Guest Editorial Special Issue: Hydraulic Engineering Slovenian Association for Hydraulic Research (SDHR) is a voluntary-based association to promote and encourage professional and scientific hydraulic research work in the field of Civil, Mechanical and Environmental Engineering. It was founded in 1994 and has 89 active members. Its main aims are: to educate association’s members in the field of hydraulic research and accompanying research areas, to prepare and suggest changes of Hydraulic Engineering rules and standards and to organise professional meetings and excursions. As the association is public and open to useful suggestions, it has a good and fruitful collaboration with other professional organisations in the country and abroad. The most important among them are: Slovenian Committee on Large Dams - SLOCOLD, Water Management Association of Slovenia and International Association of Hydraulic Research - IAHR. One of the most important tasks of the association is also to publish professional achievements and news in domestic and international journals in order to present our work to other professionals and interested public. For that reason it was decided to select some lectures which have been given at SDHR’s meetings since 2004 and publish them in Strojniški vestnik - Journal of Mechanical Engineering. This is a reputable journal with an international exchange and it is indexed in a number of databases. The guest editors of this thematic issue wish to express our gratitude to the editor-in-chief of Strojniški vestnik - Journal of Mechanical Engineering, Prof. Vincenc Butala and to the technical editor of the journal Ms. Pika Škraba, who offered us all necessary professional, logistic and financial support. Papers based on the following five lectures were selected for publication: (1) Dynamic behaviour of air valves in a large-scale pipeline apparatus (2) Experimental analysis of the impact particles on the cavitating flow (3) Testing of concrete abrasion resistance in hydraulic structures on the lower Sava River (4) Two-dimensional mathematical modelling of a dam-break wave in a narrow steep stream (5) Application of an instrumented tracer in an abrasion mill for rock abrasion studies We would like to tank the reviewers for their concise and fruitful reviews.

Acknowledgement On grounds of financial cuts, the Publishing council of Strojniški vestnik – Journal of Mechanical Engineering (SV-JME) has abolished the position of Co-Editor in March 2012, thereby consensually relieving of duty the acting co-editor assoc. prof. dr. Borut Buchmeister. Dr. Borut Buchmeister was the co-editor from October 2009 and gave an important and permanent contribution to the increased reputation of SV-JME journal, evident from the quality of every issue. He was dedicated both to the journal and to the editorial board of SV-JME, always willing to provide assistance with his advice and work. We thank dr. Borut Buchmeister for his contribution to the development of SV-JME journal, wishing him a lot of success as the Editor-in-Chief of International Journal of Simulation Modelling.
