Release and load of urban stormwater can affect biodiversity in recipients in both a short and long term perspective. For shallow lakes where natural shifts can occur between clear water and turbid water states due to asymmetric competition between different groups of algae, the role of urban stormwater load over the long term is of […]
Fog collection by man-made collectors has been proved to be a non-conventional source of water. Applications exist in many countries where conventional methods cannot provide an adequate supply of water. Alternative ways of gathering water in arid and semi-arid environments have always meant a challenge for dwellers of those areas. Recently, fog-water harvest is becoming […]

Sustainable management of stormwater in urban environments can result in economic gains for the society. However, there are only a few studies made on the evaluation of social and environmental impacts of a sustainable urban drainage system. In the present work, a subjective method has been developed for evaluating the sustainability of elements from a […]
