The Use of Tape Recordings in Teaching Local History

The problem of the thesis is to develop rationale for the teaching of local history in the schools through the use of recorded documentary statements by eyewitnesses to local events. As illustrative of this mode of teaching local history, a series of recordings are made in which the residents of the Pomona, California, area who were eyewitnesses to the local events or who could relate reliable hearsay about the history of Pomona are interviewed. A research methodology for the taking, editing, and cataloguing of these tape recordings for school use is developed and executed

Using airborne laser altimetry to improve river flood extents delineated from SAR data

Flood extent maps derived from SAR images are a useful source of data for validating hydraulic models of river flood flow. The accuracy of such maps is reduced by a number of factors, including changes in returns from the water surface caused by different meteorological conditions and the presence of emergent vegetation. The paper describes how improved accuracy can be achieved by modifying an existing flood extent delineation algorithm to use airborne laser altimetry (LiDAR) as well as SAR data. The LiDAR data provide an additional constraint that waterline (land-water boundary) heights should vary smoothly along the flooded reach. The method was tested on a SAR image of a flood for which contemporaneous aerial photography existed, together with LiDAR data of the un-flooded reach. Waterline heights of the SAR flood extent conditioned on both SAR and LiDAR data matched the corresponding heights from the aerial photo waterline significantly more closely than those from the SAR flood extent conditioned only on SAR data
