Hello,
Please i have a question about satellite data, i work on hydrology modeling particularly on flood modeling i need some satellite that recorded historical precipitation and flow measurements thank you.

Hi Myriam,
In the last years I worked on this topics so I can suggest my studies on the use of satellites for the hydraulic model calibration and for river discharge estimation. Specifically, for the calibration of an hydraulic model I used
- SAR images (http://dx.doi.org/10.1002/hyp.9550)
- altimetry products (http://dx.doi.org/10.1061/(ASCE)HE.1943-5584.0001018; http://dx.doi.org/10.1016/j.rse.2014.04.007; https://doi.org/10.1016/j.advwatres.2017.11.027)
for the estimation of river discharge I used optical sensors and radar altimetry and some example are listed below:
- http://dx.doi.org/10.1016/j.rse.2017.04.015
- http://dx.doi.org/10.1109/JSTARS.2014.2320582
- http://dx.doi.org/10.3390/rs5094145
- http://dx.doi.org/10.1016/j.rse.2013.04.010
For the rainfall have a look on this:

Hello, you can use this site , https://globalweather.tamu.edu/, it is global site, contains all the data climatic, precipitation, temperature, wind, humidity and solar, these are daily and long series data .
cordially
Hi... I also work on the same domain. Please look the following Data Sources
https://pmm.nasa.gov/data-access/downloads
https://pmm.nasa.gov/data-access/downloads/gpm
https://pmm.nasa.gov/data-access/downloads/trmm
Based on your availability of ground data and forecasting using satellite rainfall products you can choose products like early, late and final run. For inundation area assessment and decision making for headworks you can use final run products. For forecasting you can use early run products and you have to correct the bias using your realtime ground stations. Forecasting using this data will be helpful only for larger basins, Please explore IFAS(Integrated Flood Analysis System).
If you are good in highlevel languages you can try WRF forecasts.
Thank you for all your answers and suggestions it's really nice of you, for those who asked me about my study area: it is in north Africa more precisely Morocco, in the watershed of Tensift and Moulouya.
Hi Myriam,
I think the next link will be very helpful:

Hi,
Regarding precipitation (which is the main forcing for terrestial water cycle), I believe that validation is important before application, not only by just comparing the data with observed time series (with raingauge data or hydrological modelling) but also comparing certain features of the time series is important.
We publish this short article in a early career journal evaluating two P global products recently produce making the assessment with some precipitation indexes.

Hi
If you use Precipitation from remote sensing products, you can improve their performance using local raingauges. The merging algorithm described in this work have proved to be successful in reducing the remote sensed field error. In the paper the parameters of the merging are analyzed against the raingauges density so that one defines their value with the features of the local raingauge network and, therefore, one will not need to perform a calibration procedure.

Hi. Or extent the time frame of data that you have. Want to improve the performance of your hydrological model on a scarce data basin?!! We introduce you to our new article where a satellite-reanalysis-gauge merging algorithm is detailed.
