Drina

The source of Drina, looking downstream: the Tara entering the frame from the right, the Piva from the left, creating the Drina, in the middle of the frame and starts its flow towards a top of the image.

The Drina originates at the point of confluence of the rivers Tara and Piva, between the slopes of the Maglić, Hum and Pivska Planina mountains, and the villages of Šćepan Polje (in Montenegro) and Hum (Bosnia and Herzegovina). At its origin, it flows west, then makes a long curve to the northeast, around the Maluša mountain. From here it is northbound, in terms of general direction, for the rest of its journey toward the Sava. Here, in its headwaters, the Drina receives the Sutjeska river from the left.

The Drina is formed by the confluence of the Tara and the Piva rivers, both of which flow from Montenegro and converge on the border of Bosnia and Herzegovina, at Hum and Šćepan Polje villages. The total length of the Tara river is 144 km (89 mi), of which 104 km (65 mi) are in Montenegro, while the final 40 km (25 mi) are in Bosnia and Herzegovina along which form the border between the two countries in several places. The Drina flows through Bosnia and Herzegovina northward for 346 km (215 mi), of which 206 km (128 mi) is along the border of Bosnia and Herzegovina and Serbia, and finally spills out into the Sava river near Bosanska Rača village in northeastern Bosnia and Herzegovina. Measured from the source of the Tara, its longer headwater, the Drina is 487 kilometers (303 miles) long.

Major left tributaries: Sutjeska (at Kosman), Bjelava (at Trbušće), Bistrica (at Brod), Kolunska rijeka (at Ustikolina), Osanica (at Osanica), Prača (at Ustiprača), Žepa (at Slap), Drinjača (at Drinjača), Kamenica (at Đevanje), Sapna (at Karakaj) and Janja (at Janja).

Major right tributaries: Ćehotina (at Foča), Janjina (at Samobor), Lim (the longest one, 220 km, at Brodar), Rzav (at Višegrad), Kukal (at Đurevići), Rogačica (at Rogačica), Trešnjica (south of Ljubovija), Ljuboviđa (at Ljubovija), Jadar (at Straža) and Lešnica (at Lešnica).

Kayaking on the Drina.

The river is not navigable today, but together with the Tara it represents the main kayaking and rafting attraction in Bosnia and Herzegovina and Montenegro. However, during history, the small boats' traffic on the Drina was quite developed. Earliest written sources of the Drina boats date from the early 17th century. Traversing through this area in the second half of the 17th century, Ottoman traveler Evliya Çelebi noted that people in the Drina valley cut 40 m (130 ft) tall oak trees and use their trunks to make boats, by hollowing them with primitive tools and controlled fire. This type of boat is called monoxyl or dugout canoe. He writes that there were thousands of such boats at Zvornik, which navigated all the way to Belgrade, downstream the Drina and the Sava. Upstream from Zvornik, the boats didn't navigate.[2] Also, Foča has been the cradle of rafting, which was peculiar side-effect of the development of industrial forestry and increased forest exploitation in the 19th century. Local loggers are known to have transported downed trees downstream, from as far upstream as the Upper Tara river around Mojkovac in Montenegro, all the way downstream to the mills in Foča, by creating rafts from number of trunks and riding them navigating rapids and whitewater along the Tara canyon and Drina. rafts from explanation of local forests in Montenegro and Bosnia and Herzegovina since ancient times, known in the second half of the 19th century, when logs of felled forest, exploited by the Austro-Hungarians, were lowered along the Tara and Drina, all the way to the sawmill in Foča.

On its path northward to the Semberija region on the Bosnian side, and Mačva on the Serbian, both part of a wider area of Posavina, where it meats with the Sava, the Drina river passes through Podrinje and number of settlements situated within the region: Foča, Ustikolina, Goražde, Ustiprača, Međeđa, Višegrad, Perućac, Bratunac, Ljubovija, Zvornik and Mali Zvornik, Loznica.

