Zawodzie () is a part and a district of Katowice, located in the central-eastern section of the city, between Bogucice, Dąbrówka Mała, Janów-Nikiszowiec, Osiedle Paderewskiego-Muchowiec, and Śródmieście, along the Rawa river. The district is multifunctional, with a well-developed industrial sector (factories such as the and once operated there), including a rich tradition of metallurgy (the and Ferrum SA). Due to the presence of the University of Economics in the district, it also has a well-developed higher education sector.
The history of Zawodzie dates back to the late 17th century. It was founded as a colony of Bogucice on the other side of the Rawa river – "beyond the water" (za wodą in Polish) – which is said to be the origin of the district's name. Initially an agricultural settlement, it transformed into an industrial center in the 19th century. The main thoroughfare of Zawodzie's development became the present-day , along which a number of tenements, industrial plants, and public buildings were constructed, including the Gmina Bogucice Town Hall and the . Zawodzie belonged to Gmina Bogucice, which was incorporated into Katowice in 1924. In the 1970s, was built there, and a large portion of the district was redeveloped, resulting in the creation of a major transportation hub.
Several national roads run through Zawodzie: national road 79 ( and ) and national road 86 ( and Walenty Roździeński Avenue from the Bagienna interchange), as well as Warszawa Zachodnia–Katowice and railways, along which the is located. The district has an area of 4 km², and in 2020 had 10,835 inhabitants.
Geography Location Zawodzie is one of the 22 districts of Katowice, serving as a sub-unit of Gmina No. 3 and located within the group of eastern districts. The district is situated in the central-eastern part of the city and borders Bogucice and Dąbrówka Mała to the north, Szopienice-Burowiec to the east, Janów-Nikiszowiec to the south, and Osiedle Paderewskiego-Muchowiec to the west. Its boundaries are: to the north – along from the intersection with to the exit between buildings nos. 188 and 190; to the east – through industrial and commercial areas. South of these, the boundary runs along the west side of the Gigablok Wastewater Treatment Plant and follows the Rawa riverbed eastward. Further on, before intersecting with , the boundary runs south to Transportowców Street; to the south – the boundary runs between residential areas and the site of the former , and further on surrounds the from the east and south; to the west – the boundary runs north along to the railroad tracks, then turns west, running parallel to them, and at , it turns north, crosses Warszawska Street, and runs west from Jerzy Duda-Gracz Street to the tripoint with the boundaries of Bogucice and Śródmieście near the intersection with Walenty Roździeński Avenue.
The historical boundaries of Zawodzie run through the areas of two Katowice districts: Osiedle Paderewskiego-Muchowiec and Zawodzie. To the west, Zawodzie is historically bounded by Graniczna Street; to the north by the Rawa river; to the east, the boundary runs near the tram depot; and to the south, it runs through and the Valley of Three Ponds, crosses Murckowska Street, and continues behind the municipal cemetery and near the Amanda Colony. In terms of historical regions, the district is located in the eastern part of Upper Silesia.
According to physio-geographical regionalization, Zawodzie is located in the mesoregion, which forms the southern part of the Silesian Upland macroregion. The Silesian Upland itself is a part of the subprovince.
Geology Zawodzie is located in the in an area with horst structures. At the turn of the Devonian and Carboniferous periods, the Paleozoic bedrock of the Silesian Upland was disturbed by the formation of a sinkhole, which during the Carboniferous was filled with conglomerates, sandstones, and shales containing bituminous coal deposits. Formations from this period form the bedrock of the district, and a fault runs meridionally near Murckowska Street. Upper formations from the Carboniferous period cover a large part of the district, located south of the railroad tracks. Outcrops of the Orzesze layers (Westphalian B) are found there. They consist of massive sequences of mostly shale with intercalations of sandstone, siderite, and coal, and its thickness exceeds 900 m.
The main characteristics of the Zawodzie landscape were formed during the Tertiary period. At that time, intense chemical weathering and denudation were taking place. During the Quaternary, the area was likely covered by the Scandinavian ice sheet twice: during the oldest Mindel glaciation and during the Riss glaciation. The sediments from the first glaciation were mostly removed during the interglacial, while the Riss glaciation ice sheet left behind tills along valley depressions.
In Zawodzie, the area formed on till stretches along the valley of the south of the railroad tracks, while the urbanized part of the district along 1 Maja Street near and along is built on Pleistocene glacial and fluvioglacial sands and gravels. Additionally, the industrial and commercial areas on the border between Zawodzie and Bogucice are composed of sandy and silty eluvial till on layered sands.
During the current Holocene, Pleistocene sediment layers are being eroded and cleared away, while in river valleys a low terrace has formed in several stages. The valley of the Leśny Stream and the Rawa river in its immediate vicinity are composed of Holocene river sediments.
