The central Enz valley is the transition area between the Gäu to the south and the Stromberg to the north, as well as between the northern Black Forest to the west and the Middle Neckar region to the east. In Lomersheim there is the upper shell limestone and the lower Keuper (Lettenkeuper). The Enz brings quartz sand and red sandstone boulders from the northern Black Forest. The landscape form known as the valley meander is present today in the Lomersheimer Enztal as a strong S. Further to the east, the Enztal loops are even more pronounced. A karst phenomenon in Lomersheim, albeit unpopular but still worth mentioning, were the "Grottenlöcher". This is the result of subterranean gypsum and salt leaching in the middle shell limestone beneath the valley floor. In the first half of the 20th century, two of these holes served as a Lomersheim dump and were leveled. In 1980, another piece of ground about 6 m in diameter collapsed several meters deep in the 'Dokterle' area. With a few truckloads of excavation from elsewhere, the natural phenomenon was removed from the world of Lomersheim.
The central Enztal in Lomersheim also has some special features in terms of climate. ...
The increased risk of flooding in Lomersheim is not solely due to climatic conditions. The precipitation that falls in the Enz catchment area would not cause flooding in a predominantly forested region. The partial deforestation of the northern Black Forest in the course of settlement history as well as increasing soil sealing and land consolidation in the second half of the 20th century have had a very significant impact on the Enz and its water supply. The speed at which floodwaters flow away has doubled since the middle of the 20th century. Many floodplain areas of the Enz and its tributaries have been built on and reduced considerably by flood protection dams. A violent thunderstorm in the northern Black Forest can be seen about an hour and a half later from the cloudiness of the water and the rising water level of the Enz in Lomersheim, where the flood dams in front of the Lomersheim Enzbrücke form a so-called bottleneck before the water then reaches the narrow loops of the Enz valley."
