Gaula may refer to:
Gaula flows through the Gauldal valley in Sør-Trøndelag county, Norway. It is the biggest river in Central Norway. The river begins in Holtålen near the mountain Kjølifjellet. It then flows through the municipalities of Holtålen, Midtre Gauldal, and Melhus before emptying into the Trondheimsfjord near Leinstrand on the border between Trondheim and Melhus.
The Gaula River is approximately 145 kilometres (90 mi) long and it drains a watershed of 3,661 square kilometres (1,414 sq mi). On its way it is joined by one large tributary, the Sokna River in the village of Støren in Midtre Gauldal. Other smaller tributaries include the Rugla, Hesja, Holda, Forda and Bua.
Within the Gaula River, there are two well known waterfalls called Gaulfoss close to the village of Hovin and the Eggafoss near the village of Haltdalen.
In 2005 the Gaula became the best salmon fishing river in Norway with a catch of 37.5 tonnes (36.9 long tons; 41.3 short tons) and 42.5 tonnes (41.8 long tons; 46.8 short tons) in 2008. However, the Gaula is constantly listed among the top 5 salmon fishing rivers in Norway.
Gaula is a Portuguese civil parish, in the municipality of Santa Cruz in the island of Madeira. The population in 2011 was 4,028, in an area of 6.95 km². It is located 7 kilometres (7,000 m) northeast of the island capital of Funchal.
Gaula's history is tied to universe of local history, popular culture, literature, traditions and customs; it was originally referred to as the terra do amadis de Gaula (Land of Amadis de Gaula), terra de adelos” (Land of the wandering salesmen), terras de doutores (Lands of the Doctors), terra de padres (Land of Priests), terra das amoras (Land of the Blackberries) and terras de malvasias (Land of the Malvasia), among others, that served to identify it from other regions of the island.
Many of these names arose of tradition and legend, when Gaulês were interrogated about the birthplace, they would respond with merry comments, such as I am from Gaula, what do you have with that, or outside the blackberry harvest, I am from Gaul for my sins. The oldest documented references referring to Gaula extend to 1509, when King Manuel I conceded this location the right to construct a small chapel to Santa Maria da Luz. Its toponymy was influenced by chivalrous romnances of the medieval era, namely, the historical romanance Amadis de Gaula from the 14th century.
