Binwa is a perennial hill stream of the Western Himalayan region of Himachal Pradesh. During the present investigation, four observation sites based on altitudinal differences were selected, i.e., Kharli(S1), Baijnath (S2), near Chobin (S3), and Triveni (S4) and water samples were analyzed for physico-chemical and biological parameters for one year (Mar.2011-Feb.2012). Water temperature, water current, dissolved oxygen, turbidity, T.D.S., electric conductivity, total Hardness, phosphate, and nitrate had played an essential role in determining the variations in planktonic and macroinvertebrate fauna of the stream.Species diversity indices such as Simpson, Shannon and Wiener, and Margalef’s diversity index of macroinvertebrates were worked out for all the observation sites. Based on the comparison of physico-chemical parameters of water samples with different standards prescribed for drinking water, water quality index for four stations calculated. Similarly, EPT taxa (Ephemeroptera, Plecoptera, Trichoptera) measured, and EPT index computed. The water quality of the stream deteriorates downstream from head to mouth due to different types of anthropogenic interferences. The findings revealed that stream has no pollution at S1, while it is oligotrophic from S2 to S3 and meso-oligotrophic at S4.

In order to study the effects of the newly-built ecological spur dikes on spring phytoplankton in Wangyu River, a riverway of water diversion project from Yangtze River to Taihu Lake, triple samplings were carried out in eleven sites from the near and upper water around the ecological spur dikes in April and May, 2011. The samples were collected to investigate the species and density of phytoplankton. Meanwhile, some environmental factors, such as temperature, pH, total nitrogen (TN), total phosphorus (TP) were determined. Indices of Simpson (D), Shannon-Wiener (H), Pielou (J) and Margalef (Dm) were used to analyze the change regulations of phytoplankton diversity. H, J, Dm were also used to evaluated the water quality, and they were 2.873, 0.532, 3.037. The results indicated that the composition of phytoplankton species was similar to the typical character of large or medium rivers. Based on the diversity indices, higher biological plankton diversity and better water quality emerged near the dikes. Results of this research supplied a theory for building ecological spur dikes to improve water quality of large or medium rivers and also provided a basis of using phytoplankton to monitor changes of water quality.

The study aimed to evaluate water quality at Bung Binh Thien Lake, An Giang Province, Vietnam using Shannon-Wiener species diversity index (H’) and associated average score per taxon (ASPT) calculated from composition of phytoplankton and zoobenthos. The water quality index (WQI) was used as the reference for the quality of surface water. The samples of surface water quality, phytoplankton, and zoobenthos were simultaneously collected at 11 sites in the dry season. The results showed that WQI (57-88) classified water quality from good to medium, H’ calculated using phytoplankton species (1.12-2.71) presented water quality from medium to bad whereas, (H'z) calculated (0 to 2.07) and ASPT (2-4.21) calculated from zoobenthos species divided water quality from bad to very bad. The findings revealed that assessing water quality should not totally only relied on diversity indices (H’, ASPT) but also carefully consider compositions of phytoplankton and zooplankton. In addition, interpretation of the biodiversity indices for water quality examination should involve the experts in the relevant fields. Nghiên cứu nhằm đánh giá chất lượng nước tại hồ Bung Binh Thiên, tỉnh An Giang, Việt Nam sử dụng chỉ số đa dạng loài Shannon-Wiener (H’) và chỉ số tính điểm trung bình bình theo họ (ASPT) được tính từ thành phần của phiêu sinh thực vật và động vật đáy. Chỉ số chất lượng nước (WQI) được sử dụng tham chiếu cho chất lượng nước mặt. Các mẫu chất lượng nước mặt, phiêu sinh thực vật thực vật và động vật đáy được thu đồng thời tại 11 địa điểm trong mùa khô. Kết quả cho thấy WQI (57-88) phân loại chất lượng nước từ tốt đến trung bình, H’p được tính dựa vào các loài phiêu sinh thực vật (1.12-2.71) thể hiện chất lượng nước từ trung bình đến xấu trong khi, H’z (0- 2.07 ) và ASPT (2-4,21) được tính toán từ các loài động vật đáy phân loại chất lượng nước từ xấu đến rất xấu Kết quả nghiên cứu cho thấy đánh giá chất lượng nước không chỉ hoàn toàn dựa vào các chỉ số đa dạng (H’, ASPT) mà còn xem xét cẩn thận thành phần loài của phiêu sinh thực vật và động vật đáy. Ngoài ra, việc giải thích các chỉ số đa dạng sinh học nhằm tra chất lượng nước cần có sự tham gia của các chuyên gia trong các lĩnh vực liên quan.

Rivers protection is fundamental for the socioecological systems, and the benthic macroinvertebrates communities can be used to assess the quality of river waters. This study aimed to assess the water quality at the “Cachoeira do Paraíso” waterfall, Peruíbe, SP, based on the benthic macrofauna. Sampling took place at 3 sampling sites, under different levels of anthropic influence. Water physical-chemical and sedimentological parameters were evaluated, as well as macrobenthic organisms. Samplings were done by kick sampling technique. The organisms were identified at the lowest possible taxonomic level and points were attributed to each group according to their respective sensitivity and tolerance to pollutants. Then, a biological index was calculated to indicate the water quality. Ecological indices were calculated and compared using ANOVA. The water physical-chemical parameters showed to be within the legal standards. 13 taxonomic groups of benthic macroinvertebrates were identified, with the Shannon diversity indices indicating similar taxonomic diversity. The score given to each taxa generated biological indices for each sample, ranging from regular to excellent. Diptera (with head) I was the most representative taxon, and sensitive taxonomic groups, were found in all the sampling sites, suggesting a good quality of the water body during the period of study.

Stream Quality

The use of macroinvertebrates as indicator organisms is cheap, easy, and a reliable way to determine water quality. To determine the effects on man-made structures on macroinvertebrate communities and stream quality, comparisons were made between macroinvertebrate samples from established open canopy upstream and forested downstream reaches, and adjacent reaches with man-made structures (road bridge and foot bridge). Macroinvertebrates were collected using a D-frame kicknet, following Illinois Riverwatch protocol. There was little difference in Macroinvertebrate Biotic Indices and Shannon Diversity Indices between established and adjacent reaches. However, there were significant differences between EPT/non-EPT and pollution intolerant/tolerant organisms found between all reaches, and between all paired comparisons of the established and adjacent reaches (p< 0.05), except when comparing the forested reach with the road bridge reach (EPT/non-EPT, p=0.583; pollution intolerant/tolerant, p=0.542), the forested reach and the road bridge (EPT/non-EPT, p=0.84), and the forested reach with the adjacent foot bridge reach (EPT/non-EPT, p=0.489). Noticeable differences in taxa distribution occurred between all reaches. Different samples obtained from different reaches indicated varying distribution of taxa, with the forested reach having more high quality EPT taxa and individuals, however all reaches displayed similar water quality of “fair”, with little impact from man-made structures.
