Assessment of the Impacts of Climate Change on the Water Allocation, Water Quality and Salmon Production in the San Joaquin River Basin

In this study, we investigated the impact of climate change on streamflow and water quality (TSS, T-N, and T-P loads) in the upper Dong Nai River Basin using the Soil and Water Assessment Tool (SWAT) hydrological model. The calibration and validation results indicated that the SWAT model is a reasonable tool for simulating streamflow and water quality for this basin. Based on the well-calibrated SWAT model, the responses of streamflow, sediment load, and nutrient load to climate change were simulated. Climate change scenarios (RCP 4.5 and RCP 8.5) were developed from five GCM simulations (CanESM2, CNRM-CM5, HadGEM2-AO, IPSL-CM5A-LR, and MPI-ESM-MR) using the delta change method. The results indicated that climate in the study area would become warmer and wetter in the future. Climate change leads to increases in streamflow, sediment load, T-N load, and T-P load. Besides that, the impacts of climate change would exacerbate serious problems related to water shortage in the dry season and soil erosion and degradation in the wet season. In addition, it is indicated that changes in sediment yield and nutrient load due to climate change are larger than the corresponding changes in streamflow.

Impacts Of Climate Change

Traditionally, flood management has concentrated on providing protection against floods using technical measures, but there is currently an international shift towards a more integrated system of flood risk management, whereby flood risk is defined as the probability of flooding multiplied by the potential consequences. Climate change is a great challenge to sustainable development and the Millennium Development Goals (MDGs) in Thailand. The main purpose of this paper is to highlight the challenges associated with the current situation and projected impacts of climate change on the disasters and the human environment in Thailand, to review and explore the potential of Strategic Environmental Assessment (SEA), and to propose SEA in making informed decisions relevant to the implementation of the new adaptation framework in a flood management plan. Thus, current measures on how Thailand is responding to the recent impacts of climate change in river basin planning are presented. It is imperative that an appropriate environmental assessment tool, such as SEA be employed in making rational decisions regarding adaptation frameworks. SEA offers a structured and proactive environmental tool for integrating of climate change adaption into formulating Policies, Plans, and Programs (PPPs) among relevant sectors.
