🌊✨ Exciting news! At #RCEM2025, there will be a dedicated session for #WICGE (Women in Coastal Geoscience & Engineering), fostering inclusion & visibility in coastal research.

On this #11F, let's celebrate and amplify women in science! 💙🌍 #WomenInSTEM #CoastalScience

In @NatureClimate, we show that a year above 1.5 °C signals that Earth is most probably within the 20-year period that will reach the Paris Agreement limit.

6 and the last. While we should not underestimate the benefits of groundwater restoration (to ecology and ground subsidence mitigation), its unanticipated risk should raise more awareness for local residents, structure designers, and risk evaluators...

How can the restored groundwater table change the earthquake risk? Our work published at
@NatureComms made the first cut on this issue. (https://t.co/VD9ZyJtmTE) In short, the restored groundwater table INCREASES earthquake-induced liquefaction extent and severity. 1,

5. Considering the similar urbanization process worldwide, i.e the pattern of the sync extraction-construction and a later restoration, this case provides a fair warning to (re)evaluate the earthquake risk of the region with recovering groundwater tables.

4. In this study, we used Beijing as a demonstration where the South-to-North Water Diversion Project （the world's largest）significantly recovered the previously low groundwater table. Its earthquake-induced liquefaction extent and severity has drastically increased

3. As groundwater restoration projects kick in, the shallower, rising groundwater table facilitates a granular phenomenon called soil liquefaction whereby shaking ground builds up excessive pore pressure in the saturated soil, which loosens grain contacts and their strength.

2. Together with urbanization, groundwater extraction is usually the first choice for the urban water supply, and its process syncs with the urbanization process. So, a large majority of urban structures were constructed on a lowering groundwater table

@bedform @sedimentology what happened???

[Qiusheng Wu @giswqs]

I am looking for the best open-source algorithm for converting a building raster to vector without oversimplifying the outlines, something better than the minimum rotated rectangle algorithm. Let me know if you have any recommendations. Thanks.
