| Abstract |
A review of estimates of the river discharge of dissolved constituents indicates that, despite recent improvements in the data base, information remains inadequate for the accurate estimation of riverborne of many important constituents. The limitations of estimates of mean annual loads of suspended sediment are also discussed. Contemporary changes in land use and river management can have major influences on river discharges, particularly on the fluxes of suspended sediment to estuaries. For the estuarine environment key questions arise conccerning (i) interactions between particles and dissolved constituents and their consequences for the modification of fluxes of the latter to the ocean (ii) chemical speciation, (iii) flocculation of particles and the characteristics of colloids. These are related topics are discussed and recommendations made regarding research objectives. |
