Regional HydroID
This process will assign a unique regional HydroID for every feature classes within the Geodatabase
The first digit (blue box) describe the Hydrological Region, number 1 for the American side and 2 for the Mexican side
The second two digits (yellow boxes) describe the Sub Region. The basin is divided in 9 sub regions on the American side and 7 sub regions for the Mexican side
The next two digits (red boxes) correspond to the feature class.
Control Point was assigned 01
HydroEdge was assigned 02
WaterBody was assigned 03
Watershed was assigned 04
And so on

WRAPHydro process
*
Center for Research in Water Resources The University of Texas at Austin
Objetivo
The WRAPHydro tools are used to calculate hydrologic parameters as the average precipitation, average CN, drainage area, as well as the length down for the control points identified previously

Future work for this project
Update the Geodatabase when it is required
Time Series related to the control points and main dams will be included in the Geodatabase
