The future of climate lies on the hand of individual who is an active member that contributes input in the biosphere. The amount of climate change will largely influence the water flow in the river through the emission of solar radiation, increase in temperature, heat-trapping gases. There is a need to control pollution, flood hazard, check water quality and monitor sediments and water flow in the drainage basin. Soil and Water Assessment Tools SWAT is one of the best methods of the application being used for hydrologic assessment as well as monitoring events that occur in the catchment studies. Mitigation can simply determine how to reduce the human hazard, in controlling the climate change that affects water flow in river Terengganu. The Soil Water Assessment Tool (SWAT) provides the simulated rainfall from 1973 to 2017. The precipitation and other weather parameters were used for the purpose of this study and the resultant effect is the production of predictive flood hazard event within the catchment area of Kuala Terengganu.

We study the nonlinear parabolic Fisher’s equations for travelling wave solutions. The analyses focus on to describe the analytic solution in the spatial pattern of travelling wave solutions; especially the solutions are characterized in invariant with respect to translation in space. There are two phases in the work: in the first stage, we analyze dimensional reaction-diffusion equation with logistic type growth while in the second phase the non-dimensional equation known as Fishers’ equation is studied numerically. To investigate the results numerically, we select the explicit-implicit finite difference method (FDM) and the approximate solutions are compared with the exact solution in different time steps.

In this paper, we have analysed the non-Darcy MHD flow of a Casson fluid over a nonlinearly stretching sheet in a porous medium. In the mathematical model, using similarity variables, the momentum equation is transformed to non-dimensional ordinary differential equation. And then it is solved numerically using bvp4c method, a Matlab in- built bvp4c-programm. A discussion for the effects of the parameters involved on the boundary layer thickness and the magnitude of the velocity and skin friction has been done graphically and numerically using figures and tables.

Port Harcourt acquired the name “Garden City” for its neatness, beauty, organisation of the buildings and well constructed road networks across the entire city; but this once beautiful city has been overtaken by garbage. Hence, the objectives of this study were to find out why the solid waste management strategies employed by the Rivers State Waste Management Agency  and their contractors are not working and provide best solutions in curbing the challenges militating against solid waste management of the city. Purposive sampling technique was used to determine the sample. Because of the time constraint and the wide area of coverage for this study; 10 areas consisting of 10 communities were selected based on their size, popularity and centrality. Oral interviews and field observation were the methods of data collection and the data obtained through oral interviews were analysed through simple coding, groupings, re-writing, transcribing and interpretations. The results revealed that the solid wastes generated are uncontrolled due to overcrowded settlements; an uncultured way of living of the residents; lack of the needed man-power and technology on the part of the solid waste contractors. It was also revealed that the Government do not carry out proper monitoring and uses unskilled and unqualified persons to carry out their jobs. It was concluded that to adequately clean up the city of Port Harcourt, the Government should stand up to their responsibility of keeping the city clean and sensitize the people on the need to package and dispose of their waste properly.

The study examined the contributions of adult vocational education programmes to community development in Gokana and Khana Local Government Areas of Rivers State. Adult Vocational education programmes as a practise, is an important element that should not lacking in the community; as the adults constitute the functional human element of the society. Four research questions were used to guide this study. The population of the study was 2822 consisting of members of the unions and associations, of which a sample of 1975 members were drawn from the population. The instrument for data collection was structured questionnaires and the collected data were analysed using simple frequency distributions and mean scores. The findings of the study revealed that adult vocational have contributed to the development of the communities, increase productivity, increase in family income, and self reliance. The study recommends that more vocational education centres should be in all the communities in Gokana and Khana, in order for everyone to benefit from the self-sustaining venture and the participants should adopt the method of each one, teach one.
