The upfront capital costs associated with the installation and maintenance of water quality sensor systems are prohibitively high to a single customer. However we believe there are many customers who have need to access such data, from government (national & local) and associated agencies to water and insurance companies’, fisheries and surfers. Our intention is to become the primary provider of water quality information-as-a-service ...more »
Geovation Water Challenge
How can we better manage water use in Britain, sustainably?
This Challenge is now closed. The challenge ran from 1 December 2015 to 27 January 2016 (12noon). The winners of this challenge were:
Sustainable Catchments (Natural Flood Mitigation)
Fix our water
Geovation Camp was held at Ordnance Survey, Southampton 4-6 March.
The best ideas won support to research, develop and launch their product or service
The problems were grouped into 5 main themes:
Theme 1: Too little water
Theme 2: Too much water
Theme 3: Poor water quality
Theme 4: Ageing water infrastructure
Theme 5: Water use behaviour
The best ideas were invited into 12 month funded Geovation Programme to include financial, developer, and business support.
Create a national map of the areas where ‘natural’ flood mitigation measures (e.g. meandering, afforestation, drain blocking, restoring wetlands and washlands etc.) might be employed whilst minimising the impact on existing economic activities. The map would use topographic, land cover and soils data, coupled with agricultural and urban land use information, to rate the opportunity value. This could be extended by mapping ...more »
Planning guidance in the UK has introduced requirements for sustainable drainage to control surface water flowing from new developments but without wider coordinated catchment management these measure will impact on too few communities. As climate change increases, so will extreme precipitation events. Direct flood defences are becoming prohibitively expenses and more compensatory measures must be identified to prevent ...more »
High global temperatures and recent flooding suggest that severe flooding may become a regular event in parts of the United Kingdom. There is a need to develop robust hydrological / geo-physical models that could be used by researchers and the general public to examine, develop and evaluate localised solutions, including Natural flood Management and Flood Prevention Schemes. Comprehensive high-resolution bathymetric data ...more »
Gaining up-to-date, accurate and complete information *during* a flood is difficult as communications break down. Using off the shelf drones and sensors, create an autonomous system that can be deployed to survey, explore and/or monitor an area.
The media has encouraged a public perception that flood defences need to involve dredging, large-scale engineering and hard-defences. Adopting a catchment-based approach, identifying potential areas wherein soft defences could be effective, and valuing the flood mitigation benefits of engineered landscapes (in addition to their amenity value) would change public perception and encourage landowner participation.

40% of UK household have a water meter, and although meters aren't compulsory in most areas they are standard on new-builds, and may be fitted compulsorily in some circumstances (such as areas of water stress or when you move home - OFWAT). Reading the water meter is often difficult - mine is under water for 1/3 of the year but I useually manage to take a picture of it every week and now have 3 years of data. Similarly ...more »
There are many locations where roads and railways are carried across river valleys on solid embankments, with rivers and streams passing through culverts. My idea is to use GIS to identify where a simple gate structure could be inserted into the culvert and hold back flood water, flooding the upstream land and therefore attenuating the flood flow with online storage behind the embankment. Just flooding a small area to ...more »
The Sustainable Housing Digital Engagement Tool is an online GPS model facilitating tool that will facilitate a democratic debate on future housing location, allowing decisions to be made based on the provision of all relevant data required for a sustainable approach to housing location at the local level.
To create an interactive playbox which mixes layers of physical data with visual animation and feedback. The real-life sand in the box can be played with and the data is fed into the computer. The software processes parameters such as the height of the sand and hand motions made by the users; and then projects back onto the sand visual geographical information, including elevation, contour lines, rainfall and water flow ...more »
Extensive flooding has hit the headlines recently, affecting area that were previously seen as safe. The likely cause is the continued rise in global temperatures, resulting in the possibility of further extreme weather patterns. In the past the solution has been to use risk analysis to predict potential floods and provide flood defenses in vulnerable areas based on probability of severity. However with the continued ...more »
This idea is about helping people take steps to design their own Natural Flood Management Scheme. After some very simple training they would use an App to record what can be done where. These can then be discussed with the farmer and landowner to agree a package of works to Slow the Flow. This way local people take ownership, farmers and landowners are working with local people and things can move very quickly.
Many of the issues relating to poor quality water need more data - both in quantity, quality and spatial distribution. Mass-produced sensors will be deployed in drains and sewers, on groynes and sea-walls, in lakes and ponds, and in rivers where they will sit on the river bed (float/move up/down as required). They will sense water quality, turbidity, acidity et al. and transmit data continuously/periodically. Data ...more »
A low-cost way to determine channel characteristics of watercourses, even if subterranean (urban or natural)

Maybe you could screen eels using the same principal that Dyson vacuum cleaners use to separate fine dust, namely a low pressure region in a vortex?
