Abstract: Computer-implemented methods and computer-readable media are disclosed for processing call-for-service data to facilitate queries and reports to enhance usefulness of call-for-service data. In one embodiment, a computer-implemented method performable by a computer system includes receiving at a computer system data for a plurality of calls-for-service. Individual data for an individual call-for-service includes one or more fields storing information relating to the call-for-service. Based on the information stored within the one or more fields of the individual data, one or more supplemental classifiers are automatically identified. The one or more supplemental classifiers are associated with the individual data. The one or more supplemental classifiers associated with the individual data enable the individual call-for-service to be identified when the one or more supplemental classifiers match one or more specified criteria.

Abstract: Computer-implemented methods and non-transitory computer readable storage media facilitate calculating outflow of water from a selected catchment. A computer-implemented method calculates an outflow of water from a selected catchment is calculated. An identification of a selected catchment from a plurality of catchments within a geographical area is received from a user workstation. A database of multilayered data is accessed, where the data includes hydrological data, geophysical data, and meteorological data for each of the plurality of catchments within the geographical area. From the multilayered data, one or more additional catchments are automatically identified within the plurality of catchments, to identify a group of navigated catchments that drain into the selected catchment. For a given time period, a model is generated determining an outflow of water from the selected catchment and the group of navigated catchments.
