“…Our results suggest that erosion, resulting in an increase of suspended sediment concentrations, significanly affects feeding activity of benthic invertebrates (Aldridge et al 1987;Cline et al 1982;Graham 1990;Krno 2000). We found out a positive correlation between proportion of predators to all the larvae with known feeding ecology and TAM, what is related to increased erosion in disturbed streams.…”

Hydrobiological research of high mountain streams in the High Tatras was carried out in [2009][2010]. We evaluated the influence of windstorm on caddisfly assemblages. To assess the influence of windstorm we focused on river morphology using the RHS method and evaluation of TAM, TOM and BOM (CPOM, FPOM, UFPOM) amount in seven streams. Site 1 was a control and the other six were disturbed by the windstorm in different ways. The most remarkable differences compared to the control site was in feeding structure at sites most affected by erosion. In these streams there was a noticeable dominance of predators from the family Rhyacophilidae (mainly Rhyacophila tristis; sites 3, 4, 5, 6) and a remarkable decrease of passive filter feeders (site 4, 5). Using Spearman coefficient we confirmed a positive correlation between the proportion of predators and amount of TAM caused by erosion of steep deforested slopes of windstorm affected sites. In contrast, we did not observe such an increase in the proportion of predators at site 7, which was affected by both windstorm and subsequently by fire. This might be explained by the shallow vee valley with no observed erosion, where this site is situated. We also found a negative correlation between predators and evenness, indicating unstable community structure clearing succesion in the streams disturbed by erosion, and a negative correlation between passive filter feeders and UFPOM. We found out that overhanging tree boughs and LWD had an influence on species composition. RHS was a useful tool in characterising the influence of hydromorphology on caddisfly assemblages.

“…Influx of dusts automatically enhances turbidity level in water. Turbidity impinges on both the density and metabolism of the plant populations present in stream channels (Wallen, 1951;Aldridge et al, 1987). A study by Clavel and Bouchard (1980) showed that the absorption of light energy by water is proportional to the concentration of suspended sediment.…”

Dwarka River basin (3882.71 km 2 ) of Eastern India in the Chotonagpur Plateau and Gangetic Plain is highly affected by stone mining and crushing generated dust. In the middle catchment of this basin, there are 239 stone mines and 982 stone crushing units. These produce approximately 258120 tons of dust every year and this dust enters into the river and coats the leaves of plants. On the one hand, this is aggrading in the stream bed, increasing sediment load, decreasing water quality, specifically increasing total dissolved solid, pH, water colour, and it also degrades the vegetation quality. Vegetation quality is also degraded as indicated by decreasing of NDVI values (maximum NDVI in 1990 was 0.70 and in 2016 it was 0.48). Considering all these issues, the present paper intends to identify dust vulnerable zones based on six major driving parameters and the impact of the dust on river morphology, water quality and vegetation quality in different vulnerable zones. Weighted linear combination method (in Arc Gis environment) is used for compositing the selected parameters and deriving vulnerable zones. Weight to the each parameter is assigned based on analytic hierarchy process, a semi quantitative method. According to the results, 579.64 km 2 (14.93%) of the catchment area is very highly vulnerable: Here 581 rivers have a length of 713 km and these riversare prone to high dust deposition, increased sediment load and water quality deterioration.

“…Inorganic turbidity presents a wide range of problems, particularly for filter feeding organisms. The harmful effects on suspension-feeding bivalves include gill tissue fouling, increased pseudofaecal production [18], decline of ingestion rate resulted from reduction of clearance rate [3], depressed growth rates through overloading the gut and gills with inorganic solids [4,12], reduced metabolic rates and feeding efficiency [1]. Respiration rates are significantly affected by acclimation temperature and turbidity [2,14]).…”

The dynamics of suspended sediment and the impact on a lake-inhabiting bivalve were studied in the Abashiri River basin, in eastern Hokkaido, northern Japan. The Japanese bivalve: Corbicula japonica is the most important fishery resource in Abashiri Lake. Torrential rain over 80 mm per day resulted in considerable sediment concentration during the summer of 2003. Suspended sediment (SS) concentrations >1600 mg/l were measured in the tributaries, where fragile rock formations and faults had developed. The factors influencing SS concentration were analyzed by multiple regression analysis. This led to the identification of soft bedrock and fault densities as significant factors influencing sediment concentration. Fine-sediment particles less than 0.063 mm in diameter accounted for more than 80% of the samples at all stations. Since the lake bivalve prefers coarse substrates, a negative relationship was observed between the percent of fine sediment and the C. japonica distribution and fatness. The substrate around the mouth of the river was also composed of fine sediment, which indicated that the suspended sediment produced from the mountain tributaries has deteriorated the lake environment, especially for C. japonica survival and growth.
