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...

Using the climate change experiments generated for the Fourth Assessment of the Intergovernmental Panel on Climate Change, this study examines some aspects of the changes in the hydrological cycle that are robust across the models. These responses include the decrease in convective mass fluxes, the increase in horizontal moisture transport, the associated enhancement of the pattern of evaporati...

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...

Groundwater drought is a natural hazard that develops when groundwater systems are affected by climatical drought, when climatical drought occures, first groundwater recharge, later groundwater levels and groundwater discharge decrease. The origin of drought is a deficit in precipitation and that takes place in all the elements that comprise the hydrological cycle (flow in the rivers, soil mois...

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...

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...

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...

Nowadays, there are too many models in the world for simulation of hydrological processes, such as the SWAT physically based model. The SWAT model is a continuous and physically based hydrologic model that is the smallest unit in this model is Hydrologic Response Unit, and all hydrological processes are simulated in each of these units. This model can simulate runoff, sedimentation, erosion and...
