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…”

Are drying #rivers a warning of #Europe's tomorrow?
by Paul Hokenos
13 September 2022
"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.)"

Opinion: #GorhamConnector plan threatens river #Ecosystem, #HeritageTrout
Building a new road along the banks of #RedBrook will render barren a unique stretch of riparian #shoreline – with all the adverse consequences you might expect.
by C. Ian Stevenson
February 27, 2024
"While proponents tout the toll-road Gorham Connector as promising to shorten commutes and relieve traffic pressure in #GreaterPortlandMaine, there has already been substantial pushback to the concept. Regardless of how much (or for how long) travel-based advantage the new roadway might bring, as proposed it will have pronounced, unambiguously negative effects to the area.
"Maine is known for its sense of place. Many components contribute to what makes the state unique and desirable. Among these is the built environment, such as the 13th-generation Smiling Hill Farm in Westbrook, which the proposed route threatens to erode, if not entirely extinguish, as an economically viable vestige of Maine’s once robust agricultural heritage. Others have amply sounded the alarm about this issue.
"But the route introduces other threats to the more naturalistic landscape. Starting at #SmilingHillFarm and running south-southeasterly to I-295 is a five-mile section of Red Brook that mostly nestles in #DenseForest. Between County Road and Running Hill Road, in particular, Red Brook occupies one of the few contiguous #undeveloped #Riverine stretches in #SouthernMaine. While unassuming in scale, Red Brook is nevertheless remarkable for supporting one of the last remaining native populations of #BrookTrout in this part of the state.
"The proposed road will immediately abut the river, sitting nearly on its banks, for as much as a mile south of the County Road Interchange. This will degrade habitat, destroying the trees whose overhanging foliage provides shade and cooling effects for these temperature-sensitive fish and creates shelter from predators. It will make barren riparian shoreline that supports the aquatic and terrestrial insects that provide the primary trout food sources. The road itself will also contribute oil, salt and other #runoff to the river, #polluting the water. As a result of these factors, this connector will likely #exterminate this population of brook trout.
"Why should we care about a small river and its brook trout? Although this is not the official state fish, the fishing community widely considers it the prize species to catch, with so-called wild populations assuming even more cherished status. Brook trout provide a link across generations and cultural traditions and belong to everyone. Human inhabitants of Maine – from the original #Wabanaki to European colonists to modern Americans – have been catching these 'native' fish for millennia. Other parts of Maine, especially further north and west, have healthy native brook trout fisheries, making Maine highly regarded nationally as a destination to catch them.
"The fact that Red Brook, in the heart of #GreaterPortland, belongs to this orbit is no small feat. Most of the area’s waterways have already succumbed to habitat loss, development, predatory introduced species, warming temperatures and increased flooding due to #ClimateChange. Red Brook provides an opportunity for future #Mainers who might not have access to brook trout streams further afield to enjoy this natural amenity. Even if you do not care about fishing, this road promises to annihilate a population of one of our state’s heritage species, as well as its scenic habitat that also contributes to #Maine’s sense of place.
"#PeterMills, the executive director of the #MaineTurnpikeAuthority, claims his organization has 'gone to great lengths to minimize impacts to Red Brook,' but clearly it hasn’t gone far enough under the current proposal. There are yet solutions.
"Citizens can express concerns at a hearing planned for March or via the Maine Turnpike Authority’s online portal. If the connector is to be built, planners need to re-route to establish a buffer zone between the connector and river – even a few hundred feet would have a positive impact. While less ideal than a complete reworking of the route, this would at least retain the primary shoreline flora and fauna and allow for run-off infrastructure. And we could re-route the road to save Smiling Hill Farm at the same time. Or better yet, we could re-consider the whole project’s merit entirely."

The Grizzled Giant squirrel over here once finished all ripe fruits near by, it then started to feed on the young leaves. I wonder how they manage to hold the balance on a tiny stem and especially when they goto the extreme end. Once eating the desired leaves are completed, it moved on to another branch either by strolling on the same branch or by jumping. #grizzledgiantsquirrel #mammals #wildlife #wildlifephotography #WildlifeConservation #frugivore #riverine #forest #nature
@MlleaPankhurst Role of beavers in Wyoming
https://youtu.be/mSbulwhYR9o
#Beavers #Beaver #riverine #wyoming #DraperMuseum
#wyoming and #virtual #webinar! At the next Draper Natural History Museum Lunchtime Expedition talk at noon on Thursday, Feb. 2, Jerry Altermatt from the Wyoming Game and Fish Department discusses the many positive benefits #beavers provide.
The free lecture is titled “Ecosystem Engineers: The role of beavers in restoring and maintaining Wyoming’s #riverine #ecosystems and takes place in the Buffalo Bill Center of the West’s Coe Auditorium.
Those who prefer to attend virtually via Zoom webinar may do so by registering at https://us02web.zoom.us/webinar/register/WN_HuVDtGykRoKnq31_DS-kqQ.
"When we imagine #streams in North America, chances are we envision water rippling over stones as it follows a groove. But as I had learned...that is a stream without beavers. Seen from above, a #riverine system with a healthy population of #beaver resembles a great spiderweb."--Leila Phillip, #Beaverland
