A. Pilot area

The Pilot area is located on the left banks of the Yesil river in the immediate vicinity of the Nazarbayev University campus. The area is currently under development, partially covered by residential blocks but also having still open, bare land. For the simulation works conducted in the TERESA project, the official urban development plan has been digitalised and considered as base scenario for all project simulations. The aim of the modelling at the Pilot area is to estimate the efficiency of sustainable urban development systems (SUDS) in terms of reduction of surface runoff, increase in evaporation and infiltration, reduction of water levels caused by floods in case of heavy rainfall events, as well as impact on groundwater levels in the underlying aquifers.
