Stationarity analysis of the lowlands in the Adour-Garonne basin

This data layer provides trends in the evolution of flow rates and annual flows at the top of the watershed over the period 1968-2020 through several hydrological indicators (QA, QMNA, VCN10, start date and center of the low) at 56 hydrometric stations in the Adour-Garonne Basin which are part of the reference network for the monitoring of drawbacks (RRSE) and selected for their character little influenced by anthropogenic uses.

This data is required for the SDAGE scoreboard for the indicator “Past evolution of natural flows, observed at low”.

The basic data are:
— The flow rates measured at the 56 hydrometric stations of the CSR selected for the study
— The application of a modified version of Mann @-@ Kendall’s statistical test and the Sen estimator

Purpose: Construction of the SDAGE dashboard for the indicator “Evolution of natural flows, observed at the low”.
