Abstract

Water parameters of East Hammar marshland were measured during July 2006 in several sites .Spatial and temporal variations existed between the six sites sampled. Water temperature , salinity, conductivity ,total dissolved solids (TDS) and pH values were higher in flood tide ,on contrary dissolved oxygen, oxidation and reduction optional ( ORP )and flow rate were higher during ebb tide . Values of air ;water temperatures ,Salinity,conductivity ,TDS and pH showed increasing trend as time progressing toward mid day, others decrease like dissolved oxygen ,ORP and transparency . Flow rate was faster during ebb than flood. Water level increased with flood tide. Time of the day and tidal stage have pronounced effect on several water parameters and must betaken in consideration during sampling.
