At the construction of 'Maasvlakte 2' in 2012, two sand closures were constructed. Sand is in most cases the most profiting construction material. The processes and the amount of sand losses which occur during the construction of a closure contain large uncertainties. In order to construct a closure, the production of sand has to be larger than the sand losses. The current calculation tool for the sand losses is presented in the 'CUR 157, Sand Closures'. This book presents a feasibility study, but the calculated sand losses show a large uncertainty. For future closures it is demanded to improve the accuracy of the prediction of the sand losses. This thesis contains two goals. Investigate the processes which occur during the construction of a sand closure and construct a tool to calculates the sand losses. In order to perform this research, answer is found to the research question: "How can the processes during construction of a sand closure be described and modeled to improve the prediction of the sand losses over time?" The sand losses are calculated using a one dimensional model which uses the Van Rhee formula to determine the erosion of the bed and banks.
