Accurate prediction of salinity in Chott Djerid shallow aquifers, southern Tunisia: Machine learning model development

Kraiem, Zohra; Zouari, Kamel; Chkir, Najiba

2024 Water Science

doi:10.1080/23570008.2023.2294535

A backpropagation neural network (BPNN) was used to predict salinity levels in the Chott Djerid shallow aquifers. A set of 51 water samples was collected from the Chott Djerid plio-quaternary aquifers for geochemical analysis. Major elements and nitrates were ascertained by using high...

Pesticides’ low-cost removal from polluted groundwater using charcoal from “Salix mucronata” trees activated by gold nitrate

Elsaid, Saad Mohamed; Anwar, Nabil; Roushdi, Mahmoud

2024 Water Science

doi:10.1080/23570008.2023.2290764

Used pesticides result in soil pollution, which potentially seep into groundwater, posing risks to human and animal health. The current study examines the use of a new cheap material for removing four commonly used pesticides from polluted groundwater before use for drinking. These pesticides...

Investigation of riprap stability at downstream of spillway flip bucket without and with energy dissipators

Niroubakhsh, Mehdi; Masjedi, Alireza; Heidarnejad, Mohammad; Bordbar, Amin

2024 Water Science

doi:10.1080/23570008.2023.2300210

Spillway is one of the most cost-effective energy dissipating structures used in dams which leads to dissipation of flow energy at the end of the structure. Scouring is a phenomenon occurring next to the hydraulic structures, and which can lead to deterioration and even collapse of such...

Efficient and cost-effective adsorbent brick sand nanoparticles used for removal of heavy metals

Karim, Anwarul; Hossain, Delwar; Hossain, Ismail; Dipti, Sharmin Sultana; Azad, Abul Kalam

2024 Water Science

doi:10.1080/23570008.2024.2307197

We are introducing cost effective, easily available brick sand nano-particles (BSNP) (44.208 nm) as an adsorbent in batch process for removal of heavy toxic metals such as Pb, Cd, and Cr from aqueous solution. We used two types of adsorbents, one is acid treated BSNP and other one is untreated...

Flow behavior over well-escape weirs

Mohamed, Hassan I.; Abozeid, Gamal; Ali, Nashat A.; Saied, Wagdy M.

2024 Water Science

doi:10.1080/23570008.2024.2307223

Weirs play an important role in controlling and managing water in irrigation canal networks through several functions, such as discharge measurements, water distribution, and lowering the water level. Weirs also play a crucial role in protecting canals from flooding, which might cause the...
