Lead Research Organisation:
UK CENTRE FOR ECOLOGY & HYDROLOGY
Department Name: Hydro-climate Risks
Abstract
The major project outcome will be a world-leading integrated terrestrial hydrological model that goes from global weather and local rainfall through the terrestrial hydrological system to flood inundation assessments and their consequent impacts. The Hydro-JULES model and its associated datasets will enable UK science to tackle outstanding research questions in hydrological science and will provide a national resource to support research both specific to the Hydro-JULES project and beyond. Hydro-JULES will provide the UK hydrological and land-surface communities with the model and research infrastructure to tackle the most pressing internationally-important research questions in this field, which include:
1. How do hydrological systems respond to present-day climate variability and how can the impacts of future climate change best be quantified in ungauged locations, in data-sparse regions and under non-stationary conditions?
2. To what extent can new observational and modelling techniques improve our understanding of how extreme precipitation, especially high-intensity convective precipitation, drives flooding?
3. How will changes in land-use and land management affect surface permeability, soil water storage, runoff, river flows and flood inundation?
4. What are the combined probabilities of fluvial, pluvial, coastal and groundwater flooding in response to changes in climate, and can a coupled approach to flood risk estimation quantify those risks more effectively?
5. How will biogeochemical and nutrient cycles respond to current and future variability in the hydrological cycle, especially under conditions of changing climate and land-cover?
6. To what extent can assimilation of observed hydrological states and fluxes (e.g., soil moisture and stream flow) improve hydrological and meteorological predictions, and on what time-scales?
7. Can uncertainty in large-scale hydrological predictions be attributed to specific hydrological processes in order to target future process-based research?
8. What is the sensitivity of Earth system components (e.g., vegetation, carbon cycle, aerosols, land ice, sea ice, ocean circulation and biogeochemistry) to changes in the hydrological cycle; and can enhanced representation of terrestrial hydrology in Earth system models help constrain responses to such changes?

Planned Impact
Impact is expected to be widespread across policy and industry. Hydro-JULES will help to improve the underlying models and information that informs flood prediction and estimation and should ensure more accurate and timely flood warnings, better flood estimation to inform infrastructure and building design to be resilient to flooding.
Hydro-JULES will be applied and tested in several high-profile case studies in the UK for use in applications of particular stakeholder interest. In the first instance, attention will be paid to the necessary science developments required to enhance hydrological outlooks for the UK. Key links already in place with Defra / EA, the Flood Forecasting Centre and the Met Office's UK Environmental Prediction Programme will be maintained and extended. The stakeholder requirements for these applications will be sought at an early stage in the project. Applications of the coupled modelling system in overseas locations will be supported, where possible, in collaboration with additional funding streams, so that the UK research and academic community can be enabled to offer the greatest possible contribution to overseas development.
We will develop a protocol and demonstrator product to assimilate COSMOS-UK, satellite soil moisture data and river flow data. This work will result in a first-generation near-real-time UK soil moisture data product through blending of model output data, observed data (COSMOS-UK) and satellite data. This novel dataset will provide information on soil moisture drought for agricultural and ecological applications and will offer data on antecedent soil saturation for flood forecasters prior to extreme rainfall. Moreover, the new dataset will enable a range of scientific studies into soil moisture dry-down processes and land-atmosphere feedbacks and coupling, to improve model process descriptions and enhance skill in hydrological simulation. Further applications of more advanced data assimilation techniques, including the use of ensemble Kalman filters and 4-D variational methods for hydrological state updating and adjoint approaches to parameter estimation, will be explored in collaboration with project partners.
Benchmarking and evaluation protocols will be developed to support Earth system modelling applications, in collaboration with NCAS, the UKESM project and with modelling groups in the UK and overseas. The maintenance of clearly-defined model configurations will enable participation in world-leading model inter-comparison programmes including ISIMIP and WCRP GEWEX-coordinated experiments, in addition to the delivery of UK science components in preparation for participation in forthcoming CMIP7 and AR7 experiment cycles. This work package will also develop a procedure for the formal quantification of model uncertainty in large-scale hydrological predictions in order to understand the relative magnitude of uncertainties across model sub-components and to direct further research.