The Drina flows between the mountains of Zvijezda and Sušica and it is flooded by the artificial Lake Perućac on the northern slopes of the Tara mountain, created by the Bajina Bašta power plant. The villages of Prohići and Osatica (in Bosnia and Herzegovina) are located on the lake, as well as the ruins of the medieval town of Đurđevac. The river is dammed at the village of Perućac, where a strong well springs out from the Tara mountain, flowing into the Drina as a waterfall. In addition, the waters of Drina are used for several fish ponds for the rainbow trout spawning.

The river continues to the villages of Peći, Dobrak, Skelani (in Bosnia and Herzegovina) and Zaguline (in Serbia), reaching the town of Bajina Bašta. At the villages of Donja Crvica and Rogačica, the Drina makes a large turn, completely changing its direction from the northeast to the northwest. This distinct geographical feature forms the Osat and Ludmer regions of Bosnia and Herzegovina, which are separated by the river from the Azbukovica part of the Podrinje region of Serbia.

From its point of origin, at Šćepan Polje (in Montenegro) and Hum (Bosnia and Herzegovina), the Drina, after initial a couple of hundred meters of running westward around the Maluša mountain, starts its northward general direction flow for the rest of its journey toward the Sava. Here it flows through the villages of Kosman, Prijedjel, Dučeli, Čelikovo Polje, Kopilovi, Trbušće, Brod na Drini, until it reach a town of Foča. In this section the Drina receiving waters of the rivers of Sutjeska, Bjelava and Bistrica, from the left, while in Foča it gets replenished with a significant amount of waters from the Ćehotina, which flows from the right.

Downstream from Foča, the Drina enters a wide valley, the 45 km (28 mi)-long Suhi Dol-Biserovina area between the southernmost slopes of the Jahorina mountains from the north and the Kovač mountains from the south. The villages of Zlatari, Jošanica, Ustikolina, Cvilin, Zebina Šuma, Osanica, Kolovarice, Vranići, Mravinjac, Biljin, Vitkovići and Zupčići are located in the valley, as well as the town of Goražde. The river receives the Kolunska rijeka and the Osanica as tributaries from the left.

The Drina continues in the northern general direction, flowing close to the villages of Žuželo, Odžak, Kopači and Ustiprača, entering the 26 km (16 mi) long Međeđa gorge, carved between the Vučevica mountains from the south and the southern slopes of the Devetak mountains from the north. The narrowest part of the Međeđa gorge is Tijesno, the 8 km (5.0 mi)-long section of the gorge where the river is at its narrowest (only 12 m (39 ft) wide), but also at its deepest (12 m). In this section it receives the Prača river from the left, and the Janjina and Lim rivers from the right. The villages of Trbosilje, Međeđa and Orahovci are located in the gorge, which is for the most part flooded by the artificial Višegrad lake, created by the Višegrad hydroelectric power plant.

At the town of Višegrad, the Drina receives the Rzav River from the right and turns northwest at the Suva Gora mountain into the Klotijevac gorge. The gorge is 38 km (24 mi) long and up to 1 km (3,200 ft) deep, carved between the mountains of Bokšanica (from the west) and Zvijezda (from the east). The villages of Sase, Resnik, Đurevići and Gornje Štitarevo lie in the gorge and the Kukal river flows into the Drina from the right. At the Slap village, the Drina receives the Žepa river from the right and turns sharply to the west, becoming a border river between Bosnia and Herzegovina and Serbia near the village of Jagoštica.

Flowing on the western slopes of the Bukovica mountain, the Drina passes next to the villages of Gvozdac, Okletac, Strmovo, Bačevci, Donje Košlje, Drlače, Vrhpolje, Donja Bukovica (in Serbia), Boljevići, Fakovići, Tegare, Sikirići and Voljevica (in Bosnia and Herzegovina), before it reaches the towns of Ljubovija in Serbia, the centre of the Azbukovica region (or Upper Podrinje from the Serbian side), and Bratunac, in Bosnia and Herzegovina, the center of the Ludmer region. Here the Drina receives the right tributary of Ljuboviđa and continues between the mountains of Jagodnja and Boranja (in Serbia), and Glogova (in Bosnia and Herzegovina). After the ruins of the medieval town of Mikuljak and the villages of Mičići, Uzovnica, Crnča, Voljevci (in Serbia), Krasanovići, Dubravice, Polom and Zelinje (in Bosnia and Herzegovina), the Drina is flooded again, this time by the artificial Zvornik Lake, created by damming for the exploitation by the Zvornik Hydroelectric Power Station. The villages of Amajic, Culine (in Serbia), Sopotnik, Drinjača and Djevanje (in Bosnia and Herzegovina) are located on the lake. This is also where the Drinjača river flows into the Drina (now the Zvornik lake) from the left, flowing from the Bosnian region of Gornji Birač.

