ABSTRACT
This chapter provides results for the sensitivity analysis performed in the Mayaguez Bay Drainage Basin (MBDB) for different hydrologic parameters and rainfall input. Spider plots for percentage changes in peak flow; and runoff depth versus scalar factors were plotted. To identify the parameters for which the MBDB model is most sensitive for the mountainous condition considered, a sensitivity analysis was conducted. Spider plots are used to evaluate the model response to the entire range of the parameter and determine if there is a portion of the parameter range that yields unrealistic results. Variations between methods to fill the gaps between rain gauges produce different responses in flow prediction. For example for the MBDB model, performed hydrologic simulations using the exponential weighted and inverse distance weighted interpolation methods at 200 meter resolution and Next Generation Radar radar level 3 at 2 kilometer spatial resolution with a nominal resolution of 500 meter.
