Making cradle-to-cradle work : first steps for Dutch infrastructure challenges
In this paper we show how the C2C concept (cradle to cradle) can help Rijkswaterstaat to achieve it's sustainable ambitions with regard to infrastructure projects. We describe the process and the practical applications the C2C concept has for the redesign of a lock and construction of a motorway.
Signal test for acoustic fibre optics for leakage detection of water bottoms
The goal of this project is to analyse the results of the two large laboratory tests in order to assess whether distributed fibre optic sensing can detect the presence or absence of a clay layer in a water bottom. It is about a ‘signal test’ which must show that variations in lithology of the water bottom have an effect in the measured signal. The experiments for which the distributed fibre optic measurements have been performed consisted of experiments at a scale of 18 m x 5.5 m surface area and 2.5 m depth and for which fibre optics cable for acoustic and temperature measurements has been placed in a send bed of 80 cm thickness and covered with a clay layer of 10 cm. Three situations have been analysed.
ACER : developing Adaptive Capacity to Extreme events in the Rhine basin
The overall aim of ACER is to investigate the impact of climate change and to explore adaptation strategies for the Rhine basin under climate change, for both basin wide as well as regional water managers. The ACER project follows a so-called scenario analysis whereby solution trajectories are analyzed and compared, under the assumption of various long-term climate change and socio-economic scenarios. Adaptation can significantly reduce impacts of climate change and is seen as an important part of societal response to global climate change. Planned adaptation implies decisions and measures within society that help to anticipate to climate related risks.
Storm surge modelling in the South China Sea
Sea level anomalies (SLA) due to different phenomena have been observed in various parts of the South China Sea (SCS). Excluding tsunamis, the largest anomalies are classified as storm surges. Storm surges in the most southwestern part of the SCS are associated with a strong persistent wind blowing along the longest axis of the sea, roughly passing through Taiwan and Singapore.

Cities on the grow : pathways to supporting the sustainable growth of urban food enterprises in London, Reading and Almere
Cities on the Grow is a cross-disciplinary project that has been funded by Climate-KIC, an initiative of the European Institute of Innovation and Technology. It seeks to support the sustainable growth of urban food enterprises toward the implementation of more commercially viable business practices. It also seeks to secure the social and climate benefits of these enterprises while enhancing their role in city-regional food economies. This pilot study was aimed at investigating the local food systems of London (UK), Reading (UK) and Almere (NL) with the intention of establishing how urban food enterprises operating in these locations can be supported to realise their goals of localised, commercially viable, socio-ecologically just food systems.
Combining water and energy supply
This study explores the feasibility of a distribution and storage system that supplies both heat and cold based on local sources and drinking water to buildings. By combining thermal energy and drinking water supply in one network would save on underground distribution network. This study was conducted as part of the Dutch research programme 'Knowledge for Climate'.A conceptual framework is provided to determine 1) heat demand of an urban area, 2) heat yield of the urban water system and 3) heat storage capacity of the urban aquifer system. This framework is applied to a mainly residential suburb of Amsterdam. Results show that 25% of the demand can be provided by the urban water system and cycle in a time period when it can be used directly. A further 75% of heat is available in periods when there is no demand. Aquifer thermal energy storage can provide enough heat storage to provide a solution for the temporal mismatch between energy availability and demand.The overall energy performance of using the urban water cycle for heat supply and storage was compared to the primary energy consumption of a traditional system. The Epr of this system compared to a traditional system shows a 7% reduction. Key factors limiting the energy savings are the seasonal performance factor and the conversion factor of primary energy to electrical energy.The urban water system can provide an effective source of heat for urban areas. However, a more detailed design and more research are on both the thermal and economic efficiency. Delivering both drinking water and thermal energy using the same network does not seem feasible. The water quality in the combined distribution network can not be guaranteed to meet consumption standards. Point source purification can be used as a solution, but the higher cost for providing drinking water and the slightly increased health risk are expected to outweigh the advantage of saving on one distribution system.
Holistic management of brownfield regeneration (HOMBRE) : early indicators for brownfield origination
One of the first objectives of HOMBRE is to get a better understanding of why, how, where and when brownfields are formed, in order to avoid future BFs as much as possible. To this end, ‘early indicators’ are identified, that can aid in anticipating brownfield formation and related problems in an early stage. Then, through managed intervention, this could be prevented from happening. Thus, the goal of the early indicators is to have a signalling function towards persons or organisations responsible for land management. The management level specifically considered is that of the municipality. In total, around 40 early indicators have been identified through literature review, that are viewed to be generically usable. They have been grouped into clusters within the categories of economic, social and environmental indicators. Municipal land managers are envisaged to select from the list of suggested indicators the ones that are most relevant and convenient in their situation.
Geological survey of the Hondsrug megaflute, Drenthe, the Netherlands
Ice streams always reflects an unbalance between accumulation and ablation in ice sheets and along ice sheet margins they are highly variable and dynamic in space and time. Present-day and Last Glacial examples of ice streams demonstrate a behaviour of switching on and off; acceleration and deceleration, migration and change of direction. The situation at the ice margin provides a main control on the mass (in)balance of the ice stream, for example where melting or calving occurs in ice lakes, seas and oceans. The knowledge on controlling factors and process dynamics of present day ice streams has much grown. For paleo-ice-streams, however less studies truly assess process-relations, especially in NW Europe. We have focussed on the Hondsrug – Ice Stream of Saalian age (Drenthe Substage, within MIS 6) in NE Netherlands and NW Germany, glaciated in the penultimate glacial, but not in the last glacial. The best expression is a 60 km long megaflute complex landform, known as ‘Hondsrug’. Because of its unique genesis and preservation, the Province of Drenthe has nominated the Hondsrug to be a UNESCO - GEOPARK. Results are discussed and related to Winsborrow et al. (2010) hierarchy of controls of ice streams. We have strong reasons that ice streams of the terrestrial ice margins of the former Scandinavian ice sheets of the North Sea, German, Polish and Baltic area are controlled in a different way than e.g. Antarctic actual- and North American palaeo-examples. The ice-streams appear regional initial deglaciation phenomena, affected by substrate and ice-margin control primarily, rather than larger scale expanding ice-cap phenomena. This conclusion opens new approach in understanding the scales and dynamics of ice streaming at the tipping point of maximum glaciation to initial deglaciation, and input for further research between the North Sea and the Baltic.
