Overview

Computational study demonstrates improved daily rainfall time series imputation using maximum overlap discrete wavelet compressed sensing, suggesting robust applications in hydrological modeling.

Key Points

To introduce and assess a dynamic adaptive maximum overlap discrete wavelet-based compressed sensing algorithm for accurately imputing missing daily rainfall time series data.
Analyzed 22 years of validated daily rainfall data collected from five meteorological stations in the Euphrates-Tigris Basin.
Coupled stochastic and deterministic signal components from discrete wavelet (DW) and maximum overlap discrete wavelet (MODW) transforms with compressed sensing (CS) frameworks.
Assessed MODW-CS, DW-CS, and baseline CS models across 50%, 70%, and 90% data availability scenarios using RMSE, MAE, and coefficient of efficiency (CE).
Both MODW-CS and DW-CS models achieved higher prediction accuracy and lower error metrics than the baseline CS model.
MODW-CS consistently outperformed DW-CS across all data availability scenarios (50%, 70%, and 90%), demonstrating superior capacity to capture intrinsic time series dynamics.
