This code contains deep learning code used to modeling hydrologic systems, from soil moisture to streamflow, from projection to forecast.

This released code depends on our hydroDL repository, please follow our original github repository where we will release new updates occasionally https://github.com/mhpi/hydroDL

Examples

The environment we are using is shown as the file repoenv.yml. To create the same conda environment, please run:

conda env create -f repoenv.yml

Activate the installed environment before running the code:

conda activate mhpihydrodl

You can also use this Environment Setup_Tutorial.pdf document as a reference to set up your environment and solve some frequently encountered questions. There may be a small compatibility issue with our code when using very high pyTorch version. Welcome to contact us if you find any issue not able to solve or bug.

Several examples related to the above papers are presented here. Click the title link to see each example.

1.Train a LSTM data integration model to make streamflow forecast

The dataset used is NCAR CAMELS dataset. Download CAMELS following this link. Please download both forcing, observation data CAMELS time series meteorology, observed flow, meta data (.zip) and basin attributes CAMELS Attributes (.zip). Put two unzipped folders under the same directory, like your/path/to/Camels/basin_timeseries_v1p2_metForcing_obsFlow, and your/path/to/Camels/camels_attributes_v2.0. Set the directory path your/path/to/Camels as the variable rootDatabase inside the code later.

Computational benchmark: training of CAMELS data (w/ or w/o data integration) with 671 basins, 10 years, 300 epochs, in ~1 hour with GPU.

2.Train LSTM and CNN-LSTM models for prediction in ungauged regions

The dataset used is also NCAR CAMELS. Follow the instructions in the first example above to download and unzip the dataset. Use this code to test your saved models after training finished.

3.Train a LSTM model to learn SMAP soil moisture

The example dataset is embedded in this repo and can be found here. You can also use this script to train model if you don't want to work with Jupyter Notebook.
