RISBernoulli–Gaussian Model with Model Parameter Estimation
Publisher: American Society of Civil Engineers
Abstract: First, this paper introduces a statistical model of gross errors, namely the Bernoulli–Gaussian (BG) model, which characterizes the gross error as a product of a Bernoulli variable and a Gaussian variable. The BG model ...

Hydraulic Conductivity of Sand/Biopolymer-Amended Bentonite Backfills in Vertical Cutoff Walls Permeated with Lead Solutions
Publisher: ASCE
Abstract: This study investigated the hydraulic conductivity and microscopic properties of two backfills, conventional sand/bentonite (SB) and sand/xanthan gum (XG)-amended bentonite/sand (XG-SB), for use in vertical cutoff walls ...
Fouling Elimination of PTFE Membrane under Precoagulation Process Combined with Ultrasound Irradiation
Publisher: American Society of Civil Engineers
Abstract: Precoagulation is one of the effective pretreatments in membrane filtration. This process mitigates membrane fouling, which is the major drawback of membrane technology in drinking water and wastewater treatment. This study ...

Effect of Polymer Amendment on Hydraulic Conductivity of Bentonite in Calcium Chloride Solutions
Publisher: ASCE
Abstract: Hydraulic conductivity of polyanionic cellulose (PAC)–amended bentonite (PB) in calcium chloride (CaCl2) solutions was investigated to access its chemical compatibility in vertical cutoff walls application. PB was synthesized ...
