Essay On Land Subsidence In Jakarta

Flash floods may cause loss of lives and properties. Soil erosion will leads to loss of minerals for the land. The land cannot be used for

The extensive glaciations of the region has resulted in poorly developed top soil and soil horizons .Soils generally have low shrink swell potential because of their minimal clay content but high erosive potential because generally they are thin and

The Earth is filling in the space where the water once was, causing a reaction known as subsidence, making the ground sink to over a foot in some areas of the central valley. Specifically, around Sack Dam, an important water containment resource, is sinking deeper than all the surrounding area, caused by all the drilling. “Water traditionally flowed with gravity.” Cannon Michael, president of the Bowles Farming Company (Richtel, page 5) stated. “It isn’t going to run uphill.”

2.8 Main Cause of Flood According to Jabatan Penerangan Malaysia (2012), issues of flood that happen certainly had their own causes. There are many causes such as: 2.8.1 Continuous Rain Continuous rain without stopping can cause flooding. In low areas, rain water will flow into the river. River filled with water will overflow causing lowland area are flooded.

4. Habitat alteration: Removal and reduction of natural habitat by flooding, soil erosion and water

In a way that it affects our environment is a change in mass that gets caused and by our surface getting distributed our earth gets pushed down further and further

As shown in the documentary, Rivers and Tides, change does not always have a negative outcome. In the documentary the artist builds sculptures in many different environments and they’re always made out of things only found in nature. After he builds the sculptures the surrounding environment begins to change. When he built a cone like structure at the edge of the shore, the tide came in and the structure could not be seen. When he built a structure in the forest, it became engulfed by the growing vegetation around it.

The formation of the main reason is due to flood alluvial. When floods occur, especially in mountainous areas, the following

These developments were created to keep up with the large urbanisation rate the area was receiving. Most of the creeks and waterways were built over for development reasons. There was a destruction of the mangroves, saltmarsh and

The erosion process can increase or decrease in volume. Erosion is dependent on specific geological agents.

In the 1970s when the last complete surveys of land subsidence were made, subsidence in surplus of one foot which had affected more than 5,200 square miles of irrigable land (one half the entire San Joaquin Valley). Land subsidence has continued and has slowed down since the 1970s because of reduction of ground water levels able to be done so by supplemental use of surface water for irrigation.

(source two). This happened because she used too much groundwater and didn’t have any water left over. Accordingly, if we keep using too much water, there will be changes in land mass. “Scientists are already sounding alarm bells about pumping too much groundwater.”

It occurs due to rise in global warming which occurs due to increase in temperature of atmosphere by burning of fossils fuels and release of harmful gases by industries. Climate change has various harmful effects but not limited to melting of polar ice, changes in seasons, occurrence of new diseases, frequent occurrence of floods and change in overall weather scenario. • Loss of Biodiversity: Human activity is leading to the extinction of species and habitants and loss of bio-diversity. Eco systems, which took millions of years to perfect, are in danger when any species population is decimating. Balance of natural processes like pollution is crucial to the survival population is decimating.

INTRODUCTION URBAN LAND USED SYSTEM Urban land use system means the system which manages the land area in urban cities. The land in urban areas should plan very well to mitigate the issues that arise in the future. Planning of buildings, roads, highways, rail ways, ports, stations and flyovers has to be planned under this system. It is very important to plan the urban land properly by placing the infrastructures in the proper places because wrong management plans will creates huge cost for the economy.

The most recent flood occur in Kuching, Sarawak where heavy rainfall caused some areas around Kuching to be inundated by flood waters and most roads became congested as they were impassable to traffic. The heavy downpour was still continuing around Kuching and several stalled vehicles were left on the flooded roads. Several key places were flooded including the Sarawak General Hospital, Sarawak Contingent Police Headquarters at Jalan Badaruddin, Padungan fire and rescue station, Faculty of Medicine at Universiti Malaysia Sarawak, Universiti Teknologi Mara Samarahan campus, and areas around Padang Merdeka. Meanwhile, a landslide was reported to occur at mile 18 Jalan Serian Tebedu which made the road impassable. Several villagers who lived around the river banks especially in
