Comparison of different drought assessment methods in continental Croatia

Susa je ekstremna hidroloska pojava koja izaziva velike gospodarske i ekoloske stete. Identifikacija i kvantifikacija suse provodi se primjenom razlicitih metoda. Za podrucje kontinentalne Hrvatske, na 15 meteoroloskih postaja od 1981. do 2011. godine, provedena je analiza 5 metoda za identifikaciju suse: indeks standardiziranih oborina, metoda decila, postotak od normale, indeks anomalije oborina i metoda koraka. Rezultati su pokazali da svaka od metoda ima svoje specificnosti, ali su sve primjenjive za analizirano podrucje. Indeks standardiziranih oborina ima znacajnu korelaciju s metodom decila, postotkom od normale i indeksom anomalije oborina. Prema vecini metoda najsusnije su bile 2000. i 2011. godine.Suša je ekstremna hidrološka pojava koja izaziva velike gospodarske i ekološke štete.

Variability of Hydrological Parameters and Water Balance Components in Small Catchment in Croatia

Analysis of small catchment area in Croatian lowland with its hydrological characteristics in the period between 1981 and 2014 was carried out in order to define significance of change in hydrological and meteorological parameters (precipitation, air temperatures, and discharges) and water balance components (deep percolation and potential evapotranspiration). There was no significant land use change in the observed period, so all changes in hydrological processes can be considered to be without human impact in the last 35 years. Application of RAPS (Rescaled Adjusted Partial Sums) on all data series distinguished two subperiods with different length but the same behaviour. The first subperiod was a period characterised by the decrease, starting in 1980 and finishing between 1991 and 1995, while the second one was a period characterised by the increase of parameters in all analyses, starting between 1991 and 1995 and finishing in 2001. In comparison to the analysis of climate change impacts per decade, this approach is much more appropriate and gives insight into variations throughout the entire observed period. The most variable but not significant parameters are precipitation and discharges, especially in the second subperiod which has a major impact on occurrence of hydrological hazards such as droughts and floods and makes great pressure and responsibility on water management system.

FLOOD MODELING OF THE VUKA RIVER SECTION UPSTREAM OF ITS CONFLUENCE WITH THE DANUBE RIVER

In this paper, a section of the Vuka River from its confluence with the Danube River in Vukovar to 3 + 630 rkm was modeled. The possibility and size o

Waste management in the Osijek-Baranja County

This paper gives an example of a potential waste management centre construction in the Osijek-Baranja County. First, the existing situation regarding waste management was established (quantity and composition). Today, waste is disposed on 9 ‘official’ landfills and a series of ‘unofficial’ ones. Considering the unsustainable nature of the present condition, which is contrary to the applicable Croatian regulations, efforts have been made to develop a solution with the aim of building a single waste management centre. The projections regarding mobility, generation, collection and disposal of waste for a period of 30 years are provided.
