Differentiable, learnable, regionalized process-based models with physical outputs can approach state-of-the-art hydrologic prediction accuracy

no code implementations28 Mar 2022 Dapeng Feng, Jiangtao Liu, Kathryn Lawson, Chaopeng Shen

Without using an ensemble or post-processor, {\delta} models can obtain a median Nash Sutcliffe efficiency of 0. 732 for 671 basins across the USA for the Daymet forcing dataset, compared to 0. 748 from a state-of-the-art LSTM model with the same setup.

A Robust Statistical Analysis of the Role of Hydropower on the System Electricity Price and Price Volatility

no code implementations4 Mar 2022 Olukunle O. Owolabi, Kathryn Lawson, Sanhita Sengupta, Yingsi Huang, Lan Wang, Chaopeng Shen, Mila Getmansky Sherman, Deborah A. Sunter

Hydroelectric power (hydropower) is unique in that it can function as both a conventional source of electricity and as backup storage (pumped hydroelectric storage) for providing energy in times of high demand on the grid.

The data synergy effects of time-series deep learning models in hydrology

no code implementations6 Jan 2021 Kuai Fang, Daniel Kifer, Kathryn Lawson, Dapeng Feng, Chaopeng Shen

We hypothesize that DL models automatically adjust their internal representations to identify commonalities while also providing sufficient discriminatory information to the model.

Prediction in ungauged regions with sparse flow duration curves and input-selection ensemble modeling

1 code implementation26 Nov 2020 Dapeng Feng, Kathryn Lawson, Chaopeng Shen

While long short-term memory (LSTM) models have demonstrated stellar performance with streamflow predictions, there are major risks in applying these models in contiguous regions with no gauges, or predictions in ungauged regions (PUR) problems.

From calibration to parameter learning: Harnessing the scaling effects of big data in geoscientific modeling

no code implementations30 Jul 2020 Wen-Ping Tsai, Dapeng Feng, Ming Pan, Hylke Beck, Kathryn Lawson, Yuan Yang, Jiangtao Liu, Chaopeng Shen

The behaviors and skills of models in many geosciences (e. g., hydrology and ecosystem sciences) strongly depend on spatially-varying parameters that need calibration.
