| 内容記述 | One perspective of global warming we are keenly interested in is spatial and temporal variation of precipitation and its subsequent impact on water resources utilization. This report summarizes the outcomes of our intensive investigation for research institutes and universities that have been carrying out advanced studies of the assessment of potential impacts of global warming on water resources utilization. Here, we present 2 aspects of impact assessment studies on water resources for irrigated agriculture. Many researches are carried out to estimate potential changes in water availabilities and/or river discharges by applying projected climatic data for forced input to various types of rainfall-runoff models. Compared to the assessment of hydrological characteristics variations, fewer attempts were made to perform impact assessment of water resources, especially that of agricultural water. Potential water stresses were estimated in the framework of grid-based distributed water circulation models, in which water availability and demand are roughly compared in large-scale grids on the order of 10~100km. However, in mid- and small-scale basins, where we carry out impact assessment studies on the order of 1~10km, we need schemes to estimate the irrigation intake and its allocation, because agricultural water is highly dependent on human decision making processes such as water management. In addition, we need distributed water circulation models which provide river discharges at any point and time of interest to us, and the spatial dynamics of actual evapotranspiration and soil moisture content, because agricultural water intake points and irrigated agricultural area are spread over basins. In previous attempts, most of the optimization procedures, mainly for lumped models, were developed to obtain the optimal parameter which will improve the accuracy of the discharges at the outlet of target basins. Therefore, new approaches in parameter optimization strategies for distributed water circulation models are required to obtain optimal parameter sets. |
