There is now an opportunity to combine these products to construct actionable water quality forecasts. To that end, we couple streamflow forecasts from the NWM to a gradient-boosted decision tree algorithm (LightGBM) trained on 5+ years of high-frequency monitoring data to forecast in-stream turbidity levels in the Catskill Mountains, NY, USA. Results indicate LightGBM models are capable of relatively skillful predictions, which enable robust forecasts for 1–3 days lead times. LightGBM models offer improvements over a simplified linear model across the entire forecast horizon, and more spatially complex models are more resilient to error at shorter lead times (1–3 days). Moreover, interpretation of model features emphasizes high flows as a driver of turbidity in the region. Results suggest that interpretable, flexible, and efficient machine learning algorithms can produce capable water quality forecasts from streamflow forecasts and expand understanding of process dynamics.

In addition to streamflow, the NWM outputs other hydrologic variables including soil moisture. Soil moisture plays a key role in simulating seasonal hydrologic processes in process-based models; therefore, it is imperative to evaluate models against observed data. However, incorporating in situ observed soil moisture data, which is highly spatially variable, into the calibration process may compromise streamflow results. We investigate how model evaluation, including in situ soil moisture observations, affects CFE's ability to reproduce streamflow and soil moisture. We evaluated the CFE model on two experimental watersheds using both traditional and signature-based performance metrics for soil moisture. Results showed that including soil moisture data enhances the reproducibility of overall and seasonal soil moisture patterns without sacrificing the reproducibility of streamflow.

In this paper, we examine water use values across users in the arid water-scarce region of South-Central Texas, as a case study, using a mix of market and nonmarket valuation approaches. This mix of methodological approaches provides results based on actual purchases, comparable sales, land rental rates, source replacement, and water-conserving investment. Our results show considerable differences among sectoral water use values, with the lowest in agriculture and the highest for municipalities, and energy fracking.
