Integrated assessment of climate change, climate input errors and land-use change on soil-moisture and carbon-balance in a catchment simulation framework

Assessing soil moisture and carbon balance changes in a warmer climate is important for land-use and agricultural planning. A decision support tool is proposed that performs the assessment and allows us to develop plans that reduce adverse impacts. The tool consists of three parts. The first part models changes in rainfall accuracy to calibrate approaches for catchment simulation. The second part simulates rainfall under climate change conditions using stochastic downscaling. The third part simulates future soil moisture and carbon balance using downscaled climate inputs. The end result is a probabilistic simulation of the catchment hydrology under future climates.
