Large-scale hydrologic models are being used more and more in watershed management and decision making. Sometimes rapid modelling and analysis is needed to deal with emergency environmental disasters. However, time is often a major impediment in the calibration and application of these models. To overcome this, most projects are run with fewer simulations, resulting in less-than-optimum solutions. In this paper we explain a methodology where a parallel processing scheme is constructed to work in the Windows platform. Parallel processing is implemented in SWAT-CUP (SWAT Calibration and Uncertainty Procedures) using the optimization program SUFI2 (Sequential Uncertainty FItting ver. 2). The problem of scales and particularly the modelling of macro or continental scale catchments in hydrology is addressed. It is concluded that the magnitude of the scale problem is related to the specific hydrologic problem to be solved and to the scientific approach and perspective of the modeller. In this paper, we discuss validation of hydrological models, namely the process of evaluating performance of a simulation and/or prediction model. The performance of two popular watershed scale simulation models – HSPF and SWAT – were evaluated for simulating the hydrology of the 5,568 km2 Iroquois River watershed in Illinois and Indiana. Interactions between humans and the environment are occurring on a scale that has never previously been seen; the scale of human interaction with the water cycle, along with the coupling present between social and hydrological systems, means that decisions that impact water also impact people.
