Fan and fern shaped catchment
WebQualitatively, shapes are described as rectangular, square, fern, fan, parallel etc. ForFan shapedcatchments thepeak occurs early because of shorter tc, giving rise to narrow hydrographs with high peaks. ForFern shaped ones,peak occurs late because of longer tcgiving rise to broad bases and lower peaks. WebThe fan shape watershed tends to produce higher peak rate of runoff very early than the fern shape, due to the fact that in former one all parts of the watershed contribute the runoff to the outlet simultaneously, comparatively in little period of time than the fern shape watershed. 3.
