Análise da ocorrência da precipitação máxima diária anual na Cidade da Beira

Abstract

The city of Beira, like other Mozambican cities, has been affected in recent years, by diarrheal diseases, mainly by water contamination in communities with blades discovered by floods, total or partial destruction of access roads, water erosion, water loss. cultures, etc. As a result of the occurrence of maximum daily precipitation. The study of the behavior of the maximum daily daily precipitation is fundamental for the understanding of the hydrological processes in a given region, it allows us to have an idea of ​​the maximum amount of precipitation that can occur in a certain place, during a day. The number of days with precipitation, compared to the amount of precipitation, gives us an idea of ​​the destruction of the occurrences of precipitation and its intensity. The quantification of the spatial variability of the maximum daily annual precipitation to which a certain probability of occurrence is associated is a key variable in the design of most hydraulic works. The accomplishment of this work was based on analysis of data of daily precipitation, of two stations of the city of Beira Observatories and Beira Aeroporto. For the analysis of the maximum monthly daily precipitation, the highest daily precipitation value of each month, of each year, of the historical series of the aforementioned stations was used. The analysis of the maximum daily precipitation in the region of Beira was carried out considering the highest daily precipitation of each year in the historical series collected at the stations of Beira Aeroportos and Beira Observatories. The results obtained in the present study may help, in a certain way, in decision-making in various sectors of society. Prior knowledge of the probability of what the rainy season is going to be recommended is recommended, since for a better planned economy it is necessary to use favorable climate conditions.
