Comparison of GPP and Hydrological Organic Carbon Flux

A Catchment Scale Approach

• Broschiertes Buch

Produktbeschreibung

This book presents a catchment scale case study
investigation into the export of organic carbon
through a river system in comparison with carbon
that is produced by vegetation through
photosynthesis. The research discusses the use of a
hydrological simulation model to analyse
organic carbon samples from stream and tributaries.
The gross primary productivity of the vegetation
cover in the catchment was estimated using a
radiation use efficiency model driven by MODIS
TERRA data on vegetation greenness and modeled
surface irradiance. The relationship between total
organic carbon discharged in-stream and total
carbon uptake by plants was assessed using a cross-
correlation analysis. The results of the hydrologic
modeling approach and terrestrial GPP outcome were
compared. This comparison revealed the likely
proportion of catchment GPP that contributes
to in-stream hydrological flux of organic carbon.
Total Organic Carbon Load was 0.45% of GPP. As a
result, it can be concluded that the hydrological
flux of organic carbon in a forested catchment is a
function of gross primary productivity.
