(ASCE, 1/1/2020 1)A numerical investigation of near-field brine discharge dynamics is reported for the Gold Coast Desalination Plant offshore inclined multiport brine diffuser. Quasi-steady computational fluid dynamics simulations were ... -
Erodibility of Mud–Sand Bed Mixtures
(ASCE, 1/1/2020 1)The erodibility of mud–sand bed mixtures has been studied based on experiments in a flume and in a small, vertical tube placed on the bed (Eromes-tube of 100 mm diameter with rotating propeller). Two natural mud–sand ... -
Bearing Capacity of Circular Footing Resting on Fiber-Reinforced Pond Ash Overlying Soft Clay
(ASCE, 1/1/2020 1)Model footing tests were conducted of a circular footing resting on a randomly distributed fiber-reinforced pond ash (RDFP) layer overlying soft clay. The effect of varying the thickness of the pond ash layer over soft ... -
Assessment of Arsenic and Heavy Metal Pollution in Chhattisgarh, India
(ASCE, 1/1/2020 1)Natural contamination of arsenic (As) and heavy metals (HMs) poses a health threat in many regions. Ambagarh Tehsil, Rajnandgaon, Central India, is a heavily polluted area due to mineralization of geogenic As and HMs in ... -
Interaction of Landfill Leachate with Compacted Lateritic Soil Treated with <i>Bacillus coagulans</i> Using Microbial-Induced Calcite Precipitation Approach
(ASCE, 1/1/2020 1)The performance of lateritic soil treated with Bacillus coagulans (B. Coagulans) was assessed for use as hydraulic barrier material in municipal solid waste (MSW) containment use. The soil was classified as A–4(2) and SC ... -
Hydrodynamic Modeling of Radionuclide Effluent in Moticher Lake, Kakrapar Atomic Power Station, India
(ASCE, 1/1/2020 1)Radioactive effluent is generated through a nuclear fuel cycle involving the use of radioactive materials in nuclear power plants. The concentration of the nuclear effluent is of concern if it is discharged into a natural ... -
Tree Bark as a Bioindicator for Arsenic and Heavy Metal Air Pollution in Rajnandgaon District, Chhattisgarh, India
(ASCE, 1/1/2020 1)Rajnandgaon district (Chhattisgarh, India) faces serious arsenic pollution problems. Tree bark could be a valuable indicator of As and heavy metals air contamination. In this study, road dust was sampled in 13 locations, ... -
Contamination, Sources, and Environmental Hazards of Groundwater in Bemetara District, Chhattisgarh, Central India
(ASCE, 1/1/2020 1)The groundwater of the the Bemetara district of Chhattisgarh in central India over a large area is hard in nature due to its high mineral content. An elevated concentration of Na+, Mg2+, Ca2+, and SO42− in the groundwater ... -
Neutralization of Red Mud with Organic Acids and Assessment of Their Usefulness in Abating pH Rebound
(ASCE, 1/1/2020 1)This study provides a practical and efficient alternative to neutralize the exorbitant pH of red mud (>11.5) followed by long-term sustenance of the neutralization. The usefulness of organic acids (oxalic acid and citric ... -
Terrace Abandonment Hazards in a Mediterranean Cultural Landscape
(ASCE, 1/1/2020 1)The phenomenon of the abandonment of terraced landscapes compromises environmental well-being and is a preamble to hydrological instability and, consequently, the collapse of terrace retaining walls, soil erosion, and loss ... -
Bioaccumulation of Nutrients and Toxic Elements with Macrophytes
(ASCE, 1/1/2020 1)Macrophytes (aquatic plants or hydrophytes) are sources of food and oxygen for aquatics (e.g., fish, invertebrates) and act as bioindicators for the assessment of environmental conditions in water reservoirs. This ... -
Microbial Consortium–Based Conversion of Dairy Effluent into Biofertilizer
(ASCE, 1/1/2020 1)Dairy wastewater (DWW) is nutritionally rich and extremely hazardous to the environment if discharged untreated. The conventional treatment is time-, labor-, and energy-intensive. A tailor-made microbial consortium converted ... -
