Hydrology Paper (Book) of the Day @limnologic.bsky.social on the extreme engineering of dams, reservoirs, and water pipelines: why the Vajont Dam was so challenging to build; the San Roque reservoir in the context of engineering history; and a water supply pipeline as part of a large-scale scheme.

Line graph time series of monthly mean surface temperature anomalies for the Northern Hemisphere region only. Every month is shown from 1940 to July 2025. There is a long-term warming trend in all months of the year.
Line graph time series of monthly mean surface temperature anomalies for the Southern Hemisphere region only. Every month is shown from 1940 to July 2025. There is a long-term warming trend in all months of the year.
Line graph time series of monthly mean surface temperature anomalies for the Arctic region only. Every month is shown from 1940 to July 2025. There is a long-term warming trend in all months of the year and a strong seasonality in terms of the magnitude of the anomalies.
Line graph time series of monthly mean surface temperature anomalies for the Antarctic region only. Every month is shown from 1940 to July 2025. There is a long-term warming trend in all months of the year, but less obvious than the other regions.
Comparing the different seasonality and trends in the magnitude of monthly temperature anomalies since 1940 for the Northern Hemisphere, Southern Hemisphere, Antarctic and Arctic. There are significant differences in the rate of long-term warming (blue to red lines).

Poster for 90 minute workshop on HOW TO DESIGN BETTER EXPERIMENTS, by Mridul Thomas & Ravi Ranjan. Details: September 23rd 16:00 CEST ; 14:00 UTC Description: Experimental designs can make or break an experiment. A good experiment has a clear goal and efficiently uses experimental resources to achieve that goal. In this workshop, we will review what experiments are for, basic and advanced principles of designing experiments, and how to use simulations to evaluate designs before actually doing the experiment. Weโll do a moderate amount of coding in R and so experience with this would be helpful but is not required. We intend to have small-group discussions to help participants develop their own experiments, and encourage participants to think of a specific question they would like to answer with an experiment.
@raviranjan.bsky.social & I are teaching a free online workshop with on experimental design for environmental scientists on the 23rd.
We'll focus on using simulations to evaluate how well different experimental designs help achieve your goals.

Schematic diagram showing the influence of sea-level change on fluvial transverse and axial drainage systems in the Taiwan Strait. (A) PalaeoโChoushui River sediments were transversely transported from wedge-top areas to the emergent forebulge during the Last Glacial Maximum. Along the east side of the forebulge, some fluvial sediments were transported southwards and axially via the linear sediment conduit of the connected river valleyโsubmarine canyon to the South China Sea. (B) Beginning around 9.5โka BP to the present sea-level highstand, the narrow seaway east of the forebulge became a foredeep filled with shallow marine sediments. The Choushui River empties sediments from wedge-top areas into the Taiwan Strait, where they are redistributed and transported mainly by the north-flowing Taiwan Warm Current, resulting in an axial sediment dispersal pattern.
Let's say you have a big river, and active tectonics, and strong ocean currents, like, for example, around Taiwan, there are going to be a lot of modes of sediment dispersal, and they will alternate over time. ๐งชโ๏ธ

A flyer for an AGU 2025 session titled, "A082: New Perspectives on the Exchange of Reduced Nitrogen Between the Atmosphere, Land, and Water from Remote Sensing, in situ Measurements, and Modeling Approaches" The description reads, "Reduced nitrogen from source to impact! From wildfires to agricultural inputs, diverse sources of reactive nitrogen drive significant ecological changes including eutrophication, harmful algal blooms, and aquatic food web disruption across multiple environmental systems. Submit an abstract to our interdisciplinary session exploring atmospheric, terrestrial, and aquatic perspectives. We welcome contributions using remote sensing, field measurements, and modeling approaches that span complexity and spatiotemporal scales. Sections: Atmospheric Sciences, Biogeosciences" The conveners are Dr. Matthew Davis, Dr. Kimberley Corwin, and Dr. Lauren Magliozzi of Colorado State University. There is a QR code for the submission link, and the deadline is listed as 30 July 2025. The text is black on white boxes with blue accents, and the background features a blue sky with large, white clouds.

Digital elevation model of the Grand River, South Dakota, USA. River floodplain in blue (high) to white (low), the rest of the landscape in orange (high) to green (low). The river meanders, the landscape on both sides of the floodplain is eroded with finger-like gullies.
A nice river, somewhere, meandering through a bit of glacial deposits and cutting into Upper Cretaceous shale and sandstone.

Wow! Since 2005, Paris has slashed air pollution by 55% - a staggering win for public health and climate. How? Bold green urbanism. The city curbed car traffic, expanded bike lanes and boosted public transport. When people and planet are prioritised, the air gets cleaner and lives get better.
