Hydroelectric power is a renewable source of energy. By principle, hydroelectric power generation relies on the law of conservation of energy where kinetic energy that resulted from the movement of the mass of water from the river is translated into electricity, the quantum of which depends on systemic variables viz: plant efficiency, volumetric water flow through the turbine and the head of the water from the water surface to the turbine. Understanding the dynamics of these variables, and the correlation between them are core to proper planning and management of a hydroelectric power station. In this Study, simple mathematical methods that include linear programming and statistical analysis based on simulation techniques were used to evaluate vital parameters based on the data obtained from the Hydrologic units of the Shiroro Power Stations in Nigeria. The overall aim of the study is to idealize power generation at Shiroro dam in and out of raining season so as to ensure optimum generation of electricity all year round in order to achieve energy sufficiency in Nigeria. The result of the study is encouraging as it supports the viability of the pumped storage system for generating hydroelectric power all year round. The coupling of the hydroelectric power with pumped storage system if properly harnessed could be the needed panacea for the erratic power supply in Nigeria.

Abstracts This paper attempts to put together details of dams' development in Nigeria. Case studies of damrelated incidents were highlighted. A typical case study of Kainji dam safety monitoring assessment was analysed and discussed. From the results obtained it is observed that majority of the piezometer plot of the spillway points to improving stability especially from year 2000 to 2001. The data collected and analysed indicated some displacement of about 25 mm. in some blocks, which shows an abnormal behaviour and require need for closer observations. The tape extensometers reading and the rod extensometer were briefly discussed.

This work developed a reconfigurable Simulink-Autodesk Inventor similitude of multistage processes involved in medium scale urban runoff wastewater treatment plants WTPs. The reenactment approach for wastewater handling is modelled with detailed attention to its fundamental stages. Parameter identification techniques were used for stream improvement processes to realize a flexible and practicable virtual plant. Simulation results were obtained for wastewater treatment in the grit chamber, activated charcoal, coagulation and sedimentation basins respectively. Reduction in sand concentration and the volumetric flow rate of feedstock to effluent are / to . / and / to / respectively. The corresponding sedimentation speed is recorded as . / . The grit filters dry matter from 0.6g/l to 0.048720g/l; to realize 92% reduction of original dry matter in the feedstock. Thus, a prototype framework for input-process-output response analysis of an efficient wastewater treatment plant is developed to guide the design and implementation of new WTPs as well as optimize operations in existing facilities.
