Water Balance of Petrolina, Pernambuco—Brazil Antônio Heriberto de Castro Teixeira, Bernardo Barbosa da Silva
Abstract In order to use the natural resources of a region, it is necessary to know the thermal and water conditions and their interaction. One way to find out about it is by realizing the climatic water balance. This balance is based on the calculation of pluvial precipitation and potential evapo-transpiration. The objective of this paper was to realize the serial water balance in the region of Petrolina-PE. Daily data of precipitation and air temperature from Embrapa Semi-arido's agro-meteorological station was used. The periods of water shortage and excess were defined and trends for the coming years were taken into consideration. |
