I’m delighted to share that our latest research has just been published in HESS. We developed an unsupervised workflow to estimate river surface velocities from videos. Testing on 11,000+ videos against 274 gauging measurements showed excellent agreement. hess.copernicus.org/articles/29/...

Unsupervised image velocimetry for automated computation of river flow velocities

Abstract. Accurate, long-term measurements of river flow are imperative for understanding and predicting a broad range of fluvial processes. Modern technological advances are enabling the development ...

Landsat could use your support. The mission's 50+ year data continuity is at risk. If you believe contacting elected representatives does anything, now would be a good time to apply pressure. 🛰️📡

This image cannot be shared enough. This is what our country would look like if we stop pumping water out of our polders. And in the meantime, we have closed all but one earth science departments, because it’s a little but more expensive than the average study. What could possibly go wrong.

For geomorphologists going to EGU, here is your one-page overview of all of the GM sessions and activities next week! Looking forward to a week of free and open science, EDI discussions and activities, and plenty of talk about climate change...

Geomorphology session overview, 28 April - 02 May, 2025. Below are tables for each day showing the GM sessions, times, and rooms for EGU25.

TopoToolbox 3 has some cool new functions. Here's how to export stream networks to shapefiles (and kml): topotoolbox.wordpress.com/2025/04/09/c... #TopoToolbox #MATLAB #terrainanalysis #geomorphometry #geomorphology

Converting stream networks to shapefiles in TT3

What’s new in TopoToolbox 3? Well, we have restructured the toolbox a lot, making distribution and installation easier. However, there are also some new features. One of these features is the…

The DOGE firings have nothing to do with “efficiency” or “cutting waste.” They’re a direct push to weaken federal agencies perceived as liberal. This was evident from the start, and now the data confirms it: targeted agencies overwhelmingly those seen as more left-leaning. 🧵⬇️

Scatterplot titled “Empirical Evidence of Ideological Targeting in Federal Layoffs: Agencies seen as liberal are significantly more likely to face DOGE layoffs.” • The x-axis represents Perceived Ideological Leaning of federal agencies, ranging from -2 (Most Liberal) to +2 (Most Conservative), based on survey responses from over 1,500 federal executives. • The y-axis shows Agency Size (Number of Staff) on a logarithmic scale from 1,000 to 1,000,000. Each point represents a federal agency: • Red dots indicate agencies that experienced DOGE layoffs. • Gray dots indicate agencies with no layoffs. Key Observations: • Liberal-leaning agencies (left side of the plot) are disproportionately represented among red dots, indicating higher layoff rates. • Notable targeted agencies include: • HHS (Health & Human Services) • EPA (Environmental Protection Agency) • NIH (National Institutes of Health) • CFPB (Consumer Financial Protection Bureau) • Dept. of Education • USAID (U.S. Agency for International Development) • The National Nuclear Security Administration (DOE), despite its conservative leaning (+1 on the scale), is an exception among targeted agencies. • A notable outlier: the Department of Veterans Affairs (moderately conservative) also faced layoffs despite its size. Takeaway: The figure visually demonstrates that DOGE layoffs disproportionately targeted liberal-leaning agencies, supporting claims of ideological bias. The pattern reveals that layoffs were not driven by agency size or budget alone but were strongly associated with perceived ideology. Source: Richardson, Clinton, & Lewis (2018).

In this mountain biodiversity review, we emphasized roles of habitat creation, disruption, and oscillation in driving biodiversity. Additionally, we developed a set of geomorphic predictors that may influence biodiversity patterns, with the potential for application to other montane systems.
