Discharge Monitoring in Open-Channels: An Operational Rating Curve Management Tool [PDF]
Sensors, 2023 An aspect correlated with climate change is certainly represented by the alternation of severe floods and relevant drought periods. Moreover, there is evidence that changes in climate and land cover are inducing changes in stream channel cross-sections ...

Construction of rating curve at high water level considering rainfall effect in a tidal river
Journal of Hydrology: Regional Studies, 2021 Study region: South Korea (KR), Ulsan tidal river. Study focus: Climate change and urbanization pose a serious threat to rising water levels and flooding in the estuary region. In particular, tidal river, which is located in the estuary area, is impacted

Sediment Rating Curve Estimation Using Robust Regression [PDF]
فناوریهای پیشرفته در بهرهوری آب, 2022 A sediment rating curve is the most known method in the hydrological approach for suspended sediment load estimation that is a power equation (or linear equation based on logarithmic data transformation) to relate suspended sediment load to the river ...

DEVELOPMENT OF STAGE-DISCHARGE RATING CURVE AND RATING TABLE OF PIYARO MINOR AND DILWARO MINOR [PDF]
Geological Behavior, 2021 Developing a gauge-discharge relationship in rivers, canals, and minor flow is vital for controlling floods, managing water resources, Spatio-temporal analysis, socio-economic development, and sustaining the ecosystem.

The European Journal of Finance, 2018 This paper explores the extent to which term structure of individual credit default swap (CDS) spreads can be explained by the firm's rating. Using the Nelson–Siegel model, we construct, for each day, CDS curves from a cross-section of CDS spreads for each rating class.

Development of Rating Curves: Machine Learning vs. Statistical Methods
Hydrology, 2022 Streamflow measurements provide valuable hydrological information but, at the same time, are difficult to obtain. For this reason, discharge records of regular intervals are usually obtained indirectly by a stage–discharge rating curve, which establishes

Considering rating curve uncertainty in water level predictions [PDF]
Hydrology and Earth System Sciences, 2013 Streamflow cannot be measured directly and is typically derived with a rating curve model. Unfortunately, this causes uncertainties in the streamflow data and also influences the calibration of rainfall-runoff models if they are conditioned on such data.

Phenomenology of the interest rate curve [PDF]
Applied Mathematical Finance, 1999 This paper contains a phenomenological description of the whole U.S. forward rate curve (FRC), based on an data in the period 1990-1996. We find that the average FRC (measured from the spot rate) grows as the square-root of the maturity, with a prefactor which is comparable to the spot rate volatility.
