Balanço hídrico espacial da região de Ilha Solteira Itapura e Pereira Barreto

The water balance is necessary for irrigation management, and it is based on the fact that this region has a good availability of water due to the presence of many masses of water of different volumes; This way, the climatic water balance generates data of excess and deficit of water. It is possible to better explain this point through the Thornwaite and Mather method; Subsequently, to obtain data referring to water demand and to interpolate the results, and expose it with the help of maps to visualize geographically the region of Itapura, Ilha Solteira and Pereira Barreto. Next, to identify the level of deficit in the whole region comprising the municipalities of Ilha Solteira, Itapura and Pereira Barreto, it was the objective of this work. The use of remote sensing by use of maps determine the movement to where the deficit of water goes along the year 2015, and the period from 2012 to 2015, with a spatial water balance. Thus, it is possible to analyze the accentuated water deficit in the months of January, August and October of 2015, with interpolation maps, as well as, this characterization in the interpolation maps of the mean period of water deficit of the years 2012 to 2015. Therefore, it is recommended to use the Method of data processing, and expose the results on interpolation maps to better visualize variations in water demand, facilitating decision-making on water management.
