Bradano in the context of Montescaglioso

The Gravina (also called Gravina di Picciano) is a river in the Apulia and Basilicata regions of southern Italy. Its source is near Poggiorsini and the border of the province of Barletta-Andria-Trani in the province of Bari. The river flows southeast near Gravina in Puglia before crossing into the province of Matera. It flows west of Matera before emptying into the Bradano as a left tributary a short distance after the Bradano exits Lago di San Giuliano.

The Peucetians were an Iapygian tribe which inhabited western and central Apulia in classical antiquity.

Two other Iapygian tribes, the Daunians and the Messapians, inhabited northern and southern Apulia respectively. All three tribes spoke the Messapian language, but had developed separate archaeological cultures by the seventh century BC; however, in Peucetian territory ancient Greek and Oscan language were spoken as well, as the legends of the currencies from Rubi and Azetium were trilingual. Peucetians lived in the eponymous region Peucetia, which was bordered by the Ofanto river and the Murge in the north, the Bradano river in the west and the territories of the Greek colony of Taras and the Messapians in the south. This region is mostly coincident with the Metropolitan City of Bari and parts of the provinces of Taranto and Barletta-Andria-Trani today.

Lago di San Giuliano is a lake in the Basilicata region of southern Italy. The lake is located entirely within the province of Matera. It is southwest of Matera, east of Grottole, and north of Miglionico. The Bradano flows into the lake from the northwest and flows out of the lake to the southeast.

Grassano is a town and comune in the province of Matera, in the southern Italian region of Basilicata. It is located between the Bradano and Basento rivers at an elevation ranging from about 150 to 576 metres (492 to 1,890 ft) above sea level. The town proper is 43 kilometres (27 mi) from Matera and 59 kilometres (37 mi) from the regional capital, Potenza.

The Alvo is a river in the Basilicata region of southern Italy. The source of the river is located in the province of Potenza between Pietragalla and Vaglio Basilicata. It flows north near Pietragalla and curves eastward north of Cancellara and south of the Bradano. The river then flows southeast near Oppido Lucano, Tolve, and San Chirico Nuovo before curving northeast. It then crosses the border into the province of Matera and joins the Bradano west of Irsina.

The Basentello is a river that flows near the border between the Apulia and Basilicata regions of southern Italy. Its source is near Palazzo San Gervasio. The river flows southeast and forms part of the border between the province of Potenza and the province of Barletta-Andria-Trani. It flows into the province of Potenza before entering Lago di Serra del Corvo. After flowing out of the lake, the river flows into the province of Matera near the border with the province of Bari. Finally, the river enters the Bradano as a left tributary shortly before the Bradano enters Lago di San Giuliano (a short distance before the Bilioso does the same).

The Bilioso is a river in the province of Matera in the Basilicata region of Italy. Its source is near Tricarico and San Chirico Nuovo and the border with the province of Potenza. The river flows southeast and curves northeast before again flowing southeast. It flows north of Grassano before entering the Bradano as a right tributary near Lago di San Giuliano (shortly after the Basentello does the same).

The Gravina di Matera is a river in the Apulia and Basilicata regions of southern Italy. Its source is between Altamura and Gravina in Puglia in the province of Bari.

The river forms the border between the province of Matera and the province of Taranto near Montescaglioso and Ginosa. Finally, it joins the Bradano as a left tributary in the province of Taranto.
