Also called groynes, spur, dikes, or transverse dikes. They constitute probably the most widely used training work. Spurs are the structures constructed on the river bank normal to the dominant flow direction or at an angle pointing upstream or downstream. A spur consists of a shank and a nose or head . These are widely used for the purpose of river training and serve one or more of the following functions: Training the river along a desired course by attracting, deflecting (or repelling) and holding the flow in a channel
Groynes or Spurs: It is a structure that is constructed transverse to the flow of the river. It extends from the bank into the river. Guide Banks or bonds: These are earthen embankments to channelize the floodwaters of the river. In India, this type of bond was first designed by Bell, hence it is known as bell's bond ADVERTISEMENTS: Read this article to learn about the most important types of river training works, i.e., (1) Embankments, (2) Guide Banks or Bell Bunds, (3) Spurs or Groynes, (4) Impermeable Groynes, (5) Permeable Groynes, (6) Bed Pitching and Bank Revetment, and (7) Dredging of River. 1.

Groynes or spurs: Structures constructed transverse to the river flow extending from the bank into the river. Can be aligned either perpendicular to the bank or at an angle pointing d/s or u/s. Also known as spur dike or transverse dikes and constitute the most widely used river training works Marginal bunds are also called as 'Spurs'. Embankment type structures constructed transverse to river flood, extending from the banks into the river (also transverse dykes) Protect the bank from which they are extended by deflecting the current away from the bank. Let us know in the comments what you think about the concepts in this article Each groyne can protect only a certain length and so the primary factor governing the spacing between adjacent groynes is their lengths. Generally, a spacing of 2 to 2.5 times the length of groynes at convex banks and equal to the length at concave banks is adopted. Groynes or spurs are classified as

Commonly used methods are by vegetation, sacks and blocks, gabions ripraps, guide banks, groynes etc. Groynes or spurs are structures constructed perpendicular to the rivers to protect the shore. Groynes may either be impermeable or permeable. Groynes deflect the flow from the shore and protect the shore. It has to be taken care that the groynes D. Groynes or Spurs: Groynes or spurs are constructed transverse to the river flow extending from the bank into the river. This form of river training works perform one or more functions such as training the river along the desired course to reduce the concentration of flow at the point of attack, creating a slack.
. Embankment type structures constructed transverse to river flood, extending from the banks into the river (also transverse dykes) Protect the bank from which they are extended by deflecting the current away from the bank The Principal objective of the study is to find out the impact of non-submerged groynes or spurs on downstream channel morphology of a moderately sand-bedded river of Dwarkeswar and how far it is responsible for channel degradation. 2.

Commonly used methods are by vegetation, sacks and blocks, gabions ripraps, guide banks, groynes etc. Groynes or spurs are structures constructed perpendicular to the rivers to protect the shore. Groynes may either be impermeable or permeable. Groynes deflect the flow from the shore and protect the shore Named after the large concrete blocks that jut out into the Otukaikino Creek, The Groynes is a recreational area just north of central Christchurch, with the creek as its central feature. Cut off from the Waimakariri River during work in the 1930s, the creek now forms several lakes and waterways through The Groynes
Groynes & Spurs . These are a hydraulic structure constructed transeverse to the direction of river flow and extend from the bank of the river to the width of river upto a certain limit. These are also called spurs. Groynes are suitable in guiding the river flow,promoting scour, depositing of sediment where desired and traping the sediment load. Groynes ( spurs ) are structures constructed transverse to the river flow and extend from the bank into the river. These are widely used for river training and bank protection. This standard was first published in 1976 under the title 'Criteria for river traming works for barrages and weirs in alluvium'. Now, since different river training. (c) Groynes or Spurs They are the embankment type structures, constructed transverse to the river flow, extending from the bank into the river They are constructed to protect the bank from which they are extended, by deflecting the current away from the bank It protects the bank for certain distance upstream and downstream of the groyne
Spurs are structures that protrude into the river. Small spurs know as studs help keep the flood water away from venerable banks. Long spurs, also referred to as groynes, are used to direct the course of the river away from a vulnerable bank. The spurs make permanent changes to the rivers course by capturing sediment Spurs (also known as spur dikes, groynes or transverse dikes) are generally made of locally available earth material in the form of an embankment constructed transverse to the flow extending from one of the river banks into the river. Spurs are the most widely used river training structures, and serve the following functions in river regulation Groynes or spurs are usually earthen embankments constructed transverse to the river flow deflecting the current away from the bank. Thus river banks are protected from erosion due to excessive currents. There are several barrages in Bangladesh. The notable ones are-Tista Barrage, Buri Tista Barrage, Tangon Barrage, Monu Barrage.. Start studying River Clyde and Dorset Coast case study geography. Learn vocabulary, terms, and more with flashcards, games, and other study tools (c) Spurs or groynes (a) Guide Bank. When a barrage is constructed across a river that flows through the alluvial soil, the guide banks must be constructed on both the approaches to protect the structure from erosion. Guide bank serves the following purposes: It protects the barrage from the effect of scouring and erosion

