الملخص EN

Water budget is one of the most important components of hydrological cycle within earth atmosphere system.

It can be applied to any part of Earth's surface.

Water budget technique can provide us with useful information about actual evapotranspiration, water surplus, deficit and changes in soil water storage or availability of soil moisture.

This budget gives knowledge of the volume of input and output of water.

In this paper a simple water budget is applied to the land area of WestJJank-Palestine.

It makes use of monthly and yearly values of meteorological data, as well as variables like precipitation, temperature, evapotranspiration and heat index, along with values of latitude and daylight.

The paper also presents results of the twenty-two years period, 1975-1997.

It seems that these results conform to the known climate features of the period in this area.
