ABSTRACT

A research was conducted at Tono irrigation system in the Upper East Region of Ghana to evaluate the irrigation performance of the system based on some selected indicators with the help of GIS and Remote Sensing Techniques. The indicators, namely Overall Consumed Ratio (OCR), Relative Water Supply (RWS), Relative Evapotranspiration (RET), Depleted Fraction (DF) and Crop Water Deficit (CWD) were used at 3 command areas, Bonia, Korania and Chuchuliga. Potential evapotranspiration and actual evapotranspiration were estimated with Penman Monteith method and Surface Energy Balance System (SEBS) using Aster Satellite image, respectively. The seasonal average values of the irrigation performance indicators showed that water delivery system at Tono irrigation project based on the selected command areas is poor. Assessment of the irrigation performance of the other command areas is highly recommended.

Key words: Irrigation Performance, Remote Sensing, Aster Image, Evapotranspiration.
