positive effects of floods

Floods can cause damage to homes and possessions as well as disruption to communications. Some suggestions are worth mentioning to achieve sustainability in the park ecosystem (Direc­torate, Kaziranga National Park, 2002). Floods contribute to the health of ecologically important wetland areas. After that there is a steep fall in percentage increase of almost all the animals. Our team of exam survivors will get you started and keep you going. Flooding in the basin comes as a godsend for all the creatures that depend on the wetlands for their very survival. What is the reserve food material in red algae? This again results in the overall reduction of the area under water bodies. Tall grasses should be burnt for this purpose. km (8.5% of the total area) of area, which decreased to 27.4 sq. Annual flood replenishes the dry water bodies and streams with high amount of water and makes it again suitable for these animals. The floodwater also helps in washing away the water hyacinth from beels, streams and nallahs, which grow into a very thick, impenetrable cover. Moreover, the stated relation between flood and quantity of biodiversity can be emphasized with the comparison of the percentage increase/decrease in some selected animal population (Figure 1) and flood level taken in different areas of the park in different years (Figure 2). Floods contribute to the health of ecologically important wetland areas. Percentage increase of these animals taking 1966 as the base year shows a stable growth up to 1984 except elephant and samber. There is a correlation between the magnitude of flood and the quantity of biodiversity of the area. The populations of many ancient civilisations concentrated along the floodplains of rivers such as the Nile, the Tigris and the Yellow because periodic flooding resulted in fertile, productive farmland. But with increasing flood of the river Brahmaputra siltation occurs, which results into fragmentation of beels. The river will be carrying huge amounts of pollution and silt that will destroy floors, walls and any electrical gear. Flood has its both short-term as well as long-term negative impact on its biodiversity and both results into severe … tend to be affected more than more economically developed countries. Welcome to BiologyDiscussion! Remote sensing could serve as an effective tool to accomplish this job timely and cost effectively (Singh and Kumar, 2004). Effects of Floods: i. Content Guidelines 2. Flood is responsible for creating different site conditions and soil formations, preferred by different types of vegetation. Doug Donald has been writing online since 2004, covering business, relationships, health/exercise and food. The worst and the most pathetic situation is that some animals especially the calves and the aged ones and the deer species are sometime washed away by the current of the flood of turbulent river Brahmaputra. They also carry and deposit nutrient-rich sediments that support both plant and animal life in wetlands. Explain the factors which cause dormancy. Share Your PDF File Positive Impacts of Flood on Biodiversity: This national park developed naturally with its numerous biodiversity. Floods inundate wetlands with fresh waste. More people drown in their cars in the floods than anywhere else, The floods and the storms also can knock down the power lines and the electrical currents can travel through the water. Floods contribute to the health of ecologically important wetland areas. Thus there will be an increase in Fishing after floods as the nutrients serve as food for fishes Floods if properly planned and managed (by containing They also carry and deposit nutrient-rich sediments that support both plant and animal life in wetlands. Again, a number of floral species have disappeared in the river water with the eroded land (SAC, 1999). What are the different sources of air pollution? Even, sometimes undergrowth of the forested areas also gets submerged under water during high floods. What are the general characters of bryophytes? They also carry and deposit nutrient-rich sediments that support both plant and animal life in wetlands. LEDCs often do not have the resources to prevent flooding or deal with the aftermath of flooding. Flood also maintains the water quality through cycling. The animal mortality during the flood went up to 629, where numbers of rhinos being 39 and the worst affected hog deer being 506 (Tables 5, 6, 7). 3. Floods inundate wetlands with fresh waste. Effort should be made to increase the area under beels and short grasses wherever possible. Soil deposited by floodwaters prevents erosion and helps maintain the elevation of land masses above sea level. Negative Impacts of Flood on Biodiversity: In recent years, flood has become a common feature in the park with its increasing magnitude. The contaminated water will spread quickly over an area – causing public health issues and killing fish. Many population centres depend upon groundwater and underground aquifers for fresh water. Flooding also adds nutrients to lakes and streams that help support healthy fisheries. The grazing animals in the Kaziranga National Park severely suffer from shortage of fodder during flood situation. Flood also maintains the water quality through cycling. Name the types of nitrogenous bases present in the RNA. Answer Now and help others. The rapidly receding land of the Mississippi River delta is a direct result of man-made flood controls and levees that prevent topsoil-replenishing sediments from being deposited in the delta. For these, elevated platforms of the size of about one hectare or more have to be created, planted and maintained. The cover of water hyacinth helps water bodies becoming shallow and harms the existing wetland ecosystem. People have come to regard floods as disasters.
