For this first postulate, there are different standardized methods from which either precipitation data or flow data could be extracted directly, such as: 1.- Empirical methods.

Which consist of the analysis based on known data UAE Email List such as rainfall in rainfall stations, gauging stations... where depending on the starting data for analysis, precipitation or flow will be obtained, and from these known data obtain the desired data. , and which are represented in the form of a hydrograph or in the form of flow. An example of application for this typology would be the application of Gumbel's method. Illustration 2. Gumbel method. (Source: ResearchGate) 2.- Hydrometric methods. Which consists of the use of a formulation in which known characteristic data of the basin and associated precipitation intensities (precipitation can be obtained from the previous method, or from known applications), flow rates of a specific basin will be obtained.



The standardized method for this type of calculation is called the Rational or Hydrometeorological Method , and can be consulted in instruction 5.2-IC on surface drainage. This is recommended by CEDEX, and included in the instructions of the Ministry of Public Works. These measures involve limiting water consumption to certain municipalities, as is the case of Catalonia, which has limited the water consumption of 150 municipalities to 200 liters per person per day. Also the case of Galicia, where the water has been cut off during the night period, or the water in beach showers, street washing or car washes has been cut off.
