According to current scientific understanding, the state of well being and survival of the people in Bangladesh will be under serious threat from climate change over the coming decades. This paper hence proposes a way to integrate the youth actively to entire environment movement process. Excess accumulation of these salts may turn the soil alkaline. The infrastructure network was economically updated using the satellite data. The various after effects are the following: 1.
There is a high tide warning of 4. Help us delete comments that do not follow these guidelines by marking them offensive. The best way of keeping watch over the problem of waterlogging is by observing variations in the groundwater level. Datasets on the depth to the groundwater table, rainfall, water depth, soils, and geomorphology slope were also collected and digitized in ArcInfo. Due to this shortening of crop period the crop yield is reduced considerably. Seepage of water from earthen canals also adds significant quantity of water to the underground reservoir continuously.
It is required to ensure sustainable measures to face the climate related challenges. You have to make sure that when you make your letter the details are intact,concrete,connected and valid. The hydraulic conductivity of the B horizon can change by as much as two orders of magnitude over a 10 m lateral distance. Chennai, Hyderabad, Ahmedabad, Srinagar, Guwahati, Jaipur and even Dehradun and Lucknow have the same issues during monsoon. I will do my best to perform this in my best ability and to be respectful to your people. The need of the hour is investing in better, effective drainage system across all major cities. Therefore its early detection is possible by keeping a close watch over the yields and also on the variations in the groundwater level.
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. Lack of cleanliness is resulting in the increase of mosquitoes and thereby diseases like dengue and malaria also increasing. Wheeler Publishing House, New Delhi, India, 2000. Good drainage facility is very essential. Satellite data was interpreted for the identification of water bodies, land use, land cover classes, and waterlogged areas. This study, covering 677 km2, demonstrates the benefits of using ArcInfo to automate, manipulate, analyze, and display geographic data for the district.
Landslides occur as soon as. The total acreage being irrigated has increased rapidly. It is observed that there is a lack of planned and adequate drainage network system in the Chalna Pourashava. In Bengaluru the situation is pathetic. 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. Moreover the human acts on the natural environment making the condition more severe. In worst cases the water-table rises so high and close to the ground surface that the fields turn into swamps and marshes.
Taken remedial actions in this regard included the use of sandbags, debris and wood logs, rubbles and stones, construction of contours and drainages. Sometimes even if water table is below the root-zone depth the capillary water zone may extend in the root-zone depth and makes the air circulation impossible by filling the pores in the soil. The relative importance of soil, landform, climatic and drainage factors on waterlogging intensity was assessed from 1984 to 1986. India meteorological Department, Mumbai forecasts heavy rains at isolated places in the next 24 hours. It may also be affected by keeping intensity of irrigation low. Thus water logging in the urban area is not a new problem.
The urban area has been experiencing water logging for the last few years even a little rain causes a serious problem for certain areas. Other parameters for identifying areas prone to waterlogging included type of land use, soil geomorphology, groundwater depth, and rainfall in addition to canal proximity. Waterlogging is caused by the development of a perched watertable on the subsoil clay. But in principle both measures aim at reducing the inflow and augmenting the outflow from the underground reservoir. This will cause the water catchment area was destroyed and lead.
The water from rivers may infiltrate into the soil. The steps taken to reclaim such areas include implementation of drainage schemes, provision of deep drains, excavation of new channels and improvement of existing ones, construction of sluices with marginal embankment and installation of tube wells. Thane was a close second after Bhiwandi, with a rainfall of 204 mm. The waterlogged areas were analyzed to find their relationship to hydrological and terrain characteristics. This is partly due to a lack of data and lack of resources to process the data.
We need to build good quality wide roads with no potholes to decongest the cities when the skies open up. In low temperature the bacteriological activities are retarded which affects the crop growth badly. Since Mumbai receives more rain than many other major cities in India, the commercial capital of the country suffers the most and makes it to headlines. The problem of waterlogging develops in its full form slowly. Most canals in this area are unlined and cause severe seepage problems.
