NEW TECHNIQUES OF EROSION CONTROLS ON HILL ROADS

INTRODUCTION

Transportation contributes all round development of a country and hence plays a vital rate towards its progress. If the highways are not properly located and may contribute sediments to streams. The control of soil and water is basic to the protection of the road structure and therefore highway design, construction and maintenance must be continually evaluated to minimize erosion and sedimentation problems


MECHANISM OF SURFACE EROSION

Rain drops hit the slope surface
Impact of raindrop detaches the particle of soil

The runoff water flowing on slope surface transports the detached particle and may also contribute to further detachment


TYPES OF EROSION

WIND EROSION


RAIN EROSION



Wind Errosion

Exposed slope of non-cohesive loose and dry soil
Lack of shelter from wind
Exposed surface with out any protection




FACTORS CONTROLLING WIND EROSION

Wind velocity

Particle size of the material exposed to wind

Moisture content of soil

Vegetative cover


RAIN EROSION

Rain erosion is phenomenon of transporting of soil particle due to water action, the influencing factors for rain water erosion are
Potential of flowing water for initiating particle detachment
Physical features ie topography, gradient, embankment slope etc

Soil erodibility governed by clay content, particle size distribution, compaction , permeability, shear strength parameters etc of the soil


OBJECTIVES OF EROSION CONTROL

To prevent damage to land adjacent to the road structure
To reduce the soil loss from the land width of road, which silts up drainage channel and pollute rivers
To contribute to the improvement of the aesthetics of the landscape
To protect and preserve the earth work of fill or cut slope, ditches and drainage structure


EROSION CONTROL SYSTEM

TRADITION/ CONVENTIONAL METHODS
Agronomic method
Non-agronomic method
NEW TECHNIQUES “ENGINEER INOVATION
Reinforced vegetation
Coir geotextiles


AGRONOMIC METHOD

Simple vegetative trufing


Mulching of slope


COIR GEOTEXTIL

Made from coconut fiber extracted from the husk of the coconut fruit

It is a biodegradable organic fibre material containing cellulose and lignin

It gives max protection to the soil ES


SOME NEW TRENDS

SILT FENCE
CURLEX QUICK GRASS
STEEL GROUND STAPLES
DE WITT PROSPUN LANDSCAPE FABRIC
POLYPROPYLENE SAND BAGS


CONCLUSION

In all new construction erosion levels should be assessed in advance and appropriate protection measures are incorpoated in design.
In case of existing structures facing erosion problems, both short term and long term measures should be considered to ensure stability. For overall economy use of locally available materials should be the first choice. In extreme climatic conditions polymeric grids with root reinforcing mechanism may be used even though they are costly
