  • Drainage System Stabilization Project case study

    In 1997, a residential development was built upslope from this golf course drainage ditch. It began to erode, but because the ditch was filled with invasive species such as Blackberry and Reed Canary Grass, the erosion was not visible. When the non-native plants were removed to create a new golf course hole, the erosion was evident – in some places more than four feet deep, all the way ...

  • ArmorMax® is Solution for Bank Stabilization in NRCS Emergency Watershed Protection Program, Kissimmee, FL case study

    PROJECT SUMMARY Years of flash flooding and fluctuating water levels in the West City Ditch made for a dangerous scenario. The City of Kissimmee secured NRCS EWPP grant money to stabilize the ditch before catastrophic infrastructure damage occurred, but the budget was too small for full protection with conventional hard armoring. Propex worked with engineers to model slope stability in rapid ...

  • Impact of elevated Ca2+/Mg2+ concentrations of reverse osmosis membrane desalinated seawater on the stability of water pipe materials

    Hardness and alkalinity are known factors influencing the chemical stability of desalinated water. This study was carried out to investigate the effect of Ca2+ and Mg2+ on corrosion and/or scale formation on the surface of different water distribution pipe materials under tropical conditions.

  • Evaluation of corrosion and scaling tendency indices in a drinking water distribution system: a case study of Bandar Abbas city, Iran

    Corrosion and scaling is a major problem in water distribution systems, thus evaluation of water corrosivity properties is a routine test in water networks. To evaluate water stability in the Bandar Abbas water distribution system, the network was divided into 15 clusters and 45 samples were taken. Langelier, Ryznar, Puckorius, Larson–Skold (LS) and Aggressive indices were determined and ...

  • The effects of hydroxylated multi‐walled carbon nanotubes on the toxicity of nickel to Daphnia magna under different pH levels

    Hydroxylated multi‐walled carbon nanotubes (F‐MWCNTs), with large amount of hydrophilic groups attached on the nanoparticle surface, have caused considerable concerns of their inevitable releases into the aquatic environments. As one of the F‐MWCNTs, hydroxylated multi‐walled carbon nanotubes (OH‐MWCNTs) may interact with other contaminants such as heavy metals and even influence their ...
