Understanding recruitment and identifying factors critical to that process are imperative if adult spiny lobster Panulirus argus stocks are to be conserved and properly managed. The goal of our research has been to obtain ecological infonnation linking inshore postlarval spiny lobster recruiunent to later life stages, lhereby providing the basic framework for assessing and predicting adult stoc...

During an expedition in 2014 in the Gulf of Gabes that aimed to evaluate the impact of the pollution of the phosphate industry on the marine environment, numerous dead coral fragments were retrieved from several stations along a 18 km long transect in front of the industry complex of Gabes. Detailed taxonomy of these coral fragments shows clearly that all fragments belong to the species Cladoco...

Ground penetrating radar (GPR) is a commonly-used geophysical technique, yet the use of water-penetrating (WPR) has been less-well researched and published on. This surprising, given wide GPR on ice success early aquatic experiments in 1970s 1980s. The past 15 years have seen advances modes antenna deployment, understanding limiting environmental conditions applications to geotechnical engineer...

This study aims to analyze changes in the morphometry of lake bottom a period ten years, namely from 2006 2016. The analysis morphometric is carried out by comparing two bathymetric maps mapping and aspects studied include water surface area stated km 2 , volume (in m 3 ) depth m). results showed that within 10 years has decreased 1.03 while total increased 10.41 . average barely changed signif...

For efficient use of water, accurate measurement of flow in (field/laboratory) channels is required for many water resource projects. The present work is aimed to study the flow characteristics of a twin plate weir (two sharp-crested plates are placed one behind the other at some distance) under free and submerged flow conditions. Experiments are performed with four spacing of the twin plate we...

Abstract In areas with a pronounced relief, water erosion causes great harm to agriculture and other sectors of the national economy. It leads destruction soil cover, reduction in area arable land, decrease fertility, removal products into floodplains, siltation ponds rivers road network. The scientific goal was identify influence main natural factors (snow reserves, freezing moisture) on forma...
