“…The radius of rain is of a drop is slightly greater than 250 µm. The pattern and invariably the amount of rainfall are among the most important factors that affect the output of hydroelectric power generating systems [30]. Statistical observations obtained from pattern of these systems are precipitation dependent.…”

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.

“…Yearlong stages also reduce the significance of streamflow autocorrelation and correlation with other indicators such as snowpack measurements. This produces results that are easier to interpret and that more clearly illustrate the impact that differences in surface and subsurface storage have on optimal control and on the benefit of capacity expansion [Oliveira and Loucks, 1997].…”

“…Systems analysis allows managers to identify control policies for new or modified systems for which there is insufficient operating experience to rely on heuristic control methods [Oliveira and Loucks, 1997]. In particular, for conjunctive use, systems analysis can identify control policies that efficiently ration water supplies and allocate stored water between surface and subsurface storage.…”

Abstract. Heuristic or intuitive rules based on experience may not be efficient when applied to the management of water supply systems that contain both surface and subsurface storage. In particular, rules that assign subsurface storage the role of a backup to surface storage do not recognize the different capabilities of surface and subsurface storage. We demonstrate how to incorporate the different capabilities of surface and subsurface storage in appropriately cautious long-term control of conjunctive-use systems. We also demonstrate how these results may be used to evaluate the benefit of adding groundwater supplies to an existing surface water supply system.

“…Nicklow et al, 2010), there has been a lack of uptake by decision makers (Jones et al, 2002;Oliveira and Loucks, 1997). However, there is increasing interest in adopting such tools, particularly in urban water planning, such as discussed in a recent planning exercise at Colorado Springs Utilities in the USA (Basdekas, 2014).…”

Research to date has emphasized algorithmic improvements and individual applications in specific areas (e.g., model calibration, water distribution systems, groundwater management, river-basin planning and management, etc.). However, there has been limited synthesis between shared problem traits, common EA challenges, and needed advances across major applications. This paper clarifies the current status and future research directions for better solving key water resources problems using EAs. Advances in understanding fitness landscape properties and their effects on algorithm performance are critical. Future EA-based applications to real-world problems require a fundamental shift of focus towards improving problem formulations, understanding general theoretic frameworks for problem decompositions, major advances in EA computational efficiency, and most importantly aiding real decision-making in complex, uncertain application contexts.