An example outlining recommended procedure for establishing the geometric layout of spurs within a spur scheme is recommended Groynes The function of groynes is similar to that of spur. But these are impervious permanent structures constructed on the curve of a river to protect the river bank from erosion. They extend from the bank towards the bed oby making an angle of 60 to 75o with the bank. The angle may be towards the upstream or downstream. Sometimes, it i 8) Groynes or spurs A spur, spur dyke, or groyne is a structure made to project flow from a riverbank into a stream or river with the aims of deflecting the flow away from the side of the river on which the groyne is built. Hence in this way you can design a guide bank. So, I hope this article on river training works remains helpful for you For instance, groynes or spurs pointing downstream attract flows to the river bank rather than deflecting them away from the bank. Truly deflecting or repelling groynes have an upstream inclination. Another example is that the heaviest fluvial attack on training structures mostly occurs around bankfull conditions rather than flood conditions.
Spur is a permeable and temporary structure. These structures are constructed on the curve of a river to protect the river bank from erosion. This type of structure is most suitable where the river carries sediment load in suspension. Don't be confused about spur and groynes, both are the same type of structure but the main difference is that. Under the plan, Rs348.2 million will be utilised to different projects of irrigation sector including 45 flood protection works in different parts of the district, 15 groynes or spurs. River training works include transverse structures (e.g., groynes, spur dikes, spurs), longitudinal structures (e.g., bank revetments, guide bunds) and structures on the river bed (e.g., ﬁxed layers, bendway weirs, checkdams). Experienced river engineers share some practical wisdom that is not immediately obvious to novices or laymen ACRONYMS: FEMD Flood Engineering and Management Division. HEC-RAS The Hydrologic Engineering Center, River Analysis System is a computer program that models the hydraulics of water flow through natural river
. These are temporary structures permeable in nature provided on the curve of a river protect the river bank from erosion. These are projected from the river bank towards the bed making angles 60-70 degree with the bank of the river. The length of the spurs depends on the width of the river and the sharpness of the curve Check out products related to Geography, Travel and the Outdoors on Amazon:https://www.amazon.com/shop/darrongedgesgeographychannel (Paid Link)This video out..

Groynes are one of the most widely used river training structures for prevention of bank erosion. They are often constructed in series to prevent vulnerable river banks. As they require a huge amount of investment cost, this study deals with determination of a cost-effective combination of groynes to exert control over a river reach. A linked. 1 Answer1. Active Oldest Votes. 3. Levees protect land that would normally be dry from flooding. Dikes protect land that would normally be under water from flooding. Dikes are most often associated with the sea and areas of land below sea level, Levees are most often associated with rivers. A berm is similar in structure but not used for flood.
Synonym for levee A levee protects land that is usually dry from being flooded. A dike protects land that would usually be covered by water.
