Empirical model for estimation of global radiation from sunshine duration of Ijebu-Ode

Empirical models to estimate global solar radiation require the development of a set of equations that relate it to other meteorological parameters and from the monthly average daily value of clearness index and relative sunshine spanning of a period of 5 years, the Angstrom- Prescott model was developed for the estimation of global solar radiation of Ijebu-Ode (Lat. 6.81⁰N. Long. 3.92⁰E), a tropical region of...

Analytical model of heavy-particle pollutant transport in estuary

The aspects of heavy-particle diffusion in the tropical estuary is investigated. The two dimensional advection-diffusion equations with tidal and settling velocity were solved with steady state approximation. An analytic solution was obtained in term of Cosines Integral function. The results showed that the profile of concentration follow a tidal cycle with the concentration decrease when the tidal speed is low and...
