There are a limited number of studies addressing the spatiotemporal variability of premonsoon flash floods and their driving forces in Bangladesh. This study examines longterm trends in temperature, rainfall, and the frequency and magnitude of flash floods in the five most vulnerable haor districts of northeastern Bangladesh. Temperature, rainfall,...

This study was carried out to analyze the pattern of the changes in temperature, rainfall, and the frequency and intensity of flash floods in the Haor districts of north-eastern Bangladesh over decadal scale periods. Regression models predicted a slow but gradual rise of maximum temperature to the extent of about 1.06-1.94% per decade which might p...

The study examines the long-term and seasonal climatic variations in north-western part of Bangladesh (NWPB). Long-term variation of different climatic parameters reveals that significant increases in temperature are associated with decreasing evaporation which could be attributed to wind speed variation and seasonal variation of temperature. Incre...

The study area is situated in Old Dhaka, covering an area of 13.5km2 (5.2mi2) and lies towards the northern bank of the Buriganga river. Thirty six dug well water samples from different houses along three transects and four Buriganga river water samples from four different Ghats (boat terminals) were collected for water quality assessment during bo...

Water scarcity and water pollution both have been the greatest hazards in Bangladesh among other SE Asian countries. Dhaka is the capital and central city of Bangladesh, one of the most densely populated cities in the world. The population of Dhaka city is about 14 million and the density is 45, 000 square km. Dhaka city is dependant mainly on grou...

Water scarcity and water pollution have been the greatest hazards in some developing countries like Bangladesh among other SE Asian countries. Dhaka is the capital and central city of Bangladesh, one of the most densely populated cities in the world. The population of Dhaka city is 14,399,000 and the density is 45,000 km2 (115,200 mi2) (Bangladesh...

Dug wells are installed at shallow depths and are largely located in sands, gravels and other interspaces through which precipitation infiltrates and percolates into the underground aquifers due to gravity. Dug wells were mentioned as early as in 1968 as a source of drinking water for Dhaka dwellers (Khan and Stockard, 1968). The study area is situ...

Attempts have been made in this paper to overview the present agricultural inputs for crop production and crop economy in the lower Gangetic plain. Results of the field survey show that the average labour requirement of Boro rice production is 35 person-days/acre. The fertilizer application by the farmers is not balanced and is well below the recom...

The Ganges River water and riverbank shallow groundwater were studied during a single wet season using the hydrochemical and isotopic composition of its dissolved load. The dissolved concentrations of major ions (Cl−, SO42−, NO3−, HCO3−, Ca2+, Na+, Mg2+, and K+), trace elements (barium (Ba) and strontium (Sr)) and stable isotopes (O and D) were det...

Water quality and hydrochemistry of Shariatpur district were evaluated in terms of hydrochemical composition and some important physico-chemical parameters. The groundwater of the study area is good for drinking, domestic as well as for irrigation purposes. Among the major ions, shallow tube well waters give higher concentration of Ca2+ which range...

 This paper deals with an environmental impact assessment of low water flow in the river Ganges during a dry period at the Khulna and Mongla port areas in south-western Bangladesh. Large-scale surface water withdrawal in India after commissioning the Farakka Barrage causes a drastic fall in the Ganges low-flow condition within the Bangladesh territ...
