It is a river drainage pattern...as a river flows along a valley, small tributaries feed into it from the steep slopes of the valley sides and they enter the main river at about an angle of 90 degrees, causing a trellis like appearance of the drainage system. The Trellis system is the alternative to the Dendritic System, which means that tributaries flow into the main river following a pattern like branches of trees
