abstract shah jahan, based on structural zone is located in south of kapedagh and in eastern side of aladagh mountains in 37◦ till 37◦25' northern latitude and 57◦30' till 58◦30' eastern longitude of northeastern part of iran. geomorphologic and tectonic elements show that this area is partly young and mountains can be affected highly by geomorphologic and hydrologic elem...

Background: The objectives of this study were to establish a swimming capability model for largemouth bass using the FishXing (version 3) program, and to determine the swimming speed and feasibility of fish passage through a waterway tunnel. This modeling aimed to replicate the waterway tunnel connecting the Andong and Imha Reservoirs in South Korea, where there is a concern that largemouth bas...

Salmonid populations of many rivers are rapidly declining. One possible explanation is that habitat fragmentation increases genetic drift and reduces the populations' potential to adapt to changing environmental conditions. We measured the genetic and eco-morphological diversity of brown trout (Salmo trutta) in a Swiss stream system, using multivariate statistics and Bayesian clustering. We fou...

(UMRB) is a major sub-basin of the entire Mississippi River, one of the largest and most diverse ecosystems in North America. The length of the Upper Mississippi River (UMR) is approximately 800 miles (1,287 km). The drainage area of the basin is approximately 189,189 square miles (489,980 km2) and contains about 15 percent of the drainage area of the entire Mississippi River Basin. The Basin i...

Simulation is one of the effective tools for the assessment of waterway designing. The system constitution and procedure of waterway simulation are introduced, and key technologies of waterway simulation system are analyzed, including vessel dynamics modeling, vessel traffic flow modeling, waterway scenery modeling and assessment methods. Moreover, the design the simulation system of inland wat...
