Experimental studies to investigate the depth of the scour conducted at a side-weir intersection located at the 180 curved flume which located Hydraulic Laboratory of Yıldız Technical University, Istanbul, Turkey. Side weirs were located at the middle of the straight part of the main channel. Three different lengths (25, 40 and 50 cm) and three different weir crest height (7, 10 and 12 cm) of t...

Bridges when it crossing rivers often required multiple piers for support. One of has a limited investigation is the impact on scouring and morphological aspects bridge sharp-bend river. Consequently, crucial to investigate hydraulic behavior water flow in these areas due presence piers. In present study, an experimental program was conducted laboratory flume featuring two-pier within 180-degre...

Bridge infrastructure assets should be planned, designed, constructed, and operated to account for the physical processes that may occur over their service lives. In ice-affected rivers, this includes interaction of bridge with river ice. Advancements in river-ice science modelling ice ice-covered rivers has enhanced abilities civil / hydrotechnical engineers plan, design, construct bridges alo...

This study addresses the design of riprap aprons as a scour countermeasure near abutments under clear-water conditions. It deals with the lateral extent of riprap aprons and the geometry of the scour hole prevailing at the apron edge. The study applies to riprap aprons acting as granular filters. The scour depth appears to be independent for a sufficiently long relative abutment length. Scour h...

Series of laboratory tests were carried out to study the extent of scour caused by a three-dimensional wall jets exiting from a square cross-section nozzle and into a non-cohesive sand beds. Previous observations have indicated that the effect of the tail water depth was significant for densimetric Froude number greater than ten. However, the present results indicate that the cut off value coul...
