“…The numerous dams and reservoirs built in the upper Yangtze River basin, particularly after the construction of the Three Gorges Dam, have reduced the delivery of TP to the middle and lower basins by 77% (Zhou et al, 2013). The retention of reactive P in Luxembourg's terrace dams increases progressively after passing through each dam (Salvia-Castellvi et al, 2001). Currently, research on the cumulative effects of cascades is insufficient, which is an urgent problem to solve.…”

In recent decades, damming has become one of the most important anthropogenic activities for river regulation, and reservoirs have become hotspots for biogeochemical cycling. The construction of dams changes riverine hydrological conditions and alters the physical, chemical, and biological characteristics of rivers, eventually leading to significant variations in nutrient cycling. This review mainly explores the effects of river damming on nutrient transport and transformation, including i) nutrient (N, P, Si, and C) retention in reservoirs, ii) greenhouse gas (GHG) emissions, and iii) interactions between the nutrient stoichiometry ratio and the health of the reservoir ecosystem. The important drivers of nutrient transport and transformation, such as river connectivity, hydraulic residence time, hydropower development mode, microbial community variation, and anthropogenic pollution, have also been discussed. In addition, strategies to recover from the negative effects of damming on aquatic ecosystems are summarized and analyzed. To provide theoretical and scientific support for the ecological and environmental preservation of river-reservoir systems, future studies should focus on nutrient accumulation and GHG emissions in cascade reservoirs.

“…Surface water retention systems have shown success in reducing nutrient and sediment loading in various locations worldwide. Within America and Europe, retention systems have reduced total nitrogen by 38-56% and total phosphorus by 17-82%, with reduction levels dependent on the size and type of retention system (Tiessen et al 2011;Sharpley et al 1996;Kovacic et al 2006;Salvia-Castellvi et al 2001;Avilés and Niell 2007;Uusi-Kämppä et al 2000). On the Canadian Prairies, dams were found effective in reducing total suspended sediment (65-85% reduction), particulate nitrogen (41-43% reduction during snowmelt, 7-11% reduction from summer rainfall events), and particulate phosphorus (27-38% reduction in snowmelt runoff) (Agriculture and Agri-Food Canada 2012).…”

An economic assessment of local farm multi-purpose surface water retention systems in a Canadian Prairie setting

There is a need to explore more sustainable approaches to water management on the Canadian Prairies. Retention pond installation schemes designed to capture surface water may be a viable option that would reduce water stress during drought periods by providing water for irrigation. The retention systems would serve to capture excess spring runoff and extreme rainfall events, reducing flood potential downstream. Additionally, retention ponds may be used for biomass production and nutrient retention. The purpose of this research was to investigate the economic viability of adopting local farm surface water retention systems as a strategic water management strategy. A retention pond was analyzed using a dynamic simulation model to predict its storage capacity, installation and upkeep cost, and economic advantage to farmers when used for irrigation. While irrigation application increased crop revenue, the cost of irrigation and reservoir infrastructure and installation costs were too high for the farmer to experience a positive net revenue. Farmers who harvest cattails from retention systems for biomass and available carbon offset credits can gain $642.70/hectare of harvestable cattail/year. Cattail harvest also removes phosphorus and nitrogen, providing a monetized impact of $7014/hectare of harvestable cattail/year. The removal of phosphorus, nitrogen, carbon, and avoided flooding damages of the retention basin itself provide an additional $17,730-$18,470/hectare of retention system/year. The recommended use of retention systems is for avoided flood damages, nutrient retention, and biomass production. The revenue gained from these functions can support farmers wanting to invest in irrigation while providing economic and environmental benefits to the region.

“…Pollution from agriculture and sewage is recognized as having a significant negative impact on water quality and aquatic biota [2], besides the fish stock [3]. The biological reaction of aquatic system to nutrient enrichment is the eutrophication, the eventual conesquence of which is the development of primary production to nuisance proportions [4]. Free dissolved phospho-rus and nitrogen are important nutrients for photosynthetic organisms [5], mainly for cyanobacterial blooms [6,7].…”

The seasonal development of the phytoplankton, phytobenthos, zooplankton, and microbenthos in a high eutrophised intravilan water reservoir was studied. Finally, 25 genera with 44 species of Cyanobacteria/Cyanophytes and 67 genera with 102 species as well as infraspecific taxa of different groups of microscopic algae were identified. The phytoplankton in most parts of the water basin was strongly dominated by green colonial alga Golenkiniopsis longispina. From October until December a cyanophyte species Aphanocapsa delicatissima with typical cell dimensions of picoplankton/ was found in large amounts/predominated. As early as spring, a plankton bloom in all its components was observed. At that time, also a high concentration of total phosphorus was recorded, which in the second half of April dropped rapidly. The concentration of chlorophyll-a increased from 162.7 μg/L in March to 2322 μg/L in September. Massive occurrence of benthic protozoa in the plankton, as a consequence of anoxia, has been observed. Further, the detritivore and omnivore ciliate species Coleps hirtus dominated in the microbenthos. Altogether 74 of ciliate taxa were detected. Their abundance and biomass reached peak in April, but these steadily decreased from May until the end of the year. Extreme values of zooplankton density (54,016 ind/L) were recorded in spring followed by a sudden fall in summer and autumn. The contribution of rotifers (Brachionus spp., Filinia longiseta) in the total zooplankton density and biomass was 98%. Relatively a low species richness of crustaceans (4 Cladocera and 3 Copepoda) was observed.
