Ten years profile soil moisture and temperature measurements in Twente
No full textThe Twente region in the east of the Netherlands hold a network that monitors since 2009 profile soil moisture and temperature at twenty locations mostly in the rural environment. In addition, intensive measurement campaigns have been performed in 2009, 2015, 2016, and 2017 at number of measurement locations as a part of MSc and PhD research. The development of the network infrastructure has been supported through various EU and NWO-funded projects, and forthcoming data has been successfully used for the validation of satellite derived surface soil moisture products.
The early development of the network has been described in Dente et al. (2011), but over the years the design of the network has altered considerably with the most recent updates documented in Van der Velde et al. (in review).
In 2019, the Twente network has been operational for more than a decade and with this deposit we would like to make this data freely and well documented available for use by the science and professional communities. An accompanying data paper is under development, which provide additional background information.

Amsterdam Oost: Parallellisme. Route-ontwikkeling als stedelijke vernieuwingsstrategie
No full textHet gepresenteerde werk is de uitkomst van een duaal-afstudeerproject, waarmee zowel een Master Architectuur als Stedenbouw is behaald. Het onderzoek is uitgevoerd binnen de studio ‘vernieuwing van de stadsvernieuwing’, waarin onderzocht werd hoe wijkgerichte en stedelijke voorzieningen ingezet kunnen worden als instrument voor stedelijke vernieuwing. Daarmee bood de studio de mogelijkheid om binnen een academische omgeving voorstellen te ontwikkellen die als voorbeeld kunnen dienen voor een nieuwe aanpak van stedelijke vernieuwing. Het onderzoek richt zich op een studiegebied in Amsterdam Oost. Het vertrekt vanuit de problematiek van ‘probleemwijk’ Transvaal en tracht via een ontwikkelde stedelijke vernieuwingsstrategie buurt, wijk en stad met elkaar te verweven. Daarbij is bestudeerd hoe route-ontwikkeling kan worden ingezet als stedenbouwkundige strategie, aan de hand van kleinschalige afgebakende interventies. Voor de verschillende interventies zijn tevens ontwerpen gemaakt die in dit rapport worden gepresenteerd.Vernieuwing van de stadsvernieuwingArchitectureArchitectur
Topos, topology or topography
No full textThe manipulation of topography is an important part of landscape architcture practice, but is generally thought of as a technical endeavour since the geometry of landform is difficult to represent. Since representation is complicit with design generation, the ability to design in an intuitive fashion is limited to how easily it can be represented. In order to change the way that topography is designed by landscape architects, the conventions of topographic representation must be reconsidered.\ud
\ud
In this chapter the author discusses his masters by design research that critically considered the conventions of representing topography and the sort of design outcomes that result from tehse. Through deisgn studies new methods are develoepd to enrich the design of landscapes with topography, and new forms fo space and experience that result are considered

Labour-market in a border-area; searching for jobs and the influence of borders
Get PDFAt the moment borders, border-related problems, and the process of tearing down borders are very much in the centre of interest. Especially in Europe a lot of scientific work is done with regard to borders of countries, to determine their role in the ongoing integration process. In this respect border-regions are considered to be able to play a catalytic role. The borderland economies on both sides of a national border in this view have to be changed into one transborder economy. Initiatives to encourage cross-border integration however are not always successful. To our opinion, one of the main reasons lies in the fact that the border has many faces. The effect of a border differs, depending on the type of interaction (e.g. economic, social-cultural or institutional) and the nature of the region it defines. This paper tries to formulate a conceptual framework, within which the different properties of borders and border-regions are taken into account. Next this model is applied to the regional labour-market in the Nijmegen-Arnhem border-area in the eastern part of the Netherlands. The most important questions to be answered are: - Are there effects stemming from the fact the regional labour-market in the Arnhem-Nijmegen is part of a (peripheral) borderland economy? - What are the effects of the border with regard to the interaction of the region Arnhem-Nijmegen with the neighbouring region in Germany? - Is a part of the "natural" labour-market cut off by the national border, or put in other words, what would happen if the Dutch-German border would disappear completely?

Catchment-scale non-linear groundwater-surface water interactions in densely drained lowland catchments
No full textFreely discharging lowland catchments are characterized by a strongly seasonal contracting and expanding system of discharging streams and ditches. Due to this rapidly changing active channel network, discharge and solute transport cannot be modeled by a single characteristic travel path, travel time distribution, unit hydrograph, or linear reservoir. We propose a systematic spatial averaging approach to derive catchment-scale storage and discharge from point-scale water balances. The effects of spatial heterogeneity in soil properties, vegetation, and drainage network are lumped and described by a relation between groundwater storage and the spatial probability distribution of groundwater depths with measurable parameters. The model describes how, in lowland catchments, the catchment-scale flux from groundwater to surface water via various flow routes is affected by a changing active channel network, the unsaturated zone and surface ponding. We used observations of groundwater levels and catchment discharge of a 6.6 km<sup>2</sup> Dutch watershed in combination with a high-resolution spatially distributed hydrological model to test the model approach. Good results were obtained when modeling hourly discharges for a period of eight years. The validity of the underlying assumptions still needs to be tested under different conditions and for catchments of various sizes. Nevertheless, at this stage the model can already improve monitoring efficiency of groundwater-surface water interactions
