![]() The dense river network of hydrometric stations in Luxembourg offers an excellent opportunity to test the proposed tool. The same holds true for the selection of Case study Among all possible infilling methods, the choice of the most appropriate one is not a trivial task. Most of the methods proposed in the literature are based on data transfer from one or more donor stations (gauges) to a target station. infilling missing values.ĭata infilling is a challenging task that has been addressed by previous research work.įor infilling gaps in hydrological time series, classical methods of data analysis have long been applied (Salas, 1980) and recent studies have proposed more efficient techniques (Harvey et al., 2010, Mwale et al., 2012). As a result, hydrologists have access to a collection of usable tools, but they still need to deal with several technical issues (like data wrangling, tuning predictive algorithms) before solving their initial problem, i.e. But most of these tools require some data mining and machine learning expertise, as well as fine-tuning in order to meet user needs and be properly exploitable by end-users (Serban et al., 2013). For instance, specific user friendly software tools are already available or can be developed in platforms like R 1 or Matlab 2 to interpolate missing data and/or address hydrological problems. A consequence of these issues is the need of data infilling methods to reconstruct missing data, when appropriate and before hydrological time series can be used in a number of applications.įrom a technical point of view, a wide choice of data analysis tools is nowadays offered to hydrologists. It also limits the use of such data for hydrological or hydrodynamic model calibration/validation purposes. Specifically, the presence of discontinuities precludes the computation of hydrological statistics and physiographic indices. The existence of gaps results in difficulties in data interpretation and is a large source of uncertainty in data analysis. Missing data in river flow records represent a loss of information and a serious drawback in water management. They are an inevitable consequence of factors such as station maintenance, equipment malfunctioning, human errors, changes in instrumentation and data processing issues (Harvey et al., 2010). Rather, time series of hydrological data are often affected by data gaps, which are discontinuities in the record of data.
