TYPES OF RIVER DRAINAGE PATTERNS
Dendritic drainage pattern dendritic drainage pattern require the following condition to be formed: rock should be uniformly resistant to erosion this pattern is not dependent on geology characteristics of dendritic drainage pattern the pattern is tree shaped the tributaries join the main stream at acute angles example of rivers with dendritic pattern include tigela, mooi and umgeni in the south Africa Radial drainage pattern radial drainage pattern is formed on dome shaped hill, conical hill, mesa or butte characteristic of radial drainage pattern streams radiate outwards from the central high point. example of areas with radial drainage pattern includekoffiebus and teebus in south africa Trellis drainage pattern requirement for trellis drainage pattern to be formed parallell ranges of fold mountains or alternate layers of hard and soft rock a strong main stream the pattern is dependent on the relief and the geology of the area characteristics of the trellised drainage pattern t...
