Can rainfall dilute the concentration of nutrient in lake water?
Best insight from top research papers
Rainfall can have both diluting and enriching effects on nutrient concentrations in lake water. In some cases, rainfall can dilute the concentration of nutrients, leading to lower nutrient levels in the water. For example, in Lake Malawi, rainfall was found to be dilute with regard to most constituents, except for calcium and bicarbonate ions . Similarly, in Limboto Lake, higher rainfall resulted in higher sediment loads and decreased water transparency, indicating a dilution effect on nutrient concentrations . However, rainfall can also have an enriching effect on nutrient concentrations. In rivers flowing into Lake Taihu, heavy rainfall events increased the concentrations of nitrogen and phosphorus in the water, leading to higher nutrient loading into the lake . In Xin'anjiang Reservoir, rainfall promoted algal growth by increasing nutrient concentrations, particularly phosphorus . Therefore, the effect of rainfall on nutrient concentrations in lake water can vary depending on the specific characteristics of the lake and the surrounding environment.

Why lake restoraation should target reducing phosphate levels to below 50μg L-1?4 answersLake restoration should target reducing phosphate levels to below 50μg L-1 because high phosphorus concentrations contribute to eutrophication, which leads to excessive biological growth and water degradation. Phosphorus is often the limiting nutrient for biological growth in lakes, and its removal is crucial for controlling eutrophication. Studies have shown that reducing phosphorus concentrations can lead to improvements in water quality, such as decreased primary productivity and increased oxygen concentrations. Additionally, predictive models suggest that achieving desired water quality goals, such as chlorophyll a ≤4 mg m–3 and primary production ≤150 g C m–2 year–1, requires phosphorus concentrations below 10 mg m–3. Therefore, targeting phosphate levels below 50μg L-1 is necessary to restore lakes and prevent further eutrophication.
Does increased rainfall lead to higher leaf nitrogen content?4 answersIncreased rainfall does not consistently lead to higher leaf nitrogen content. The studies by Wang et al. and Shi et al. found that leaf nitrogen content increased significantly with an increase in temperature and rainfall. However, the study by Kwiecinski et al. showed that nitrogen availability and microbial abundance did not respond to the magnitude or frequency of rain events in drylands. Additionally, the study by Barbosa et al. found that changes in water supply and soil nutrient levels did not affect biomass production but did affect leaf-nutrient concentrations, including nitrogen, in savanna seedlings. Finally, the study by Turner et al. demonstrated that while rainfall induced leaf morphological and physiological changes, it did not directly influence leaf carbon isotope discrimination, which is often used as an indicator of rainfall environment. Therefore, the relationship between increased rainfall and leaf nitrogen content is complex and can vary depending on the ecosystem and other environmental factors.
How rainfall impact water quality?4 answersRainfall has a significant impact on water quality. Studies have shown that the water quality of urban lakes is generally worse during the rainy season compared to the dry season, with a decline in dissolved oxygen concentration and an increase in concentrations of ammonia nitrogen, total suspended solids, and total phosphorus. The characteristics of rainfall, such as antecedent dry days, average rainfall intensity, and rainfall duration, have been found to be critical in affecting the concentrations of total suspended solids, total nitrogen, and total phosphorus in stormwater. Extreme rainfall events have been observed to increase the concentrations of cyanide, lead, iron, manganese, total phosphorus, and turbidity in the Dongjiang River, impacting its water quality. These findings highlight the importance of understanding the relationship between rainfall characteristics and water quality for effective water management and pollutant control.
How lakes water level are affected by rainfall in kenya?4 answersThe water levels of lakes in Kenya are affected by rainfall. Studies have shown that there is a correlation between rainfall and the increase in water levels of the lakes. For example, in the Great Rift Valley lakes of Kenya, the recent increases in water levels have been attributed to an increase in mean annual rainfall. Additionally, the Eastern Africa Rift Valley lakes in Kenya have experienced unprecedented lake level changes, which are highly correlated with rainfall records from the Kenya Highlands. The increase in rainfall leads to an increase in the volume of water in the lakes, resulting in higher water levels. This has significant impacts on the local communities and ecosystems surrounding the lakes, including flooding of riparian areas, destruction of infrastructure, and loss of livelihoods.
Precipitation of nitrogen as a cause of eutrophication?5 answersNitrogen deposition from precipitation is a significant cause of eutrophication in various ecosystems, including forests and water bodies. Studies have shown that elevated nitrogen deposition can negatively impact forest bryophyte communities, leading to increased dominance of nitrophilic species and a decrease in species evenness. In the continental United States, climate change-induced precipitation changes are projected to increase riverine total nitrogen loading, exacerbating eutrophication in the Northeast and the corn belt. Wet deposition of anthropogenically derived nutrients, including nitrogen, into water bodies like Lagos Lagoon, contributes to their eutrophication. Similarly, in the Taihu Basin, excessive nitrogen deposition has been found to contribute to water eutrophication, with the deposition load already exceeding the eutrophication critical load. These findings highlight the importance of managing nitrogen deposition to mitigate eutrophication and protect ecosystem health.
What are effects of rainfall on NOx concentration in the air?3 answersRainfall has been found to have an effect on the concentration of NOx in the air. In the Sichuan Basin, continuous rainfall with small-magnitude rainfall has been observed to reduce the concentrations of NOx, along with other air pollutants such as PM2.5, PM10, and SO2. However, the impact of rainfall on NOx concentrations can vary depending on the amount of rainfall and the specific pollutant being studied. In a study conducted in Ahvaz, Iran, it was found that the concentration of NOx pollutants was significantly higher during nonepidemic periods, suggesting a potential relationship between rainfall and NOx concentrations. Overall, the literature suggests that rainfall can have a moderating effect on NOx concentrations in the air, but further research is needed to fully understand the complex relationship between rainfall and air pollution.
