INTRODUCTION

For use of water assets, and protection from their harmful activities, it is neccesary to have knowledgeabout the water resources in concrete area .Each area faces the special problems of water. Theseproblems stem from existing wealths, seasonal oscillattions and developments in concrete area.Identification and selection of hydrological problems can best be realized within the rivers puddle. Oneof the problems is water regime, respectively the ways how they are supplied with water and yearlyoscillations. Knowledge of hydrological regime helps on solving the flooding problems,building andmaintenance of the rivers beds, land filed irrigation and water exploitation. The studing of concrete

puddle in general and the river in particular has a great practical and scientific significancel, becausethe hydrological data are the foundation for every kind of work related with the exploitation of therivers water as they are; the use of the water for industrial and municipal needs, construction ofartificial basins and lakes, anti-erosion meassures,rivers floods etc. The state of water ecomomy inKosovo is worsening each day.

HIDROGEOGRAPHYCAL CHARACTERISTICS OF BISTRICA PEJES RIVER

Bistrica e Pejes river has the second largest surface and water flux from Drini i Bardhe river (WhiteDrin). Ereniku river is the first. The surface of Bistrica e Pejes river is 500 km

2. It is 11.5% of total

surface of the Drini i Bardhe puddle and 13.7% of its stream. The Rugova Gorge is the result ofBistrica e Pejes river abrasive act. This is a 22 km long gorge. It is deep, narrow and hassteep

downards slopes andcliffy, especially at the bottom, where from around 6 km of its limestones flows anumerous different flux water streams and small waterfalls. The spring of Bistrica e Pejes river isespecially developed( upper part of the puddle) dictated by the Bjeshket e Nemuna, mountains withvery high sea level. In Bistrica e Pejes puddle there are also; caves, pond, circles and other forms ofglacial landscape as lakes, powerful creeks etc

HYDROLOGICAL REGIME

Knowledge about the hydrological regime helps in resolving the problems of flooding,river beds, landirrigation and water use. In this work are given general hydrological characteristics of Bistrica e Pejesas levels, flows, and hydrologic regime that is unexpedient.

Table 1. Minimum levels, and average monthly and annual Max (cm) for the River Bistrica PejaRugova's throat

The table indicates that the average annual level during 46 years period, has been 50.2 cm, while theminimum average level 0:43 cm and Max during this period was 192.3 cm Absolute minimum levelwas recorded on 12.09.2006 and had 0:30 worth cm, while Max apsolut on 19/11/1979 and has beenworth 350 cm.

Graph.1. monthly average levels of Bistrica Pejes (1963-2008)

From graph (1) we can notice that the highest levels appears during the spring months, when in themountains the snow begins to melt and when the level of rainfals is very high, whereas the minimumlevels usually can be noticed during August and September and start to increase again duringOctober when the Autumn rains begin. The monthly average of rainfall during this period of time inPeja has been 74.2 mm, average level 50.2 cm, monthly average flux 5.9 m3/sec average monthlywater temperature 6.6

0C. Bistrica e Pejes has unfavorable hydrological regime, because its largest

water flux is in the spring and autumn, therefore the possibilities for water accumulation and itsefficient use are much more limited.

CONCLUSION

The water of Bistrica e Pejes river is very qualitative, therefore in the past were drawn several draftprojects to build an acummulation in Drelaj habitation. Surrounding mountains give very favorableconditions for moutain tourism development. In recent years in Bogaj inhabitation has begun thewinter tourism development. Thanks to the contruction of skilift, hotel facilities, and road pavement the

number of tourists in this place in increasing year by year. In recent years in wonderful mountains inthis area has begun also the Camping tourism.
