Raw, activated and modified biosorbents for the speciation of C. I. acid red 2 from aqueous solutions: An adsorption study

Adsorptive removal of C. I. Acid Red 2 dye in the aqueous solution has been carried out on the various surfaces. This study describes the comparative adsorption of dye using mustard cakes (MC), sugarcane bagasse ash (SBA) and leaves of water hyacinth (WH) in different forms. The effects of initial adsorbate concentration, contact time, adsorbent dosage, temperature and pH of the medium on the adsorption of C. I. Acid...

Statistical downscaling (Delta method) of precipitation and temperature for Bilate watershed, Ethiopia

It is important to investigate potential changes in temperature and precipitation for assessing the impacts of future climate change on agricultural production for specific regions. In this study, climate scenarios of precipitation and temperature for the bilate watershed were generated. Statistical downscaling techniques of the Delta method analysis protocol of the Agricultural Intercomparison and Improvement...

Flood frequency analysis of River Niger at Lokoja, Kogi State using Log-Pearson Type III distribution

This study applied Log-Pearson Type III probability distribution to model time series annual peak flow records of River Niger recorded at Lokoja gauging station. This was necessitated by the need to provide reliable data for safe and economic hydrologic design for security of lives and property at downstream of river Niger basin. Though several methods have been adopted in the study area for flood mitigation, however,...

Impact of land use/land cover change on hydrologic processes in Dijo watershed, central rift valley, Ethiopia

The aim of this study was to assess the impact of land use / land cover changes on the hydrological process in the central valley basin of Ethiopia, from 1985 to 2018 and evaluate historical land use/land cover change using satellite image. Satellite images were classified by supervised classification technique with maximum likelihood. SWAT model were used to simulate hydrological processes in the watershed. The result...

Indigenous knowledge assessment on irrigation water management practices at Western Showa Zone, Ethiopia

Farmers practices in irrigation water management mostly from indigenous knowledge but the potential of such knowledge is not much understood in terms of irrigation water management in West Showa. Therefore, this study was carried out based on the objective to identify the indigenous knowledge on irrigation water management of the West Showa. The survey was conducted at West Shoa Zone, Dandi, Ambo, Toke Kutaye, Liban...

Assessment of soil and water characteristics and land cover changes along the Tigris River in Baghdad

Land cover changes impact the soil and water quality which are critical for environmental and human health. The goal of this study is to evaluate whether the land cover change along the Tigris River, one of the largest rivers in the Middle East, is causing any heavy metal contamination. The objectives of this study were: (1) To analyze the metal concentrations in the water and soil samples along the Tigris River and (2)...

Impacts and uncertainties of climate change on stream flow of the Bilate River (Ethiopia), using a CMIP5 general circulation models ensemble

The impact and uncertainty of climate change on stream flow of the Bilate River Watershed was assessed. Ensemble of 20 Coupled Model Intercomparison Project Phase 5 (CMIP5) general circulation models (GCMs) under two Representative Concentration Pathways and six GCM structures were selected to form 24 future climate scenarios for the watershed. Soil and Water Assessment Tool (SWAT) model was selected to simulate stream...

Water quality assessment of Ntawogba Stream in Port Harcourt metropolis, Rivers State, Nigeria

Ntawogba stream is one of the natural water bodies that drain the marshy swamp forest water from Port Harcourt municipality into Amadi Creek which empties into the Bonny estuary. Water quality assessment was carried out for three consecutive months (July - September) across three sampling points (upstream, midstream, and downstream). The physical parameters pH, temperature, EC, and turbidity were measured in-situ. The...

City scale water audit of a pilgrimage town in South India

The water need of a religious pilgrimage town in South India would typically be much larger than a regular town where religious  pilgrims  and  ritual  activities  do not add  to the water burden of the municipality. To understand this added water burden, a city scale audit was carried out to estimate the water supply, demand and deficit at Guruvayoor, which is a pilgrimage town in South...
