Abstract. Effective flood risk management requires a realistic estimation of losses. However, available damage estimates are still characterized by significant levels uncertainty, questioning the capacity models to depict real damages. With joint effort eight international research groups, objective this study was compare, in blind-validation test, performances different for assessment direct residential sector at building level (i.e. microscale). The test consisted common case high...
Abstract MONERIS is a semi‐empirical, conceptual model, which has gained international acceptance as robust meso‐ to macro scale model for nutrient emissions. used calculate nitrogen (N) and phosphorus (P) emissions into surface waters, in‐stream retention, resulting loads, on river catchment scale. This paper provides the first (i) comprehensive overview of structure (both original elements new additions), (ii) depiction algorithms all pathways, retention in (iii) illustration monthly...
Rivers and floodplains are hotspots of biodiversity provide an exceptional number ecological functions. However, they negatively affected by human impact worldwide. The need for restoration is high, but its realization often hampered antagonistic interests. Replacing artificial riverbank protection with bioengineering techniques can be a first straightforward step to restore riparian ecosystems. still plays marginal role in river management. We aim introduce new arguments along riverbanks...
Floodplains have been degraded in Central Europe for centuries, resulting less dynamic and diverse ecosystems than the past. They provide essential ecosystem services like nutrient retention to improve overall water quality thus fulfill naturally what EU legislation demands, but this service is impaired by reduced connectivity patterns. Along second-longest river Europe, Danube, restoration measures carried out are planned near future Austrian Danube Floodplain National Park accordance with...
Abstract Mountainous catchments are usually not in focus of the modelling nutrient fluxes on catchment scale. Out 9 model approaches tested EU‐project EUROHARP only MONERIS claims to be capable nitrogen and phosphorus emissions a landscape with mountainous slope. Results derived present study indicate that 2.14 its current version is able reproduce measured loads rivers from alpine Austria size 70 400 km 2 . Despite this apparent limitation, delivers framework flexible enough offer...

The anthropogenic nitrogen turnover of Western societies is highly unbalanced. As a consequence, permanent supply via mineral fertiliser (produced with high energy inputs) and/or imported fodder are required and result in significant impacts emissions on the environment (air, water, soil). Key factors to an improved balance national scale nutrition habits population. According primary calculations shift from actual animal-based “healthier nutrition” (mainly characterised by 2/3 vegetable...
Floodplains are threatened ecosystems and not only ecologically meaningful but also important for humans by creating multiple benefits. Many underlying functions, like nutrient retention, carbon sequestration or water regulation, strongly depend on regular inundation. So far, these approached the basis of what called ‘active floodplains’. Active floodplains, defined as statistically inundated once every 100 years, represent less than 10% a floodplain’s original size. Still, should this...
This study analyses the computed nitrogen retention, distribution and extent of riparian floodplains three German rivers, as input data application retention model has not been carried out on landscape scale so far. The Software FLYS 2.1.3 was used for calculation floodplain depth at certain discharges. Thus a first empirical approach is suggested to quantify share load that enters (incoming load) variables depending discharge ratios. Measured loads have subsequently applied presented...
Floodplains are among the most valuable and threatened ecosystems. Worldwide, degradation restoration taking place at same time. In Germany, more than 90% of floodplains degraded, is carried out through several projects because benefits provide already known, though not yet quantified. Decision makers politicians still in need economic values, e.g. for cost-benefit analyses. Therefore, we sought to conduct a review ecosystem services (ES) German policy-relevant summary estimated ES valuation...
Abstract Floodplains provide a multitude of ecosystem functions and services with water purification being one them. For this study we modelled the retention total phosphorous (TP) in floodplains river Rhine Elbe, looking at sediment deposition as main process responsible for removing TP from rivers during inundation events. We applied two different approaches: proxy-based approach (PBA) one-dimensional model based (MBA). used both to calculate yearly compared it annual load rivers. Compared...
After a long history of floodplain degradation and substantial losses inundation areas over the last decades, rethinking management has taken place in Germany. Floodplains are now acknowledged as important for both biodiversity society. This transformation been significantly supported by nationwide research activities. A systematic assessment current is still lacking. We therefore developed scheme to assess through steps identification, analysis, implementation, evaluation. Reviewing data...
Fluvial floods in recent years (e.g., 2002 and 2013) have caused high financial losses Germany. Floodplains are under extensive use dikes disconnect two thirds of natural flood retention areas from rivers. Moreover, floodplains serve as hotspots biodiversity floodplain habitats well ecosystems categorized endangered. Additionally, the goal German National Strategy on Biodiversity increasing along rivers by at least 10% 2020 failed. In summary, urgent actions need to be taken reduce risk one...
<p>In the last centuries, rivers in Central Europe have severely suffered from hydro-morphological alterations and excessive nutrient inputs. Their adjacent floodplains ability to retain transported nutrients case of inundation, but are subject progressing decoupling main river stem. In Austrian Danube Floodplain National Park, restoration measures been carried out planned for near future increase lateral connectivity accordance with navigation...
