The use of optical brighteners has been previously established as a low cost way to diagnose missed connections. Use of UV light to identify the presence of these optical brighteners in watercourses in combination with a mobile device and mapping application and GIS data can help locate missed connections and remedy them. Using a simple UV filter attachment for a smart phone and citizen-science volunteers, indicator signals ...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.
In storms sewage can overflow into rivers or lakes. However, if there are blockages, miss connections or the water levels are too high then sewage can over flow all the time. This sewage becomes an environmental hazard. The idea is to use water proof RFID (Radio Freq Identifier) tags that are flushed down toilets/drains to help map route of sewage. If tags re-appear at exists into rivers or sea outlet when there are no ...more »
A web-based solution that combines spatial data relating to geology, soil, topography, wind, rain and insolation to suggest appropriate planting for your garden to any household in the UK.
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 »
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. Greenshield ...more »
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.
