Dataset description

DigiBog_Hydro is a hydrodynamics model that is usually being used to model water-table dynamics in peatlands. We modelled drained tropical peatlands, typical of those found in Sebangau, Kalimantan, Indonesia. The modelled scenarios counted in several items: degree of peatland degradation, climate, ditch dam and bund existence, and bund depth. The degree of peatland degradation had two variants, which were moderately degraded (Mod-Dgr) and severely degraded (Sev-Dgr) peatlands. Three years with different climate conditions were simulated, which were a La Niña year (LaN) (1 February 2011 to 8 February 2012), an ENSO ‘Neutral’ year (Ntr) (1 February 2013 to 8 February 2014), and a El Niño year (ElN) (1 February 2015 to 8 February 2016). The ditch dam and bund existence variations were a drained peatland with ditch dams and bunds (Combined), a drained peatland with bunds but without dams (Bunded), a drained peatland with dams but without bunds (Dammed), and a drained peatland without dams and without bunds (Control). In the scenarios that involve bunds, two bunds variants were used, which were On-Surface (Os) and Extended (Ex). The DigiBog _Hydro model was supplied with net rainfall data, accompanied with hydraulic conductivity and specific yield data that were vary in the x-y plane and in depth. The model was also provided with initial and boundary condition data. The main model settings were stored in parameter and column status files. The outputs of DigiBog_Hydro were peatland water-table variations at a certain interval within the simulated period.
