Despite continuous investment and various efforts to control pollution, urban water environments are worsening in large parts of the developing world. In order to reveal potential constraints and limitations of current practices of urban water management and to stimulate proactive intervention, we conducted a material flow analysis of the urban water system in Kunming City. The results demonstr...

This paper reports on the ongoing work and research involved in the development of a socio-technical model of urban water systems. Socio-technical, means the model is not so much concerned with the technical or biophysical aspects of urban water systems, but rather with the social and institutional implications of the urban water infrastructure and vice versa. A socio-technical model, in the vi...

Three different drainage systems were built in a roadside car park located on the outskirts of Oviedo (Spain): two sustainable urban drainage systems (SUDS), a swale and a filter drain; and one conventional drainage system, a concrete ditch, which is representative of the most frequently used roadside drainage system in Spain. The concentrations of pollutants were analyzed in the outflow of all...

Comprehensive master drainage plans are not a new concept in engineering. Engineers for decades have been planning drainage projects encompassing many of the facts of what is called comprehensive plan­ ning. The difference between the past and the present is the availability of high speed computers and that now these facets have to be included and documented for public and private acceptance an...

Correct prediction of flood extents in urban catchments has become a challenging issue. The traditional urban drainage models that consider only the sewerage-network are able to simulate the drainage system correctly until there is no overflow from the network inlet or manhole. When such overflows exist due to insufficient drainage capacity of downstream pipes or channels, it becomes difficult ...

This work introduces RADIUS, a framework for anomaly detection in sewer pipes using stereovision. The employs three-dimensional geometry reconstruction from stereo vision, followed by statistical modeling of the with generic pipe model. is designed to be compatible existing workflows defect detection, as well provide opportunities machine learning implementations future. We test on 48 image set...
