Their construction, maintenance and operation require major investments that burden the national economy in large measure. Construction costs of water management systems and facilities significantly depend on characteristics of the water regime, i.e. water regime is the determining factor for planning and implementation of water-related works and activities. Since the activities of planning and design of water facilities and systems often take place in areas with completely unknown or insufficiently known water regimes, the method of regional analysis is often used as the method to define and evaluate the parameters determining the water regime. This paper describes the conducted regional analysis of flood flows for the area of Bosnia and Herzegovina, which involves establishing regressio...

It is noticeable that values of parameters describing waste characteristics are approximately the same for similar areas. Still, every area has its particularity and therefore a waste disposal project should be based on real data measured in the observed area. Also, it is necessary to use data from literature which can help as a framework model for similar areas, which applies to the area of Herzegovina too. The karst area of Herzegovina has all preconditions to be an exceptionally desirable place for living and work. Therefore, problems arising from uncontrolled waste disposal must be addressed to without delay. This area is relatively well preserved with respect to underground water quality and water quality in general. However, if the increasing endangering of environment is not stopped at all levels, rehabilitation of the damage that may appear will be very difficult and at ...

It found a significant application in the process of defining the Geomorphologic Instantaneous Unit Hydrograph (GIUH) as the method aiming to relate geomorphological characteristics of a basin to basin response in the form of unit hydrograph, or direct runoff hydrograph. The paper analyzes the problems related to its implementation in the GIUH method, i.e. to determination of initial and transition probabilities, which, in turn, are used to define the probability distribution function for water flow paths in the basin. Many authors have agreed that this classification is rather rough and in some cases leads to certain irregularities, i.e. inaccuracies. The particular problem is that negative values may also result when calculating initial and transition probabilities at higher strea...

Za definiranje hidrograma, odnosno njegovog vrha (pika), uobičajeno se koriste statističke metode godišnjih ekstrema i pikova, za koje je nužno raspolagati povijesnim podacima o protoku, zatim empirijski izrazi, te hidrološki modeli. U radu je prikazana primjena hidrološkog modela EBA4SUB (Event-Based Approach for Small Ungauged Basins) namijenjenog za definiranje hidrograma otjecanja na neizučenim slivovima. Rezultati velikih voda rijeke Bistrice (pritoke rijeke Vrbas) dobiveni ovim modelom usporedit će se s razultatima empirijskih metoda. Kvalitet procijenjenih vrijednosti velikih voda dobivenih EBA4SUB modelom bit će provjerene na hidrološki izučenim profilima rijeke Vrbas, VS Gornji Vakuf i VS Daljan.

Flood wave propagation is calculated and flood maps are derived for different dam break scenarios. The methodology adopted for the development of the flood wave propagation model is based on the use of available tools for collection, processing and graphical display of geospatial data and tools for hydrodynamic modeling of transient flow. The selected approach is conservative and results are, as a rule, the worst case scenarios. Flood areas are obtained on the basis of hydraulic calculations with the most unfavorable assumptions: maximum water level in the reservoir, maximum inflow in the reservoir (with the return period of T = 10 000 years), instantaneous/gradual and total dam break, all of which result in extreme flooding.

Predložena metodologija omogucava cjelovito i sustavno rjesavanje problema, te djelotvorno ukljucivanje javnosti, transparentnost i demokraticnost postupka, ravnopravno tretiranje cijelog podrucja mogucih lokacija, racionalizira istražne radove, jasno prezentira utjecaje pojedinih rjesenja, i drugo. Rezultat je prijedlog lokacije koja predstavlja najbolje kompromisno rjesenje u skladu s kriterijima i preferencijama sudionika i javnosti.
