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…

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.)

I have been digging out my old copies of John McPhee's #books, dipping in, remembering what it was like to be a new #geologist, and how it has carried across into #spatial #data, #geomorphology, #geomorphometry, #hydrology, #landcover, #engineeringgeology, #environmentalscience, #landuse, #massmovement and so much more......
This one paragraph reminded me so strongly of that time,, although I cannot of course write as eloquently:
--
"I used to sit in class and listen to the terms come floating down the room like paper airplanes. Geology was called a descriptive science, and with its pitted outwash plains and drowned rivers, its hanging tributaries and starved coastlines, it was nothing if not descriptive. It was a fountain of metaphor—of isostatic adjustments and degraded channels, of angular unconformities and shifting divides, of rootless mountains and bitter lakes..."
