Abstract: | Application of integrated hydrological models to manage a watershed’s water resources are
increasingly finding their way into the decision-making processes. The Soil and Water Assessment
Tool (SWAT) is a multi-process model integrating hydrology, ecology, agriculture, and water
quality. SWAT is a continuation of nearly 40 years of modeling efforts conducted by the United
States Department of Agriculture (USDA) Agricultural Research Service (ARS). A large number of
SWAT-related papers have appeared in ISI journals, building a world-wide consensus around the
model’s stability and usefulness. The current issue is a collection of the latest research using SWAT
as the modeling tool. Most models must undergo calibration/validation and uncertainty analysis.
Unfortunately, these sciences are not formal subjects of teaching in most universities and the students
are often left to their own resources to calibrate their model. In this paper, we focus on calibration
and uncertainty analysis highlighting some serious issues in the calibration of distributed models.
A protocol for calibration is also highlighted to guide the users to obtain better modeling results.
Finally, a summary of the papers published in this special issue is provided in the Appendix. |
