Environmental flow ensures ecological health status of a river. The Gorai River is the major distributary of the Ganges River in the right bank and the main source of upland freshwater inflows to the southwestern region of Bangladesh. The aim of the research is to estimate environmental flow of Gorai River and to assess flow characteristics of the...
Article
Full-text available
The main source of irrigation water in Bangladesh is groundwater, hence its quality needs to be ensured; otherwise, it can damage soil and reduce crop production. In current research, work by analyzing hydrogeochemical characteristics of groundwater different water types have been assessed to find out the suitable irrigation water of Godagari upazi...
Article
Barind region of Bangladesh is severely affected by agricultural drought. A geo-statistical approach had been conducted to summarize spatial and temporal variation of agricultural drought in Barind region. Markov chain model has been used to evaluate probabilities of getting a sequence of wet-dry weeks over this region from the rainfall data record...

Full-text available
In the semiarid Barind region, episodes of agricultural droughts of varying severity have occurred. The occurrence of these agricultural droughts is associated with rainfall variability and can be reflected by soil moisture deficit that significantly affects crop performance and yield. In the present study, an analysis of long-term (1971–2010) rain...
Article
Full-text available
Environmental flow is necessary for securing ecological health status of a river. Around the Dhaka city of Bangladesh the Turag, an ecologically critical area, is an important river. Environmental flow assessment of the Turag can help to sustain ecosystem and navigation in it. The aims of the research are to estimate environmental flow of the Turag...
