During this project, the student will gain an understanding of hydro-meteorology, established trend detection methods, R/python programming and a flavour of academic research.

The successful candidate for this project should possess: 

• Strong numeracy/statistical skills and effective oral and written communication abilities. Proficiency in the Python/R programming language is essential 
• Candidates should either hold or be actively pursuing an undergraduate degree in earth/environmental sciences or a related scientific discipline.  
• Some experience using high-performance computing (HPC) would be beneficial, but not mandatory.

Water resource modelling is an area of growing significance, as a combination of climate change and population growth places increased pressure on limited freshwater resources. Key aspects of modelled water resource management (WRM) include: water withdrawals from ground and surface water sources to meet water demand (domestic, industrial, and agricultural); return flows; water transfers; and managed reservoirs. Including these processes in a hydrological or land-surface model has several benefits: it allows water resource assessments to be undertaken; the impact of anthropogenic influences on the hydrology can be explored; and simulated stream flows in heavily influenced catchments become more realistic.

Many large-scale gridded models have WRM modules, including WaterGAP [1], VIC [2], H08 [3], LPJmL [4], PCR-GLOBWB [5], WBMplus [6], GWAVA [7], CWATM [8], and, recently, JULES. These models are often run at a coarse spatial resolution, for example, our team has implemented JULES-WRM at 0.5◦ resolution over Brazil. The next challenge is to further develop the models and datasets necessary for water resource modelling at a finer spatial scale [9, 10, 11, 12, 13], so that more detailed information on water demand and availability can be provided to water users and policy makers.

Within Hydro-JULES, we are building on the current WRM functionality within the JULES model, refining the WRM module to address the coarse scale assumptions and making use of new datasets to ultimately model water resources in the UK at a 1km × 1km resolution.

In this project, initial model outputs (utilising new datasets and existing model functionality) will be explored. The objectives of this project are:

• To compare simulated stream flows with observed data from the National River Flow Archive (NRFA) [14] (for model runs with and without WRM) to determine the impact of anthropogenic influences on stream flow over England.
• To compare simulated water withdrawal for irrigation (as calculated within the JULES model) to estimates from the new abstraction dataset (citation), to estimate the validity of the JULES irrigation scheme in England.
• To identify potential limitations with the current WRM module which will inform the development of a high-resolution WRM module.
• Depending on time, there is scope to extend the project according to the interests of the student, e.g. to compare additional model outputs to observed data (soil moisture, groundwater level, etc.) to understand the impacts of anthropogenic influences on the wider hydrological system; or to explore the effects of different parameter choices within the WRM module.

A successful candidate will have:

• Experience in using a scientific programming language for data handling and visualisation (e.g. Python or R).
• Some experience in statistical methods for assessing goodness-of-fit.
• Knowledge of the hydrological system, ideally including anthropogenic influences.
• Good numerical and oral/written communication skills.
• The candidate will gain an understanding of water resource modelling; experience analysing spatial and time-varying data; and develop key research skills including communicating science.

Project Overview
The intern will use the British Groundwater Model or BGWM ( see www.bgs.ac.uk/geology-projects/environmental-modelling/british-groundwater-model/ ) to examine how droughts propagate in groundwater systems.  Working at a national scale they will focus on particular basins across Britain to understand how groundwater droughts have developed in the past.  
They will explore what might happen from differing starting conditions based on simulating historic groundwater droughts, e.g. 1975/6.  From this understanding creates a series of scenarios which can be used to understand how groundwater droughts are initiated and how they propagate across the selected basins. 
 
Intern Tasks and Outcomes

• Familiarity with running the British Groundwater Model. 
• Identify historic groundwater droughts.
• Create scenarios to examine groundwater drought events, how they start and how they propagate through the system.
• Examine the starting conditions for each drought and what this means for the drought development and propagation in the basin.

The ideal candidate will have the following skills:

• A background and understanding of groundwater systems.
• Groundwater modelling experience, particular USGS MODFLOW groundwater codes or similar groundwater modelling frameworks.
• Proficiency in data processing.
• Proficiency in Python.