Title | Gridded estimates of daily and monthly areal rainfall for the United Kingdom (1890-2017) [CEH-GEAR] |
Description | 1 km gridded estimates of daily and monthly rainfall for Great-Britain and Northern Ireland (together with approximately 3000 km2 of catchment in the Republic of Ireland) from 1890 to 2017. The rainfall estimates are derived from the Met Office national database of observed precipitation. To derive the estimates, monthly and daily (when complete month available) precipitation totals from the UK rain gauge network are used. The natural neighbour interpolation methodology, including a normalisation step based on average annual rainfall, was used to generate the daily and monthly estimates. The estimated rainfall on a given day refers to the rainfall amount precipitated in 24 hours between 9am on that day until 9am on the following day. The CEH-GEAR dataset has been developed according to the guidance provided in BS 7843-4:2012. |

Title | Gridded estimates of hourly areal rainfall for Great Britain (1990-2014) [CEH-GEAR1hr] |
Description | The dataset contains 1km gridded estimates of hourly rainfall for Great-Britain for the period 1990-2014. The estimates are derived by applying the nearest neighbour interpolation method to a national database of hourly raingauge observations collated by Newcastle University and the Centre for Ecology & Hydrology (CEH). These interpolated hourly estimates were then used to temporally disaggregate the CEH-GEAR daily rainfall dataset. The estimated rainfall on a given hour refers to the rainfall amount accumulated in the previous hour. The dataset also contains data indicating the distance between the grid point and the closest recording raingauge used in its interpolation. When this distance is greater than 50km, or there is zero rainfall recorded in the closest gauge, the daily value is disaggregated using a design storm. The dataset therefore also contains a flag indicating if the design storm was used. These data are provided as an indicator of the quality of the estimates. |

Title | New North Atlantic Oscillation (NAO) based forecasting outputs operationalised in the Hydrological Outlook |
Description | A new set of outputs was added to the Hydrological Outlooks website from Dec 2020 - Feb 2021. This is new HydroJULES/UKSCAPE modelling outputs that were operationalised, namely a new high resolution North Atlantic Oscillation (NAO)-based seasonal forecast achieved through collaboration with UK Met Office. Through collaboration with the Met Office, we trialled running their GLOSEA-5 NAO forecasting outputs through a hydrological model (GR4J) already used in the Hydrological Outlook. We validated this through hindcasts, and after several years running as a pilot during wintertime, in Nov 2020 we operationalised this tool through the UK Hydrological Outlook. |
Type Of Technology | Webtool/Application |
Year Produced | 2020 |
Impact | The main impact was this methodology was operationalised and featured in the Hydrological Outlook UK, the UK's primary seasonal hydrological forecasting service. We developed a custom layout to show the outputs and these were featured each month through the winter, alongside the regular outputs. The NAO forecasts provided a different picture to the conventional forecasts, and this in turn led to the new forecasts having an impact on the operational multi-method summary forecast itself. This meant more confident forecast information could be provided to the user community for the upcoming winter, giving early warning of the potential for high river flows. |

Results and Impact | Hydro-JULES released two education packs (Silver and Gold) co-produced with the BSA, as part of the CREST Award scheme open to all schools, to introduce hydrological science to school children 14-18 yrs. We have produced a range of education tools to engage teenagers in hydrology and the work of Hydro-JULES. To arouse their curiosity and inspire them to consider a career in science, technology, engineering and maths (STEM), the Hydro-JULES team ditched the technical terms and instead focussed on themes that we felt would be most relevant to UK teenagers. The themes covered by these activities are varied, from researching the potential effects of a drought on businesses and industry to understanding the impacts of flooding on water quality and ecosystems in a local freshwater area. |
