This paper presents a hydraulic analysis of unsteady flow due to a possible dam break of the Tribistovo reservoir located in the Municipality of Posušje, Bosnia and Herzegovina. 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.

A basic statistical data analysis and trend analysis were performed for the flows recorded at the Tisne Stine 1 gauging station on the Cetina River. The analysis was carried out using the linear and nonlinear regression, Mann-Kendall test, and the so-called RAPS method. [ABSTRACT FROM AUTHOR]

Problem of determining the hydrograph of high waters is one of the basic problems in hydrotechnical practice. To define the hydrograph and its peak, regular statistical methods of annual extremes and peaks are commonly used if historical flow data are available, if not, empirical expressions and hydrological models are used. The paper shows the use of a hydrological model EBA4SUB (Event-Based Approach for Small Ungauged Basins), designed to define runoff hydrograph from ungauged basins. Values of high waters of Bistrica river basin (tributary of river Vrbas) obtained with this model will be compared with the results of empirical methods. The quality of the estimated peak values of high waters obtained with the EBA4SUB model will be tested on hydrologically studied profiles of river Vrbas, WS Gornji Vakuf and WS Daljan.

The subject of this paper is to determine ecologically acceptable flow on the measurement profile Neretva - Zitomislici on the basis of flow measurement data from 1926 to 1954. The first part of the paper presents basic characteristics of the Neretva river basin and Rulebook on the method of determining ecologically acceptable flow. In the second part, ecologically acceptable flow was calculated according to the specified rulebook, specifically for the level I of evaluation, as well as according to the Water Act. The conclusion at the end presents a comparison of these two calculations. [ABSTRACT FROM AUTHOR]

Irrigation systems are designed and constructed in order to compensate the lack of water needed for optimal cultivation of agricultural crops caused by lack of precipitation and/or water storage in the soil. When selecting an area for irrigation, natural resources of the area are taken into account, i.e. soil and water, as well as possibility of integration into the present state, planning and detailed documentation and local interests of the area. The paper gives an overview of water needs of some agricultural crops based on analysis of climatic parameters of the area of Herzegovina-Neretva County. Next, it presents the methodology of production of maps of soil suitability for irrigation, and gives the results of analysis and maps of soil suitability for the area of HNC. [ABSTRACT FROM AUTHOR]
