Formulate the Hypothesis
Settlement development together with heavy rainfall impact negatively on mass movement in the Bluff in Durban
Answers
Answer:
To understand this Hypothesis, it is important that we need to get familiar with the dynamics of heavy rainfall and settlement development on mass movement.
Explanation:
In regions that receive heavy to very heavy rainfall or precipitation, it is obvious that we get to notice substantial big mass movements. Some may also be noticed in the form of small or big land slides in certain regions.
It is thus important for us to get more familiar with these mass transport process that are triggered by heavy rainfall.
It is certain that three main factors that could result for such mass movements can be related as tectonics, geomorphology and geology factors. Apart from this, the process of mass movement could also be seen more prevalent in areas that have steep slopes and less or no of forest covers.
It is important that the region that has steep slopes, should in fact have a crown cover of forest and trees that can in fact prevent the initiation of the motion.
Apart from this, in most cases it is also observed that the majority of mass movements also get triggered on account of perched water table that may flow within the thin surface under the top soil. The water is able to in-filter inside the top soil layer due to heavy rains.
In some cases, where the mass movement is prevalent it is noticed that the distance between the toe t the land slide may be as much as 50 to 60 meters. It is also noticed that the landslide is more prevalent in the middle and bottom regions of the flowing mass, while the top layer helps in offering with blockage to the land slide.
The mass movement can also be noticed in few regions in Durban in case of heavy rainfall that may be going on for two or three days.
Answer:
Regions that receive heavy to very heavy rainfall or precipitation, you can find substantial big mass movements. Sometimes big or small landslides in certain regions also happen. Three main factors contribute to such mass movements which are, geology, tectonics, and geomorphology factors. In some cases, where the mass movement is prevalent it is noticed that the distance between the toe t the land slide may be as much as 50 to 60 meters. It is also noticed that the landslide is more prevalent in the middle and bottom regions of the flowing mass, while the top layer helps in offering with blockage to the land slide.
The mass movement can also be noticed in few regions in Durban in case of heavy rainfall that may be going on for two or three days.
