--- title: "Case Study: Slope Erosion Control Project in Jaipur, Rajasthan " date: 2024-05-30 author: "Pawan Khatri" url: https://oceangeosynthetics.com/slope-erosion-control-project-jaipur/ --- May 30, 2024 | [Case Studies](https://oceangeosynthetics.com/category/case-studies/) # Case Study: Slope Erosion Control Project in Jaipur, Rajasthan  For a local government authority in Jaipur, Rajasthan, Ocean Non Wovens supplied 11,600 square metres of Ocean [Erosion Control Mat](https://oceangeosynthetics.com/products/erosion-control-mats/) (Jute Type-2) to stop severe erosion on a slope that was threatening its own stability and the infrastructure around it. The project ran for 3 months. ## Project details - **Location:** Jaipur, Rajasthan - **Product used:** Ocean Erosion Control Mat (Jute Type-2) - **Quantity:** 11,600 square metres - **Duration:** 3 months - **Client:** Local Government Authority The aim was a sustainable [erosion control](https://oceangeosynthetics.com/solution/erosion-control/) solution. After a site assessment, our team recommended the jute mat: a biodegradable product that protects the soil surface while vegetation establishes. ## Why bare slopes erode Slope erosion is the removal of topsoil by runoff, wind or human activity. In Jaipur, most of the year’s rain falls in the July–September monsoon, often in short, heavy bursts that strip bare soil quickly. Left unchecked, erosion causes: - Loss of fertile topsoil - More sediment in nearby water bodies - Less usable land - Damage to infrastructure ## Common erosion control methods - **Vegetative cover:** grass, shrubs and trees whose roots bind the soil. - **Terracing:** steps cut into the slope to slow runoff. - **Retaining walls:** structures that hold back the soil. - **Erosion control mats:** synthetic or natural mats that cover the soil and stop it moving. Vegetation is the long-term answer on most slopes, but seed and young grass wash away in the first heavy rain. A mat protects the surface during that window. ## Ocean Erosion Control Mat (Jute Type-2) The jute mat is made for slope stabilisation and erosion prevention. Its open weave breaks the impact of raindrops and slows runoff across the surface, while grass grows up through the gaps. Reasons it was chosen: - **Biodegradable:** made from natural jute fibres, it breaks down over time and adds organic matter to the soil. By then, the roots have taken over its job. - **Tensile strength:** holds together on the slope and supports the soil surface. - **Moisture retention:** jute absorbs water and keeps the soil beneath it damp, which helps seeds germinate in a dry climate. - **Easy installation:** rolls are laid quickly over large areas. ### Technical specifications - **Material:** 100% natural jute fibres - **Weight:** 500 grams per square metre - **Thickness:** 6 mm - **Tensile strength:** 20 kN/m ## Installation ### Site preparation The slope was cleared of debris and loose soil, and existing vegetation was trimmed so the mat could lie flat against the soil. Good contact matters: water running under a mat that bridges hollows can erode the soil beneath it. ### Laying, anchoring and seeding - **Laying:** the mat was rolled out over the prepared slope, with overlaps so no soil was left exposed. - **Anchoring:** biodegradable stakes at regular intervals held the mat against wind and water. - **Seeding:** grass seed was spread so plants could grow through the jute. As standard practice, the top edge of the mat is buried in an anchor trench at the crest of the slope, rolls run downslope, and each upslope roll overlaps the one below so runoff flows over the joint rather than into it. ### Monitoring and maintenance The mat was inspected regularly. Displaced sections were repaired promptly, and bare patches were reseeded where needed. ## Results Within weeks of installation, the mat was working: the slope stayed stable through heavy rain, with no noticeable soil displacement. Over the longer term: - **Vegetation:** grass and other plants established through the mat and now hold the soil. - **Soil enrichment:** as the jute decomposed, it added organic matter and improved fertility. - **No residue:** the mat biodegrades, leaving no synthetic material on the slope. ## Lessons for similar projects - **Match the solution to the site:** slope angle, soil, rainfall and how long protection is needed decide between a biodegradable jute or [coir](https://oceangeosynthetics.com/products/geotextile-manufacturers/coir-geotextile/) mat and a permanent synthetic one. - **Monitor:** early inspection and repair during the first monsoon decides whether vegetation takes hold. - **Involve the community:** local involvement in upkeep makes the result last longer. ## Erosion control from Ocean Non Wovens In Jaipur, 11,600 square metres of Ocean Erosion Control Mat (Jute Type-2) held a bare slope through the rains until grass could take over.
