Existence of these soils, sometimes with high gypsum content, caused difficult problems to the buildings and strategic projects due dissolution leaching by action waterflow through soil mass. In this research, a new technique is adopted investigate performance replacement geosynthetic reinforcement materials improve gypseous behavior experimential set up manufactured loaclally specially for wor...

Abstract Way Hawang Beach, one of coastal tourist attraction, located in Village, Maje, Kaur Regency, Bengkulu Province is suffering from erosion. The regular erosion speed approximately 2 to 3 meters/year, taking the distance coastline West Sumatra Causeway which around 250 meters. Efforts eradicate abrasion on Coast are mostly carried out using protective structures. One breakwater structures...

Experimental materials currently being investigated for use as amendments for the in situ remediation of contaminated sediments were assessed for their potential impacts on marine benthos. Laboratory toxicity tests involving lethal and sublethal endpoints were conducted on sediments amended with apatite, organoclay, chitin, or acetate, with the polychaete Neanthes arenaceodentata, the amphipod ...

Filtration performance of woven geotextiles is strongly related to their pore structure parameters, i.e., percent open area (POA) and pore-opening size distribution (PSD). Current methods of determination of pore structure parameters contain inherent disadvantages, whereas image analysis, taking advantage of the two-dimensional structure of woven geotextiles, can be used effectively for this pu...

Hydraulic dredging of stormwater ponds may include on-site dewatering dredged materials using polymers and geotextile filtration. The choice polymer its preparation affect the overall operational effectiveness quality reject water (filtrate) returned to pond. This study examined resulting particle content as well nutrient metal concentrations in filtrate conducted on hydraulically sediment that...

This research investigated the effects of types cohesive-frictional soil and geotextile reinforcement configurations on bearing capacity reinforced foundation (RSF) structures, via laboratory test numerical simulation. The four studied for RSF included: (i) horizontal planar form geotextile, (ii) full-wraparound ends (iii) with filled-in sand, (iv) sand backfill. soils were mixtures fine sodium...
