Our research group has been involved with many studies regarding Amazon River Basin in the last years. Among them, the development of a hydrodynamic model of the whole basin, where MGB-IPH hydrologic module was coupled to a full Saint-Venant hydraulic propagation module in the lower reaches and Muskingum-Cunge routine in the upper ones, with the implementation of floodplains as storage areas into continuity equation.
Here, we make available the results of the model, providing a distributed discharge dataset for the basin.
Within the model, Amazon basin was discretized into 5765 catchments, and the model calculates one discharge time series for each river reach (related to one catchment each).
In the link below, you will find a text file containing all these calculated time series. Data are arranged as 5765 columns, representing one river reach each, and 4383 rows, representing one day-step each. For these data, the model was run from 01/01/1998 to 31/12/2009, forced with TRMM precipitation and CRU climate data.
In the next link you can find a shapefile containing the discretized drainage network, with 5765 reaches. In the attribute table, the column “MINI” indicates the number of the catchment, related to the column order in the text file above. Then, if you want to know the discharge series in the catchment with “MINI” number 1500, you just need to extract the 1500th column from the text file. Other information in attribute table are (i) upstream drainage area of the reach outlet (km²) and (ii) reach length.
Finally, we created average data files:
- Climatology data for each river reach, calculated from 1998 to 2009. It contains 5765 columns (one per reach) and 12 rows (average discharge values, from January to December). Download climatology data file here.
- Monthly data for each river reach: one time series per month, from Jan/1998 to Dec/2009 (144 months). It contains 5765 columns (one per reach) and 144 rows (one per month, starting in Jan/1998). Download monthly data file here.
The model was validated against many datasets, including in-situ observed discharge and water level, radar altimetry, GRACE TWS and flooded area extent.
It is important to notice that it is a model run, with the assumption of many hypotheses that must be understood before using the data.
Also, in the figure below you can find a map with model efficiency calculated with model results and discharge observed data. For more detailes please read the paper mentioned below.
