During floods, sediments are transported from watersheds into reservoirs, slowly decreasing water volumes and this leading to economic losses. Thus, in the long term, sedimentation endangers reservoirs’ sustainability. Sediments can also block low-level hydraulic structures such as bottom outlets and powerhouse intakes and cause abrasion of gates and turbines. Additionally, the trapped sediment...

The Densu River Basin has come under serious threat from a number of human activities such as farming, lumbering, sand winning, animal grazing, dam construction among others. These activities have significant implications on the fluvial processes of the river such as erosion, braiding and flooding. The study examined the current fluvial processes and landforms and the dynamics in the river morp...

Spring development of diatoms in Ford Lake, Michigan, USA was markedly different in 2004 from 2005 and 2006. In 2004, diatom biovolume surpassed 15 mm(3)l(-1) but in 2005 and 2006 maximum biovolume was less than 5 mm(3)l(-1). Soluble reactive silica (SRSi) in 2004 fell below 5 microM whereas in 2005 and 2006, SRSi remained above 30 microM. Taxonomic composition was similar among years and consi...

This study was carried out to determine the fish fauna of Kuzgun Dam Lake dranaige. Eight (Barbus lacerta, Capoeta damascina, Alburnus sellal, Alburnoides velioglui, Squalius semae, Oxynoemacheilus araxensis, O. bergianus and Salmo euphrataeus) species belonging 4 families (Cyprinidae, Leuciscidae, Nemachelidae Salmonidae) were determined.

The construction of large dams has been shown to increase the prevalence and intensity of human schistosomiasis. However, until now no study had been carried out to assess the impact of such a project in Côte d'Ivoire. For Kossou and Taabo, two large dams which became operational in the 1970s, baseline data are available on schistosomiasis prevalence in the surrounding area before dam construct...

Abstract Human-induced water level fluctuations (WLFs) are among the major pressures threatening lake ecosystems. Their effect on meiobenthic species of littoral zone has been poorly investigated. In this study, we aimed at assessing effects human-induced WLFs composition and functionality benthic copepod assemblages Lake Maggiore, Italy Switzerland. From 1942 to present, Maggiore regulated thr...

Riparian habitat makes up a small fraction of the landscape but provides important stopover habitat for migratory birds. Hydroelectric dam operations cause fluctuations in water levels that can change the amount or quality of riparian habitat, which in turn might affect potential fattening rates of migrant birds. Here we used plasma metabolite analysis to estimate variation in fattening rate in...

The aim of the present study was shedding light on disease factors underlying mortality event among common carps inhabiting Hirfanlı Dam Lake in Türkiye spring year 2021. For this purpose various parasitological, bacteriological and virological research techniques were employed. Five parasite genera, Dactylogyrus spp., Myxobolus Eimeria Trichodina Diplostomum spp. isolated from 13 carps. opport...
