and now for something completely different

Thalweg

noun The line defining the lowest points along the length of a river bed or valley. From German Talweg, Thalweg : Tal, Thal, valley + Weg, way

I finished my acnh town a few months ago and then procrastinated on updating the dream address for ages, but! I’m actually really proud of it and put a LOT of work into it, so I’d be really stroked if people came to visit and let me know what they think!

Featuring densely forested mountain ranges, a winding river down in the valley, a quiet lakeside town, and mysterious ruins. Rural and natural/overgrown vibes all around.

Landscape Language Thalweg (n) – the line that traces the lowest points along the length of a riverbed or valley Along the thalweg, a river flows its fastest as it follows its deepest channel.  The thalweg connects the lowest points of a river, and is a natural dividing line in a valley. Thalwegs have been used many times as natural borderlines between properties and even countries. However, the exact geography of a thalweg can change as often as the river changes course. The braided rivers of Mount Rainier fluctuate more than most, making their thalwegs poor borderlines. NPS photo of the Nisqually River and Glacier Bridge, 10/21/2014. A white ribbon of a river weaves through a wide rocky valley floor and underneath a bridge. ~kl

Thalweg

The thalweg is the line of greatest depth in a valley. It is used by lawyers and hydrologists; the former to solve boundary disputes and the latter to describe the line of deepest, fastest, and therefore most erosive water in a river.

thalweg, /ˈtälˌveɡ/. in hydrological and fluvial landforms, a line drawn to join the lowest points along the entire length of a stream bed or valley in its downward slope, defining its deepest channel, and thus, the natural direction (the profile) of a watercourse.

Even in highly dynamic natural river corridors, analyzing static landscape patterns is a necessary first step. For example, combining data from aerial photographs, digitized maps, and detailed field measurements revealed a remarkable spatial heterogeneity in the glacial flood plain of Val Roseg. The channel network within the glacial flood plain by no means consists of uniformly cold, highly turbid waters. A landscape approach enabled us to identify 6 distinctive channel types, based on the correspondence between connectivity and physicochemical attributes (Tockner et al. 1997). Channel types in the Val Roseg include (1) the main thalweg channel, (2) side channels, (3) intermittently-connected channels, (4) groundwater channels (alluvial and hillslope-fed), (5) mixed channels carrying water from different sources, and (6) tributaries.

En voilà un joli thalweg "très dynamique" :) !
