Awareness of the level of river flow and its fluctuations at different times is one of the significant factor to achieve sustainable development for water resource issues. Therefore, the present study two hybrid models, Wavelet- Adaptive Neural Fuzzy Interference System (WANFIS) and Wavelet- Artificial Neural Network (WANN) are used for flow prediction of Gamasyab River (Nahavand, Hamedan, Iran...

We studied how the extensive diversion of Colorado River water, induced by dams and agricultural activities of the last 70 years, affected the growth rates of two abundant bivalve mollusk species (Chione cortezi and Chione fluctifraga) in the northern Gulf of California. Shells alive on the delta today ( Post-dam shells) grow 5.8–27.9% faster than shells alive prior to the construction of dams ...

—Fish larvae were sampled at multiple fixed sites from late winter to early summer over 6 years (1990–1995) in the southern Sacramento–San Joaquin Delta. A total of 394,797 fish larvae representing 15 species or taxonomic groups was collected. The assemblage was numerically dominated by three species that represented 98% of the total catch: alien shimofuri goby Tridentiger bifasciatus (71%), th...

The primary objective of this project was to estimate the nitrate reduction that could be achieved using restored wetlands as nitrogen sinks in tile-drained regions of the upper Mississippi River (UMR) and Ohio River basins. This report provides an assessment of nitrate concentrations and loads across the UMR and Ohio River basins and the mass reduction of nitrate loading that could be achieved...

there has been too much of a one-way flow drift down a river of evidence. researchers from rich countries have produced the primary evidence which they proceed to summarise within reviews. these summaries have directed care worldwide. however, things are changing and the river of evidence can flow in the other direction. the care of women with eclampsia has been changed or refined throughout th...
