Models have been used by man for thousands of years to control his environment in a favorable way to better human living conditions.The evaluation of hydrologic model behaviour and performance is commonly made and reported through comparisons of simulated and observed variables. he use of hydrologic models has been a widely effective tool in order to support decision makers dealing with watersheds related to several economic and social activities, like public water supply, energy generation, and water availability for agriculture, among others., comparisons are made between simulated and measured streamflow at the catchment outlet. In distributed hydrological modelling approaches, additional comparisons of simulated and observed measurements for multi-response validation may be integrated into the evaluation procedure to assess overall modelling performance. In both approaches, single and multi-response, efficiency criteria are commonly used by hydrologists to provide an objective assessment of the “closeness” of the simulated behaviour to the observed measurements.

Hola,

Además del modelo SWAT como indica Prem Baboo, para aspectos relacionados con el ciclo del carbono, N, P, etc. el modelo LPJ (Lund-Potsdam-Jena model) es bastante aplicado.

Un saludo.
