the aim of this study was to assess the environmental impact of socio-cultural practices on the water quality of river ganga at the foothills of the garhwal himalayas in uttarakhand state, india. the physico-chemical parameters that contributed to the temporal variation and pollution in the river were identified in this study. principal component analysis (pca) and cluster analysis (ca) were us...

Kent State had its beginning nearly a century ago. William S. Kent, a person of vision, donated 53 acres of farmland located on a hill overlooking a small town on the Cuyahoga River. He did so to establish a teacher education school in his community. When I visit various communities in my travels, I always ask, Why does this community or city exist? What is its reason for being? Kent exists bec...

The Columbia River Basin Ethnic History Archive (CRBEHA) project received an Institute for Museum and Library Services (IMLS) leadership grant in September 2001. The grant was titled: Engaging the Public with Digital Primary Sources: A Tri-State Online History Database and Learning Center. The institutions involved in the project were Washington State University Vancouver, Washington State Univ...

http://dx.doi.org/10.1590/0102-311X00000616 An emblematic case of journalism that is contrary to the public interest was the coverage, by newspapers O Globo and Folha de S. Paulo about the worst socioenvironmental disaster in Brazil, which affected the municipality of Mariana, Minas Gerais State, and the entire Doce river valley, caused by mining company Samarco, a joint venture between Brazili...

The study analyzed agricultural extensification and biodiversity loss in Cross River State, Nigeria. The study used primary data with the aid of a well-structured questionnaire to collect data from one hundred and ten respondents (110) through simple random sampling technique. Data collected were analyzed using descriptive statistics as well as inferential statistics. The results revealed that ...

Rapid land loss in the Mississippi River Delta Plain has led to intensive efforts by state and federal agencies for finding solutions in coastal land restoration in the past decade. One of the proposed solutions includes diversion of the Mississippi River water into drowning wetland areas. Although a few recent studies have investigated flow-sediment relationships in the Lowermost Mississippi R...

River water quality models are used extensively in research as well as in the design and assessment of water quality management measures. The application of mathematical models for that purpose dates back to the initial studies of oxygen depletion due to organic waste pollution. Since then, models have been constantly refined and updated to meet new and emerging problems of surface water pollut...

The reproductive migration of anadromous salmonids through estuarine waters is one of the most challenging stages of their life cycle, yet little is known about the environmental and physiological conditions that influence migratory behaviour. We captured, sampled tissues, tagged and released 365 sockeye salmon (Oncorhynchus nerka) homing through inner coastal waters towards the Fraser River, B...

The widespread urbanization of the corridor of the Sarno River has drastically modified the environment of this fluvial system. The aerial recognitions show that “the river continuum” was replaced by a continuum of town centres developed along the course of the Sarno River and its tributaries often on both banks. The urban and industrial building areas appear as a continuum and the agricultural...

We present an approach for identifying groundwater discharge chemistry and quantifying spatially distributed groundwater discharge into rivers based on longitudinal synoptic sampling and flow gauging of a river. The method is demonstrated using a 450 km reach of a tropical river in Australia. Results obtained from sampling for environmental tracers, major ions, and selected trace element chemis...
