The Gammelsbach is an approximately 13 km long brook in the Odenwald , which flows into the Neckar from the right and north to the west of Eberbach .

geography

course

The Gammelsbach rises in the Odenwaldkreis in southern Hesse after the sports fields on the southern edge of Beerfelden on the edge of the Seewiese road . The stream flows very steadily south. Less than half a kilometer after its source begins its valley, which is often wooded down to the edge of the floodplain and steeply dug between the Hirschhorner Höhe in the west and the Sensbacher Höhe in the east, in which the B 45 accompanies it to its mouth. About two kilometers below the source, the settlement area of ​​the community of Gammelsbach begins , which stretches for almost four kilometers as a mostly narrow and partially interrupted band along the stream; In this area the lower slopes and larger side valleys are often free from forests. About seven and a half kilometers after the source, the Gammelsbach crosses the state border to Baden-Württemberg , after which the entire valley is completely forested before the floodplain opens again narrowly. On the last kilometer, in the valley, which has remained narrow until the end, the elongated buildings of a chemical company move south next to the stream. Then the Gammelsbach flows from the right, about one kilometer west of the outskirts of Eberbach and below the large northern Neckar arc, into the Neckar, which here again flows southwest .

The course runs through the districts of Beerfelden and Gammelsbach in the town of Oberzent in the Odenwald district in southern Hesse and through the urban area of Eberbach in the Rhein-Neckar district in Baden-Württemberg . To the right and west of the lower reaches, the Oberzent district of Rothenberg also has a share in the right valley slope and the side valleys on this side.

Catchment area

The catchment area covers about 33.2 km² and, according to the natural spatial structure of the Odenwald, lies with the vast majority in its sub-area Central Sandstone Ode Forest and the rest near the mouth in the sub-area Odenwald-Neckar Valley .

It has roughly the shape of a north-south oriented long rectangle with a southern nose placed on the eastern south side. From north to south it stretches almost 11.5 km long, while perpendicular to it it remains under 4.5 km wide everywhere. Down the valley, the stream comes closer and closer to the mouth of the eastern watershed. The greatest height in the catchment area is in the north on its eastern border on a nameless elevation of the northern Sensbacher Höhe near the pass road from Beerfelden to Ober-Sensbach , 557.8  m above sea level. Reached NHN . Much further south is on the same ridge with 551.5  m above sea level. NHN on the Hohe Warte again almost reached this altitude coordinate. The western watershed on the ridge line of the Hirschhorner Höhe is less than 500  m above sea level everywhere . NHN .

The catchment area of ​​the Mümling connects to the north of the source near Beerfelden , beyond the northern part of the eastern watershed the Sensbach drains to the Itter , which then competes via smaller tributaries on the other side of the southern part, before the immediate catchment area of ​​the Neckar, which receives it, connects in the far south . In the west, the Finkenbach, which is almost parallel to the Gammelsbach, flows over the short Laxbach to the Neckar below the Gammelsbach tributary.
