The developed technology can easily be transferred and applied to catchment areas experiencing similar problems. Moreover, those drains are insufficient to cover the full drainage resulting from rainfall runoff. Improved management of storm water is critical, if addressed inadequately, it will jeopardize progress of poverty reduction targets and sustainable development in all economic, social and environmental dimensions. Mumbai witnessed heavy rains in the last 24 hours. It not only increases the siltation on the floodplains and river beds but also creates a risky situation for the inhabitants inside the boundary of embankments. Bangladesh is one of the most vulnerable countries to climate change due to global warming. When the storage starts building up in the initial stages the crop growth is actually increased because more water is made available for the crop growth.
Municipal administrations need to be professionalised and expert supervision needs to be brought in over the development plans hatched by civic bodies. Most canals in this area are unlined and cause severe seepage problems. The study ended with drawings a set of recommendation based on the findings to mitigate the waterlogging problems in that city. Garg, Coordinator Centre for Remote Sensing Department of Civil Engineering University of Roorkee Roorkee-247 667 India Tel. The need of the hour is investing in better, effective drainage system across all major cities. There is a high tide warning of 4.
Bangladesh is facing the threat of global warming and sea level rise. Let's work together to keep the conversation civil. It helps the crop growth. Waterlogging intensity is low where topsoils are deeper than about 0. Also when harmful salts start appearing on the fields as white incrustation or deposit it indicates that waterlogging is likely to follow.
It creates an unhealthy environmental situation and causes inconvenience to the residents of the Pourashava including damages to the infrastructure, loss of business and spreading of diseases. The real estate sharks have encroached upon once famous water bodies — lakes and ponds. To create such conditions it is not always necessary that under groundwater table should enter the crop root-zone. Saline soils include 10 lakh ha in arid and semi-arid regions of Rajasthan and Gujarat and 14 lakh ha in black cotton soils. This becomes essential in order to ensure safe inhabitation and enhanced socioeconomic engagements of the residents. The total acreage being irrigated has increased rapidly. The reason is that the soil contains excessive moisture content and it does not give proper tilth.
By lining the canal section: When the canal section is made fairly watertight by providing lining the seepage loss is reduced to quite a good extent. From Name Address To Name Address Dear Sir, This is to inform that your project is accepted by our company and we are very happy about that. In low temperature the bacteriological activities are retarded which affects the crop growth badly. Implementation of drainage schemes: The waterlogged area may be reclaimed by introducing overland and underground drainage schemes. The data has been analyzed by using factor analysis. When the rain lashed national capital Delhi and its suburbs last Friday and Saturday, many parts of the metropolis underwent water and the public suffered. Due to the phenomenon urban deterioration through different natural disasters can be seen.
Construction of earthen embankments for flood control, irrigation and drainage have been the history of Bangladesh but these can't solve the flood problem, effectively and permanently because of their ease of vulnerability with rain splash and flow of flood water. On the basis of overall present situation in Bangladesh, the paper also suggests a proper design and construction method of embankments to control and minimize the extent of flood hazards in the long run and also concluded that to achieve consistent standards of management of flood embankments, and also to raise these standards to optimize their performance, require a better understanding and application of good practice, and b a range of research actions. It is required to ensure sustainable measures to face the climate related challenges. The study has also found that the inhabitants of Dhaka city faced different problems due to waterlogging, most influential problems are; productivity loss, increase of construction and maintenance cost, environmental problem, sanitary problem, damage of roads, financial loss, health hazard, increase mosquito, disruption of normal life and economic loss etc. A buffer map of the canal network was generated in ArcInfo.
Help us delete comments that do not follow these guidelines by marking them offensive. Surface water resources are replenished by floodplain inundation and groundwater recharge from landscapes, but these events are episodic so the dynamics of the water balance need to be understood to fully appreciate the implications of variable and changing climate. These factors are proximity to a canal; groundwater, soils, rainfall, land use, and land cover; and geomorphology. Solution to the Problem of Waterlogging: The problem of waterlogging may be attacked on two fronts. Other methods are of local importance and hence benefit derived from them is limited. Regional Space Applications Programme, Bangkok, Thailand, 1996. Waterlogged Area Analysis with ArcInfo Editor's note: Excessive irrigation in areas with poor drainage causes waterlogging and salinization of the soil.
Continuous high water levels indicate that the groundwater storage is building up which may create waterlogging in the area. Air spaces in the soil are filled with water, and plant roots suffocate. The infrastructure network was economically updated using the satellite data. According to a report in 'Times of India' a redundant drainage master plan prepared way back in 1976, the Delhi government like every year before the monsoons has yet again set out to revive its promise to clear the mess by putting in place a new master plan. The States mainly affected and the extent of area rendered infertile and unproductive are given in Table 11. Proper water resources management is must in this problematic area.
