In the distributed hydrological simulations for complex mountain areas, large amounts of meteorological input parameters with high spatial and temporal resolutions are necessary. However, the extreme scarcity and uneven distribution of the traditional meteorological observation stations in cold and arid regions of Northwest China makes it very difficult in meeting the requirements of hydrologic...

In recent years, the population size and scale of the Shiyang River Basin unceasingly expanding lead to a series of ecological environment: surface water reducing, land desertification and Ground water levels fall, etc. Research evolution characteristics of population distribution and migration growth of Shiyang River Basin contribute to river water resources and the industrial development of t...

Under a specific tectonic background, the change in paleoclimate can show different facies associations and depositional architecture. The Jurassic China continent was an important region for transforming Paleotethys domain to circum-Pacific domain, its information entirely preserved continental sedimentary successions. Middle Zhiluo Formation, Ordos Basin, at just critical period of paleostruc...

27 We investigate the interannual variability over 2003-2007 of different hydrological parameters in 28 the Amazon river basin: vertically-integrated water storage from the GRACE space gravimetry 29 mission, surface water level over the Amazon River and its tributaries from in situ gauges, and 30 precipitation. We analyze the spatio-temporal evolution of total water storage from GRACE and 31 in...

Seven models commonly used to estimate the daily reference evapotranspiration (ET0) were evaluated in the middle Heihe River Basin of the arid northwestern part of China. The objectives of the study are to choose the appropriate model for estimating the areal distribution of ET0 and to explain the spatial–temporal distribution of the same through GIS in the study area. The results indicated tha...

distribution of the genus chondrostoma in iran, which is mostly known from the caspian sea, tigris river, kor river and esfahan basins was mapped. the kura nase, chondrostoma cyri is reported from armenia, georgia and iran and it is found in the streams and rivers draining to the western coast of the caspian sea from the kuma river in the north southward to the kura and aras river basins in the...

[1] Intensification of the Arctic hydrologic cycle and permafrost melt is expected as concentrations of atmospheric greenhouse gases increase. Quantifying hydrologic cycle change is difficult in remote northern regions; however, monitoring the stable isotopic composition of water runoff from Arctic rivers provides a means to investigate integrated basin-scale changes. We measured river water an...

[1] A salient characteristic of river discharge is its temporal variability. The time series of flow at a point on a river can be viewed as the superposition of a smooth seasonal cycle and an irregular, random variation. Viewing the random component in the spectral domain facilitates both its characterization and an interpretation of its major physical controls from a global perspective. The po...
