Ultrasonic flowmeters and data loggers were installed in the main water supply pipes in bathrooms and kitchens on the roof of a three-apartment housing complex in Kuwait. Water consumption patterns were remotely monitored for nine months using data loggers that transmitted information every 5 s.

According to the results obtained, the average daily per capita water consumption was 238 L. Furthermore, black water, light greywater, and dark greywater represented 9 %, 50 %, and 34 % of the per capita water consumption, respectively. Additionally, the leaks and unclassified volumes of water used were 1 % and 6 %, respectively.

This map would enable farmers to monitor their fields more precisely and with greater detail. The research commenced by conducting direct soil measurements and capturing crop spectra using drones equipped with multispectral cameras. The collected data was then mosaicked, processed, and combined with crop yield data to create a set of samples. Machine learning algorithms were employed to make predictions, and the yield projections were integrated into spatial maps. These maps can be utilized for navigation and to track areas anticipated to experience yield changes. The result is a spatial map model that serves as a tracking and navigation system, empowering farmers to monitor crop yield changes effectively.
