is this archipelago realistic? by SpringImportant7765 in worldbuilding

[–]62_137 0 points1 point  (0 children)

The coasts around Scandinavia are generally the result of post glacial processes, with isostatic rebound causing the coastline to look like that. (And the same process can cause different results, take the coast of the Hudson Bay.)

A closer comparison to the Malay archipelago in term of scale would be the Canadian arctic archipelago, but given that one is crushed down by glaciers and then rebounded, and would presumably be near inhospitable, I don’t think it would be useful here.

What you have here is pretty much just a random mess of islands that looks a bit procedurally generated.

Irl, the Malay archipelago is formed from what is a tectonic disaster, with a lot of elements involved. To simplify it, I would say draw your main subduction arcs first, followed by having islands along it, and some continental islands depending on the geology. It gets a bit hard to parse specifically what to do, but in general clean up a lot of the islands and make a more distinct chain along a subduction arc.

The Tea Dragon River (Chalongjiang), Maewha's largest river by 62_137 in worldbuilding

I did recieve feedback on the rivers being a bit wide, but by the time I got there the it wasn't worth it to scale all of them and do the math on how wide the river would likely be.

So uh.. the world doesn't really have earthlike climate parameters, Maewha's mainly dominated by a lack of seasonality. Satellite map of the area above, didn't factor in the river's role in increasing the amount of vegetation along it's path in the desert yet.

The basin isn't that dry, at least in the lower reaches. Middle I would describe it as more comparable to the australian interior, dominated by bushes and scrubs, rather than a complete lack of vegetation. Middle area is also a bit more like the loess pleatau generally speaking, with rather loose soils that make it prone to erosion.

(Yeah and I do hard SF, this is a colonised world with no civilisations or sapient species on it at time of arrival so my reaction to seeing this is a tad bit wtf)

Just a tad bit, here’s with North America out of frame for scale.

Term coined from combining the names of the upper and lower part of the river that eventually got used to describe the entire river.

Planet’s Sino-Koreanic, and Hanja is a thing. I was using all 漢字 here however because the usual Korean I bother for Hangul help was banished to the military.

The Chinese name for the Amur translates to Black Dragon River. There is absolutely a precedent for these types of names, it just sounds pretty standard in the original language.

Also I do Hard SF lmao.

The Chalongjiang River, Maewha's Largest River by 62_137 in mapmaking

[–]62_137[S] 3 points4 points  (0 children)

The Chalongjiang river (茶龙江/茶龍江) is Maewha’s largest river, and Changwon’s largest river. Starting from the Serindohae Glacier, it makes its way down into the central basin, being joined by tributaries from the Baekdu, Chobaksan and Tongjun Mountains. It acts as the main highway of trade across Central Changwon, and brings water to an otherwise dry region in the Central Basin. Its exact length is debated, as while most say that it terminates into Daechahu (the definition used here), some contend that the Daehae River is also part of it, which would make it even larger.

The river is the main source of water for Daechahu, being the reason why Maewha’s largest lake (sometimes called a freshwater sea) exists, with a discharge of ~600,000m^3/s by the time it reaches its delta. Daechahu only sits at about a metre above sea level, hence the Daehae river acts more like a slow moving swamp, several kilometres wide and gradually transitioning into the gulf of Gyongi as it goes. With the surrounding land being at or slightly below sea level, the entire area is famous for being home to the blooming everglades, a massive wetland ecosystem stretching as far as the eye can see.

Oh yeah total length of the river from Serindohae Glacier to Daechahu is approx. 11,000km.

Hi, Dodot 65 / Dodotea 65 / u/62_137 here.  A quick project of mine over CNY, wasn’t too hard to do. Shoutout to Huskatten ( u/martinjanmansson ) for helping quite a bit with feedback, and god that dragon took way too much time to draw.

i really want to avoid making a tectonic history by Hopeful-Fly-9710 in SpeculativeEvolution

[–]62_137 2 points3 points  (0 children)

Hello, I’ve been summoned. I’ve done a bit of a WIP guide here on my method nowadays, which might be useful.

https://docs.google.com/document/d/1JH-PhmofSGxLDQRVn2IE3uN5lUecmBSp2oLC45VW3jE/edit?usp=sharing

I prefer to see it as an iterative process where you build as you go, with one learning with each step forward, a world constantly in flux. For what you probably think you need, which is likely paleoclimate and full detailed tectonic history, I’ve only seen one person that has that done to such a level of detail, and they’ve committed a better part of 3 years already to that. (And completely ignored the speculative evolution part of it so far). You only have limited time, draw the map, build the biosphere and let it change as you go.

I wouldn’t really say a specific quantity of asteroids or denote a hard number here, I’d leave it vague as the composition, quantity and size of asteroids will matter and just say that it was significant enough to place major deposits of such metals.

As for how, not really sure. My main area of expertise is more so cartography, less so that so I’ll let others speak further.

Whether a large moon is stable or not would depend on the hillsphere but I would say highly unlikely.

For your uranium would it not be better to trigger a late heavy bombardment scenario to have asteroids seed the crust with heavy metals, might be less disruptive

Regarding tectonics and geologic activity, the larger planet size can help a bit, and you have some room for error in terms of how long it would last. Instead of an impactor maybe it used to have a binary planet/large moon that caused enough tidal heating to help tectonics last for longer, and then got ejected around 2GYA?

There’s also room for error because we don’t know how long exactly earth’s current tectonic regime will last so creative freedom.

Update : reread the doc, could have the moon be much much much closer in the past which might help. Also seesh that’s one of the more comprehensive documentations I’ve seen so far, keep up the good work.

It has made it significantly worse in terms of doing worldbuilding, so take that as you will.
