The representation of physical characteristics differences in watersheds is one of the major challenges on distributed hydrological models application. In this sense, a commonly used technique is the definition of Hydrologic Response Units (HRUs), which are hydrologically homogeneous regions within the basin.<\/p>\n

Here we make available a HRUs map to all of South America. An HRU map is, generally, defined from the combination of soil type and soil use maps, and may also include other variables such as geology and topography. Besides being a particular product to meet hydrological models needs, it reduces input data preparation time. The final map has been used in various applications with the MGB-IPH model. Simulation results with the map were satisfactory in many applications (Fan et al., 2015).<\/p>\n

Important<\/span>:<\/span><\/p>\n

We recommend that the<\/span> map must be<\/span> used with caution<\/span>, always checking<\/span> that the data is<\/span> suitable for the<\/span> study area<\/span>. We do not<\/span> take responsibilities<\/span> for the<\/span> use of information.<\/span> And<\/span> remember<\/span> that this is just<\/span> one more<\/span> information that<\/span> can be used in<\/span> hydrological studies<\/span>, among many available<\/span>. And<\/span> that<\/span> there are always<\/span> uncertainties<\/span> in the data used<\/span> for the map<\/span> derivation.<\/span><\/p>\n

In case<\/span> the map is used for the application<\/span> of the<\/span> MGB<\/span>-IPH model<\/span>, it is recommended to<\/span> check if the<\/span> URH<\/span> water appears<\/span> in the basin <\/span>after<\/span> clipping to<\/span> the basin area<\/span>. If<\/span> URH<\/span> water<\/span> does not appear,<\/span> the user must<\/span> include<\/span> the<\/span> URH<\/span> water<\/span>\u00a0 through some<\/span> GIS<\/span> map<\/span> tool.<\/span> Because the<\/span> MGB<\/span>-IPH model requires that your<\/span> last<\/span> URH<\/span> is<\/span> water<\/span> for the application.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
