River‐Bend Bank Protection by Submerged Vanes

Journal of Hydraulic Engineering, 1983
It is shown, theoretically and by a physical model, that short, vertical, submerged vanes installed at incidence to the channel axis in the outer half of a river-bend channel significantly reduce the secondary currents and the attendant undermining and high-velocity attack of the outer bank. The effect of the vanes on the secondary flow is estimated by

River Bank Filtration for Protection of Jordanian Surface and Groundwater

World Environmental and Water Resources Congress 2010, 2010
Jordan is considered to be one of the 10 poorest countries worldwide in water resources, and has a population growth rate of about 2.9% (1998-2002), the 9th highest in the world. The available renewable water resources are dropping drastically to an annual per capita share of 160 m 3 in recent years.

Prediction of river bank erosion and protection works in a reach of Chenab River, Pakistan

Arabian Journal of Geosciences, 2018
The impacts of floods on river bank erosion are generally significant in the alluvial river reaches. This paper presents the prediction of the river bank erosion along the right bank in the reach of Chenab River (starting from downstream of Marala Barrage) where excessive erosion had been reported. The bank erosion is predicted due to flow/flood events

Geo-Jute for River Bank Protection - A Case Study

Journal of Agricultural Engineering (India)
Geo-jute is jute matting, which has been successfully developed by needle-punched non-woven and woven techniques and has been tried for erosion control and reinforcement of soil. Plant roots trap soil particles and prevent erosion. Non-woven & Woven Jute Geo-fabrics are widely used, as these are eco-friendly, economical, biodegradable, nontoxic ...

Protection of banks and roadbeds from erosion on river ?NIPS?

Hydrotechnical Construction, 1986
The developed recommendations make it possible: to determine the size of stone in the protective layer of bank slopes and groins; to determine the location of the upstream groin; to assign the main parameters of the groins; steepness of the slopes, length and angle of bend of the groins, distance between groins; to distinguish the region of the groin ...

Protection of Bank of River for Very High Discharge of Flow

2020
Simulation of discharge of flow and depth of flow for 0.75-inch roughness bed data is done and depth of flow for Qp = 15000 m3/sec. was found from the derived equation where Qp = Discharge of flow for prototype or river hydraulics. Similarly, simulation between depth of flow for depth of flow and maximum permissible velocity was done and the depth of ...

Construction and Performance of River Bank Erosion Protection Structure in the Niger Delta

Environmental & Engineering Geoscience, 1986
Various bank erosion control measures were examined for applicability in the Niger Delta. Anchored sand-filled polypropylene mattress revetment fulfilled the requirements of optimum performance and safety. The principal design considerations of the protection revetment are analyzed using geo-technical and hydrometric data.

Bed topography and local scour in rivers with banks protected by groynes

Journal of Hydraulic Research, 1995
This paper provides some results of field investigations of bed topography and local scour at groynes in two bends of the Warta River. Concave banks of these bends are protected by impermeable groynes oriented upstream with almost constant spacing and geometric shape. Both bed topography in bends and local scour holes at the groyne heads were formed by
