The knowledge of actual water use for different land uses particularly for
agricultural crops is considered as one of the major factors for water resource
planning and irrigation water management. However, actual water use of a land
use is mainly determined by its actual evapotranspiration (ET ). In recent times,
with the advent of new satellite technology, spatio-temporal evapotranspiration
can be measured from remotely sensed surface temperature using various surface
energy balance algorithms.In this study, SEBAL (Surface Energy Balance
Algorithm for Land) techniquehas been used to measure the spatial variation of
actual evapotranspiration (ET ) from Landsat 5 image prevailing in the Doon
Valley, Uttarakhand, India. This particular method utilizes the combination of
meteorological observations with information extracted from remote sensing data
to calculate evapotranspiration and other energy exchanges at earth's surface. The
result shows that SEBALET varies between 3.3 mmday and 4.9 mmday in the
study area. The estimated ET was compared with the vegetation indices and
surface temperature to see their variations among the classified land cover classes.
Terraced agriculture has the highest ET(4.9 mmday ) partly due to its crop growth
stage as compared to other land cover classes. Spatio-temporal distribution of
actual ET can assist us to better understand evapotranspiration pattern of different
land use systems and would help to establish links between land use, water
allocation, and water use planning.
