The City of New Bern upgraded their WWTP to 6.5 mgd in 2002. The City was faced with some of the most stringent effluent limits in the State. The City selected a 5 Stage Bardenpho biological process followed by an RDP EnVessel Pasteurization process to produce a Class A biosolids ...
Geocell is a three-dimensional grid or honeycomb structural material, generally made of high-molecular polymers such as high-density polyethylene (HDPE) and polypropylene (PP). Geocell is a honeycomb three-dimensional structure. As a cellular confinement systems, it can constrain the soil, stone and other materials filled in the cell in a specific space and limit their lateral movement. When ...
Its main uses are slope protection of river, sea, and lake embankments, land reclamation, wharf, ship lock flood control and rescue projects, etc. ...
Introduction Of Geogrid Geogrid is a major geosynthetic material, which has unique properties and efficacy compared with other geosynthetics. It is often used as a reinforcing material for reinforced soil structures or a reinforcing material for composite materials. Geogrids can be divided into the following four categories: plastic geogrids(including PP and PE geogrids), steel-plastic geogrids, ...
The largest allowable deviation is 2% ) Application Field Of Geobags The Geobags has a long service life and is used in engineering projects such as river management and rectification, slope protection, mine rectification, and road beautification. Ecological Restoration 1. On both sides of the river: a natural riparian environment where ...
In the city of Ipswich, a new crossing over the River Orwell faced engineering risks associated with unmapped soft sediments and zones of dissolution in chalk formations. ...
Kunming City, Yunnan Province, China Ecological Laboratories authorized representatives from the United States presented a program for biological remediation of Dianchi Lake using Ecological’s unique bacteriological based products in March 2004. The small, but badly polluted river was offered to Oakwell Engineering as a trial project using products ...
The Guadiana Bridge connecting Portugal and Spain The International Guadiana Bridge is a concrete cable-stayed bridge, located in the southeast of Portugal, connecting Portugal and Spain over the Guadiana River. The bridge, designed by the Portuguese engineer Câncio Martins, was open to traffic in 1991 and was one of the first cable-stayed bridges with a ...

CLIENT: Environment Agency RECLAMATION STRATEGY: Low permeability barrier CONTAMINATION: Flood defence END USE: Flood defence Project Overview There are around 7,500 km of coastal and river flood embankments in England and Wales. Effective performance of these embankments during extreme flood events is critical for the provision of sustainable flood risk management. ...
Estimating peak river discharge, a critical issue in engineering hydrology, is essential for designing and managing hydraulic infrastructure such as dams and bridges. ...
Modeling pollution transmission in rivers is an important subject in environmental engineering studies. Numerical approaches to modeling pollution transmission in rivers are useful tools for managing the water quality. The advection-dispersion equation is the governing equation in the transport of pollution in rivers. ...
Global was contracted by Terra Contracting Services, LLC to serve as Water Treatment Specialists in response to the 2010 Enbridge Oil Spill along the Kalamazoo River. An energy pipeline rupture caused 877,000 gallons of heavy crude oil to spill into Talmadge Creek in Calhoun County, Michigan, which flows into the Kalamazoo River. Global ...
The lagoon system discharges to the Milk River. Stahly Engineering & Associates, Bozeman, MT and the City of Harlem staff conducted a lagoon survey in 2009. ...
There has been an increasing interest in the use of Acoustic Doppler Current Profilers (ADCPs) to characterise the hydraulic conditions near river engineering structures such as dams, fish passes and groins, as part of ecological and hydromorphological assessments. ...
Estimation of daily streamflow time series is of paramount importance for the design and implementation of river engineering and management projects (e.g., restoration, sediment-transport modelling, hydropower). ...
As a result of knowledge about future impacts, the Netherlands is now able to connect its short-term decisions with long term water related challenges such as sea level rise and increased river discharge. The Dutch Delta Commissioner explained how the Netherlands now prefers to ‘work with hard engineering solutions if necessary, but with soft solutions when ...
The hydrological catchments used in the exercise are hydrozones developed by WRP Consulting Engineers for the Orange-Senqu River Commission (ORASECOM). Computation of the original datasets was completed by ISciences, L.L.C. ...
Their permit stipulated effluent limits plus monitoring, sampling and flow measurement of wastewater discharged from the site to the South Raisin river. The Ontario Water Resources Act requires flow monitoring for any quarry dewatering greater than 50,000 liters per day. ...
