Traditional flood control systems always have a conflict with natural ones, i.e., rivers in cities are usually straight and smooth, whereas natural ones are according to ecological mechanisms. Social and economic developments in the modern world require a new system combining ecological needs and traditional flood control system. Ecological flood control systems were put forward and defined as ...

Over the past few decades, glaciers worldwide have been retreating, resulting in changes in water resources with direct socio-environmental impacts. The flow of glaciers is intrinsically linked to the morphology and dynamics of sub-glacial water. However, these sub-glacial processes remain largely mysterious, and current techniques of modeling the glacial flow based on these sub-glacial structu...

Water a vital component for all living forms is derived from variety of sources, including surface water (rivers, lakes, reservoirs and ponds) and ground water (aquifers). Over the years of time, water bodies are subjected to human interference regularly resulting in deterioration of water quality. Therefore, pollution of water bodies has become matter of global concern. As the water quality cl...

The taxonomy and ecology of the cyclopoid copepod genus Thermocyclops were studied. Samples were collected in 207 water bodies located in the 22 hydrographic basins of São Paulo State, Brazil, including large reservoirs, small and shallow lakes, and ponds and rivers. The genus Thermocyclops inhabits mainly water bodies within a limnetic region. Four species were found, of which one is new: Ther...

The study was conducted to assess the impact of traditional jute retting process on the fish health and fish biodiversity in the six upazilas of Chandpur district, Bangladesh. Data were collected from respondents through face to face interviews and focus group discussions. All of the jute farmers in the study area used traditional water retting methods to extract fibres and these methods were e...

A serious concern for managers of water resources, pathogens in the urban environment easily enter waters through a number of pathways, including discharge of inadequately treated sewage, stormwater runoff, combined sewer overflows and sanitary sewer overflows. Pathogens in US ambient water bodies are regulated under the Clean Water Act (CWA), while pathogens in drinking water supplies are regu...

Non-tuberculous mycobacteria (NTM) inhabit a wide variety of environmental including different water bodies, soil, aerosol, animals and humans. NTM are also known as environmental mycobacteria which can cause mycobacteriosis .Humans, animals and fresh water fauna are exposed to mycobacteria in water. HIV seronegative and immunocomprised patients are most vulnerable to acquire this opportunistic...

Traditional on-site methods for mapping and monitoring surface water extent are prohibitively expensive at a national scale within Canada. Despite successful cost-sharing programs between the provinces and the federal government, an extensive number of water features within the country remain unmonitored. Particularly difficult to monitor are the potholes in the Canadian Prairie region, most of...

This paper focuses on the spatio-temporal effects of urbanization on surface water resources in Wuhan, China. Specifically, the relationships between surface water bodies and their surrounding land use changes are discussed quantitatively by remote sensing (RS) and geographic information system (GIS). In this paper, surface water bodies and land use classifications in 1991 and 2005 are detected...
