“…Solheim and Gulati (2008) Many studies of this kind however, have a short reach of application within the wide diversity of aquatic ecosystems, due to focus on a limited range of water bodies, for example shallow or oligotrophic lakes with specific characteristics (Leuven et al 1987;Leuven, 1988), or water systems that are under heavy anthropogenic pressure like ditches and streams in agricultural areas (Chambers, et al 2008) and urban drainage systems (Vermonden et al, 2009). This was also the conclusion of Nijboer and Verdonschot (2004) who stated that the sensitivity of a stream to eutrophication depends on local stream characteristics and that this aspect should be included in a generally applicable model.…”

The magnitude of ecological damage caused by elevated phosphorus concentrations in Dutch inland waters was evaluated and expressed as the fraction of disappeared genera. We used national abundance data stored in the Limnodata Neerlandica from 1980 until 2005. We derived the presence or absence in the concentration range between 0.001 and 40 mg/l total phosphorus for 867 macro-invertebrate genera. At concentrations above 0.1 mg/l, which is considered a signal of nutrient enrichment of freshwater, the fraction of disappeared macroinvertebrate genera (DF) can be written as a logistic function of the phosphorus concentration (CP), i.e. DF = 1/(1 + 4.07-CP-111). This implies that half of the macro-invertebrate genera that potentially occur in freshwater in the Netherlands would disappear at a phosphorus concentration of 3.5 mg/l. This field-based impact expression resembles the cumulative sensitivity distribution function for a toxic substance, based on the Species Sensitivity Distribution (SSD) concept and artificial exposure test data. While the SSD for a compound relies on laboratory sensitivity data for a small number of species, the fraction of disappeared macro-invertebrate genera is here derived from field observations of many macroinvertebrate genera at numerous phosphorus concentration intervals. By applying the new damage function to measured phosphorus concentrations over the period in the rivers Rhine, Meuse and Scheldt, we found that the observed change in phosphorus concentrations would imply a loss of macro-invertebrates of 20-30 % initially to 5-10 % in 2005. The cumulative sensitivity distribution function for phosphorus from national freshwater monitoring data can be applied in various environmental screening systems such as multi-stress impact assessment of surface waters and in life cycle impact assessment of products.

“…Ecosystem responses to eutrophication are most studied in standing waters, but nutrient addition also enhances primary production in streams, predominantly of benthic algae (Lawrence and Gresens 2004, Torrecilla et al 2005), but can also enhance growth of pelagic algae (Smith et al 1999). Eutrophication of running waters may lead to reduction of water clarity, taste and odor problems, blockage of intake screens and filters, restriction of swimming and other waterbased recreation, harmful diel fluctuations in pH and in dissolved oxygen concentrations, reduction of habitat quality for macroinvertebrates and fish spawning, and an increase in the probability of fish kills (Nijboer and Verdonschot 2004). Apart from causing eutrophication, enhanced deposition of inorganic nitrogen can also increase the concentration of hydrogen ions in freshwater ecosystems with low acid-neutralizing capacity, resulting in acidification of those systems (Camargo and Alonso 2006).…”

ABSTRACT. Water quality describes the physicochemical characteristics of the water body. These vary naturally with the weather and with the spatiotemporal variation of the water flow, i.e., the flow regime. Worldwide, biota have adapted to the variation in these variables. River channels and their riparian zones contain a rich selection of adapted species and have been able to offer goods and services for sustaining human civilizations. Many human impacts on natural riverine environments have been destructive and present opportunities for rehabilitation. It is a big challenge to satisfy the needs of both humans and nature, without sacrificing one or the other. New ways of thinking, new policies, and institutional commitment are needed to make improvements, both in the ways water flow is modified in rivers by dam operations and direct extractions, and in the ways runoff from adjacent land is affected by land-use practices. Originally, prescribed flows were relatively static, but precepts have been developed to encompass variation, specifically on how water could be shared over the year to become most useful to ecosystems and humans. A key aspect is how allocations of water interact with physicochemical variation of water. An important applied question is how waste releases and discharge can be managed to reduce ecological and sanitary problems that might arise from inappropriate combinations of flow variation and physicochemical characteristics of water. We review knowledge in this field, provide examples on how the flow regime and the water quality can impact ecosystem processes, and conclude that most problems are associated with low-flow conditions. Given that reduced flows represent an escalating problem in an increasing number of rivers worldwide, managers are facing enormous challenges.

“…Nutrient enrichment produces excessive algal growth, which in turn adversely affects stream animal communities (Nordin, 1985). The most common ecological phenomena caused by nutrient enrichment are increases in periphyton biomass (Bourassa and Cattaneo, 1998), shifts in macroinvertebrate communities from sensitive to more tolerant species (Allan, 2004;Chambers et al, 2006), and biodiversity losses (Nijboer and Verdonschot, 2004).…”

-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.
