Corner and sloped culvert baffles improve the upstream passage of
Installation of baffles intended to improve fish passage through culverts can reduce discharge capacity and trap debris, increasing flood risk. A sloping upstream face may reduce this risk, but new designs must be tested for fish passage efficiency. The European eel (Anguilla anguilla) is a critically endangered species, yet the suitability of even common baffle types to aid upstream movement h...
متن کاملA synthesized pheromone induces upstream movement in female sea lamprey and summons them into traps.
Female insect pheromone blends induce robust tracking responses in males and direct them into traps. In vertebrates, pheromones that induce strong and precise tracking responses in natural habitats have rarely been described. Here, we show in the sea lamprey (Petromyzon marinus), a vertebrate invader of the Laurential Great Lakes, that a synthesized component of the male mating pheromone, 7alph...
متن کاملExperimental Investigation of Bed Variations due to Circular Culvert Jet with Different Angles
Downfall flows from different outlet hydraulic structures such as culverts and jetsthrowingtothe erodible downstream bed cause scour hole and changes in the downstream bed topography. Therefore,by performing some physical modeling tests on culvert jet flow under different angles, changes in the downstream bed topography under the effect of different parameters such as flow rate, depth of the ta...
متن کاملSpoiler Design
1. Introduction Two primary prerequisites for a safe flight are stability and controllability. In addition, pilot and occupant's comfort is of significant importance which is often referred to as handling qualities. These three aircraft design objectives will influence the design of control surfaces and create variety of design constraints. Flight stability is defined as the inherent tendency o...
متن کاملForecasting flow discharge through time series analysis using SARIMA model for drought conditions, a case study of Jamishan River
Nowadays, water supply is more limited and providing water is more difficult due to increasing population and demand for water. Thus, due to rainfall shortage and impacts of drought, the need for forecasting monthly and annual rainfall and flow discharge through time series analysis is acutely felt. One of the key assumption in time series is their static condition. However, hydrological time s...
