 Water and Irrigation Vol.: 11, No. 1: 5-9, March 6, 2020, Spain.

The average annual urine flow in Phase 1 from 1.0 to 10.0 AM of the 2017 investigations in Alicante, Spain was 3.0 ml / min and 0.44 ml / min in Phase 2 from 10.0 AM to 1.0 AM. The climatic factors: temperature relative humidity, barometric pressure and wind speed, generally act jointly on the behavior of urine flow, the most frequent being the combined action of 2 and 3 factors, the least likely is the combination of 4 climatic factors, when a single factor acts the dominant one is the barometric pressure in all its magnitudes. At the same time, the different climatic factors are influenced by the effect of climate change and global warming that cause them to be increasingly unstable and variable. The urine collected during Phase 1 is 1394 ml / day / phase and represents 76.5% of all average urine in 24 hours that is 1821 ml / day, while urine during Phase 2 is 427 ml / day / phase, represents only 23.5% of the total.

From the investigations on the flow of urine and its relationship with the climatic factors that were carried out in Alicante during 3 years, 2017-2019 for the different seasons of the year, which consider winter, spring, summer and autumn, the study of water deficit of the body for values ​​of 1.9 to 2.3 ml / min for the flow of urine and for a normal flow of urine with values ​​greater than 2.9 ml / min, during Phase No. 1 of the investigations.

The climatic factors were taken from AEMET data sources at the Altet Climate station located about 10 km away from where the investigations were conducted, daily evaluating the behavior of the urine and the influential climatic factors: temperature, barometric pressure, humidity relative and wind speed.

The urine collected during Phase 1, from 1.0 to 10.0 AM of the 2017 investigations is 1393.6 ml / day / phase and represents 76.5% of all average urine in 24 hours that is 1820.6 ml / day, while urine during Phase 2, from 10.0 AM to 1.0 AM is 427 ml / day / phase it represents only 23.5% of the total. The contribution of water and milk plus the water contained in 24 hours in the ingested food, plus the additional contribution of water during the heat wave was 2543.7 ml / day for the annual average of the 4 seasons of the year. . The average annual urine flow in F-1 was 3.0 ml / min and 0.44 ml / min in Phase 2, see Table No 1.

Research indicates that in adults, the water deficit and water scarcity in the body, reflect that at that time there is no adequate water supply, so to counteract the adverse effects of increased climate demand, it is necessary normally take about 2 liters of liquid per day during the summer and spring and an additional contribution of 700 ml / day for the water contained in the ingested food: fruits, vegetables, different meats and fish, cereals, grains and other foods. Additionally, more water must be supplied when the waves of intense heat appear during the summer and spring, providing an additional 150 to 200 ml each time the heat waves appear. The diet used was calculated by the balance method based on the recommendations guided by WHO, which was verified during the 2013-2016 period.

Because of the importance of Phase 1 of the urine that represents about 75% of all the urine collected on an average day, the behavior of this phase will be analyzed during the different seasons of the year, which are mainly influenced by the characteristics of the climatic year, the individual and his metabolism, the environment and the daily liquid intake, plus the additional contribution for water contained in the ingested food, plus the additional contribution of water when the climatic demand generally increases by heat wave. During the winter which was characterized by low temperatures, the urine collected during Phase 1 was 1381 ml / day / phase, in the spring the urine evacuated was 1371 ml / day / phase. In the summer there was an increase in temperature and an increase in daylight hours, the urine collected during Phase 1 was 1470 ml / day / phase, in the fall again the average temperature decreased and the urine collected during Phase 1 was 1352 ml / day / phase, see Table Nº 2.

From the analysis of the influence of climatic factors on the flow of urine from 3.0 ml / min which is the most frequent, it is observed that the barometric pressure is the one that has the most influence following the temperature and relative humidity in importance, the one with the least effect was caused by the wind, see Table Nº 3. The climatic factors generally act jointly on the behavior of the flow of urine, the most frequent being the combined action of 2 and 3 factors, the least likely is the combination of 4 climatic factors, when a single factor acts the dominant one is the barometric pressure in all its magnitudes. At the same time, the different climatic factors are influenced by the effect of climate change and global warming that cause them to be increasingly unstable and variable. The results of the 2018 investigations will be announced later.
