Morava-Dyje confluence
River confluences are well-defined points in terrain so I was highly motivated to visit this place where two important Moravian rivers join. Furthermore, it was also educational biological trip organized by my friend biology teacher.
Topologically it was a fully remote trip, i.e. deployment by train in Břeclav, tripping (in remote location) and rollback by train from Veselí nad Moravou (changing train in Brno).
Insects
- Cerambyx scopolii

- vine cellars
- little houses with blue band right above ground

History
- Šimerník

- Mikulčice
- settlement of Slavs during Great Moravian period
- high density of churches
- lookout tower (south horizon hindered by trees)
Geography
- Moravská Sahara
- sand sediments between Hodonín and Strážnice
- adventurous bicycle ride
- meadows in Bílé Karpaty
- steep terrain, high “grass” (~70 cm) and isolated trees (apple trees?)
- very high biodiversity
- direct flow of Morava river
- it used to be crooked with many meanders, it was straightened in 70s
- polder
- temporary dam that buffers water during floods
- weather
- confirmed prejudice that South Moravia has always nice weather
- there were clouds, however, they were stable and we hit no storm in the end
Industry
- Hodonín power plant
- used to burn local lignite (not to confuse with lignin), now biomass
- Moravské naftové doly
- little pumps in the fields that mine oil into tanks which are fetched from time to time
