文摘

As Singapore's only remaining patch of primary freshwater swamp forest, the conservation of the Nee Soon Swamp Forest (NSSF) is of utmost importance if a large proportion of the flora and fauna in Singapore is to be conserved. An integrated hydrological model for the NSSF is developed, with the objectives to numerically model the hydrological variations, to assess the impact of future climate change as well as to facilitate future eco-hydrology management. The numerical model considers the hydrological processes in a holistic manner, which includes the rainfall-runoff, the evapotranspiration, and the interactions between surface water and groundwater etc. Due to the constraints imposed from setting up monitoring stations in the protected forest, a combined approach is adopted to develop the numerical model which makes use of the field survey data and the alternative remote sensing data. With the climate projection inputs from the Regional Climate Model (RCM), the numerical model is applied to run future scenarios to assess the climate change impact. A few management strategies are also proposed in order to maintain favourable hydrological conditions for conserving the local ecosystem.
