Mike is the lead-PI on the POLLCURB project. As well as coordinating and managing the project activities, he is undertaking water quality model applications. Prior to the start of the project, Mike used the QUESTOR model of river water quality, in conjunction with models representing future climate and rainfall-runoff, to predict changes in River Thames water quality likely to occur during the 21st Century. In POLLCURB the intention is to refine these predictions by also considering the effect of projected urban growth, alongside other manifestations of future landuse change.
Led by Dr Mike Hutchins, the project POLLCURB is investigating how water pollution relates to change in urban areas, in particular that brought about population growth. The results of the project will provide valuable predictions of future water resources to help inform decision-making.
We will build detailed models to predict future impacts of urbanisation by using historic land-cover information in conjunction with long-term water flow and quality data. The models will also be simplified for scale-up to the whole Thames basin. Calculation of future impacts will be based on...
Most UK river basins are expected to be under increasing water stress as a consequence of future projected changes in flow regime as a result of climate drivers. To achieve sustainable utilisation of water resources, these pressures have to be balanced against the needs of a growing population and attendant pressures on land management.

Supported by a wide range of organisations, POLLCurb project is linked to a variety of activities by Changing Water Cycle research program, Earthwatch Institute global water initiative and ...
CEH scientists working on the POLLCURB project have teamed up with Earthwatch to train citizen scientists in carrying out water quality monitoring. The collaboration has come about via Earthwatch’s Freshwater Watch programme, which aims to study fresh water quality around the globe by engaging employees from participating organisations as citizen scientists.
Scientists at CEH and BGS have collaborated to produce a novel method for mapping long-term land use change in urban areas using historical topographic mapping produced by the Ordnance Survey. The mapping of Urban and Suburban land-use was subsequently used to derive mapping of impervious cover and was calibrated using mapping of impervious cover derived from aerial photography(See below the image, Miller and Grebby 2014).
James is a hydrological scientist at the CEH working primarily in the field of Urban Hydrology - researching the links between land use change and its impacts upon the local and regional hydrology. He is currently overseeing a large-scale monitoring programme across two urban areas – in Swindon and Bracknell – taking high-resolution measurements of stream and storm drain flows, soil moisture, water quality and rainfall. This data is being used to develop models of the local and regional impacts of urban land use change upon river flows and river water quality.

Water quality monitoring is important for us to understand the synergies and trade-offs between land use change and water quality as well as to implement water framework directive (WFD). The participation of citizen scientists is important for us to understand the wider issues of water quality in well-being and increase the resolution of sample collection as they help to increase the sampling resolution. CEH/POLL-CURB project is working with Earthwatch Institute/SHELL on providing training and education sessions for citizen scientists.
