25 Aug 2016 The layout of training works for a barrage, weir or bridge are almost identical and consist of a pair of guide banks and armoured groynes. The guide banks are two heavily armoured embankments in the river in the from of a bellmouth figure. Simple approach embankments span the portion of the river
Instructional objectives: 1. The need for river training. 2. Guide bunds for restricting the flow path of river waterway. 3. Afflux bunds, approach embankments, groynes ,spurs, etc. for river waterway control. 4. The issue of riverbank failure and lateral migration of rivers. 5. Different modes of bank failure. 6. Techniques for bank

12 Nov 2017 Guide Bank are earthen embankments with stone pitching in the slopes facing water, to guide the river through the barrage, These river training works are provided for rivers flowing in planes, upstream and downstream of the hydraulic structures or bridges built on the river. Guide banks guide the river

(1)Guide banks • The works required in the river to guide the passage of river water through weir or barrages are called guide banks. • The guide banks consist of two heavily built set of embankments with heavily protected
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.
Guide banks: Earthen embankments => stone pitching. Force the river into restricted channel, to ensure almost axial flow near the weir site. (embankments in continuation of G-Banks. To contain flood within flood plains)
