Geochemical and statistical studies of Mio-Pliocene aquifer’s mineralization in Jerba Island, South-eastern Tunisia
Publication date: Available online 19 March 2019Source: Physics and Chemistry of the Earth, Parts A/B/CAuthor(s): Soumaya Farhat, Mahmoud Bali, Fethi KamelAbstractManagement of water resources is a major concern for arid and semi-arid regions mainly because of the high groundwater salinization which impacts water quality. Here, Hydrochemical data of major and minor ions such as (sodium (Na+), Calcium (Ca2+), Magnesium (Mg2+), potassium (K+), chloride (Cl-), bicarbonate (HCO3-) and sulfate (SO42-) were used to study the Mio-Pliocene (MP) aquifer of Jerba Island, southeastern Tunisia, whose groundwater resources are characte...

Evaluation of TAMSAT satellite rainfall estimates for southern Africa: A comparative approach
Publication date: Available online 20 February 2019Source: Physics and Chemistry of the Earth, Parts A/B/CAuthor(s): Eric S. Seyama, Mhosisi Masocha, Timothy DubeAbstractDeveloping countries with a paucity of direct rainfall measuring systems on the ground, satellite remote sensing is increasingly being relied upon as a means through which national governmental response and future strategies to manage natural disasters, such as drought and flooding are decided upon. The aim of this study was to assess the performance of the Tropical Applications of Meteorology Using Satellite Data and Ground-Based Observations (TAMSAT) mon...

Assessment of Groundwater Vulnerability and Water Quality of Ngwerere Sub-Catchment Urban Aquifers in Lusaka, Zambia
This study is aimed at evaluation of the protection and management of groundwater quality for aquifers in Ngwerere sub-catchment, as a case study. This was achieved through the development of a vulnerability map using inherent hydrogeological and landuse data, as well as analysis of groundwater quality. The results revealed that most of the aquifers in the study area have very low protective effectiveness of the soil and rock cover, which are supposed to act as barriers against pollution. This was validated from physicochemical and microbial analyses of randomly sampled boreholes in the study area, which indicated high lev...

Integrating microbiological and physico-chemical parameters for enhanced spatial prediction of groundwater quality in Harare
Publication date: Available online 11 March 2019Source: Physics and Chemistry of the Earth, Parts A/B/CAuthor(s): Mhosisi Masocha, Timothy Dube, Thokozani DubeAbstractWe predict groundwater quality to ascertain suitability for drinking purposes in the City of Harare using a geostatistical approach. Forty-four (44) groundwater samples collected across different parts of the City of Harare were used. The samples were analyzed for twelve physico-chemical and microbiological parameters (i.e., pH, conductivity, calcium, magnesium, hardness, sodium, iron, potassium, nitrates, sulphates, turbidity, and total coliforms). Then, an ...

Optimization of Urban Land-use Structure in China's Rapidly Developing Regions with Eco-environmental Constraints
Publication date: Available online 12 March 2019Source: Physics and Chemistry of the Earth, Parts A/B/CAuthor(s): Xiang Luo, Xinhai Lu, Gui Jin, Qing Wan, Min ZhouAbstractEconomic growth and eco-environmental protection are largely incompatible in the optimization of the urban land-use structure (ULUS) in rapidly developing regions. Here, we attempted to construct a model for optimizing ULUS with the inclusion of uncertain interval values, simultaneously considering the economic growth and eco-environmental protection in rapidly developing regions so as to estimate the elastic interval value of ULUS. The corresponding urba...

Permeability calculation of rarefied gas flows through 2D porous structures using the lattice Boltzmann method
Publication date: Available online 10 March 2019Source: Physics and Chemistry of the Earth, Parts A/B/CAuthor(s): Michel Ho, Jesús García Pérez, Marcelo Reggio, Jean-Yves TrépanierAbstractIn the perspective of understanding the flow behavior of atmosphere gases through porous thermal protection systems (TPS) for spacecrafts, permeability calculation has been performed by implementing a modified lattice Boltzmann model. This realization allows the simulation of rarefied gas flows through the TPS micro-porous media. Rarefaction, characterized by the Knudsen number (Kn) is taken into account in the Multi-Relaxation Time (...

SDGs and decentralizing water management for transformation: Normative policy coherence for water security in SADC river basin organizations
Publication date: Available online 27 February 2019Source: Physics and Chemistry of the Earth, Parts A/B/CAuthor(s): Christopher Changwe NshimbiAbstractThis paper engages in a normative analysis of water security, in view of the sustainable development goals (SDGs) and the call for transformation. It examines the role of river basin organizations (RBOs) and integrated water resources management (IWRM) to water governance, and the extent to which they are consistent with water security for development in Southern Africa. The paper uses Policy Coherence for Development (PCD) and addresses essential questions regarding the ex...

Geospatial assessment of soil erosion vulnerability in the upper uMgeni catchment in KwaZulu Natal, South Africa
Publication date: Available online 22 February 2019Source: Physics and Chemistry of the Earth, Parts A/B/CAuthor(s): Nosipho Makaya, Timothy Dube, Khoboso Seutloali, Cletah Shoko, Onisimo Mutanga, Mhosisi MasochaAbstractSoil erosion remains a major environmental threat confronting agriculture in South Africa. The main objective of the study was, therefore, to assess and map soil erosion vulnerability in the upper uMgeni catchment of South Africa. To achieve this objective, the Analytical Hierarchy Process (AHP) was used to calculate the normalized weights of six soil erosion controlling factors i.e. slope (27.6%), vegetati...

Perceptions on greywater reuse for home gardening activities in two rural villages of Fetakgomo Local Municipality, South Africa
In this study we assess the reuse of greywater for home gardening in two rural communities (Ga-Seroka and Ga-Nkwana) in Limpopo Province, South Africa, using a mixed methods approach (Qualitative and Quantitative). A total of 95 and 87 households were randomly selected in Ga-Seroka and Ga-Nkwana villages, respectively. Field surveys from the selected households were gathered based on structured questionnaire and then analysed using statistical package software. The key findings of the study showed that 66% of the respondents from Ga-Nkwana village reused their greywater for irrigation, as compared to 59% from Ga-Seroka. Th...
