one of the main components affecting the ecohydrology is interception or loss of rainfall by plant canopy. interception of reduced effective precipitation and dry areas to prevent soil moisture. low level of abstraction is considered as important factors in managing rangeland resources. in this study, the vegetative form, some broad-leaved plants and plant selection and method of abstraction in...
Abstract The sixth Intergovernmental Panel on Climate Change (IPCC) assessment report confirms that global warming drives widespread changes in the terrestrial hydrological cycle, and are regionally diverse. However, reported trends cycle suffer from significant inconsistencies. This is associated with lack of a rigorous observationally-based simultaneous different components cycle. Here, we re...
The present study evaluates the reproducibility of the climatological seasonal cycles of three hydrological variables, soil moisture, river discharge and terrestrial water storage in the Japan Meteorological Agency Land Data Analysis (LDA) by means of a system consisting of the LDA and a global river-routing model (LDAG). LDAG satisfactorily reproduces the seasonal cycle of soil moisture at mos...
The natural environment and livelihoods in the Lower Mekong Basin (LMB) are significantly affected by the annual hydrological cycle. Monitoring of soil moisture as a key variable in the hydrological cycle is of great interest in a number of Hydrological and agricultural applications. In this study we evaluated the quality and spatiotemporal variability of the soil moisture product retrieved fro...
Coal mining is one of the core industries that contribute to the economic development of a country but deteriorate the environment. Being the primary source of energy, coal has become essential to meet the energy demand of a country. It is excavated by both opencast and underground mining methods and affects the environment, especially hydrological cycle, by discharging huge amounts of mine wat...
We present the construction of a dynamic area fraction model (DAFM), representing a new class of models for an earth-like planet. The model presented here has no spatial dimensions, but contains coupled parameterizations for all the major components of the hydrological cycle involving liquid, solid and vapor phases. We investigate the nature of feedback processes with this model in regulating E...
Humans directly change the dynamics of the water cycle through dams constructed for water storage, and through water withdrawals for industrial, agricultural, or domestic purposes. Climate change is expected to additionally affect water supply and demand. Here, analyses of climate change and direct human impacts on the terrestrial water cycle are presented and compared using a multimodel approa...
