No, we do not think that the shape course will change as the shape course has been the same for over a decade. There is not much improvements as both pictures above are filled with buildings along the Singapore river. If nothing is being done to it, it will stay the same as even if they want to expand, they cannot as there are many other buildings surrounding the river. However, if Singapore governments wants to reclaim part of the river landspace for future uses, the river will get smaller. The river eventually will reach the Marina Barrage. It will only change under circumstances such as natural disasters eg earthquake. Therefore, the river will also be a boat tour for tourists.
