PEREZ-NIETO, Samuel et al. Determination of runoff in Huixtla, Chiapas basin, by the Nc method and using GIS, TAM and NB10. Rev. Mex. Cienc. Agríc [online]. 2014, vol.5, n.6, pp.979-990. ISSN 2007-0934.

It was determined the runoff volume Ve for 53 sub basins of Huixtla Basin from Mexican Coasts of Chiapas, corresponding to precipitation of Tropical Storm Stan occurred from October 01 to 06 2009, using the distributed and added models, using the concept Nc curve number and retention parameter Sr defined by the United States Department of Agriculture (USDA), and applying map algebra techniques (TAM), Geographic Information Systems (GIS) and the algorithm number base 10 (NB10); which is proposed to associate the characteristics that depend on Nc; for this was generated a table with present land use in the basin, defining the NB10 from 1 000 to 13 000, another for the types of hydrologic conditions to which are associated the NB10 multiples of 100 (100 for good, 200 for Regular and 300 for poor) and a third for hydrological groups that were assigned NB10 multiples of 10 (10 for group A, 20 for B, 30 for C and 40 for D). From the results of the runoff volume for sub-basins (Vec), by the distributed model and the aggregate model, it is observed that the differences between the two methods are minimal, on the order 1.07% of the average; the runoff volume (Ve) for the Huixtla Basin, calculated by the distributed model was 301 229 025 m3 (equivalent to Le= 0.847 m) and the aggregate model of 304 115 519 m3 (corresponding to Le= 0.856 m), which implies a difference of 0.97% and means that both models, used with GIS, TAM and NB10 techniques, practically provides the same results, so it can be used either one or the other interchangeably.
