Flood risk assessment is an essential part of flood risk management. As part of the new EU flood directive it is becoming increasingly more popular in European flood policy. Particularly cities with a high concentration of people and goods are vulnerable to floods. This paper introduces the adaptation of a novel method of multicriteria flood risk assessment, that was recently developed for the more rural Mulde river basin, to a city. The study site is Leipzig, Germany. The "urban" approach includes a specific urban-type set of economic, social and ecological flood risk criteria, which focus on urban issues: population and vulnerable groups, differentiated residential land use classes, areas with social and health care but also ecological indicators such as recreational urban green spaces. These criteria are integrated using a "multicriteria decision rule" based on an additive weighting procedure which is implemented into the software tool FloodCalc urban . Based on different weighting sets we provide evidence of where the most flood-prone areas are located in a city. Furthermore, we can show that with an increasing inundation extent it is both the social and the economic risks that strongly increase.

Abstract. Flood events cause significant damage not only on the surface but also underground. Infiltration of surface water into soil, flooding through the urban sewer system and, in consequence, rising groundwater are the main causes of subsurface damage. The modelling of flooding events is an important part of flood risk assessment. The processes of subsurface discharge of infiltrated water necessitate coupled modelling tools of both, surface and subsurface water fluxes. Therefore, codes for surface flooding, for discharge in the sewerage system and for groundwater flow were coupled with each other. A coupling software was used to amalgamate the individual programs in terms of mapping between the different model geometries, time synchronization and data exchange. The coupling of the models was realized on two scales in the Saxon capital of Dresden (Germany). As a result of the coupled modelling it could be shown that surface flooding dominates processes of any flood event. Compared to flood simulations without coupled modelling no substantial changes of the surface inundation area could be determined. Regarding sewerage, the comparison between the influx of groundwater into sewerage and the loading due to infiltration by flood water showed infiltration of surface flood water to be the main reason for sewerage overloading. Concurrent rainfalls can intensify the problem. The infiltration of the sewerage system by rising groundwater contributes only marginally to the loading of the sewerage and the distribution of water by sewerage has only local impacts on groundwater rise. However, the localization of risk areas due to rising groundwater requires the consideration of all components of the subsurface water fluxes. The coupled modelling has shown that high groundwater levels are the result of a multi-causal process that occurs before and during the flood event.

An important driving force behind urban expansion is the growth of the urban population. But for Europe, this is not a sufficient explanation. The major trend is that European cities have become much less compact. Since the mid-1950s European cities have expanded on average by 78%, whereas the population has grown by only 33%. In the PLUREL project - an integrated project within the EU's 6th Research Framework Programme - more than 100 researchers from 15 countries analysed the impacts of urban land consumption at a pan-European level and, through six European and one Chinese case studies, identified how land use conflicts and the pressure towards peri-urban areas can be strategically managed in different development and regulatory contexts. To summarise, the following strategies were identified as important steps towards more sustainable urban-rural futures: (i) better coordination of transport, land use and open space planning; (ii) urban containment and densification – development of a green compact city; (iii) preservation of blue and green infrastructure; and (iv) preservation of agricultural land and the promotion of local production. The need also remains to strengthen governance at the regional level while at the pan-European level there is clearly a need for more policy attention to be given to urban-rural linkages.

The legal basis for the use of laboratory diagnostics has been fundamentally changed by the European In-vitro Diagnostics Regulation (EU) 2017/746 ("IVDR"). Until this set of regulations comes into full force in May 2022, the entire laboratory diagnostics industry in Germany will only have a short transitional phase to adapt its processes. This affects laboratories that partly or predominantly use in-house tests; here, substantial new requirements must be met. Since the implementation of IVDR is committed to improving patient safety, a prolongation of the transition period by politicians - despite the COVID-19 crisis - is not likely. On the one hand, laboratories need to prepare for increased regulatory supervision of in-house tests. On the other hand, with respect to infringements of competition law, there is a risk that individual diagnostic manufacturers will take action against laboratories using in-house tests, even though a comparable commercial test is available. One of the problematic consequences for patient care can also be that tests covering rare diseases, so called "niche tests", that were previously commercially available but have low sales, could be withdrawn from the market by manufacturers due to the considerably increasing documentation requirements. Even though the adaptation of national regulations and implementation rules is not yet finished, every medical laboratory is strongly advised to already start dealing with the innovations brought by the IVDR. ; Die rechtlichen Grundlagen für die Verwendung von Labordiagnostika haben sich durch die Europäische Verordnung über In-vitro -Diagnostika (EU) 2017/746 ("IVDR") fundamental geändert. Bis zum vollen Inkrafttreten dieses Regelwerkes im Mai 2022 bleibt der gesamten Labordiagnostik in Deutschland nur noch eine kurze Übergangsphase für die Anpassung ihrer Prozesse. Betroffen sind hiervon insbesondere Labore, die zum Teil oder überwiegend Tests aus Eigenherstellung anwenden; hier müssen wesentliche neue Anforderungen eingehalten werden. Da die ...
