This study was developed to identify the resources and applicable methodology for the delineation of primary flood corridors.
The purpose of the Phase I study is to evaluate existing drainage conditions and to identify alternative flood control/floodplain management strategies which warrant further consideration.
Originally, the purpose of the study was to obtain either a Letter of Map Revision or a Physical Map Revision from the Federal Emergency Management Agency. Unfortunately, during the initial stages of the investigation, it became apparent that FEMA's guidelines for these types of map revisions could not be accommodated, primarily due to flow-distribution conflicts.
This report describes the hydrologic and hydraulic analysis. Development in the lower end of the watershed has occurred without knowledge of the floodplain's characteristics.
The purpose of the study is to identify existing flooding problems for fifteen homes adjacent and west of Holladay Street which have experienced flooding in the past three years. A 1991 follow-up report is included that corrects an error in the earlier report's estimation of the split flow quantities at the intersection.
This report is the first phase of a study to provide a basin management plan for the Tucson Mountain Drainage Basin. Phase II will identify and evaluate alternative specific solutions to flood plain management measures with Phase III accomplishing conceptual designs for the selected alternatives.
Covers an area in southeastern Pima County that drains the Arivaca Creek watershed. The purpose of the report is to estimate peak discharge for the 50 year storm frequency event, utilizing the rational method (Q=CiA). This method pre-dates that outlined in the Hydrology Manual for Engineering Design and Floodplain Management within Pima County, Sept. 1979, and is considered less accurate. It is recommended that this report be archived and discontinued for use for regulatory purposes.
Study of pollen samples from these two Reeve Phase sites was undertaken excluding Cheno-am and Compositae pollen from the pollen sum. Cross-dating suggests a five-horizon pollen sequence; three horizons are evidenced a both sites, the other two are from samples superimosed on the occupation floors of rooms. Dates between A.D. 1375 and 1490 are suggested for the sequence. Also discusses economically significant pollen types and presents cultural ecological interpretations. Published 1973
Pilot study of 9 pollen samples to assess pollen preservation, potential to aid stratigraphic analysis, and recognition of environmental changes.
