Decision support systems (DSS) have been developed for several areas of watershed and water resource management, but the complexity and focus on specific design tasks of many DSS has limited their applicability. The long-term hydrological impact assessment (L-THIA) web application, a DSS based on an integration of web-based programs, geographic information(More)
Since predicted changes in climate will modify temperature and rainfall patterns, there are concerns about the potential impacts of these changes on agricultural drought and agricultural water resources management. An agricultural drought is influenced by several factors such as rainfall, soil characteristics, crops, and reservoir water supply and may be(More)
BACKGROUNDS/AIMS Hepatocellular carcinoma (HCC) is uncommon in young adults and the prognosis of these patients is still unclear.
