  • 摘要:The objective of this study was to apply a continuous hydrologic model that uses the Curve Number method to a large undeveloped watershed, calibrate the model and obtain parameter values; and, from the acquired information, to attempt to determine the general applicability of the Curve Number method to large watersheds. The results are generally favorable, with simulated flow results typically close to actual recorded values of flow. The general results of flow simulation are within 8 percent (simulated flow versus recorded flow). Given the number of potential sources of error other than catchment size, these results tend to indicate the appropriateness of the model for use on these study watersheds, as well as its applicability to other large watersheds.