After the dual town of Zvornik (Bosnia and Herzegovina)-Mali Zvornik (Serbia), the Drina flows between the Bosnian mountain of Majevica and the Serbian mountain of Gučevo, and enters the Lower Podrinje region. For the rest of its flow after the village of Kozluk, it has no major settlements on the Bosnian side (except for the town of Janja, which is several km away from the river, and some smaller settlements, like Branjevo and Glavičice). On the Serbian side, the Drina passes next to the villages of Brasina and Rečane, the ruins of the medieval town of Koviljkin grad, the spa and town of Banja Koviljača, the industrial town and center of the Podrinje region, Loznica, and its largest suburb, Lozničko Polje.

The Drina enters the confluence region of its course, the southern Pannonian plain, including the Serbian regions of Jadar (where it receives the Jadar river) and Iverak (where it receives the Lešnica). This is where the rivers spills in many arms and flows, creating the largest flood plain in former Yugoslavia, which the river divides in half. The east side, Mačva, is in Serbia, and the west side, Semberija, in Bosnia and Herzegovina (where it receives the Janja river). The Drina spills over and meanders, forming shallows, islands and sandbars, before emptying into the Sava river between the Serbian village of Crna Bara and the Bosnian Bosanska Rača. The variability of the water flow and low altitude resulted in several course changes during history. The Drina previously flowed into the Sava river near Šabac, 30 km (19 mi) to the east of the present mouth.

World Heritage-listed Mehmed Paša Sokolović Bridge in Višegrad, Bosnia and Herzegovina.

Commissioned by Grand Vizier Mehmed Paša Sokolović, the historic bridge, that today bears his name, the Mehmed Paša Sokolović Bridge, is constructed in Višegrad, in eastern Bosnia and Herzegovina, between 1571 and 1577. It was designed by the Ottoman court architect Mimar Sinan, and it's representative part of Bosnia and Herzegovina heritage, protected by the Commission to Preserve National Monuments of Bosnia and Herzegovina, and included into UNESCO's 2007 World Heritage List.

In September 2011, after local floods, an ancient boat was discovered, buried under the gravel in the Drina river, near Jelav, some 10 km (6.2 mi) north of Loznica. It is the first one in the Drina valley which was discovered in one piece and in such a good shape. The boat is 7.1 m (23 ft) long, 1.3 m (4 ft 3 in) wide and with the circumference of the back section of 4 m (13 ft). When dug out, it weighted 2 tons, but after drying out for two years in natural conditions, it was reduced to 1.3 tons. After being dried, it went through the conservation process in 2013. As the local museum in Loznica had no space to exhibit such a big item, a special annex was built especially for the monoxyl. It is estimated that it was made between 1740 and 1760 from the trunk of an oak that was 230 to 300 years old when cut. Based on the marks on it, this particular boat was most likely used for the transportation of the bulk cargo from one side of the river to another, as it seems to be too massive to be operated by the oars. Cuts and marks on it indicate that it was probably pulled over the river by the horses. It is possible that later, when it went out of service, it was used as the foundation of a watermill.[2]

During World War I, from September 8 to September 16, 1914, the Drina was the battlefield for battles between the Serbian and Austro-Hungarian army, the Battle of Cer and Battle of Drina. The Austro-Hungarians engaged in a significant offensive over the Drina river at the western Serbian border, resulting in numerous skirmishes and battles.
