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.

Best practice guidelines for the integrated planning and design of economically sound and environmentally friendly roads in the Mekong floodplains of Cambodia and Viet Nam : synthesis report
For a number of reasons road development in a floodplain, like the still quite natural Mekong floodplain, requires a different approach to planning and technical design, compared to road development in areas that are not regularly) inundated. On the one hand, floods can severely damage infrastructure including roads, whilst on the other hand, roads and associated infrastructure fragment the floodplains and interrupt the natural flow of water, sediments, nutrients and aquatic life. The underlying question addressed by the ‘Roads and Floods’ project, is how to develop roads in a sensitive ecosystem like the floodplain of the Mekong in a sustainable manner that minimizes the impact on the benefits of the annual inundations and at the same time reduces damage to roads. The main findings of the project are presented in this synthesis report.

Holistic management of brownfield regeneration (HOMBRE) : decision support system on soft reuses
Often brownfields reuse is considered in the context of hard reuses such as for housing, business parks or infrastructure. Soft end uses, such as green space or biomass production, can tend to be overlooked. However, soft end uses can provide services which enhance regeneration, both in their own right and when integrated with hard uses such as for buildings. HOMBRE (Holistic Management of Brownfield Regeneration) was a major EU FP7 project which concluded in November 2014. One of its outputs is a simple design aid to help developers and others involved in brownfields to identify what services they can get from soft reuse interventions for their site, how these interact and what the initial default design considerations might be. This report is the presentation and explanation on how to use this design aid to better assess and design soft reuse interventions and services within brownfield regeneration processes. We explain and show how we connect services with interventions and the other way around. How to implement this in the regeneration process in order to increase the overall project success and sustainability.
The 3D Dutch Continental Shelf Model - Flexible Mesh (3D DCSMFM) : setup and validation
This report deals with the setup and validation of a three-dimensional hydrodynamic model (3D DCSM-FM) of the Northwest European Shelf, including the North Sea and adjacent shallow seas and estuaries such as the Wadden Sea and the Eastern and Western Scheidt. The model is developed in D-HYDRO Flexible Mesh and is based on the horizontal schematization of the 2D DCSM-FM model. Unlike this 2D model, 3D DCSM-FM includes temperature and salinity as state parameters. The validation is performed for three configurations of the model, which differ from each other with respect to horizontal resolution, model bathymetry and bottom roughness.
Understanding the present-day morphodynamics of Ameland inlet, part 2
The Kustgenese 2.0 program has resulted in unique high-resolution bed surveys of Ameland inlet. These measurements allow us to (1) investigate, analyse and better understand the morphodynamic changes on its ebb-tidal delta, and (2) to investigate the half-yearly changes in sediment budget. A time series of near yearly ebb-tidal delta bathymetries over the past decade, displays how initial small-scale perturbations in the central part of the ebb-tidal delta (the ebb-chute and shield systems) develop, grow, migrate and start to dominate the developments of the entire ebb-tidal delta. The realisation that small-scale perturbations result in ebb-tidal delta scale relocation of channels and shoals has important implications for the future morphadynamie modelling of the area. These morphodynamic models will have to contain sufficient resolution and detailed processes to capture such distortions. The high-resolution multi-beam data obtained in Ameland inlet provides valuable information on the prevailing sediment transport directions. Such knowledge is essential for the future validation of our process-based sediment transport models. Based on these surveys, we are able to construct sediment transport patterns for the proximal part of the ebb-tidal delta; Borndiep is primarily ebb-dominant and Westgat flood-dominant. These transport directions correspond to the sediment transport patterns derived from the morphodynamic changes. Correspondences in repeat surveys on the ebb-tidal delta confirm that (1) bedform asymmetry is an indicator for bedform migration, and (2) coherent, consistent, bedform fields occur through the various surveys.
