ASSESSMENT OF WATER DEMANDS IN THE RURAL SETTLEMENTS
OF THE SOMEŞEAN PLATEAU

ABSTRACT. –Assessment of water demands in the rural
settlements of the Someşan Plateau. Through this paper we have evaluated four
different water demand calculations, which would allow the development of water
supply strategies on a short, medium and long term. Judging by the second
variant of calculation the total water needs of the localities, from the
Someşean Plateau, ranges from 40,9 l/s, for the first variant, to 199,4 l/s, in
case of the second variant. Water demand was estimated at administrative level
(district, commune and localities), for the main river basins and their related
sub-basins, and also on a geographical sub-units level. Regardless of the
variant we used when calculating the weight of units or analyzed subunits, this
remains the same. For example, the Cluj County holds 66.5% of the necessary
water in the Someşean Plateau, followed by the counties of Sălaj and Maramureş
with 28.8% and 5.7%. The river basins of Someş and Someşul Mic represent
approximately equal weights (48.3% and 48.6%), while the basin of Lăpuş is
defined by a very small percentage. The share that defines different
administrative subunits, either geographical or hydrographical, depends on the
area, density and size of the related localities. The share of water that
belongs to each geographic subunit from the Someşean Plateau ranges between
33.8% (in the Cluj Hills) and 6.3% (in the Sălătruc Hills). The water volumes
required annually by the Someşean Plateau localities oscillates between 1288 m3,
in the first case scenario and 6281 m3 in the fourth case. So, the evaluated
water volumes should be decreased, on average, by about 30%, depending on the
specific circumstances of the territories studied by taking into account the
unfavorable position of some towns to the main hydrographical course, the size
of settlements, as well as the opportunities of their future development.
