Settlement chamber on the Swabian Alb (3D)
About this app
An idealised settlement chamber on the karst plateau of the Swabian Alb: fields, pasture and water each set a limit, and the minimum wins. A dew pond in a sinkhole raises it, more hill land does not — and from the burial mound on the hilltop you see 60 % of the chamber, from the best field hollow 10 %.
With explain mode: an AI tutor walks you through the app, points out what matters in the scene and answers your questions.
Water in karst country
The plateau of the Swabian Alb in south-west Germany is limestone. Rain seeps away into fissures and sinkholes, funnel-shaped hollows in the rock, so there are hardly any streams on top. Springs only emerge at the Albtrauf, the escarpment along the edge of the Alb, often where impermeable marls begin. On the plateau, dew ponds (Hülen) helped: ponds whose floor is sealed with clay. They are well documented for the Middle Ages and later, not securely for the Bronze and Iron Ages. How many people a settlement chamber can feed therefore depends less on its area than on the scarcest factor: fields, pasture or water in the dry late summer.
What the app shows
A terrain block shows an idealised, not real settlement chamber: a plateau with hilltops, a dry valley and four sinkholes, plus the wooded escarpment with a spring in the valley below. The cut face shows limestone beds above marl. The layers water, soil, land use and view recolour the terrain. A model with stated assumptions gives one number of people that can be fed for fields, pasture and water; the minimum is the limit, and a barrel with three staves makes it visible. Farmsteads appear and disappear with the limit, and unused farmland stays forest. Burial mounds stand on hilltops and by the long-distance track.
Try it yourself
Tap a ring and build a dew pond in the sinkhole: the limit rises from about 70 to 160 people, and new farms appear next to the pond. With a second pond the pasture runs short. Add the hill land: fields and pasture grow, but the limit stays while water is short. Compare spring, late summer and a drought year, and change yield, fallow and livestock. In the view layer you can see that a burial mound on a hilltop overlooks about 60 % of the chamber, the best field hollow only about 10 %.
Frequently asked questions
- What is a dew pond (Hüle) on the Swabian Alb?
- A Hüle is an artificial pond on the karst plateau of the Swabian Alb whose floor is sealed with clay so that rainwater does not seep into the limestone. Such ponds supplied villages with water for people and livestock until the Alb water supply scheme began around 1870. They are securely documented for the Middle Ages and later.
- Why are there hardly any streams on the Swabian Alb?
- The plateau of the Swabian Alb is karstified limestone. Rainwater dissolves the rock and quickly seeps into fissures, caves and sinkholes. It drains underground and only comes back to the surface in springs at the escarpment or in deeply cut valleys.
- What is the law of the minimum?
- The law of the minimum, associated with Justus von Liebig, says that growth is limited by the scarcest factor, not by the total of all factors. For a settlement this means: if the water is only enough for 70 people, more fields change nothing. Only when water increases does another factor become scarce.
- What can I do with the settlement chamber app?
- You build dew ponds in sinkholes, switch season and area, set yield, fallow and livestock, and see which factor limits the number of farms. The view layer shows what can be seen from a burial mound or from a field hollow. An explain mode walks you through the key steps.
