Abstract: Provided herein are systems and methods for improving water usage efficiency. One embodiment includes receiving water usage data associated with a building unit over a period of time, where the building unit includes a first plurality of water fixtures that are monitored by the first monitoring device, determining a leak benchmark for the first plurality of water fixtures, and determining whether the water usage data meets the leak benchmark for the first plurality of water fixtures. In some embodiments the method includes in response to determining that the water usage data meets the leak benchmark for the first plurality of water fixtures, determining that a water leak is occurring in the building unit, analyzing the water usage data to determine a likely water fixture of the first plurality of water fixtures that is experiencing the water leak, and reporting data related to the water leak to an administrator.

Abstract: Method of estimating azimuthal amplitude gradient is disclosed. This method uses a correlation of seismic attributes within a sliding volume of data to obtain azimuthal gradient.
