In this paper, a new hydromatrix power generation unit is presented. This presented hydromatrix power unit is aimed to convert the water movement in the main river branches into electrical power. It is found that the generated power based on the proposed hydromatrix power can be reached 5 GW/h in Egypt. the proposed hydromatrix power unit based on the under shot water wheel type and the generated electrical power using this proposed unit is calculated at different mode of operation is presented
