Title: Temperature, Salinity and Circulation in Saudi Coastal Waters (Arabian Gulf) during May 1985 Authors: Din, S H Sharaf El Abstract: Temperature salinity, and current measurements were made hourly at 6 stations in Saudi coastal waters during 19 to 29 May 1985. The surface temperature decreased from Ras Tanura to Manifa and the water mixing off Ras Tanura was higher than in any other region of the Saudi coastal water. Salinity increased from surface to bottom and from Manifa to Ras Tanura. T-S diagram showed 2 distinct water masses at most of the stations. The current measurements showed that the tide-induced current generally tends to flow south through southeastward on flood and west through northwestward on ebb tide. The survey suggests that the general trend of surface circulation pattern along the Saudi coastal waters of the Arabian Gulf is southeastward flow. Page(s): 1-8

Title: Link Node Model for the Simulation of Tides in the Gironde Estuary, France Authors: Unnikrishnan, A S Abstract: Utility of a simplified model such as the link node model in simulating the tides in the Gironde estuary is discussed. In this method, the grid network consists of polygons of variable dimensiOllS whose centres of gravity are called junctions. Any 2 junctions are connected by channel elements. Equations are solved in 1 dimensional form. The 2 dimensional aspects of the flow are represented by virtue of the grid network. Comparison of observed and computed tides and a few other applications are also given. Page(s): 9-13

Title: Salinity and Current Distribution in the Godavari Estuary, East Coast of India Authors: Rao, V Ranga; Ramana, Y V; B S R, Reddy Abstract: Temperature, salinity and current data in the Godavari Estuary for 2 representative months (July and January) are presented. Since the river discharge in July is fairly considerable, the salinity and current distributions are similar to those found in a partly mixed estuary. But in January, as the river discharge becomes negligible, the tidal effect dominates making it a well mixed type of estuary. The continuous current observations at 2 tidal stations reveal that the tidal currents are fairly strong at the mouth (55 cm.sec-1) and decrease upstream away from the mouth. Page(s): 14-18

Title: Physico-Chemical Characteristics of the Mahanadi Estuarine Ecosystem, East Coast of India Authors: Upadhyay, S Abstract: Seasonal pattern of temperature, salinity, pH, dissolved oxygen, phosphate, nitrate and silicate profiles of the Mahanadi estuary have been studied. On the basis of physical characteristics, Mahanadi estuarine system can be classified as a partially mixed coastal plain estuary. The oxygen concentration in this estuarine system is closely related to biological activity and hence to seasonal changes in pH and it bears an inverse relationship with salinity structure. Dissolved nutrients are mostly non-conservative in this estuary. Land runoff coupled with biological and abiological processes appear to have a considerable bearing on the distribution pattern of these micronutrients in this estuarine waters. Page(s): 19-23
