Two-Dimensional Numerical Analysis of Submerged Dike Hydrodynamics
Many studies have been conducted on wave and sediment movement with submerged dikes. However, the effect of a submerged dike’s height and orientation on hydrodynamics has not been thoroughly examined from the perspective of the marine ecology ...

Experimental investigation of flow pattern around repelling and attracting T-head spur dikes on flat bed [PDF]
, 2017 Use of T-head spur dikes is one of the common methods to control erosion of riverbanks. Nevertheless, setting spur dikes in the flow direction leads to modification of flow path and local scour in the site of the spur dike.

Flow resistance and associated backwater effect due to spur dikes in open channels [PDF]
, 2010 A spur dike is a hydraulic structure built on the bank of a river at some angle to the main flow direction. A series of spur dikes in a row may also be placed on one side or both sides of a river to form a spur dike field.

Influence of Spur Dike on Flow Patterns in an Open Channel [PDF]
, 2013 Spur dikes are used for river protection purposes. They are typical in-stream structures. There existence results in a considerable change in the flow structure of open channel flow both upstream and downstream of the spur dike.

Physical Fractional Step Method for Solution of 2D Water Flow around a Spur Dike
, 2011 A numerical model for simulating of 2D flow around a spur dike was presented by using the physical fractional-step method. The water governing equations were separated into three parts. The first is a convective problem; the second is a diffusive problem;

PIV analysis of flow structures around skewed spur dikes [PDF]
Spur dikes become to be recognized as hydraulic structures for environmental functions as well as for bank protection works. To predict and control flow, sediment transport and water quality exchange by using submerged spur-dike, it is necessary to ...
