. They have a distinctive geological origin and are enclosed by peninsulae, spits
Spit (landform)
A spit or sandspit is a deposition landform found off coasts. At one end, spits connect to land, and extend into the sea. A spit is a type of bar or beach that develops where a re-entrant occurs, such as at cove's headlands, by the process of longshore drift...

 and islands, leaving only narrow connections to adjacent bodden or the open sea. Freshwater inflow from the mainland and saltwater inflow from the open sea, which depends on wind direction and force as well as the proximity of the bodden to the sea, result in fluctuating salt gradients and distinctive ecosystems.

, resulting in lakes with depths of no more than 4-6 metres. Thermal and saline stratification is extremely unstable under these conditions, and bodden have the typical dynamics of small bodies of water with a sea connection, which is a rapid filling and draining due to tidal and wind action, and inflow of fresh water. The frequent movement of water can lead to a scouring effect, but can also with heavy pollution show a tendency toward eutrophication
Eutrophication
Eutrophication or more precisely hypertrophication, is the movement of a body of water′s trophic status in the direction of increasing plant biomass, by the addition of artificial or natural substances, such as nitrates and phosphates, through fertilizers or sewage, to an aquatic system...

. Due to erosion of cliffs and sedimentary deposition, the shape of the bodden coasts remains unstable. Sudden changes have been caused by stormfloods, which repeatedly closed connections to the sea or opened new ones in the past.
