transpiration, as one of the components of hydrological cycle, has not been paid enough attention yet, while it is necessary for sound utilization of rangelands, mostly located in the arid and semiarid regions. the comparison of the different kinds of rangelands species in terms of transpiration rates provides range managers the required information to achieve optimal forage production for a gi...
Tiny airborn particles including those released by human activities and the secondary organic aerosols have potential impacts on the hydrologic cycle. This review briefly introduces the aerosols formation, potential feedback between the aerosols and hydrologic cycle. Recent progress in aerosols, cloud and precipitation is described. The current status using model tools to investigate the intera...
Effective river ecosystem management requires that the existing hydrologic regime be characterized in terms of the natural hydrologic regime and the degree to which the human-altered regime differs from natural conditions. This is known as Range of Variation Approach (RVA) and can be used for variation of stream flow, range of variation and appraisal of dam impacts on riparian zones. In this pa...
With the development of large-scale hydrologic modeling, computational efficiency is becoming more and more important. Rapid modeling and analysis are needed to deal with emergency environmental disasters. The Soil and Water Assessment Tool (SWAT) is a popular hydrologic model, which is less applied in large-scale watershed simulation because of its sequential characteristics. For improving the...
