The Röhlinger Sechta , also called Sechta for short , is the right tributary of the upper Jagst in the Baden-Württemberg Ostalb district . With a length of around 20 km and a catchment area of ​​around 90 km², it is the most important tributary on the upper reaches of the Jagst. It should not be confused with the Schneidheimer Sechta , which competes in the upper reaches of the river and flows into the Eger .

geography

Stream

The Röhlinger Sechta arises on the southwestern outskirts of Pfahlheim from the confluence of the right Sonnenbach and the left Weiherbach . The Sonnenbach , which is dammed into a lake north of Pfahlheim, comes from the northeast, the Weiherbach from the southeast. The combined stream runs roughly in the direction of the larger upper reaches to the southwest. Below the hamlet of Erpfental , the powerful Ellenberger Rot flows from the right ; with a catchment area of ​​25.0 km², it is only 1.4 km² behind the Sechta itself up to this point; it drains half a dozen reservoirs in a wooded landscape. In Röhlingen , the Schlierbach, which is over seven kilometers long, flows from the right. Of the smaller tributaries below, the right Hirschbach below Röhlingen is less than five kilometers and the left Killingerbach in the next town of Haisterhofen is almost four kilometers long. Where immediately after this hamlet the A7 motorway spans the valley basin, the Sechta swings to the west and then crosses the Rainau village of Dalkingen. Almost two kilometers west of the village, the Röhlinger Sechta flows from the right into the upper Jagst , between its outlet from the Buch reservoir and the Rainau hamlet of Schwabsberg, which is about a kilometer down.

From a little above Dalkingen to the mouth, dams accompany the bed of the Sechta on both sides .

Data

The Sechta is the most important tributary of the upper Jagst. According to some, it is the stream that turns young Jagst into a small river. At the mouth it even has a larger catchment area of ​​90.3 km² than the Jagst itself, which is only 82.9 km². Between 1953 and 1998, the Sechta carried an annual average of 0.75 m³ / s of water. Nevertheless, the Jagst at the mouth gives the impression of being a little richer in water, which is perhaps due to the discharge from the Härtsfeld on the Swabian Alb , especially the runoff from the Fuchsmühlenweiher in Lauchheim. Relevant estimates are fraught with great uncertainty.

On the LUBW website , the length of the Sechta is given as 20.1 km, but there with the Ellenberger Rot as the source river; with the Sonnenbach as the source river, the Sechta itself is about one kilometer less in length than with the Ellenberger Rot, which in turn has about 1.4 km² less catchment area at the point of confluence. Nonetheless, their runoff is likely to be greater on average, because in their upper catchment area on the towering Hornberg there is incline rain, while the lower catchment area of ​​the upper Sechta lies east of it for the usual westerly winds in the rain shadow of the Hornberg. The underflow of the Sechta that arises at the Red tributary continues to flow in its own inflow direction. The criteria commonly used to determine the main strand on the upper reaches are therefore in contradiction to one another.

history

The route of the Upper German-Raetian Limes stretches for a long time on both sides of Sechta and Sonnenbach . About one kilometer northeast of Halheim is the area of ​​the former Numerus Fort Halheim , which stands out in the landscape as a hedge that traces the former outer walls.

    The length to the mouth was measured because the stationing of the gauge, which is apparently increasing downstream, does not fit well with either of the two headwaters and the corresponding overall lengths.
