Abstract This study evaluated the effects of vegetation and internal water storage (IWS) on evapotranspiration (ET), hydrologic performance, and water quality in bioretention mesocosms. Twelve mesocosms were configured as planted/free-drainage (PF), planted/IWS (PI), unplanted/free-drainage (UF), and …

Conventional centralised sewerage systems are increasingly challenged by climate change, population growth and sustainability goals. Decentralised wastewater treatment systems (DWTS) offer an alternative by reducing hydraulic loads, enabling local reuse and supporting resource recovery. This study analyses …

Cape Town faces a complex and interlinked set of climate-related challenges, including recurring droughts, flooding, intensifying heat stress and biodiversity loss. These impacts are further amplified by rapid urbanization, pollution (often due to poor infrastructure and service delivery), ageing water …

Permeable pavements are implemented at more than thousand locations enabling rainfall infiltration and evapotranspiration of stormwater in The Netherlands. However, the efficiency has not been extensively tested. Therefore, research is conducted using a full-scale infiltration test (FSIT) method to measure …

Introduction of MOOC (and CDRI report): train the Trainers in Delhi, 2 day workshop on nature-based solutions

In 2024 the Low Impact Development Devices (LID) open-source international database ClimateScan consist of over 14.000 climate adaption related projects uploaded in the period of 2014–2024. For cities with over 500 projects, this offers an opportunity to construct a LID-DNA of the city. LID-DNA presents …

Greater New Orleans is surrounded by wetlands, the Mississippi River and two lakes. Excess rain can only be drained off with pumping systems or by evaporation due to the bowl-like shape of a large part of the city. As part of the solution to make New Orleans climate adaptive, green infrastructure has …

Infiltrating pavements are potentially effective climate adaptation measures to counteract arising challenges related to flooding and drought in urban areas. However, they are susceptible to clogging causing premature degradation. As part of the Dutch Delta Plan, Dutch municipalities were encouraged …

International Conference “Groundwater, key to the Sustainable Development Goals”. Paris, May 18-20th, 2022ClimateCafé is a multi-, trans-, interdisciplinary and international event of several days in which young professionals, stakeholders and scientist come together to collect data and design (potential) …

Swales are widely used Sustainable Urban Drainage Systems (SuDS) that can reduce peak flow, collect and retain water and improve groundwater recharge. Most previous research has focused on the unsaturated infiltration rates of swales without considering the variation in infiltration rates under extreme …
