Environmental archaeology of archaeological sites on both sides of the Dachang section in the Daning River, the Three Gorges of the Yangtze River, shows that riverbed evolution has a great influence on the distribution of archaeological sites during the prehistorical and historical period, and it restricts human activity and the development of ancient culture. Field investigation, dating data, ...

Oocysts of the protozoan pathogen Cryptosporidium parvum are of particular concern for riverbank filtration (RBF) operations because of their persistence, ubiquity, and resistance to chlorine disinfection. At the Russian River RBF site (Sonoma County, CA), transport of C. parvum oocysts and oocyst-sized (3 μm) carboxylate-modified microspheres through poorly sorted (sorting indices, σ(1), up to...

Changes in riverine hydrography and reduced aquifer recharge due to projected climate changes arid semi-arid regions are the main issues of water supply, especially Nile Delta, Egypt. Continuous degradation results from flow, poor management groundwater extraction, human activities throughout Nile’s course drainage channels. Contamination this with heavy metals dissolved organic solids reduces ...

Riverine systems are directly affected by plastic pollution and function as pathways for transport to the sea. Plastic litter can enter water remobilization from bed or riverbank, after which it be transported with flow. The process of is still poorly understood. To get a detailed understanding role rivers play in hence develop management measures prevent mitigate vital fundamental factors cont...

Anthropogenic litter is omnipresent in terrestrial and freshwater systems, can have major economic ecological impacts. Monitoring modeling of anthropogenic comes with large uncertainties due to the wide variety characteristics, including size, mass, item type. It unclear as what effect sample set size on reliability representativeness statistics. Reliable statistics are needed (1) improve monit...

Abstract Riverbank erosion often compels affected people to migrate from their respective communities. However, there are still many who do not leave the region. The research focuses on this particular group of non-migrant populations living in erosion-prone Ramdaspur village Bhola district Bangladesh, explore how influences (non-)migration decision. We interviewed households study village. Mor...
