Salt oh length is the longest tributary of the Inn in Austria and Germany at 225 km.
It forms the border of both states on approximately 59 km length and has a catchment area of 6.700 km ². The middle Wasserabfluss at the Flussmündung amounts to 250 m ³ /s.

river courses
salt oh rises from alps at the slopes „ of the salt oh vulture in Austria into the Kitzbüheler “into approximately 2,300 meters over NN in close proximity to Krimml. In the upper run the river flows in a longitudinal valley furrow into west east direction to blackoh. Therethe central run swivels northward and breaks through in the ravine of the salt oh furnaces the northern lime high alps. In the underflow flows through salt oh the Salzburg and salt citizen the basin, afterwards the Alpine foreland and flows in the basin of over fields on a height of 344 meters over NN with Haiming intothe Inn coming from the west.
to naming
salt oh owes like also Salzburg its names of the salt navigation, to in 18. Century on salt oh was operated. Still 1791 were called the river (Hübner, 1791) Salza (today the name of a down-Austrian river);still older designations are Iuarum, Viarum, Igonta.
tributaries
in the upper and central run: Krimmler Ache, Obersulzbach, dry brook, Untersulzbach, have oh, Mühlbach, hell PUCB oh, Felberbach, Stubache, Kapruner Ache, Fu Ache, Rauriser Ache, Gasteiner Ache, Grossarlbach, Kleinarl brook, Fritz brook
in the underflow: Lambs, Almbach, Torrener brook, Tauglbach, Königsseeache, hall oh (largest feeder)
quantity of water and floods
at eight levels in Austria and two in Germany become constantly data tooWater level and discharge raised. The middle discharge quantity becomes larger river downward by the supplies salt oh:

thereby is salt oh the one of the larger rivers in Bavaria. As alpine rivermust take up salt oh the Wassermassen large with unfavorable weather conditions and long continuing rain. In the time of June until Septembers this leads regularly to floods, rarely also in the winter. The probably largest flood in the history of the city Salzburg to 25. June 1786 is througha flood mark in the old part of town occupies. On the Gedenktafel at the house of nature Salzburg it stands that the life cost salt oh in May 1571 the 2,226 persons and in the July of the yearly of 13 houses following on it and Stadl drug along. The largest quantity of water of the recent timeflowed with 2.300 m ³ /s to 14. September 1899 by the city Salzburg, to 7. September 1920 approximately 2200 m ³ /s. Floods are very rare in March, to 21. March 2002 led salt oh in Salzburg 1,060 the m ³ /s, a quantity, which arises about every two years, forthe month March however at least a 100-jähriges flood represents.
Already to 23. February 1899 has the k. k. Federal state government introduced to Salzburg a provisional regulation for the flood oh arranging service in the Herzogthume Salzburg. Today is for the warning of floods from the technical university Vienna developed Hydrologic information system to the flood forecast (HYDRIS) responsibly. Here both meteorological and hydrologic data flow, which permit a preliminary warning and by to flood co-ordinators a Abstau with the help of the chain of power stations middle one salt oh make possible.
adjustment of the Flussbettes
correcting branched out the originally far andstrongly dynamic game river 1820 were decided by a convention between Bavaria and Austria. A goal was the protection from floods as well as fixing the national border. In addition at that time the active navigation should be limited secured and the maintenance expenditure. The installation of several supporting force stages as well as the successful adjustmentnegative effects in addition, had: a ever stronger Eintiefung and a partial channel-like appearance. Because salt oh over the banks steps only rarely, it does not supply the Auen and the Auwald any longer with water. The Weichholzauen disappeared thereby, the Hartholzauen drains, thatGroundwater level sinks. The multilayered problems with the danger of the rapid resoling copy with substantial damage to buildings and infrastructure, resulted from the Eintiefung, strengthened in such a manner in the meantime that action need exists. A GermanAustrian working group is busy to compile solution strategies.
water quality
due to one1895 established and in 1960ern strongly extended paper and cellulose factory into Hallein white salt oh the 1977 the largest contamination up. Only starting from 1979 became by delimitation of the quantity of waste water, which can be introduced, (1979: 84t BSB5 per day (which about 1.4 million inhabitants corresponds); 1985: 54t; 1988:20t; 1990: 15t; 1999: 8t; 2002: 2t) interspersed and with the installation of a free from chlorine bleach 1991 improves the quality suddenly.
until 1999 the water quality lay starting from the factory with water quality class II III (critically loaded), until 1987 even only with III-IV. By thoseInstallation and/or. Improvement of the waste water purification in the autumn 1999 could be achieved for the first time the continuous water quality class II („small load “after the European Union water framework guideline) below Hallein. The reorganization of the waste water technology of the paper factory was locked at the end of of 2002 successfully, the since then daily introduced quantity waste water corresponds however nevertheless approximately25% of the entire dirt freight salt oh.
Within the range of the city Salzburg 1987 the employment of the large purification plant Siggerwiesen, which is appropriate for over 600.000 inhabitants, for a further improvement of the water quality ensured around a half stage. The purification plant cleans those beside the salt citizen waste water also of theSurrounding countryside and from the Bavarian Ainring.
bridges
beside the bridges in Salzburg exisitieren in the state capital also several pedestrian bars, transnational bridges over salt oh give it between the places running and upper village, between Tittmoning and Ostermiething and between castle living and oh. Many of these bridges were destroyed several times by floods. The flood of 13. August 1959 with 2.100 m ³ /s meant the end of the straight only delighted motorway bridge below Salzburg, which did not withstand the Wassermassen.
