the genus alburnoides jeitteles, 1861 in iran is reviewed, and diagnoses are presented for all eight recognized species. alburnoides eichwaldii, a. holciki, a. idignensis, a. namaki, a. nicolausi, a. petrubanarescui, a. qanati and a. tabarestanensis are considered valid and three new species are described: alburnoides coadi sp. n., from namrud river in kavir basin, a. parhami sp. n., from atrak...

The study site is located in an environmentally protected area known as an "APA" in São Pedro and Analândia, State of São Paulo, southeastern Brazil, whose watercourses are under strong anthropogenic pressure. Two basins were studied (sub-basin of the Corumbataí River and basin of the Jacaré-pepira River) with the purpose of characterizing the ichthyofauna of various streams, comparing fish div...

Floodplains and river corridor wetlands may be effectively managed for reducing nutrients and carbon. However, our understanding is limited to the reduction potential of these natural riverine systems. This study utilized the long-term (1978–2004) river discharge and water quality records from an upriver and a downriver location of the Atchafalaya River to quantify the inflow, outflow, and infl...

The Bolivian Andes flank one of Earth’s major topographic features and dominate sediment input into the Amazon Basin. Millennial-scale erosion rates and dominant controls on erosion patterns in this range are poorly known. To define these patterns, we present 48 erosion rate estimates, derived from analysis of in situ Be in quartz-bearing alluvium collected from the Upper Beni River basin. Eros...

Long-term streamflow data are vital for analysis of hydrological droughts. Using an artificial neural network (ANN) model and nine tree-ring indices, this study reconstructed the annual streamflow of the Sacramento River for the period from 1560 to 1871. Using the reconstructed streamflow data, the copula method was used for bivariate drought analysis, deriving a hydrological drought return per...

Despite obvious limitations, such simple indices can reveal important features of streamflow and how they compare with those of other streams in the same basin. These simple indices can also give clues regarding the timing of historic, momentous events, such as the abrupt decrease of the monthly maximum flow in the Little Red River record (1%1) shown in Figure 1 with records of other selected s...

Sediment management nowadays is often concerned around sediments that have been polluted in former times, posing the following questions: what risks remain after time has passed concerning the persistence, ageing and bioavailability of the polluting substances; where does the risk apply regarding the transport of contaminated sediments and the management objectives in the different zones of a r...

Hydrological components in a river basin can get adversely affected by climate change in coming future. Manipur River basin lies in the extreme northeast region of India nestled in the lesser Himalayan ranges and it is under severe pressure from anthropogenic and natural factors. Basin is un-gauged as it lies in remote location and suffering from large data scarcity. This paper explores the imp...

Shaping global change adaptation strategy in water resource systems requires an interdisciplinary approachto deal with the multiple dimensions of the problem. The modelling framework presented integrates climate, economic, agronomic and hydrological scenarios to design a programme of adaptation measures at the river basin scale. Future demand scenarios, combined with a down-scaled climate scena...

The application of systems analysis techniques in evaluating project alternatives having more than one objective in river basin planning for the sustainable development is of recent origin. This paper presents the planning under fuzzy environment including both qualitative and quantitative aspects for the sustainable development of a major peninsular river basin (Krishna River Basin) in souther...
