Source (river or stream) in the context of "Montecoronaro"

Mount Fumaiolo (Italian: Monte Fumaiolo) is a mountain of the northern Apennines range of Italy located in the southernmost corner of the Emilia-Romagna region, c. 70 km from the town of Cesena. It's at the border between Emilia-Romagna and Tuscany. With an elevation of 1,407 metres (4,616 ft), Mount Fumaiolo overlooks the villages of Balze di Verghereto, Bagno di Romagna and Verghereto, in Romagna, and thanks to its extensive fir and beech forests, it is a well-appreciated tourist area of natural interest. It is most famous for being the source of the Tiber, as well as the river Savio.

The Segre (Catalan pronunciation: [ˈsɛɣɾə] or [ˈseɣɾe]; French: Sègre) is a river tributary to the Ebro (Ebre in Catalan) with a basin comprising territories across three states: France, Andorra, and Spain.

The river Segre, known to Romans and Greeks as Sicoris, and to the Arabs of Al-Andalus as Nahr az-Zaytūn (نهر الزيتون, river of Olives) has its sources on the north face of the Pic del Segre or Puigmal de Segre ("Segre's Peak") in the French department Pyrénées-Orientales (historically the comarca of Alta Cerdanya), in the Catalan Pyrenees. It follows a western direction all along the Cerdanya (Cerdagne) Valley, and crosses the town Saillagouse, the Spanish exclave Llívia, and Bourg-Madame.

The Savio is a river in the Emilia-Romagna region of northern Italy. Its source is in the province of Forlì-Cesena near Montecoronaro on Mount Castelvecchio which is near the western side of Mount Fumaiolo. The source is at an elevation of 1,126 metres (3,694 ft) and is marked by an iron monument. A wolf (the symbol of Montecoronaro) and the rings of the caveja (a symbol of Romagna) are on this monument. The river flows near Verghereto and Bagno di Romagna as it winds through the mountains before entering Lago di Quarto. After leaving the lake, the river flows northeast near Sarsina (near the border with the province of Pesaro and Urbino) and Mercato Saraceno before flowing north. The river winds for 96 kilometres (60 mi) along the valley. Its natural track has been preserved relatively well and, in the territory of Cesena, it shows an environment which is one of the purest of the whole Romagna. North of Cesena, the river crosses the border into the province of Ravenna. After a total course of 126 kilometres (78 mi) the river enters the Adriatic Sea north of Cervia by Lido di Classe and Lido di Savio.

The River Savio Natural Park, 6-kilometre (3.7 mi) along around a loop which once hosted a cave, starts from the two historical bridges of Cesena.

Horton Plains National Park (Sinhala: හෝර්ටන් තැන්න ජාතික උද්‍යානය, romanized: Hortan Thanna Jathika Udyanaya) is a national park in the central highlands of Sri Lanka that was designated in 1988. It encompasses an area of 31 km (12 sq mi) and borders Thotupalakanda Nature Reserve. It is located at an elevation of 2,100–2,300 m (6,900–7,500 ft) and encompasses montane grassland and cloud forest. It is rich in biodiversity and many species found here are endemic to the region.

The Horton Plains are the headwaters of three major Sri Lankan rivers, the Mahaweli, Kelani, and Walawe rivers. In Sinhala the plains are known as Maha Eliya Plains (මහ එළිය තැන්න). Stone tools dating back to Balangoda culture have been found here. The plains' vegetation is grasslands interspersed with montane forest and includes many endemic woody plants. Large herds of Sri Lankan sambar deer feature as typical mammals and the park is also an Important Bird Area with many species not only endemic to Sri Lanka but restricted to the Horton Plains. Forest dieback is one of the major threats to the park and some studies suggest that it is caused by a natural phenomenon.

The Bou Regreg (Arabic: أبو رقراق) is a river located in western Morocco which discharges into the Atlantic Ocean between the cities of Rabat and Salé. The estuary of this river is termed Wadi Sala.

The river is 240 kilometres long, with a tidal estuary of approximately 24 kilometres extending upriver. Its average discharge is 23 m/s and can reach 1500 m/s during periods of flooding. The source of the river originates from the Middle Atlas mountains at an altitude of 1627 meters on the level of Jbel Mtourzgane (province of Khemisset) and of Grou (province of Khénifra) and descends to its mouth at the Atlantic Ocean separating the cities of Rabat to the south and Salé to the north.

Headward erosion is erosion at the origin of a stream channel, which causes the origin to move back away from the direction of the stream flow, lengthening the stream channel. It can also refer to the widening of a canyon by erosion along its very top edge, when sheets of water first enter the canyon from a more roughly planar surface above it, such as at Canyonlands National Park in Utah. When sheets of water on a roughly planar surface first enter a depression in it, this erodes the top edge of the depression. The stream is forced to grow longer at the very top of the stream, which moves its origin back, or causes the canyon formed by the stream to grow wider as the process repeats. Widening of the canyon by erosion inside the canyon, below the canyon side top edge, or origin or the stream, such as erosion caused by the streamflow inside it, is not called headward erosion.

Headward erosion is a fluvial process of erosion that lengthens a stream, a valley or a gully at its head and also enlarges its drainage basin. The stream erodes away at the rock and soil at its headwaters in the opposite direction that it flows. Once a stream has begun to cut back, the erosion is sped up by the steep gradient the water is flowing down. As water erodes a path from its headwaters to its mouth at a standing body of water, it tries to cut an ever-shallower path. This leads to increased erosion at the steepest parts, which is headward erosion. If this continues long enough, it can cause a stream to break through into a neighboring watershed and capture drainage that previously flowed to another stream.

Barania Góra (Polish for "Ram Mountain") (German: Widderberg; Silesian: Baraniŏ Gōra) is a mountain in southern Poland. At a height of 1,220 metres (4,000 ft), it is the second highest mountain in the Silesian Beskids.

The sources of the Vistula, the longest Polish river, are located on the western slope of the mountain.

The Carhuasanta is a small river located in the Arequipa Region of Peru. It is known as the headwaters of the Amazon River. The brook is fed by the winter snows of Nevado Mismi, (5,597 m), some 6,400 kilometers from the Atlantic Ocean. Of all the possible river sources in the Amazon Basin, it is the snow melt of the Carhuasanta that has been calculated by cartographers to be one of the furthermost water sources from the mouth of the Amazon.

The Carhuasanta joins with the Quebrada Apacheta, becoming the Rio Lloqueta. The river has several more name changes before it becomes the Apurímac River. The mining town of Caylloma lies near the junction of four rivers that form the Apurímac river.
