Rice husk is a by-product of the rice milling industry. It is also abundantly available. Rice husk is a residue produced in significant quantity on a global basis. While they are used as a fuel in some regions, in other countries they are treated as waste, causing pollution and disposal problems. Due to growing environmental […]
Arsenic content of groundwater got reduced through storage in ponds
An inventory survey (1998-2000) was conducted on land and water use pattern in Gotera mauza under new alluvial zone of the Gangetic delta in West Bengal. The survey revealed that ponds were continuously filled with arsenic contaminated groundwater through peoples’ practice of filling the ponds with Tubewell water in non-rainy periods mainly during pre-monsoon (April […]
In quest of a pattern in annual rainfalls
Heat from the sun vis-à-vis evaporation and rainfall: Cause and effect Sun is the source of all energies. Heat from the sun is the driving force in the earth’s hydrological cycle. It is due to the attraction of the sun that earth and the other planets move in their respective orbits. The amount of heat […]
Mauza wise water conservation
Mauza wise or village wise water conservation is hydrologically proved to be the most beneficial method for conserving rainwater as excess surface run-off from an area or watershed. https://water-soil.org/hydrological-balance-planning-irrigation-coastal-areas This method of rainwater conservation is very much useful where annual rainfall is sufficient enough to fill the dugouts. Natural low depression points are generally selected […]
Fringe areas greatly influence the development of the Sunderbans
Either of the expansion of conventional agriculture in the community development block or the development of the forest by itself can not exclusively address the problems of Sunderbans Biosphere Reserve (SBR). Only the development of fringe areas can claim to have a solution for the development of SBR. This is because the total character of […]
Agroclimatic analysis for onset of agricultural drought period in a coastal area
Studies on air temperature are necessary for assessing climatic conditions favourable for growing crops and also for altering the cropping pattern, if necessary, on the basis of hydrological balance in a particular area. Contai (21 ̊47´.15 N Lat ) coastal area by the northern shore of the Bay of Bengal is a well […]
Water harvesting in coastal and deltaic region
Water harvesting in coastal and deltaic regions is the basic and problematic task for any other developmental works in these areas. The problem further intensifies with the ingress of sea water in rivers, channels and groundwater. Water harvesting in suitably designed ponds, mixed farming with agroforestry and fish farming may rule out the complexities to […]
Quality of Groundwater in Coastal Areas depends on distance from Surface waterbodies
Quality of water is the major problem In the coastal areas. Electrical conductivity is one of the major parameters to determine the quality of water. Though the saline water ingress in the aquifer is the common fact in the coastal areas, distance of surface water bodies like rivers, channels and sea has great influence […]
Hydrological balance approach for planning irrigation in coastal areas
An irrigation plan is presented using hydrological balance for heavy clayey soils in coastal areas of Contai, District -Midnapore, West Bengal, India. Though many workers have shown the importance of farm ponds, especially in third-world countries, village-level planning should be given stress due to the fragmentation of land holdings in the study area. In […]
