Fluvial System Block Diagrams
--
I was looking to understand a fluvial system the other day, up in the high Arctic, as I looked at 3DEP remote sensed elevation data… I have always been fascinated by the how geology, water, weather shapes a landscape, including erosion (aka geomorphology if you will) – and realized how very much value fluvial block diagrams have as we try to conceptualise what has, is and will happen(ed.)

[those in the spatial hydrology ‘world’ have long been incredibly impressed by Dan Coe’s imagery and cartography, here is a wonderful article on cartography & science with his visual arts quality]
“Cartographer Daniel Coe uses relative elevation data, primarily from plane-mounted lasers called lidar, to visualize Earth’s natural features, like rivers and floodplains. His stunning river maps reveal stories hidden in historical sediment and past channels carved by the water, as it twists and turns through both landscape and time…”

Drought conditions persist in Illinois, contributing to record low water levels on the Mississippi, and impacts on the shipment of grain harvests.

Are drying #rivers a warning of #Europe's tomorrow?

by Paul Hokenos

"Across southern #Romania, much of which relies on the #Danube for fresh #DrinkingWater, hundreds of villages are rationing water supplies and curtailing the irrigation of #farmland that Europe relies upon for #corn, #grain, #sunflowers, and #vegetables. The cruise ships that normally ferry tourists along the iconic waterway are docked. In the first six months of 2022, Romania's #hydropower utility #Hidroelectrica generated a third less electricity than it normally does. And Romanian #wheat farmers say that drought has cost them a fifth of their harvest. Romania is one of Europe's largest wheat producers, and all the more important for the international market in light of Russia's blockage of much of Ukraine's wheat exports.

"'At towns up and down the Danube, #drought and #ClimateChange take on an existential meaning,' explains Nick Thorpe, author of The Danube: A Journey Upriver from the #BlackSea to the #BlackForest. 'In contrast to city dwellers, they're having this disaster unfold before their eyes.'"

"Scientists say that the economic cost of the rivers' decimation is only part of the problem. The less water in the water system as a whole, explains Gabriel Singer, an ecologist at University of Innsbruck, Austria, the less dilution for #salts and the slower a river flows. This leads to higher #saline content and #HigherWaterTemperatures, which can be lethal for many species of #Riverine life, such as Danube #salmon, b#arbel, and European #grayling, among many others.

"Higher temperatures also feed #AlgaeBlooms, Singer explains, which can be #toxic for river systems. This is what has happened in several German rivers, including the Moselle and Neckar, as well as perhaps the Oder River, where in mid-August more than 100 metric tons (220,000lbs) of dead fish – among them #perch, #catfish, #pike, and #asp – washed up on its shores within a week. (Experts are currently investigating the cause of the die-off.)"

Are drying rivers a warning of Europe's tomorrow?

Europe's rivers fell to historically low levels during a long, ferociously hot summer. Is a sign of things to come?
