Description:

This paper presents the methodology and results of a research project that integrates technological tools for developing a complete system for monitoring and determining irrigation demand on a systematic basis in Cyprus such as multispectral satellite remote images, GIS, evapotranspiration models and micro-sensor technology. The main aim is to estimate evapotranspiration in Cyprus and furthermore to undertake the required measures for an effective irrigation water management for the whole Island. Evapotranspiration (ET) is difficult to be determined since it combines various meteorological and field parameters while in literature quite many different models for estimating ET are found. A wireless sensor network will act as a monitoring tool for providing measurements of the necessary required parameters such as meteorological, climatic data and other auxiliary parameters required to be used in the irrigation models for determining the irrigation demand. Reflectance will be determined directly from the satellite images. GIS will be used to create a database for all the collected data. Available methods found in the literature for determining irrigation demand using satellite remotely sensed and other auxiliary data are presented. Afterwards, the methodology is briefly described, and some results of the FAO Penman-Monteith
method by combining satellite images (ASTER and Landsat 7 ETM+) and meteorological station data are shown.
