Rivers

Recent research reveals climate change’s significant impact on river flow seasonality, particularly in the high northern latitudes, with about 21% of surveyed stations showing significant seasonal flow alterations.A recent study has found that climate change is impacting the timing of river flows, especially in the higher northern regions. River flow patterns, which shift with the seasons, are crucial for managing floods and droughts, ensuring water security, and maintaining the health of global biodiversity and…

The founder of Stanbic IBTC Bank Plc, Atedo Peterside, has expressed his dismay over comments made by Senate President Godswill Akpabio at the funeral of the late Chief Executive Officer of Access Holdings, Herbert Wigwe. The funeral, held in Rivers State, followed the death of Mr Wigwe, his wife, son, and others in a helicopter crash in the United States last month. In a post on his X page, Mr Peterside recounted that Mr Akpabio began his address by lamenting that former Anambra state governor and 2023…

As another season of tubing down Clear Creek in Golden beckons, the city is considering a novel approach to controlling the crowds that descend on the popular waterway: a reservation system. The discussions are still in the early stages and the system, if it moves forward, wouldn’t be implemented until 2025. But the mere idea of requiring people to sign up for a float down Clear Creek is a testament to the increasing number of people Golden has had to manage on the water in recent years, especially in the wake of a…

A team of scientists led by the University of Leeds analyzed…

Rivers of intense moisture wend their way through our atmosphere just as their liquid counterparts do across the land. Unfortunately the sky streams are much harder for us to see.Often a product of cyclones, atmospheric rivers can dictate where intense rain will fall, making their lack of visibility a problem. Understanding them grows increasingly important as our warming atmosphere soaks up even greater amounts of water, forcing these aerial waterways to change course.Until now, researchers relied on computer modeling…

Atmospheric rivers, filaments of intense moisture transport in the atmosphere, can now be automatically detected in satellite observations. Credit: NOAA Atmospheric rivers (ARs) are filaments of intense moisture transport in the atmosphere. These weather systems drive a large fraction of the extreme precipitation events over coastal regions. Detecting ARs in satellite observations has long been a challenging task due to the…

Stream Ordering: How And Why a Geo-Scientist Sometimes Needed to Rank Rivers on a MapLearn how to obtain Strahler or Shreve order on vector layerPreview image (by author)Dear reader, in this article, I would like to dive into one exciting hydrological topic. I will start with the picture:Figure 1.

In many regions, atmospheric rivers, like the one shown here in green, are expected to increase in frequency with climate change. Credit: NASA Ribbons of water vapor called atmospheric rivers wind through the troposphere, moving the planet's moisture from near the equator toward the poles. These aerial waterways are responsible for about 20%–30% of the annual rain and snow in parts of Europe and the United States and more than…

These gravel-capped fluvial ridges in northeastern Colorado were among the "fossil river" remnants studied by Nebraska geologists Jesse Korus and Matt Joeckel. The eroded remnants of ancient river channels provide important information about ancient hydrology, landscape changes and uplift of the Great Plains.
