The use of the MIKE SHE and MIKE URBAN+ (now MIKE+) software to create complex modeling was necessary to understand the behaviour of the natural runoff system of storm water in Tát-Tokod. The complex modeling also provides an engineering solution to develop and improve the current system. This applied solution gives a good basis in understanding the behaviour of the stormwater drainage system and also provides an exploration of the processes happening on the hydrological catchment. The simulation model of the stormwater system allows us to get a detailed view of the capacity of the system, the location and reasons for the issues that surface. The application of simulation approaches that handle the complex flows, both surface and underground, simultaneously give a base for the conceptual measurements with regard to the optimal drainage and retention system.
Calibrated models were prepared, with our MIKE SHE and MIKE URBAN+ (now MIKE+) software which communicate with each other. We have provided the following models:
- Model of sewer system
- Model of storm water collection system
- Integrated model of groundwater and rainfall runoff (catchment)
We have implemented these project parts:
- Calibration of mathematical model of the Tát-Tokod water system, including sewage, stormwater and surface runoff
- Conceptual stormwater plan and planning guide for the collection system of Tát and Tokod’s catchment
- Execution and documentation of complex monitoring campaign
- Simulation of different scenarios of current and future projections in the calibrated stormwater system model
We have provided analyses of the following:
- Evaluation of network capacities — manhole flooding, pressurised pipes, capacity of trenches and pumping stations
- Consultation of actions for the safety of outlets and overflows
- Defining measures for storm water management and retention
Master Plan as methodology
As part of our solution, we used the storm water network of complex Master Plan methodology. The Master Plan methodology is an approach at handling storm water issues, causes and actions in an integrated way. The reason for the use of the digital Master Plan is so that the unique or combined occurrence of different loads and/or measurements can be simulated as individual scenarios. This allows the simulations with the calibrated model, which mimics the real behaviour of the collection system, to give results that help us plan measurements in space and time.
In addition, both the effects of the proposed planned measurements and the effects from the lack of necessary measurements can be demonstrated easily. The results gleaned from the Master Plan can also be used in the planning of the stormwater management and urban management.