Terrain Zawodzie is located in the Silesian Upland, on the Bytom-Katowice Plateau, which is part of the mesoregion. The topography of the district is varied. The urbanized part of Zawodzie consists of river valley floors with Pleistocene terraces; the area along the southern section of Murckowska Street comprises flat clay uplands, while the remaining area, encompassing industrial and forested lands south of the railroad tracks, consists of hilly uplands.
The present-day topography of Zawodzie was mainly shaped by the Mindel glaciation and the maximum stage of the Riss glaciation, while in recent times, morphogenetic activity of humans related to settlement and mining has also had a significant impact. This has led to the destruction of the natural substrate and the creation of new forms of landform degradation. Almost the entire area of the district also forms an anthropogenic leveled surface.
In terms of morphological units, Zawodzie is located mainly in two areas. The urbanized part of the district is situated in the Rawa Depression. It is a valley form deeply incised into Carboniferous strata. The higher part of the terrace constitutes an erosional-denudational surface formed after the Riss glaciation. The Murcek Plateau, meanwhile, covers the southern part of the district, forming several distinct ridges as it extends toward the city center. Zawodzie's highest point is also located there, on the border between Zawodzie and Janów-Nikiszowiec, on the slope of hill. Its elevation is approximately 290 m above sea level. The lowest point is a large area in the eastern part of the district, in the Rawa Depression, with an elevation of less than 260 m above sea level. The elevation difference between the highest and lowest points is approximately 30 meters.
Soils The soils in Zawodzie have generally developed on a subsoil of sandy loam, while river valleys often contain an organic subsoil. Human activity has altered soil properties, and long-term urban development has led to the formation of anthrosols in the district. Some of the land is affected by mining operations and is also contaminated with heavy metals. The area along the Leśny Stream valley is covered with brown soils formed from tills and loamy and silty sands. Their properties are similar to those of brown soils, and their pH is mostly acidic or close to neutral. In the eastern part of the district, however, anthrosols formed from sandstones predominate. Human activity is the main soil-forming factor in these soils.
Surface and groundwater
Zawodzie is located within the Vistula drainage basin, in the basin of two rivers: and the Rawa. The Rawa basin covers the western, northern, and eastern parts of Zawodzie, while the Leśny Stream basin encompasses a section in the center of Zawodzie at its confluence with the Rawa and extends southward near Murckowska Street. A fifth-order drainage divide runs between the two basins.
The Leśny Stream is subject to ongoing regulation. In 2012, the water quality of the Leśny Stream at its confluence with the Rawa was assessed as poor, its physicochemical status was below good, its ecological potential and biological status were rated as moderate, and its status regarding the presence of particularly harmful substances was good at that time. The Rawa is an open drainage channel, fed mainly by rainwater as well as municipal and industrial wastewater. This river, a tributary of the Czarna Przemsza, flows from west to east within Zawodzie. Its entire course is regulated, and it is embanked. In 1913, as part of the regulation of the Rawa, the weir located near Zawodzie was removed.
Today, there are no bodies of water within Zawodzie, although the Kaszyca Pond was located on the site of the Zawodzie tram depot. It was visible on maps from 1916 and 1958. Between approximately 1916 and 1934, a pumping station was located there.
According to Bronisław Paczyński's classification, Zawodzie is located within the Silesian-Kraków hydrogeological region, in the Upper Silesian subregion. Aquifers are present in all strata, but their significance depends on several factors. According to Poland's division into Groundwater Bodies, the entire district lies within Groundwater Body No. 111 (Central Vistula Upland Subregion).
Climate The climatic conditions in Zawodzie are similar to those of Katowice as a whole. They are modified by both climatic and local factors. The district's climate is influenced more by oceanic factors than by continental ones, and occasionally by tropical air masses reaching the area from the southwest through the Moravian Gate.
The average annual temperature for the 1961–2005 period at the nearby station in Muchowiec was 8.1°C. The warmest month during the study period was July (17.8°C), and the coldest was January (−2.2°C). The average annual sunshine duration from 1966 to 2005 was 1,474 hours, while the average cloud cover during the same period was 5.3. The average annual total precipitation for the period 1951–2005 was 713.8 mm. The average duration of snow cover is 60–70 days, and the growing season lasts an average of 200–220 days. Throughout the year, westerly and southwesterly winds predominate (20.7% and 20.4% of all winds, respectively), while winds from the north are the least frequent (5.7%). The average wind speed was 2.4 m/s.
The climate of Zawodzie is influenced by local factors (microclimate), which depend on land cover as well as on the area's location relative to river valleys. The microclimate of areas located directly along the Rawa river is the most unfavorable. Heat is frequently radiated there, and high humidity causes evaporation to increase significantly, which absorbs heat. In areas of dense development, the local climate is influenced by the heating of the atmosphere due to human activity. Compact areas of buildings, roads, and squares cause an increase in air temperature in the lower atmospheric layer. These areas also lose heat more quickly due to radiation at night, and the lack of moisture in the air does not promote prolonged heat retention.
