Abstract

Soil erosion is a common challenge faced by geotechnical engineers, occurrings naturally in the environment due to wind, water, and gravity. The loss of soil from the land surface can be detrimental to both terrestrial and aquatic environments by depleting nutrients, increasing runoff and affecting aquatic life. Plenty of methods that can be used to control soil erosion. One of the common ways is using erosion control mat such as geotextile, turf reinforcement mats and fibromat biodegradable. The problems with the current mat are the manufacturer is focusing on the duration of the mat to decompose without considering the effectiveness to help vegetation grow. Through this research, the biodegradable erosion control mat was fabricated by using coconut coir as the main material (known as a coir mats) to promote the growth of vegetation roots, thereby reducing soil erosion. The research aim is to investigate the effectiveness of coir mats by monitoring vegetation roots growth whilst soil strength was evaluated by determining its shear strength, both with coir mat and without coir mat via Direct Shear Test. From visual observation, the results showed that the vegetation roots best developed in the soil covered with coir mat, where the fibrous of roots with coir mat is significantly uplifting compared to without coir mat. Besides that, the cohesion of soil for both with and without coir mat is 0 kN/m2 and it validated that the soils have the same water content during the test. However, the friction angle of the soil with coir mat is lower than without coir mat. This due to the smaller coir mat opening size, thereby affect the penetration and development of the vegetation.
