Abstract: Droughts are part of extreme meteorological phenomena that generate serious social, economic and environmental consequences. This study seeks to characterize the historical (1976-2019) and projected (2021-2050) meteorological drought in the Niger River Basin in Benin. To achieve this, the present study used daily rainfall observations and simulations of two regional climate models (RCM) (HIR... PubDate: Sat, 30 Apr 2022 00:00:00 +010
Abstract: One of the most important effects of acidic rainfall is on the soil. It can affect other environments such as surface water and groundwater, plants and animals. In this study, to investigate the sensitivity of the runoff and sediment production of Gachsaran Gypsum Formation to acidic rainfalls and its density change, parts of Gypsum Mountain watershed the area in Izeh Township in Khuzestan p...

Abstract: Many rural households do not have access to treated drinking water. However, some households may be in regions where a water treatment plant has excess capacity to supply some additional households. In such circumstances, small diameter low-pressure supply systems can be connected to major transmission lines to give these households access to water. These typically occur in locations that do...

Abstract: To improve water supply services in Port Sudan City (Sudan), a dam with storage capacity of 16 Mm3 was established at the upper gorge of the Khor Arbaat catchment area, which generates runoff that contributes to the sedimentation of the dam at an average rate of about 6% annually. At present (2021), the storage capacity of the dam is reduced by 69% of its original design capacity. Without in... PubDate: Mon, 28 Feb 2022 00:00:00 +010
Abstract: Climate Compatible Development (CCD) is an emerging development approach which seeks to minimize the threat posed by climate change while maximize the opportunities for development. In view of the adverse impact of climate change on the general development of the country, Ethiopia, a number of polices which constitute climate change mitigation and adaptation strategies have been adopted and ...

Abstract: In areas where conventional sewer systems are not possible, innovative and low-cost methods are needed to get rid of pathogens in human urine. Treatment through acidification is a reliable method. In this study, the effect of fresh cabbage waste, potato peel, and teff flour water as substrate for lactic acid treatment of source-separated urine was investigated. Laboratory scale batch experim... PubDate: Thu, 30 Sep 2021 00:00:00 +010
Abstract: The study aims to utilize the NRCS-CN and remote sensing methods in estimating streamflow of Okhuwan and Okhaihe catchments. Remote sensing data, coupled with GIS techniques were used to estimate seasonal rainfall and streamflow. Measured rainfall data was collected from the Nigerian Meteorological Service, while field measurement of streamflow was carried to generate baseline data. Measured...

Abstract: The objective of this work is to characterize the quality of drinking water in the city of Mao and its surroundings. This study is based on 20 water samples collected in the city of Mao and its surroundings between 2018 and 2020. The parameters considered are the physicochemical parameters (pH, T, Electrical conductivity), major chemistry and bacteriological. The chemical analysis made it po...

Abstract: Over the past few years, water quality has been threatened and is vulnerable to various pollutants and climate variables. The deteriorating state of water resources/bodies has been further exacerbated by the impacts of climate change patterns in Southern Africa. Therefore, modelling and predicting the quality of water in sub-basins has become important in controlling water pollution. Remote ... PubDate: Mon, 31 May 2021 00:00:00 +010
Abstract: Treatment of effluents from batik producing enterprises to removal dyes and other impurities is inevitable as these enterprises are becoming ubiquitous in many cities in Tanzania. Wastewater from batik production processes are discharged haphazardly without treatment. In this study, preliminary results on adsorption potential of defatted Moringa oleifera crude seed extract (DMOCSE) and fuel ... PubDate: Fri, 30 Apr 2021 00:00:00 +010
