Valeur et repartition de la dissolution specifique dans les karsts des montagnes Nakanai
Abstract:
Hydrochemical research has been carried out in Nakanai Mountains, a karst system located in the tropical wet areaThree types of water feed the underground karst: the first is diffuse seepage across thick soil and forest cover, which is generally supersaturated, producing flowstone deposition in conduits located close to the surfaceThe second is open joints, which allow the introduction of higher seepage discharge, this can be more aggressiveThis diffuse input constitutes the base flowThe third occurs during rainfall, when ephemeral gullies begin to be active, bringing high discharge of aggressive waterDuring high water, solution load tends to decrease, according to dilutionMost of the evolution of deep karst drainage system depends on this type of ephemeral inputMean solution load of underground streams tends to decrease with altitude, as shown by progressive disappearing of calcite deposition in the riverbedAccording to the estimated data (12 m annual rainfall, solute load), karst denudation rate seems to reach about 400 m3 / km2 / year, that is close to the highest world standardNevertheless, this value is lower than estimated before, taking into account the lowering of the solution load with altitude and during high water
