GitHub - thodson-usgs/ratingcurve: A Python library for fitting ...
A Python package for fitting hydrologic rating curves. In hydrology, a rating curve is a mathematical relationship between streamflow and water surface elevation (stage). Because stage is much easier to measure than streamflow, almost all streamflow timeseries are generated from rating curves.
The Abuse of Popular Performance Metrics in Hydrologic Modeling
Aug 2, 2021 · Our results highlight obvious (yet ignored) abuses of performance metrics that contaminate the conclusions of many hydrologic modeling studies: It is essential to quantify the sampling uncertainty in performance metrics when justifying the use of a model for a specific purpose and when comparing the performance of competing models.
Performance evaluation of hydrological models: Statistical significance ...
Feb 14, 2013 · In this work, approximated probability distributions for two common indicators (NSE and root mean square error) are derived with bootstrapping (block bootstrapping when dealing with time series), followed by bias corrected and accelerated calculation of …
Ratingcurve: A Python package for fitting streamflow rating curves
Jan 28, 2024 · In this work, we develop a parameterization of the segmented power law that works reliably with minimal data, which could serve operationally or as a benchmark for evaluating other methods. The model, along with test data and tutorials, is available as an open-source Python package called ratingcurve.
Rating Curves Part 1 - Hydro School
In this series of articles, we’ll highlight some best practices and potential pitfalls associated with the “scientific art” of plotting and refining rating curves using measurements, equations, and/or models.
Development of Stage-discharge Rating Curve Using Hydraulic Performance ...
Jan 1, 2016 · In this study, the alternative stage-discharge rating curve was developed using the Hydraulic Performance Graph (HPG). HPG is a plot summarizing all the backwater profile for all possible discharge at a channel reach based on the flow …
Experimental evidence on the performance of rating curves for ...
Jan 1, 2019 · Assessed the performance of rating curve methods at a non-ideal gauging station. Stage-discharge rating curve method is more reliable for monitoring steady flows. Index-velocity rating improves the accuracy of monitoring unsteady flows.
• These curves suggest that projects will attain reference condition for Hydrology and Biotic Structure within 30 years, but not for Physical Structure or Overall Condition (i.e., CRAM Index). 11 • Low scores for Physical Structure are lowering scores for Overall Condition. Buffer and Landscape Setting less applicable
Notebook 2: Rating Curve Development — Engineering Hydrology
Below are rating curve parameters (h0, b, C) that are a simple visual fit to the discharge data. Try changing the values of h0, b, and C to see the effect on how the curve fits the measured discharge data.
Assessing rating curve uncertainty - Taylor & Francis Online
5 days ago · 1 An important consideration in any water resource/hydrology investigation is the uncertainty resulting from the adopted model, the model parameters and the input data (Westerberg et al. 2011). ... and easy to understand procedure to estimate relative uncertainty in daily discharges using stream gaugings and rating curve(s) from which the ...
