To enhance slope stability, we need to understand the essence of geotextile. The application of geotextiles has proven to be useful in bioengineering. This is usually done to enhance and maintain the state of such biosystems. Specific types of cover crops could be used to control erosion, enhance soil fertility and protect soil nutrients. But without the presence of the appropriate geotextile, unforeseen geological hazards such as landslides, slope failures, debris flows and rockslides can occur, washing the preserved nutrients and destroying biodiversity. Several geotextile materials have been proposed and used in bioengineering, but there is still an unanswered question, as to which of the materials is appropriate for a given site.
Nsiah (2012), mimicked the BORASSUS project and used elephant grass as a biological geotextile material to stabilize slopes. The questions about his project are, why elephant grass? Was elephant grass the appropriate material to be used, given the site conditions? Can the results be improved if another material is used? Or was that the cheapest material available? This research seeks to find answers to these questions by undertaking a slope stability project using different possible geotextile materials. The ability of the materials used, to control erosion, stabilize slope and promote biodiversity will be determined statistically. This will help bring to light the appropriate geotextile material for a given site.

WELCOME TO THE SKILLS ARENA

It’s finally time to embrace the adorning of our first love (geotextiles). This stage brings us to the gathering and design of the geotextiles to stabilize the prepared slope. The activity took place on the 4th day of our first visit to the site. All hands on deck, the team set out into the scouted areas to gather the geotextiles. The palm fronds were the easiest to find within the environs of the quarry.

SITE PREPARATION

The slope on which the geotextiles will be applied for stability cannot be overemphasized. This is because, in other to determine the best geotextile, all geotextiles must be subjected to the same slope conditions so as not to be biased towards others. The services of an excavator was employed to cut the slope. Dimensions were (10m by 4m) and at an angle of 60.

SCOUTING - A DIFFERENT DEFINITION OF FUN

Site investigation was done to identify a span of suitable sites from which one was chosen for the project. This was followed by a fun activity by team members. As another form of hiking, we went through the farms and bushes to scout for our four geotextiles. These were the palm fronds, the maize stalk, elephant grass and bamboo sticks. This was then followed by gathering of the geotextiles. The question one may ask is; why were these geotextiles chosen?

INCEPTIONS

The team of young intellectuals arrived on site in the very last week of February, 2018. This was on one sunny afternoon at Yongwa. A whole day was taken to settle as well as familiarize ourselves with the environment and the locals of the community.

The Birth of Best Geotextiles

To enhance biodiversity through slope stability, there is the need to understand the essence of geotextiles, compare them in terms of their ability to promote biodiversity in the mining, quarrying and other operations. Research shows that, not only does geotextile stabilize slopes but help to check erosion better, help retain more topsoil, providing better medium to increase flora and fauna.

The Two Young Intellectuals

We wish to introduce the members of the research team working on this project. The team is made up of two young intellectuals, Emily Bansah and Jamez Bayong from the University of Mines and Technology, Tarkwa, Ghana. Emily Bansah is a final year Geological student while Jamez Bayong is a final year mining student.
