Use of automated weather stations and mathematical models to determine evapotranspiration

open access: yesTecnología y ciencias del agua, 2013
La evapotranspiración es una variable esencial en el manejo del agua y planificación del riego. De ahí la importancia de su cuantificación y del análisis de cuáles métodos la estiman de manera satisfactoria en el ámbito local y de cuenca. En tal contexto,

Potential Evapotranspiration Methods and their Impact on the Assessment of River Basin Runoff Under Climate Change [PDF]

open access: yes, 1994
The current trend in increased amounts of green house gases in the atmosphere will likely affect both precipitation and evapotranspiration, which will in turn affect the runoff response of river basins.

Impact of Semi-arid Weather Conditions on Wheat and Maize Yield [PDF]

open access: yes, 1994
In recent years the need for assessing land capability and planning production has grown. In this paper we try to describe the impact of the weather on crop yield in semi-arid regions where weather variability and uneven distributions of precipitation ...
