Water resources modelling

Services we offer

Water resources modelling is a key part of managing water resources. It provides a temporal and spatial distribution of water in the system. During a drought, these models will tell us which user(s) is suffering the most, and many other more applications.

Hydrological analysis

Hydrological modelling and analysis is the art of obtaining the quantity of water that flows on the surface and that penetrates the surface for potentially recharging groundwater aquifers, using precipitation and evapotranspiration data as input.

Water accounting

Water accounting provides an understanding of the components of water balance in a system. It can tell us how much water comes in and goes out, how much is consumed or lost, how efficient water use is and many more useful information which can be used as a basis of further studies such as conflict resolution.

Supply and demand forecasting

No long-term planning can be done without knowing how much water will be available in the future and how much is going to be consumed. This can be done using various methods and with different temporal and spatial granularity.

Conflict resolution

When competing water users are supplied from shared water resource, it is likely that conflict arises especially during extreme events such as flooding and drought. It can be investigated through the lens of Game Theory and, depending on the level of cooperation among beneficiaries, approaches can be recommended.

Climate change impact assessment

With growing challenges from climate change, it is vital to know its impact on our supply and on our assets. This can be done via climate change modelling which can help us quantify the vulnerability of different components of a given water resources system and the level of risk they face under various climate change scenarios.

Options appraisal

When water deficit is forecasted, decision-makers need to identify options that ensure enough water is secured in short- and long-term. These can include options focusing on reducing water demand and options to can provide a source of supply. The process of identifying such options, technically developing them, and capturing their performance against a set of metrics is labelled as options appraisal.

Investment modelling /decision-making

Following an options appraisal exercise, decision-makers need to understand which combination of options is best to meet their needs, when those need to be made online, what benefits and dis-benefits they bring, and how the deficit profile will be improved. Answer to these questions forms an investment plan which can be obtained through investment models and, more generally, decision-making approaches.
