Bangladesh is an area with high density which means there is more water flowing in the area which means that it is more likely to flood. Urbanisation and concrete: Much of the river Ganges has been diverted for irrigation‚ which increases the deposition of silt and reduces the channels capacity. This affects the river system‚ meaning there would be a high chance of flooding. Diverting flow for irrigation however‚ is only one effect on the river‚ the other is damming. This is an advantage- as the

such as bridges‚ and erosion of stone statues. Acid rain describes any form of precipitation with high levels of nitric and sulfuric acids. It can also occur in the form of snow‚ fog‚ and tiny bits of dry material that settle to Earth. Acid rain is rain consisting of water droplets that are unusually acidic because of atmospheric pollution - most notably the excessive amounts of sulfur and nitrogen released by cars and industrial processes. Acid rain is also called acid deposition because this term

1998). Initial sediment supply probably came from the Iapetus Ocean. Thermal subsidence increased accommodation in the basin and periodic rise and fall in sea level and changes in sediment supply‚ from marine to terrigenous‚ probably resulted in the deposition of alternate carbonate and clastic sequence (Henriksen & Higgins‚ 1998). These sediments were probably deposited in a predominantly shallow marine environment in the shelf‚ medium water environment at the slope and deep marine environment in the

the Colorado River (or the Colorado River’s ancestral equivalent) changed a long time ago when the river’s base level got opened by the Gulf of California. This increased the rate of erosion and nearly cut all of the Grand Canyon’s current depth. The terraced walls of the Grand Canyon were created by differential erosion. A long time ago volcanic activity deposited ash and lava over the area which completely obstructed the river. These volcanic rocks are the youngest in the Grand Canyon. The Canyon’s

conservation techniques‚ and over exploitation of land for crop production due to population stress‚ leads to enormous soil erosion. It will take hundreds of years to form an inch of soil‚ but in no time it gets washed away down the slope due to erosion. SOIL CONSERVATION Soil Conservation is the process by which the loss of soil is checked‚ reducing the velocity of run-off through erosion control measures for maximum sustained crop production and for protection of human lift. So conservation of soil
