Name

In antiquity, the river was known as Tibiscus (in Latin) and Tibisis (Θίβισις in ancient Greek), and as Timisis in De Administrando Imperio; in addition, Edward Gibbon referred to it as the Teyss.

The Romans, who traversed the plains of Hungary, suppose that they passed several navigable rivers, either in canoes or portable boats; but there is reason to suspect that the winding stream of the Teyss, or Tibiscus, might present itself in different places under different names.

Geography

The drainage area covers , of which in Romania. With the Danube, the Timis belongs to the Black Sea drainage basin. The river flows through Romania for , and through Serbia. Its average discharge at the mouth is .

The source of the river is near the mountain resort Semenic, in the Semenic Mountains, Caraș-Severin County, Romania. It flows towards the southeast, through the Trei Ape Reservoir, until it turns north near Teregova. Downstream from Caransebeș it turns northwest. It leaves the mountains and enters the Banat plain near Lugoj. After entering Banat, the river becomes slow and meandering. The most important port is the heavily industrialized Pančevo.

At the river's mouth, on the right bank, there is a forested area, the Pančevo Forest. It covers of marshland, with several dozen of deciduous species and 176 species of birds and mammals. The colonies of magnificent bryozoans were found in the river.

In June 2023, Serbian government began process of declaring a landscape of outstanding features Potamišje ("Tamiš valley"). It will protect the river's flood valley on the territory of Zrenjanin, Kovačica, and Opovo municipalities. A spatial plan for wider valley area (including Sečanj and Plandište) has been concurrently made.

Characteristics

Within the scopes of the Interreg IPA program, conducted jointly by Romania and Serbia, the area around the river has been arranged in the 2017-2019 period. Starting from Timiș' origin in Romania, up to its mouth in Serbia, the bird watch towers, benches, gazebos, small bridges, billboards, signposts and waste containers have been placed. The bicycle paths along the river have been built and locations for recreational fishing have been set. At Pančevo, near the confluence, there are catamarans, canoes and bicycles for renting.

By the 2020s, several beaches developed along the river's banks, outside if Pančevo. At Idvor, 250 poplars were planted, to restore the natural vegetation balance along the river. A small bridge was placed, and the crushed stone was poured before the beach, to purify and clear the water. In Glogonj, there is Skela beach. In Jabuka, there are two beaches. One, also called Skela, was arranged as part of the joint Serbian-Romanian project "Eco-Timiș - new touristic product". The other one is Pesak. All got new access roads, some of them have barges-restaurants, some sports fields, etc.

In its lower course, the river is regulated, and for the last it is navigable.

Pančevo had a busy port already in the 17th century, when it was occupied by the Ottoman Turks. Later, in Habsburg period, it became a hub of the river routes in the Banat region. The grain was transported to the capital Vienna, while later, with the industrialization of Pančevo, shipping of the beer, silk, salt, bricks and timber developed. In time, a row of halls, warehouses and storage object along the river bank were built. With the appearance of the steam power, the passenger transport developed too, connecting Pančevo and Serbian capital Belgrade. As Pančevo grew into the developed industrial center, by the early 20th century the traffic on Timiș became so intensive that the river had to be rerouted and straighten, with numerous canals being cut through around it.

Lighthouses

At the mouth of the Timiș into the Danube, there are two lighthouses, one on the each bank of the Timiș. They are one of the rare inland lighthouses in Europe, as the banks of the rivers are usually visible so there is no need for them. They are also among only few inland lighthouses in the world, and the only one in Europe, that were built in pair. Measured by the Danube, they are located at Danube'e , on its left bank, and from downtown Pančevo.

In some parts of the low, marshy areas created by the floods, several fish-filled lakes have been created, most notably at Banatski Despotovac, Uzdin, Sakule and Slatina.

After the Austrians officially took over the lands north of the Sava and Danube in the early 18th century, at the Timiș' mouth into the Danube, there was a derelict Ottoman stockade, surrounded by the palisades. In 1716 the Austrians began construction of the new, larger proper fortress, and finished it in 1720. It was a pentagon shaped structure built for artillery warfare., with brick-layered bastions, triangular ramparts, and a pontoon bridge across the Timiș. It resembled the Belgrade Fortress, and bailey of the Petrovaradin Fortress.

Settlement which developed within the fortress was the core of modern Panćevo. One of the stipulations of the 1739 Austrian-Ottoman Treaty of Belgrade was that Austria had to demolish all fortifications built in the previous two decades. Pančevo Fortress was razed to the ground, with nothing surviving above the ground level, but the settlement remained as a border town. Old downtown of Pančevo, and its street grid, were shaped by the size, position and orientation of the fortress. During the reconstruction of the City Park in 2013, remains of the foundations and brick walls of the southern rampart were discovered.
