  • Laboratory Investigation of Earth Walls Simultaneously Reinforced by Strips and Random Reinforcement

    The performance of reinforced earth structures depends, among other factors, on the shear strength of the backfill material used in construction. The shear strength can be enhanced by the use of random reinforcement. This paper presents the result of laboratory investigations concerning the effects of several types of random reinforcement on soil strength and, in particular, on the performance of ...

  • Experimental investigation on GFRP strengthened RC piles under lateral loads

    Piles could be damaged under major lateral loading environment for a long period. The sources of lateral loads are lateral earth pressure, wind loads, seismic loads, impact loads from ships (berthing and mooring) eccentric loads on columns, river current and mud movement loads in alluvial settings (foundations subject to scour), ocean wave forces, slope movements and cable forces on transmission ...

  • Construction and operation costs of constructed wetlands treating wastewater

    Design data from nine constructed wetlands (CW) facilities of various capacities (population equivalent (PE)) are used to estimate construction and operation costs, and then to derive empirical equations relating the required facility land area and the construction cost to PE. In addition, comparisons between the costs of CW facilities based on various alternative construction materials, i.e., ...

  • Sustainable development: the options

    Global warming is considered in the context of options for achieving sustainable development. There is some uncertainty over global warming processes, so the Climate Change Convention struck the right balance. The Earth Summit reinforced the concept that economic development and environmental management are interdependent, and resources to solve environmental problems must be targeted carefully. ...

  • Dam Removal, Gob Fire - Case Study

    Coal Gob Fire Quenching – Wellston, Ohio Removal of a dead lake from a former coal mine in Southern Ohio. While working on removal of a dead lake we uncovered a burning gob fire. We moved 45,000 cubic yards of cut to fill and cut to waste, installed 36" reinforced concrete pipe to relieve the dam, and dewatered over 100 million gallons. We moved over 16,000 cubic yards of earth to ...

  • ArmorMax® is Solution for Alberta, Canada Transportation case study

    Background In Alberta Canada. Alberta Transportation identified two ditches. H614:02 north ditch and H894:04 east ditch that had experienced severe erosion. Both ditches service drainage needs for adjacent farmland that comprises hundreds of acres of land. The bed slopes on the two ditches averaged approximately 7%, which enabled the silty soils to easily erode even during modest storm ...

  • Coal and fuel burning effects on the atmosphere as mediated by the atmospheric electric field and galactic cosmic rays flux

    Emissions into the atmosphere of Greenhouse Gases (GHGs) and particulate matter resulting from fossil fuel burning are considered to be the main anthropogenic forcing on the global climate. We show here that the external cyclic influences of cosmic origin that modulate the earth's climate may either reinforce or mitigate the 'local' terrestrial forcings. Among the external influences is cosmic ...

  • Gordy Pump Station - St. Mary Parish Gordy, LA case study

    The first levee armoring project designed by the New Orleans District of the Corp of Engineers (COE) post Hurricane Katrina utilized Armor-Max®, an Anchored Reinforced Vegetation System. It was installed in December 2006 on the land side of the levee to prevent erosion from overtopping. ArmorMax® is a combination of a high performance turf reinforcement mat (HPTRM) and earth percussion ...

  • ArmorMax stands up to Hurricane Gustav and IKE case study

    When Hurricane Katrina made landfall on August 29, 2005 it caused devastating flood damage to large portions of southeastern Louisiana—but it was not the only hurricane to hit the area that year. Hurricane Rita made landfall in late September, causing catastrophic tidal inundation to the community of Lafitte as it passed south of Jefferson Parish, Louisiana. One of the many levees that ...

  • Important Facts About Saltwater Remediation

    Soil that has suffered erosion due to salt, generally becomes useless to any kind of vegetation. This soil becomes crusty and if a lot of acreage is involved, it can cause upsets in ecosystems as well. While researchers have found some ways to treat these areas, the time those processes took were long and tedious. Thanks to today's technology for ...

  • TMDL support activities for the Anacostia river case study

    States and EPA are required to establish Total Maximum Daily Loads (TMDLs) for waterways that fail to support their designated uses (e.g., swimming, recreation, aesthetic enjoyment, etc.) under the Clean Water Act. These TMDLs typically establish strict pollutant load limits for municipalities, industries, and other sources such as agriculture. Problem TMDLs can be challenging and ...

  • Using Coir Geotextiles for soil erosion control

    One of the most effective and yet natural soil erosion prevention techniques is the use of Coir Geotextiles fabrics ( Woven Geotextiles). Used extensively to prevent environmental degradation Geotextiles have no synthetic material but is instead made out of an organic fiber, coir, which is extracted from the husk of a coconut. It is strong, durable, water proof and is one of the few natural ...

  • Issue highlight: Air Effluent Control RotaBed Scrubber: One way to meet Cluster Rules in the bleach plant case study

    The so-called Cluster Rule promulgated by the US EPA at the end of 1997 seeks to legislate control of both air and water emissions under one, all-encompassing regulation. With proper design and application, Cluster Rule requirements can be met easily and economically on modern kraft bleaching sequences using fluidized bed gas scrubbing technology such as the Rotabed, a product of Bionomic ...
