Diversification in Measurement Methods for Determination of Irrigation Water Quality Parameters

Environmental Study on a Coastal River of Bangladesh with Reference to Irrigation Water Quality Assessment: A Case Study on Shailmari River, Khulna

“…Being the prime mover of life on earth, water plays a vital role in sustaining the human race, socio-economic development and the endurance of ecosystem from the medieval time [1]. The quantity and quality of water supply system is eminently indispensable for irrigation scheme, as it is considered to be one of cardinal demands and benefactors in world economy [2]. Researches on irrigation water quality and its response on soils and agriculture around the world agree that irrigation water straightly supremacies the quality of soil and the crops grown on that soil [3]- [5].…”

“…Researches on irrigation water quality and its response on soils and agriculture around the world agree that irrigation water straightly supremacies the quality of soil and the crops grown on that soil [3]- [5]. The escalating demand of agricultural land and products as a function of population growth from the past century has created disparaging situation for water resources, particularly by unplanned and haphazard industrialization and urban sprawl accompanied by diminishing resource over extraction [2]. Besides, salinization of the surface water has emerged as the limiting factor in agriculture that depends on application of irrigation water.…”

“…Being an irrigated-agriculture based country, Bangladesh depends on adequate water supply from both groundwater (80.60%) and surface water (19.40%) of usable quality [9]- [11]. Bangladesh possesses around 5,049,785 ha land area under irrigation, which needs intended quality water for safeguarding the growth and yield of crops producing in it [2] [12]. Usually surface water is been trusted by farmers as a prime source of irrigation due to its availability and cost effectiveness for irrigation purposes which has been threatened in many ways additionally with the upward withdrawal of fresh water in upstream in the dry period and subsequent encroachment of saline water towards the inland from the Bay of Bengal during this period [13] [14].…”

Assessment of Groundwater Quality in a Tidal River Basin of the Ganges Delta in Bangladesh

“…To achieve the analytical insights and accuracy during the study period, the charge balance between cations and anions were found within ±10% by repetitive analysis after calculating the ionic balance errors (Vyas & Jethoo, 2015;Hounslow, 1995). The analytical results exhibited inclusive hydrochemical variation among the seasons throughout the study period.…”

“…In developing countries, anthropogenic factors, geological structure and mineralogy of both watersheds and aquifers play a substantial role in controlling the ground water quality (Drever, 1988;Apello & Postma, 2005;Bahar & Reza, 2010). Being an agro based country, Bangladesh possesses 5,049,785 ha agro-arable land which depends on adequate water supply from both groundwater (80.60%) and surface water (19.40%) of usable quality (Shahid et al, 2006;Hasan et al, 2007;Vyas and Jethoo, 2015;Islam et al, 2016). Usually, ground water is a critical concern in coastal Bangladesh as the people in this region are highly reliant on it for sustaining their livelihoods (Hasan et al, 2013).…”
