What forms do groundwater flow equations have when Dupuit supposition is not considered?
Modeling & PredictionThe governing equation for three-dimensional groundwater flow that relaxes the Dupuit assumption is known as the Laplace equation. This equation describes the distribution of hydraulic head within the aquifer and takes into account both the horizontal and vertical components of the flow. The Laplace equation is typically expressed in terms of spatial coordinates (x, y,
Simulating a Control Earth: The Importance of Model-Based Controls in Earthscience
Human ImpactSimulating a Control Earth: Why Model-Based Controls Are a Game-Changer in Earth Science The Earth’s climate is this incredibly complex, ever-shifting puzzle, and getting our heads around it is key if we want to predict what’s coming and, frankly, avoid some serious trouble. Earth system models (ESMs) are like our super-powered tools for tackling this
What are those arrowlike underwater structures for?
Human ImpactDecoding the Mysteries of Arrow-Like Underwater Structures Ever stumbled upon weird, arrow-shaped things while exploring underwater? Maybe you saw them diving, or perhaps they popped up on a sonar scan. They’re not just random rocks, that’s for sure! These structures usually have a specific purpose, from old-school fishing tricks to modern ways of helping sea
Exploring Land-Only Temperature Datasets for Climate Change Research
Climate & Climate ZonesExploring Land-Only Temperature Datasets for Climate Change Research Okay, so the Earth’s climate is changing – no surprise there, right? But really digging into the details of how and why requires some seriously reliable data. We often hear about global temperature datasets, the ones that lump together land and ocean temps. Those are great for
How are scatterometer observations standardised before being fed into reanalysis models?
Energy & ResourcesOkay, so you’ve got scatterometer data, right? It’s super important for figuring out past weather and keeping tabs on our climate. But before we can just toss it into those fancy reanalysis models – the ones that reconstruct old weather like some kind of meteorological time machine – we’ve got to clean it up and
The Curious Case of High Altitude Cities and Their Elevated Atmospheric Pressures
Weather & ForecastsThe Curious Case of High-Altitude Cities: Why the Air Up There is a Whole Different Story Atmospheric pressure. It’s one of those things most of us don’t give a second thought to, right? But if you live way up in the mountains, in a city clinging to the sky, it’s a different ballgame. It’s not
