Spectral analysis of base flow separation with digital filters

evaluation of base flow separation methods based on recession analysis

hydrograph analysis is a complex problem in a variety of water resources investigations and its estimate is critical in the assessment of low flow characteristics of river for use in water supply, water management and pollution assessment. the paper describes different methods of base flow separation based recession analysis from daily river flow records and distinguishes the most suitable meth...

Heuristic Continuous Base Flow Separation

A digital filtering algorithm for continuous base flow separation is compared to physically based simulations of base flow. It is shown that the digital filter gives comparable results to model simulations in terms of the multiyear base flow index when a filter coefficient is used that replicates the watershed-specific time delay of model simulations. This way, the application of the heuristic ...

Static Analysis of Digital Filters

We present an Abstract Interpretation-based framework for automatically analyzing programs containing digital filters. Our framework allows refining existing analyses so that they can handle given classes of digital filters. We only have to design a class of symbolic properties that describe the invariants throughout filter iterations, and to describe how these properties are transformed by fil...
