We present a study of the physical characteristics traveling waves at shallow and intermediate water depths. The main subject is to influence nonlinearity on dispersion properties waves, their limiting heights steepness, shape solitary etc. A fully nonlinear Serre–Green–Naghdi-type model, classical weakly Boussinesq model fifth-order Stokes wave solutions were chosen as models for comparison. a...
Purpose: Given that physical activity is the most important environmental moderating factor, it has been known as an effective, available, low-cost and non-pharmacological approach to increase or maintain bone density at different ages. The purpose of this study was to investigate the effect of 12 weeks of training in water, on land and combined environment on bone mineral density in premenopau...
Establishing the origin of water D/H ratio in Solar System is central to our understanding chemical trail during star and planet formation process. Recent modeling suggests that comparisons D$_2$O/HDO HDO/H$_2$O ratios are a powerful way trace evolution and, particular, determine whether inherited from molecular cloud or established locally. We seek D$_2$O column density derive warm region towa...
with industrial and economic growth and different material production that humans gained from natural resources for their comfort and walfare, inwardly introduced toxic material and heavy metal entered environment that there created serious problems for themselves and environment. This study accomplished to determine heavy metal concentration (As, Ba, Cd, Hg, Pb, Cr)in water resources and river...
The theme for the papers in the issue is “Hydrology and the Environment”. There is a mix of review papers and research papers. Climate change and water are very important subjects in these times. Hydrology is the science of water, and the environment has water as one of the three principal earthly components, the other two being the air and the earth. Hence, hydrology and the environment would ...
