What about landsat LDCM for water resources?


A new Landsat satellite was launched one Monday (Feb. 11, 2013) from the Vanderberg Air Force Base in California. The LDCM or Landsat Data Continuity Mission joined the 15-year-old Landsat 7 and the 30-year-old Landsat 5. Since satellites are attracted by earth gravity, the launch of new satellites is important to preserve the continuity of the image registration.



Main factors affecting groundwater regime

The concept of a groundwater regime is based on the fact that the occurrence and distribution of groundwater is not merely a product of chance, but the result of a combination of climatic, hydrologic, geologic, topographic and soil-forming factors that together form an integrated dynamic system. These factors are interrelated in such a way that each provides some insight into the functioning of the total system and thus serves as an indicator of local conditions of groundwater occurrence and distribution (PAEL, 1993).



Climate change impact on watershed response

Mathematical models of global climate can reproduce many aspects of the physical climate system. General Circulation Models (GCMs) simulate physical processes in the atmosphere, ocean, cryosphere, and on the land surface. Predictive scenarios on climate change will be applied to selected GCM models and their output will be used on the PRMS hydrologic simulations.
