Civil engineering works are complex, because there are a lot of out of control elements, such as climatic factors (heavy rains, dries, frosts, etc) as natural disasters (earthquakes, hurricanes, etc). However, there are studies or predictions that may help represent the conditions that affect these works and its surroundings, and act accordingly to mitigate these effects. The highest problem in Andalucia is located in the coast environment. However, Seville has also been affected by some important floods. Due to this problem, some action plans have been activated and some structures have been restored. The area, in which this study is focused, is known as Riopudio River, located in the Hidrographic Watershed of Guadalquivir, where some restauration works have been done since 2008. There is a study realized by the Local Government of Bormujos in 2011, in which the strong storms of the last years are not included. That is one of the objective of this study, to analyse the differences of the results between both studies and to update the old ones. On the other hand, nowadays, the contribution of softwares to the engineering is very important, making these studies more reliable on future events predictions. However, the process is very slow and some parameters are not very accurate. Due to that fact, these parameters are analysed in depth in some studies, giving different values to evaluate how the solution changes. In these study, the lag time of the watersheds and the Muskingum parameters have been adjusted to observe the peak flow evolution. As a preview of the results, the peak flow for a return period of 500 years is 110 m3/s. Comparing previous studies, there are some small differences in the results which may be due to the chosen parameters, like Muskingum ones, or the meterological stations data. Finally, some GIS software have been used to represent the concerned area and make maps, spreadsheets have been used for the mathematical and stadistical part of the study, and a flow propagation software called HEC HMS has been used to make some time simulations
