Abstract
The main objective Know the glacier area loss using hydrological and remote sensing
techniques in order to determine their influence on water yield of the basin of the river
Quellcayhuanca using space remote sensing techniques , and evaluate specific year average
rainfall and hydrological characteristics , wet and dry Quellcayhuanca river subbasin.
Evaluate losses glacier area through GIS and Remote Sensing techniques in order to
determine the evolution and glacier retreat rate and determine the water intake for loss of
glacier area using hydrological techniques.
Method was applied GIS, Index Normalized Difference Snow and regional hydrology
yielded information glacial losses.
We determined the evolution of the snow in the period 1987 to 2012, finding that the loss of
snow in this period is 11.80 km2
, representing a loss of 0.50km2
/año
The flow performance variation by snow for dry years 2.2m3
/seg averages.
