The software of the program consists of conditions based on thresholds, distances, and a counter. The first question is whether the vehicle is moving. This is where the accelerometer detects its movement using the Cartesian plane of *x*, *y*, and *z*. In the process diagram, in **Figure 18**, the first step is to detect if the water level is high. If the level is low, it shall keep checking if there is any change. If not, the vehicle shall proceed to check if the vehicle is in motion. If the car is in motion, then the text message alert will be disabled, and the client will be alerted through an audible notification. On the contrary, a text message will alert the client. Once the movement is detected, and the condition is established, a text message will be sent to the web server email containing the coordinates. The data is processed, and the web service extracts the coordinates from the email. After extracting the coordinates, a signal is made on the map shown on the web site where there are flooding areas.

Based on historical data and remote sensing technology, research on atmospheric characteristics and environmental effects of UHI has been conducted in the city of San Juan, Puerto Rico, providing a theoretical reference that evidenced the increment of UHI in the capital city. Based on analyses of temperature, solar radiation, evapotranspiration, and albedo data, it was found that the city of San Juan, Puerto Rico, is the most representative zone where the UHI is present in the last 20 years. The consequences of this effect have increased more rapidly in the last 10 years. In conclusion using high-albedo materials and pavements, having green vegetation and green roofs, implementing urban planning, and preserving pervious pavements, shade trees, and water bodies in city areas are the potential UHI mitigation strategies [19]. When urban planning is mentioned, a flood alert system is included. This paper represents the first time that water level technology has been used for hydrologic analyses, specifically for flash floods which are events caused by
