Modelling of Privalul Tinoasa channel, in irrigation system Borcea 2 - Danube Romania

Abstract

The study case is situated in Calarasi County, Romania, near Danube river. The sprinkler irrigation arrangement serves the area of 1018.67 ha, useful, net irrigated area. The sprinkler irrigation arrangement comprises fixed irrigation equipment consisting of 16 central irrigation pivots equipped with nozzle ramps for water spray, the pivots are supplied with water through a network of underground pipes, pumping station, water source the Privalul Tinoasa channel fed from the Danube River The Privalul Tinoasa channel will be cleared and re-profiled, having the role of water accumulation basin that will ensure the aspiration for the designed pumping station. Numerical modelling was performed using the program MIKE11. MIKE 11 is a user-friendly, fully dynamic, one-dimensional modelling tool for the detailed analysis, design, management and operation of both simple and complex river and channel systems. With its exceptional flexibility, speed and user-friendly environment, MIKE 11 provides a complete and effective design environment for engineering, water resources, water quality management and planning applications. The Hydrodynamic (HD) module is the nucleus of the MIKE 11 modelling system and forms the basis for most modules including Flood Forecasting, Advection-Dispersion, Water Quality and Non-cohesive sediment transport modules. The MIKE 11 HD module solves the vertically integrated equations for the conservation of mass and momentum, i.e. the Saint-Venant equations. The input data are: area plan with location of cross sections; cross sections topographical data and roughness of river bed; flood discharge hydrograph. Advanced computational modules are included for a description of flow over hydraulic structures, including possibilities to describe the structure operation.
