In this paper, the morphometric characteristics of the Una River basin (Bosnia and Herzegovina) were analyzed using geographic information systems (GIS). Quantitative geomorphological analysis was carried out (hypsometric characteristics, slope inclination,vertical relief dissection, and slope exposition). Analyzed parameters are indicators of shapes and recent processes in relief. The significance of this analysis is reflected in the fact that the obtained data have numerical value, are verifiable and multiple applicable in practice for the purposes of agriculture water management, construction sector urbanism, tourism, spatial planning, etc.
U Bosni i Hercegovini nedostaje istraživanja na području valorizacije georaznolikosti, što je rezultiralo zanemarivanjem njezinih znanstvenih vrijednosti, ali i nedovoljnim razvojem geoturizma. Cilj je ovoga rada valorizirati odabrane geomorfolokalitete Parka prirode Blidinje s obzirom na njihovu geoturističku vrijednost. Primijenjeni metodološki koncept nastao je kao rezultat analize postojećih metodoloških koncepata valorizacije georaznolikosti, pri čemu su objedinjeni kriteriji za procjenu osnovne, dodane, zaštitne i turističke vrijednosti. Jedan od ciljeva rada jest i doprinos boljem razumijevanju i primjeni metodoloških koncepata turističke valorizacije, posebice u okviru zaštićenih prirodnih područja. Tijekom istraživanja izdvojena su 44 lokaliteta, a na osnovi rezultata preliminarne procjene kreirana je lista s ukupno 23 lokaliteta koji su valorizirani, od čega se njih osam izdvaja većom ocjenom od prosječne. Rezultati ovoga istraživanja upućuju na potencijal za razvoj ponude geoturizma PP Blidinje, čiji bi temelj trebali biti najbolje ocijenjeni geomorfolokaliteti.
Intensity of action and frequency of high and low pressure barometric fields of large and medium scale have great influence on dynamics of pluviometric regime. On their action depend characteristics of thermic regime, relative humidity, cloudiness and windiness, which directly affect the precipitation. Concerning that the water balance is difference between the inflow and evaporation, it comes that precipitations do not have just special role, but they are also the most important factor of the Una river regime. Disposition and precipitation structure are the river regime's essential assumptions, so at the same annual height of precipitation, we have more water in rivers in the year with more precipitations during the colder period. Then we have less evaporation so the inflow from the basin is bigger.
The amount and disposition of the precipitation in the Una River basin is analyzed in this paper in order to define the pluviometric regime of this area. Pluviometric regime greatly influences the Una river regime and water balance, what was the reason for this analysis and further hydrological research in the Una River basin.
V prispevku smo s pomočjo geografskih informacijskih sistemov (GIS-ov), kartografskih in matematično-statističnih metod analizirali morfometrične značilnosti porečja Une. Kvantitativna geomorfološka analiza je vključevala hipsometrične značilnosti, naklone, vertikalno razčlenjenost reliefa in ekspozicije reliefa v porečju Une. Analizirani parametri so indikatorji reliefnih oblik in sodobnih procesov preoblikovanja reliefa. Pridobljeni podatki imajo numerično in praktično vrednost, na primer za potrebe kmetijstva, upravljanja voda, gradbeništva, urbanizma, turizma, prostorskega načrtovanja itd.
