The accurate prediction of sand transport rates in the coastal zone depends not only upon the choice of sediment transport model but also, rather critically, upon the formulation used to predict the bed roughness (ks). Sand transport rates are modelled here using both a One-equation, turbulence-closure, TKE-model and also Bijker’s sand transport model. Following some remarks about the nature an...

This study applies some of the most practical longshore sand transport formulations and evaluates their adequacy to estimate the total (suspended and bed load) longshore sediment transport rate (LSTR) at Buarcos Beach, in the West coast of Portugal. The straightforward methodology here present is simple to apply and therefore useful to quickly obtain a first estimate of the littoral transport i...

Background Infertility and fertility decline are quite a conundrum for medicine, rampant among 10-15 percent of couples. In about 40 percent of cases, men are the main culprit. Since sperm production disorders are the focal cause of man infertility, insights into these disorders and taking action to ameliorate the situation is quite vital. The current study concentrates on infertility due to sp...

West Palm Beach (Florida), ISSN 0749-0208. Increasing demands on coastal areas require enhanced understanding of coastal erosion hazards. Here we analyze a 5-km segment of the Kihei coastline (Maui, Hawaii) centered on an area of c...
