This paper presents a risk-based method to quantify climate change effects on road infrastructure, as a support for decision-making on interventions. This can be implemented in climate adaptation plans as an element of asset management. The method is illustrated by a specific case in which traffic on a road network is disrupted by the flooding...

When dredging in sensitive environments, efforts have to be made to limit the free dispersal of suspended fine sediment from the dredging spill. Especially the use of hanging silt curtains as an environmental mitigation measure is widespread. Despite frequent application, their ability to reduce turbidity levels through vertical diversion of...

One of the potential environmental issues associated with dredging in the marine environment is the increase of suspended sediment concentrations (SSC) by generation and dispersion of sediment plumes. This can be mitigated by source control or by the installation of containment barriers like silt screens. This article focusses on hanging silt...

The heterogeneity of the contemporary metropolitan landscape has led to a multiplicity of intermediate spaces, in between and within the different tissues of the metropolitan landscape. These interstices can provide favourable conditions to be transformed into gardens. What design instruments can be discovered for these gardens to address the...

This paper reports on the corrosion performance of composite zinc layers (~ 8µm) on a steel substrate, considering the influence of nano-aggregates and Cr(III) conversion layers, compared to control (only Zn layers) conditions. The main factors, influencing the corrosion performance of Zn in this study are: a) the effect of two concentrations of...

Bij het werken aan historische tuinen heeft de landschapsarchitect niet alleen te maken met de vele tijdslagen die een ontwerp hebben veranderd in wat het nu is – ook andere disciplines spreken zich uit over de waarde en waardevolle elementen die er in voorkomen. Dat leidt tot soms starre voorschriften die de objecten geen goed doen. Een...

The term genius loci—“the prevailing character or atmosphere of a place,” as the Oxford English Dictionary defines it—has long been used to interpret landscape characteristics. Lately, however, it is being used, and abused, as a justification in just about any discourse. For spatial, aesthetic, and ecological discussions and social, cultural,...

This study presents the results on the investigation of the corrosion behavior of carbon steel in model alkaline medium in the presence of very low concentration of polymeric nanoaggregates [0.0024 wt % polyethylene oxide (PEO)113-b-PS70 micelles]. The steel electrodes were investigated in chloride free and chloride-containing cement extracts....

This work reports on monitoring chloride-induced corrosion in reinforced mortar specimens, with and without addition of polymeric nano-aggregates in the mortar mixture. The investigation is a novel approach to control steel corrosion in reinforced concrete, hereby reporting the preliminary results, related to one of the main objectives: studying...

This work presents the preliminary tests on the performance of cathodic prevention (CPre) in reinforced mortar, subjected to aggressive (10% NaCl environment). Cathodic prevention is an electrochemical technique for minimizing, actually "preventing" any eventual corrosion of the steel bars in reinforced concrete. Therefore, the main objective of...

This work reports on the electrochemical performance of low-carbon steel electrodes in model alkaline solutions in the presence of 4.9.10-4 g/l hybrid aggregates i.e. cement extract, containing PDADMAC (poly (diallyl, dimethyl ammonium chloride) / PAA (Poly (acrylic acid)/ PDADMAC over a CaO core. The main objective was to determine if the...

This study presents the results from a preliminary investigation on the corrosion behavior of low carbon steel in cement extract (CE) in the presence of very low concentration polymeric nanoaggregates (PEO113-b-PS70 micelles). The steel electrodes were investigated in Cl--containing CE as corrosion medium, compared to chloride-free CE as a...

The evacuation clearance time is one of the key indicators in an evacuation plan and is determined by the expected behavior of the endangered residents and roadway network characteristics. The city of Almere has developed an evacuation plan in case of the emergency of a flooding, but assumes a normal driving behavior of the evacuees. In this...
