“…Many studies have attempted to quantify biostabilisation in a variety of environments (Paterson, 1989;Dade et al, 1990;Amos et al, 1998;Tolhurst et al, 1999Tolhurst et al, , 2003Friend et al, 2003a;Droppo et al, 2007;Righetti and Lucarelli, 2007;Vignaga et al, 2012;Graba et al, 2013;Thom et al, 2015). These studies generally show a positive correlation between EPS content and sediment stability measured as the threshold for erosion, although variations in space and time (Friend et al, 2003b;Thom et al, 2015) and between cohesive and noncohesive sandy environments are large.…”

“…Predicting the potential impacts of climate change on aquatic environments and applying bioengineering adaptation strategies like "building with nature" for coastal defence (de Vriend et al, 2015) or flood resilience (Temmerman et al, 2013) requires an understanding of (i) the response of micro-organisms to changes in climate-induced hydrodynamic forcing and (ii) the role of micro-organisms in water and sediment transfer systems. To date, quantification of biostabilisation effects in space and time remains scarce however.…”

Quantifying biostabilisation effects of biofilm-secreted and extracted extracellular polymeric substances (EPSs) on sandy substrate

Abstract. Microbial assemblages ("biofilms") preferentially develop at water-sediment interfaces and are known to have a considerable influence on sediment stability and erodibility. There is potential for significant impacts on sediment transport and morphodynamics, and hence on the longer-term evolution of coastal and fluvial environments. However, the biostabilisation effects remain poorly understood and quantified due to the inherent complexity of biofilms and the large spatial and temporal (i.e. seasonality) variations involved. Here, we use controlled laboratory tests to systematically quantify the effects of natural biofilm colonisation as well as extracted extracellular polymeric substances (EPSs) on sediment stability. Extracted EPSs may be useful to simulate biofilm-mediated biostabilisation and potentially provide a method of speeding up timescales of physical modelling experiments investigating biostabilisation effects. We find a mean biostabilisation effect due to natural biofilm colonisation and development of almost 4 times that of the uncolonised sand. The presented cumulative probability distribution of measured critical threshold for erosion of colonised sand reflects the large spatial and temporal variations generally seen in natural biostabilised environments. For identical sand, engineered sediment stability from the addition of extracted EPSs compares well across the measured range of the critical threshold for erosion and behaves in a linear and predictable fashion. Yet, the effectiveness of extracted EPSs to stabilise sediment is sensitive to the preparation procedure, time after application and environmental conditions such as salinity, pH and temperature. These findings are expected to improve biophysical experimental models in fluvial and coastal environments and provide much-needed quantification of biostabilisation to improve predictions of sediment dynamics in aquatic ecosystems.

“…The combination of ecological models, existing geo-datasets and 3D visualizations is becoming more relevant with the so-called 'Building with Nature' solutions. Building with Nature is an initiative that focuses on the development of nature combined with other utilities [3]. For example, instead of creating a strong dike to protect the land against water, ecological process are utilized in the target area to develop natural dunes that can provide protection.…”

Interactive 3D visualization of natural environments can help ecologists, policy makers and the broad public in general to better understand, promote and protect both existing and developing environments. The creation and exploration of virtual worlds can be very helpful for this purpose. However, current techniques are not able to generate sound complex natural environments from ecological data for the use of interactive webbased visualizations. In this thesis, we approach the challenge of developing and interactively visualizing in real time ecologically accurate and visually convincing models of complex natural environments over the web. For this, we propose a framework that (i) is able to combine landscape maps and ecological statistical data, translating them to an ecologically sound plant distribution, and (ii) creates a detailed 3D representation of the natural environment and provides for its fully interactive visualization in real-time over the web. The main contributions of this research are a procedural method to generate complete and sound natural environments and a web-based renderer that is able to real-time visualize complex natural environments with their high density and variability of individual organisms. The vegetation model combines and improves techniques from procedural ecosystem generation and neutral landscape modeling. It is able to generate diverse ecological sound plant distribution directly from landscape maps with statistics about coverage and patchiness of plant species. The visualization model uses several existing level-of-detail and illumination techniques to achieve interactive frame rates and improve realism. Validation of the results with ecology experts led us to conclude that our framework provides convincing interactive visualizations of large virtual natural environments.iii
