Abstract

Urban water systems are under increasing pressure due to the impact of climate change, population growth and urbanisation. In order to make our urban water systems more adaptable to these challenges new water management strategies must be developed. During the last 20 years many new decentralised technologies have emerged and their integration with existing centralised technologies, in particular, creates complex interactions. To deepen our understanding of these interactions at the city scale and to identify possible transition strategies the development of a potential strategic planning tool is thus proposed. This paper focuses on the evolution of the urban environment and water system, in space and time, in the tool. The dynamics of the model is shown for alpine cities. Numerous test cases are stochastically generated by means of the virtual infrastructure benchmarking approach and evolved over time. Different scenarios for the development of the urban environment and water system are statistically evaluated. An increase of rainfall intensities of more than 10% was identified as critical for the performance of the combined sewer systems investigated. By using DAnCE4Water such critical points in the time line of system performance can be identified.

DynaMind Version 0.5

DynaMind 0.5 is now available for Download. The changes are mostly in the backend of DynaMind, code cleaning and initial work to move the data structure on the DB. So no new features yet but increased stability and usability.

Export Results to the Web

The DynaMind-Analysis toolbox provides a simple module to export your simulation results. The TileMill exports vector and raster data into tiles that can later be shown within a html viewer. For every view a user defined style can be defined. The tile rendering itself is done with mapnik.

for the viewer I used leafletjs.

The module is not very user friendly yet but I’ll add a GUI in the next couple of weeks.
