News Update on Flood April-21

[1] Flood power Channel boundary shear stress and stream power per unit boundary area are very useful concepts in assessing the role of rare, great floods in producing major geomorphic responses in fluvial systems. These variables were determined for the largest known flash floods in small drainage basins and for six historic dam-failure floods, predominantly…

Self-protective Measures against Climate Hazards in Ghana: The Case of Dansoman in the Greater Accra Region

Self-mitigation and adaptation often require conceptual and feasible innovative mechanisms, locally designed with inputs from key stakeholders. Developing prudent adaptation measures for local communities are often time-consuming, and require in-depth analysis due to the complex nature of climate change, encompassing several sectors and external facilitators. In our quest to achieve Millennium Sustainable Development Goal (SDG…

A Model of Storage Changes within the Cretaceous Sandstones of Lokoja Formation. North Central Nigeria

An assessment of storage changes within the Cretaceous sandstones of Lokoja Formation constituting the sedimentary part of Lokoja and its environs was carried out using USGS GSFLOW-1.0 software to investigate reasons for water problems such as drying of streams and failure of wells commonly experienced in the area. Daily meteorological data from year 2001 to…

Biosorption of Cd (II) and As (III) Ions from Aqueous Solution by Tea Waste Biomass

Biosorption of Cadmium (Cd (II)) and Arsenic (As (III)) ions from aqueous solution by tea waste biomass was examined in a batch experimental setup. The effects of pH and temperature on the biosorption were studied in this work. The optimum pH values for the maximum efficiency of biosorption of Cd (II) and As (III) ions…

Temporal and Spatial Variability in Water and Sediment Characteristics of Abule Agege, Abule Eledu, Ogbe, Creeks Adjoining Lagos Lagoon, Nigeria

Lagos lagoon is known to contain a vast number of anthropogenic stressors that resulted from the influx of human activities due to the increase in human population, industries and incursion of contaminants from adjoining thus making the ecosystem highly contaminated. The degree of this contamination can be affected by the seasonal variations in time and…

Recovery of Pure Slaked Lime from Carbide Sludge: Case Study of Lagos State, Nigeria

Carbide sludge is the by-product of reaction between calcium carbide and water in the production of acetylene gas for welding purposes. This by-product is discarded as waste due to high content of impurities as a result of the reactants and reaction processes. In this research work an attempt was made at developing an appropriate process…

Groundwater Nitrate

Groundwater is the main source of drinking water for many small agricultural communities. Nitrate concentration in groundwater is a major problem in Nira River basin area, which is mainly due to the run off or seepage of chemical fertilizers from the agricultural field. A total of 45 water samples were collected in the period of…

Carbon Stocks Potential in Regenerating Trees of the Tropical Coastal Forest Ecosystems

Estimation of carbon in the regenerating tropical coastal forest is needed to support conservation and forest monitoring strategies. This chapter presents the determined carbon stocks in regenerating species across forest sites subjected to deforestation because of crop-farming and livestock grazing. The study used thirty-three independent measurements of tree carbon stocks from thirty-three tree families found…
