The collection of information on the achievement of the water related Sustainable Development Goals (SDGs), as well as their analysis through research, is defined as being difficult especially in the absence of data and tools that can model these performances. An analysis of SDG indicators at the level of 2015, for 41 countries where the population has high and medium incomes shows that a special level of complexity in monitoring is given by the fact that each country measures certain indicators specifically, and these cannot be compared. It is recommended to formulate methods of measurement and monitoring that can be compared. All these consistent methods between countries must be subject to data protection rules, both in terms of access to them and in terms of their management. Present paper shows the main challenges in monitoring water related SDGs (mainly 6, 11 and 13) in Romania, what is the status so far and what are the challenges for the future.

Smoothed particle hydrodynamics (SPH) is a Lagrangian mesh free particle method which has been developed and widely applied to different areas in engineering. Recently, the SPH method has also been used to solve the shallow water equations, resulting in (SPH-SWEs) formulations. With the significant developments made, SPH-SWEs provide an accurate computational tool for solving problems of wave propagation, flood inundation, and wet-dry interfaces. Capabilities of the SPH method to solve Saint-Venant equations have been tested using a SPH-SWE code to simulate different hydraulic test cases. Results were compared to other established and commercial hydraulic modelling packages that use Eulerian approaches. The test cases cover non-uniform steady state profiles, wave propagation, and flood inundation cases. The SPH-SWEs simulations provided results that compared well with other established and commercial hydraulic modeling packages. Nevertheless, SPH-SWEs simulations experienced some drawbacks such as loss of inflow water volume of up to 2%, for 2D flood propagation. Simulations were carried out using an open source solver, named SWE-SPHysics.
