Dendritic drainage In geomorphology , drainage systems , also known as river systems , are the patterns formed by the streams , rivers , and lakes in a particular drainage basin . They are governed by the topography of the land, whether a particular region is dominated by hard or soft rocks, and the gradient of the land.
Loss of the mucous plug means that labor will most likely start within the next 2 to 3 weeks, sometimes sooner, but that is the norm. If you are less then 36 to 37 weeks you need to inform your Dr. or Midwife if you lose your plug, as this could be a sign of an early delivery.
Important Notes to Remember. It is important to remember that while losing the mucus plug is an indication of labour, it does not mean that labour is about to begin right away. For women giving birth for the first time, the mucus plug is usually expelled days before labour begins and may often be a sign of early labour.
