Abstract

Estimation of rivers dissolved and suspended loads interpolating methods - accuracy and precision A. Toma, P. Hubert, M. Meybeck Centre d'Informatique Geologique de VEcole des Mines de Paris, 35 rue St. Honor e, 77305 Fontainebleau, France 1.Introduction Mass budgets of chemical species or suspended sediments are often needed in hydrology The importance of computing mass budgets is detailed in ( OKane*; Meybeck"; Bellamie et al.'; Walling^; Littlewood?)- Without enter- ing into details we can name some domains where the knowlege of mass budgets and their confidence limits is usefull: - River, lake and marine eutrophisation, ecological modelling and corre- sponding decision making ( P, N, SiCb) - Erosion and sedimentation phenomena ( suspended sediments) - Assessment and quantification of long term trends Typically, daily water discharge and sparse concentration data are available. According to Walling^ or Littlewood\ three types of methods are desc
