I saw this book on another post - and so went and found a copy at a 2nd hand book shop…
Looking forward to lunches at work with a cup of tea and maybe a couple of rainy Sundays at home…

I loved this scenic view in Capitol Reef National Park because of all the layers of flora and rock formations from a foreground of shrubs and grasses to distant background red rock cliffs. The scene shows the rugged beauty of the desert environment.

Rugged cliffs in Capitol Reef National Park rise dramatically to contrast with the sky’s delicate wispy clouds. Early morning light highlights the multiple layers of sedimentary rock that record 200 million years of geologic history. Processed in black and white.

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.)

Details of curving rock formations display intricate patterns and rich hues along the edge of Lago Argentino in the Patagonia region of Argentina. Sparse greenery is along the top, contrasting with the textured surface below. Processed with painterly finish.

#Development of Wind farms (not the turbines themselves) could wipe out Scotland’s freshwater pearl mussels

“Pearl #mussels are extremely sensitive even to small changes in the river catchments such as increased #erosion or changes of flow regimes.

“Where there is a risk of this happening because of new developments, the impact must be critically assessed.

The National · Wind farms could wipe out Scotland's freshwater pearl musselsBy Laura Pollock

There is a stream down the hill from my house. It winds down a a valley to the larger stream I mentioned yesterday
The valley has been used by folks for a couple of hundred years, there is a main road that crosses the stream several times and many houses built right up to the banks.
Undercutting has been a problem due to the apparent increase in storm intensity over the last decade or so.
Erosion is a constant and various means have been attempted to keep it under control. Down the street from me is a concrete lined section.
This particular job is a continuation of a more recent attempt using more “natural” methods to keep things in check.
The stream has been carrying a pretty heavy silt load for the last couple of months. It had previously run pretty clear.
This is some of the current silt control. The pipe is carrying the stream from the other side of the construction area. Does not seem to be working all that well.
It could be worse.

Strandbeest Evolution

Theo Jansen’s Strandbeests are massive, wind-powered kinetic sculptures designed to roam Dutch beaches. Conceived in the late 1980s as a way to kick up sand that would replenish nearby dunes, the beests have grown into a decades-long obsession for the artist and his followers. This Veritasium video charts the development and evolution of the Strandbeest from its original concept through Jansen’s increasingly self-sufficient versions. I found the leg linkage of the Strandbeest especially fascinating. How neat to find a relatively simply proportion of linkages capable of turning a small crank’s motion into a stable walking gait. Anyone else feel like building a miniature Strandbeest now? (Video and image credit: Veritasium)
