Jl. Boeglin et Y. Tardy, CHEMICAL AND MECHANICAL EROSION IN THE UP PER NIGER BASIN (GUINEA, MALI) - HYDROGRAPH SEPARATION OF 4 COMPONENTS, Comptes rendus de l'Academie des sciences. Serie II. Sciences de la terre et des planetes, 325(2), 1997, pp. 125-131
A model for hydrograph separation of four components (deep groundwater
, superficial groundwater, hypodermic runoff and surface runoff) is pr
oposed, using a dense sampling of river waters from the upper Niger ba
sin at the Bamako station (Mali). The composition of each component is
supposed to remain constant, while the four different contributions t
o the total flow are variable during the hydrological cycle. The flow
percentage attributed to each component is calculated point by point,
which requires some hypotheses on the concentrations of the selected t
racers.
