2015 Aquatic Sciences Meeting
Aquatic Sciences: Global And Regional Perspectives — North Meets South
22-27 February 2015
Recent research shows inland water may play some role in continental carbon cycling though its contribution has remained uncertain due to a shortage of data (Battin et al., 2009). The author has developed process-based National Integrated Catchment-based Eco-hydrology (NICE) model (Nakayama, 2008a-b, 2010, 2011a-b, 2012a-c, 2013; Nakayama and Fujita, 2010; Nakayama and Hashimoto, 2011; Nakayama and Shankman, 2013a-b; Nakayama and Watanabe, 2004, 2006, 2008a-b; Nakayama et al., 2006, 2007, 2010, 2012), which incorporates surface-groundwater interactions, includes up- and down-scaling between various scales, and can simulate feedback between hydrologic-geomorphic-ecological processes. Here, NICE was applied to various catchments and expanded to evaluate global eco-hydrological process. The simulated result agreed reasonably with that in the previous research (Fan et al., 2013) and extended to clarify dynamic eco-hydrological process. NICE was further developed to incorporate biogeochemical cycle including reaction between inorganic and organic carbons in terrestrial and aquatic ecosystems. This advanced eco-hydrologic and biogeochemical coupling model would play important role on identification of greenhouse gas balance of biosphere and boundless biogeochemical cycle along terrestrial-aquatic continuum (Cole et al., 2007; Battin et al., 2009).
