Abortive boreholes and parched wells, ascribed to the difficulty in understanding the hydrogeology of the aquifer by water borehole drillers, pose great concern to the people of the region. Mapping the spatial variability of water table depth (WTD) (m) and aquifer thickness H (m) is a vital step in optimal utilization of groundwater resources. Thus, the aim of this paper is to investigate the spatial variability of the... Read more.

Wetlands are the ecosystems that are found on the interface between land and water. It is also areas of marsh, ponds and swamps, whether natural or artiﬁcial, permanent or temporary, with water, that is static or ﬂowing, fresh, brackish or salty, including areas of marine water, the depth of which at low tide, does not exceed six meters. Although, wetlands by nature are dynamic ecosystems, anthropogenic activities... Read more.

Groundwater vulnerability is an overlay method that is used to determine the ability of pollutants to penetrate the aquifer and harming it. This method helps decision makers by highlighting expected areas to be polluted. In Jordan, groundwater is the main water resource the country uses to match its demand. The groundwater basins in Jordan are divided into 12 major basins; some are rechargeable and others are fossil.... Read more.

A key to future sustenance of human societies lies in the sustainable management and wise use of Wetlands. Wetlands are frequently referred to as Kidneys of Landscape; are amongst the most productive ecosystems on the earth and any alterations might lead to changes in their bio-physical, socio-economic and climatic conditions. Due to various factors like rapid urbanization, industrialization and agricultural activities;... Read more.

Land use/land cover change drive changes in several ecosystem processes over short and long terms. In Ethiopia, the main land use/land cover change involves conversion of natural ecosystem into cultivated land. However, a recent change also involves conversion of cultivated and grazing land into Eucalyptus woodlots. This study was conducted to analyse the effects of such land use/land cover change on soil and nutrient... Read more.

Predictions of the impacts of climate change on the intensity, amount, and spatial and temporal variability of rainfall and temperature are required. The aim of this study was to assess the status of climate change and hydrological response to climate change for Gumara River sub-basin. Statistical Downscaling Model (SDSM 4.2) was used to downscale HadCM3A2a and HadCM3B2a predictors into finer scale resolution. To... Read more.

Legionnaires disease can be acquired through exposure to Legionella pneumophila, a gram-negative bacteria ubiquitous in both natural and engineered water systems. Over the years, a number of disinfection techniques notably, chlorination, ozonation, thermal, UV and copper-silver ionization have been employed across different kinds of engineered water systems with diverse measures of success. Available evidence portends,... Read more.

Increasing greenhouse gas concentrations can cause future changes in the climate system that have a major impact on the hydrologic cycle. To realize and predict future climate parameters, the Atmosphere-Ocean Global Climate Models (AOGCMs) are common employed tools to predict the future changes in climate parameters. The statistical downscaling methods have been applied as a practical tool to bridge the spatial... Read more.

Public perception of bottled drinking water as the cleanest and safest source of drinking water in the world and particularly Ghana, has led to their increasing demand though being pricey. In this study, we present the results of the health-related trace elements (As, Cd, Cu, Pb and Zn) in 10 selected popular bottled drinking water brands sourced from Accra metropolis, Ghana. These include BonAqua Premium drinking... Read more.

This study was carried out to determine the magnitude to which Community Led Total Sanitation (CLTS) approach leads to improved sanitation and its potential threats to groundwater quality and health of people. A comparative study was carried out between eight CLTS and non CLTS villages to measure the outcomes of CLTS approach. Water samples were collected to assess the level of contamination in groundwater sources near... Read more.

Wastewater from a mahewu processing plant was collected for characterisation and jar testing using Ferrifloc 1820 and a combination of Ferrifloc 1820 and the polyelectrolyte Magnafloc. Treatment showed that Ferrifloc 1820 caused a statistically significant decrease on both the chemical oxygen demand (COD) and oil and grease content of the wastewater. The mean decrease for the COD using Ferrifloc 1820 was 65.24%... Read more.

Two models for raindrop growth in clouds are developed and compared with an interpretation to elucidate the rain drop relationship among both the models. A continuous accretion model is solved numerically for drop growth from 20 to 50 microns, using a polynomial approximation to the collection kernel, and is shown to underestimate growth rates. A Monte Carlo simulation for stochastic growth have also been implemented to... Read more.
