DEVELOPMENT OF AN EARTHERN DAM BREAK DATA BASE
Figure 3. Assembled Breach characteristics and time parameters used in the data base
The web application depicts the data base as a set of two-dimensional scatter plots, including a scatter plot display for each possible two-dimensional selection of data base variables, and highlights the positioning of the test prototype data. These displays will demonstrate the possible appropriateness of the global data base in enveloping the test data situation. A common problem in the use of published regression equations can be the lack of a clear depiction as to how well the data used to develop the considered regression equation fits the situation of the test data point. This web applica- tion will provide such a demonstration and may be another useful tool for aid- ing evaluation of earthen dam break assessment.
The project is evolving with the addi- tion of data over time and modification of data base entries if required.
