What is systems analysis?
Published on: 29 February 2016
Ludovica Beltrame from WISE CDT discusses systems analysis for water management.
Systems analysis is the breaking down of a system into simpler parts and studying how they interact to comprise the whole. This is done through modelling – a model is a simplified representation of a system with inputs, an internal system with constraints, and outputs. Analysis of system behaviour can be used for simulations, forecasting and optimisation, supporting water management decision making.
Water systems are complex. They are affected by human impacts and natural changes and have multiple components, processes, stakeholders and objectives. Systems in water management include irrigation water supply, hydropower, municipal water supply and flooding. Water systems can be analysed by testing a model to optimise objectives.
