The impact of extreme rainfall on the shallow subsurface in Dakar: new evidence from the AfriWatSan observatory in Thiaroye


In August and September of 2020, extreme rainfall events caused flooding in Dakar. A new monitoring facility in the AfriWatSan urban groundwater observatory in the Thiaroye area of Dakar yields new insight into the hydrological impacts of such events. Located beside a large septic tank beneath a school toilet block, the facility provides high-frequency observations of rainfall and changes in the quantity and quality of soil moisture flowing through the unsaturated zone to shallow groundwater in Quaternary sands.   During a wetter (535 mm) than normal (450 to 500 mm) rainy season in 2020, two extreme rainfall events were observed…

Setting up a field laboratory during the COVID19 pandemic in Dakar


In Dakar, field work under AfriWatSan continues. To assess mechanisms of water and pollutant transfer from on-site sanitation systems to groundwater in the shallow aquifer of unconsolidated Quaternary sand, PhD student – Abdoulaye Pouye – has established a field laboratory in the unsaturated zone of a suburb of Dakar (Keur Massar). Here, on-site sanitation facilities (squat-toilets) have been replaced and a network of probes (electrical conductivity, temperature, soil moisture) and suction cups (to sample interstitial water) have been installed and tests have been carried out to develop a baseline of measurements before use of squat toilets resumes after the COVID19…

Behind the paper, World Water Day 2020 – Groundwater and climate change revisited: informing adaptation in a warming world


Recent research has identified the natural resilience of groundwater to climate change and our tendency to deplete this invaluable resource. It’s time we understood, valued, and governed groundwater as the vital adaptation to climate change that it is.   Groundwater flowing within the geology beneath our feet is the world’s largest liquid store of freshwater. Its volume in most countries in Africa for example, is estimated to be 10 to 100 times greater than that which flows annually through their rivers, lakes and wetlands. The widespread distribution and inter-annual storage of groundwater play an essential role in sustaining ecosystems and…

AfriWatSan at the International Symposium on Isotope Hydrology – 20th – 24th May 2019, Vienna, Austria


AfriWatSan participated in the International Symposium on Isotope Hydrology held from 20th to 24th May 2019 in Vienna, Austria. As announced on the International Atomic Energy Agency (IAEA)’s website, this  15th symposium  aimed “to facilitate the exchange of information and knowledge among water and environment professionals from developed and developing countries in order to advance the understanding, collaboration and capabilities to respond to the rapidly changing global environment.” The conference’s website indicates that, at the symposium, water experts looked at new isotope techniques that could help address widespread pollution problems among others. They also shared examples of how countries, cities…
