“…Land use and land cover change is strongly correlated with water chemistry parameters (Hunsaker and Levine 1995;Tran et al 2010), the species diversity of freshwater fish and macro-invertebrates (Hopkins 2009;Weijters et al 2009), and sediment metal concentrations (Hollister et al 2008). Highly fragmented urban land uses, with a large proportion of impervious surfaces, tend to increase river flow and negatively affect water quality (Sliva and Williams 2001;Brabec 2009;Lee et al 2009). The problem of soil erosion is severe in some areas because of rapid urban development in recent decades (Ho and Hui 2001).…”

Although water constitutes 71% of the earth's surface, only 0.3% of it is available as fresh water for human use. Moreover, the quality of fresh water in ground and surface systems is of great concern, as potable water needs to have appropriate mineral content. Ground and surface water quality in rural and urban environments is affected by both natural processes and anthropogenic influences. Because of this, water is becoming scarcer as the population increases across the world. Natural processes leading to changes in water quality include weathering of rocks, evapotranspiration, depositions due to wind, leaching from soil, run-off due to hydrological factors, and biological processes in the aquatic environment. These natural processes cause changes in the pH and alkalinity of the water, and also phosphorus loading, increase in fluoride content and high concentrations of sulphates. Anthropogenic factors affecting water quality include impacts due to agriculture, use of fertilizers, manures and pesticides, animal husbandry activities, inefficient irrigation practices, deforestation of woods, aquaculture, pollution due to industrial effluents and domestic sewage, mining, and recreational activities. These anthropogenic influences cause elevated concentrations of heavy metals, mercury, coliforms and nutrient loads. This paper studies the effects of natural processes and human influences in rural and urban aquatic systems. Pollution due to environmental parameters such as heavy metal pollution, heavy metals and bacterial and pathogenic contamination of both urban and rural areas is discussed in detail.

“…Many studies have reported that the land use types and patterns within a watershed determine the characteristics of human activities, which in turn determine the anthropogenic substances carried into river systems (Omernik et al, 1981;Lenat and Crawford, 1994;Bolstad and Swank, 1997;Gburek and Folmar, 1999;Liu et al, 2000;Tong and Chen, 2002;Lee et al, 2009). Moreover, land uses within a watershed can impact various intrinsic attributes of river systems, including hydrological, geomorphological, chemical, and biological aspects (Omernik et al, 1981;Osborne and Wiley, 1988;Richards et al, 1993;Richards et al, 1996;Allan et al, 1997).…”

-This paper provides an overview of the development and application of the National Aquatic Ecological Monitoring Program (NAEMP) in Korea, which uses biological and habitat-riparian criteria for river/stream and watershed management. Development of NAEMP began in 2003, with recognition by the Korean Ministry of Environment (MOE) of the limitations of applying chemical parameters (e.g., biochemical oxygen demand (BOD)) as the principal targets of water environment management. Ecosystem health criteria under NAEMP were developed from 2003 to 2006. Candidate sites for monitoring were also screened and established across the country. NAEMP was implemented in 2007, and since then a standard protocol of nationwide monitoring based on multi-criteria has been implemented to assess the ecological condition of rivers and streams. The monitoring results indicate that many Korean rivers and streams are severely degraded, with biological conditions that are much worse than their water chemistry suggests. In 2009, 24% of rivers and streams were in classes C (Fair) and D (Poor) for BOD, but more than 71, 53, and 27% were categorized as Fair to Poor according to fish, diatom, and benthic macroinvertebrate assemblages, respectively. NAEMP is promising in that the results have already had great impacts on policy making and scientific research relevant to lotic water environment and watershed management in Korea. In the future, NAEMP results will be used to develop more aggressive regulations for the preservation and restoration of rivers/ streams, riparian buffer areas and watersheds. Another future aim of the NAEMP is to develop aquatic ecological modeling based on the monitoring results.

Provavelmente, a baixa precipitação acontecida de forma anormal durante o ano avaliado não proporcionou escoamento superficial suficiente para que houvesse o transporte de nutrientes.…”
