A morphodynamic stability analysis of gravel beach cross-section by 1D numerical model

U radu je opisna analiza stabilnosti sljuncanih plaža i razvoj njihovog profila u poprecnom smjeru pri djelovanju gravitacijskih vjetrovnih valova. Analiza je provedena tehnikom numerickog modeliranja. Modelski pristup primijenjen je i u analizi valnih deformacija i morfodinamike na primjeru sljuncane plaže Medveja. Rezultantni modelski profili plaže koreliraju s izmjerenim poprecnim profilima plaže Medveja, pa se metodologija i dobivena procjena erozije materijala plaže mogu prakticno primijeniti pri donosenju odluka u raznim fazama projektiranja.

Volumetric analysis of flow through flushing culverts embedded in breakwaters

Water renewal in harbors and marinas largely depends on the availability of natural generators at a particular location, with tidal oscillations frequently being the most dominant one. In low tidal range areas, it is common to use flushing culverts in order to improve water renewal. Field measurements conducted in ACI marina Opatija point to a significant but brief increase in flow through the flushing culvert due to wind and waves. Considering the whole measuring period, seawater is predominately flowing through the culvert in the direction of the surrounding sea, which may be the result of freshwater sources present in the basin.

Analysis of vertical pressure load exerted on horizontal RC plates by wave impact

The analysis of dynamic pressure load exerted on the caisson structure bottom cover plate subjected to wave action is presented and illustrated by the example of Zagreb Pier in the Port of Rijeka. In addition to physical model measurements, empirical models are applied using input data from the linear wave theory and numerical model. The reliability of the applied methodology is assessed through comparison of measured and modelled values. The best correspondence between the measured and modelled results is obtained using the linear wave theory and the Kaplans (1995) empirical model.

Basic plan dimensions of marinas in Croatia

Radi unaprjeđenja urbanistickog i ekonomskog planiranja nautickog turizma u Hrvatskoj, u ovom je radu provedena analiza i prezentacija tlocrtnih parametara 39 postojecih hrvatskih marina. Prikupljeni tlocrtni parametri su: broj vezova, broj suhih vezova, duljina lukobrana, duljina fiksnih gatova, duljina pontona, duljina obala, povrsina akvatorija, povrsina teritorija, ukupna povrsina, povrsina suhog veza i povrsina parkiralista. U radu su prikazane ovisnosti navedenih parametara u funkciji broja vezova u moru te su definirani prosjecni statisticki pokazatelji navedenih parametara koji karakteriziraju gradnju marina u Hrvatskoj.
