Simulation of the catchments hydrological processes in arid, semi-arid and semi-humid areas
Hydrological processes and their spatial distribution directly are relevant to climate, topography, geology, and land use in the watershed. Therefore, use of a model whit integrity and high performance for simulating the process in deferent watersheds is very important. In this study was assessment performance of semi-distributed SWAT model in simulating hydrology processes in three watersheds ...
متن کامل1 Groundwater modelling in arid and semi - arid areas : an introduction
Water resources globally face unprecedented challenges, but these are at their greatest in the world’s arid and semi-arid regions. Recent IPCC estimates (Kundzewicz et al., 2007) state that between 1.4 and 2.1 billion people live in areas of water stress; those numbers are expected to increase significantly under the pressures of population growth and climate change. By definition, arid and sem...
متن کاملComparative water economy of sympatric rodents in a Chilean semi-arid habitat.
1. Water requirements, water balance components and dependence on exogenous water were estimated in four species of sympatric rodents inhabiting a Chilean semi-arid region. 2. A significant increase in free water drinking was observed in all rodents when the diet composition was changed from 14 to 20% protein. 3. Under water balance conditions the cricetid species (Phyllotis darwini, Oryzomys l...
متن کاملThe Chilean Way to the Andes: Music, Politics and Otherness
Despite the dominant presence of the Andes Mountains in Chile, the country’s identity as an “Andean” nation, culturally speaking, has never been secure. As a nation ruled by Spanish, British and German descendants, with a majority of the population consisting of creoles and mestizos with no roots in indigenous Andean communities or cultures, “Andean” identity has in fact often been resisted by ...
متن کاملRegional Snowfall Patterns in the High, Arid Andes
Since 1990 the project ‘Climate Change in the Arid Andes’ has been focusing on past climate and environmental conditions in the high mountain range of the north Chilean Andes (18 S– 28 S). The extreme aridity of this region is shown by the absence of glaciers, even at the highest altitudes above 6700 m a.s.l. More knowledge of the present climatic situation is needed to interpret the proxy data...
