In this study, a relation-based dam suitability analysis (RDSA) technique is developed to identify the most suitable sites for dams. The methodology focused on a group of the most important parameters/indicators (stream order, terrain roughness index, slope, multiresolution valley bottom flatness index, closed depression, valley depth, and downslope gradient difference) and their relation to the dam wall and reservoir suitability. Quantitative assessment results in an elevation-area-capacity (EAC) curve substantiating the capacity determination of selected sites. The methodology also incorporates the estimation of soil erosion (SE) using the Revised Universal Soil Loss Equation (RUSLE) model and sediment yield at the selected dam sites. The RDSA technique identifies two suitable dam sites (A and B) with a maximum collective capacity of approximately 1202 million m3. The RDSA technique was validated with the existing dam, Gomal-Zam, in the north of Sanghar catchment, where RDSA classified the Gomal-Zam Dam in a very high suitability class. The SE estimates show an average of 75 t-ha−1y−1 of soil loss occurs in the study area. The result shows approximately 298,073 and 318,000 tons of annual average sediment yield (SY) will feed the dam A and B respectively. The SE-based sediment yield substantiates the approximate life of Dam-A and Dam-B to be 87 and 90 years, respectively. The approach is dynamic and can be applied for any other location globally for dam site selection and SE estimation.

According to the models which are commonly used in practice, the capacity of roundabouts depends on the value of critical headway. Critical headway size depends on numerous objective factors, primarily on geometric characteristics of the intersection. However, research so far have shown that beside characteristics of the intersection, value of critical headway depends on many other factors, primarily on driver behavior. Driver behavior is the result of the action of numerous factors that depend on the influence of local environment, habits, mentality, etc. For that very reason, determination of the value of this traffic flow parameter in local research is recommended in many models. Within this paper, the results related to the value of critical headway determined by research which are conducted in Bosnia and Herzegovina are presented. The presented value of critical headway can be used for objective determination of roundabout capacity in our region.

Th e new Law on Compulsory Traffi c Insurance has recently entered into force in the Federation of Bosnia and Herzegovina. By enacting of this Law the high level of harmonization with EU-acquis has been achieved. Besides, the interstate harmonization, i.e. equalization with the same-named Law act in Republic of Srpska has also been achieved. Th e special characteristic of this Law that diff ers it from the similar acts in SEE region and wider, is regulating of the rules for determination of the scope of pecuniary and non-pecuniary damage occurred in a traffi c accident. Th e set of rules is prescribed in form of the Framework criteria for determining the compensation amount for injuries or death, which are an integral part of the Law. In this paperwork, the overview of the mentioned Framework criteria will be shown, as well as their importance with regards of legal certainty in determination of the scope of damage. Also, there is a discussion about overcoming the interstate confl ict of law that occurred by their enacting.
