Individual and Coupled Effects of Future Climate and Land Use Scenarios on Water Balance Components in an Australian Catchment

چکیده
Assessing the impacts of both climate and land use changes on hydrologic variables is crucial for sustainable development water resources natural ecosystems. We conducted a case study catchment in southwestern Australia to assess future changes, separately combination, resource availability. For this evaluation, Soil Water Assessment Tool (SWAT) model was first calibrated then forced by 34 global models (GCMs), under two Representative Concentration Pathways (RCP4.5 RCP8.5) five scenarios (LU0–4). Our results suggested that SWAT reproduced observed monthly streamflow well. Land have all variables, especially runoff at annual scale. Future projected decrease seasons, winter spring. combined effects LU1–4 were only slightly different from response LU0. An uncertainty analysis shows GCMs had greatest contribution followed RCPs scenarios. Hence, it advisable an ensemble minimize variables.

It has been reported that in different regions and sowing dates, the response of crops to past climate change is not the same, due to different rates of decrease/increase in each climatic variable at different regions and months of year. This study was aimed to assess the effect of individual versus simultaneous changes in solar radiation (S), precipitation (P) and temperature (T) on rainf...
