Relief, climate and watercourses
Rîu de Mori is located in Hațeg Country in the southern part of Transylvania and in the southwestern part of Hunedoara County. This natural enclosure is defended as a shelter of the Retezat Mountains in the south, the Poiana Ruscă Mountains to the west and east of the Sebeș Mountains.
The area is studied and named in the Territory Planning Plan of Hunedoara County, the "southern area" and includes the Hațeg Depression, Retezat Mountains, Parâng and Șureanu.
The area has predominantly agro-forestry profile and tourism and hydro-energetic potential.
With numerous peaks over 2200 m heights, the Retezat Massif has the highest average altitude not only in the Southern Carpathians, of which it is part, but also from the entire Romanian Carpathian chain.
The most peaks of the massive peaks are: Peleaga (2509 m), Păpuşa (2500 m), Retezat (2482 m), Custura (2457 m), Bucura (2433 m), Slaveiu (2347 m), Vârful Mare (2346 m), Judele (2333 m), Valea Rea peak (2311 m), etc.
The name of the massif comes from the name of the peak Relezat, which, although not having the highest height, is still the most picturesque mountain, as a legend says, by a plow-iron thrown with great anger by one of the two giant brothers have once settled down the ground.
: The massif is limited to the north of Hațeg Depression, to the south Buta valley to the Plaiul Mic saddle and to Lăpușnicu Mare, to the east of the lower course of the Bărbat River and the talveg
of a brook left beneath the Fagettel currant, and to the west by Curmătura Făgeţelului the limit with the Țarcu Mountains.
Geology: The actual reticulation consists of crystalline and granodiorite shale and has higher heights than Retezatul Mic, which is made up of ironing.
The glacier relief occupies the largest expanse in the Retezat Mountains. The glacial circles and valleys along with the alpine ridges form the major patterns of this relief. The presence of frosts characteristic of the area is due to frosts and repeated frosts during the pleistocene period.
The karstic relief can be found in the Retezat Mic area, where speleological caves and interesting caves have been discovered and the climbers have at their disposal both here and Retezatul Mare many trails with piles.
Characteristic are dry valleys, valleys (on the Valea Svoabelor), avene (the Stâna Tomii - the second vertical in the country), the caves (Zeicu) and the lakes.
Massive Climate: The sub-alpine climate in the forests and pastures areas is characterized by a moderate thermal regime with monthly average monthly temperatures that fluctuate between 10 ° C in August and -10 ° C in February.
The annual rainfall in the Alpine area is between 800-1200 mm.
In the alpine area of the hedgerows and alpine meadows, the annual average temperature has negative values and the annual rainfall exceeds 1400 mm.
Hydrography: The Retezat has a dense network of flowing waters that have Gura Apei lake as destination.
The artificial lake Gura Apei, with rich and permanent flow, except the Piatra - Iorgovanu zone where, due to the limestone relief, the surface water circulation is intermittent. The most important water courses are:
- Râul Mare River formed at the confluence of the Lapușnicul Mare with the River Şes, Lăpuşnicul Mare formed by the union of the Peleaga parks with Bucura and enriched by some smaller tributaries (Draganu, Paltin, Berhina, Lăpuşnicu Mic, Slaveiu, Turcelu, Judele Mare, Custura Mică and Ciumfu Mare).
- U.P. I Râuşor includes entirely the basin of river Râuşor with drainage in the Râu Mare.
The main inhabitants of Râuşor River are: Putinciu, Strugaru, Sec Apa Şteviei Stream, Vălăreasa, Clina, Surpure. Also, with direct flow into the Râu Mare, there are the Ciurila and Diljii Valley, which are separate basins.
The high relight flow of the River determined the capture and the water flowing inside the reservoir of the hydroelectric basin Râu Mare.
