Analysis System

The Information and Modelling Systems are used to explore geographic information and to operates simulations on hydraulic structures without considering different spatial contexts, scenarios or operational measures. Such framework could be performed on the Analysis System. From the selection of the water management problem, the definition of the scenarios as well as the identification of the relevant operational measures, some reference values are established for the actions and variables to be considered in each of the simulation models and infrastructure systems.

In the conception of the Analysis System several concepts are involved: the water management problem (the limitations to accomplish the objectives established for the operation of the hydraulic infrastructures); different environmental scenarios (set of variable values with influence on the analysis problem, determined by uncontrollable external factors); operational measures (anthropic actions, expressed by a set of variables associated with the operation of hydraulic infrastructures and natural systems); spatial context of the problem (extension of territory or water mass on which it is analyzed a particular water management problem); and case management (set of operating situations of hydraulic structures or natural systems framed by scenarios and/or operational measures).

The Analysis System is comprised by different customized applications for the water operational management, each with its own characteristics regarding the management problem, scenarios, operational measures, spatial context of the problem, etc.





CUSTOMIZED INTERFACE FOR THE OPERATIONAL WATER MANAGEMENT

The next figure presents the main view of an Analysis System prototype, concerning to reservoir water levels management problems).

Figure 1

Figure 1 - Analysis System interface (Reservoir water levels).

In this interface is possible from a given scenario (wet year, for example), specify the operational measures (pumping changes, discharges values or opening of floodgates) and proceed with the model execution for these conditions. The simulation results allows to see the behavior of the reservoirs water levels over the time. It's also possible to search for previously simulation results, for evaluate and compare values, under different conditions.

The results can be analyzed not only through tables and chart formats, but also, through animations that cover the entire interval time simulated, showing it instant reservoir water level (Figure 2).

Figure 2 - Analysis System interface (Reservoir water level animation).

The definition of the input parameters is done on the left side panel of the interface. Usually starting by selecting the desired scenario, each one with a specific set of values (Figure 3).

Figure 3 - Analysis System interface: scenario specification.

After the scenario specification, the user must set the operational measures to be applied (Figure 4).

Figure 4

Figure 4 - Analysis System interface: operational measures.

The operational measures may involve for example, changing values of turbinated/pumped discharges, water inflows, water abstraction or gate opening values. For each of these operational measures, specific interfaces are provided so that the user can set their values (Figure 5).

Figure 5

Figure 5 - Analysis System interface: definition of the operational measures.

After the selection of the desired scenarios and operational measures, the user can invoke the remote execution of the model by using the specific button ("Executar").

The interface allows to analyze all the stored results (simulations previously executed). The results list contains an identification of the simulation (usually numerical), the person responsible for the execution of the model and the date on which it was performed (Figure 6).

In the central section of the interface an interactive map is available. This map allows you to check the estimated values on each graphic object, for the selected instant time. By clicking on each graphic object it's possible to consult its values throughout the simulation period.

Some of the represented graphic objects, such as reservoir or hydraulic structures allows you to access to basic reports (Figure 8).

Each of the analysis system interfaces have unique characteristics depending on the water management problem. For example, interfaces related to water levels and discharges on water canals, made available a small animation to allows you to analyze the results over the simulation period.
