1a. Two reasons that the mass of the bag levels off with time include (1) equilibrium and (2) hydrostatic pressure. Equilibrium refers to the concentrations becoming equal. If there is no longer a higher concentration and lower concentration between the water and sucrose‚ osmosis can no longer take place. Osmosis can only occur when water is traveling from a higher concentrated area to a lower concentrated area. Hydrostatic pressure occurs when the bag reaches maximum capacity. Water will enter the

of sediment a river can transport. At low velocity only fine particles may be transported (clays‚ silt and fine sands). Large-calibre material can be moved when velocity increases. Because the maximum particle mass that can be moved increases with the sixth power of velocity‚ when discharge levels are high‚ for example during a flood‚ much larger boulders can be moved. The Hjulström curve illustrates the relationship between velocity and competence. It shows the velocities at which sediment will

This paper will discuss the economic role of freight transportation in Singapore’s economy and how Singapore’s advancement into the global economy affects the demand for freight transportation locally. 2.

connection between sediment aggradation‚ erosion and climate in a desert environment of the Majes valley‚ southern Peru. Luminescence dating of terraces and fans shows that sediment aggradation correlates with wet time intervals on the Altiplano‚ suggesting a climatic influence on the aggradation–degradation cycles. Major periods of aggradation occurred between *110–100‚ *60–50 and 12–8 ka. More precipitation in the Majes catchment resulted in increased erosion and transportation of sediment from the hillslopes

work within rivers. It is through this knowledge that we will better undertand the processes at work in the geomorphology of the drainage basin. The role of rivers can be understood in very simple terms. The river’s role is to balance its load and transport it to the ocean. But this this idea of rivers as merely transporting weathered material to the ocean is too simplistic. In reality the river changes in energy‚ discharge‚ velocity‚ channel charactersitics and load as it extends down its course. These

Long shore drift is a process where sediment is moved along a beach by the action of waves.When the waves approach a beach‚ the base of the waves drags along the sea bed picking up sediment and causing the wave to break‚ the wave then swashes up onto the beach face carrying sediment with it. Gradually the build up of sediment pushes the sediment up the beach which it is then able to dry out to become light enough to be deposited further up the beach. The sediment found at south muriwai beach is made

Alluvial fan sediments are dominated by gravely deposits‚ which typically show down-fan decease in grain size and bed thickness and an increase in sediment sorting. Overall‚ alluvial fan deposits tend to be characterized by strongly developed thickening and coarsening upward successions‚ caused by active fan progradation or outbuilding. 1.1 Debris flow dominated fans facies Debris flow dominated fans facies are characterized by lobes of poorly sorted‚ coarse sediment‚ commonly with
