Description

During the INTERREG-project Polder2C's 24 overflow tests were executed on a grass covered levee. Different types of tests were defined, depending on the initial state of the levee cover: Hydraulic tests, damage tests, repair tests and special tests. The dataset contains the general data of all the executed overflow tests.

The dataset contains the following general data for each test executed: overflow test ID, coordinates , purpose of test (hydraulic measurement, damage, repair or special test), goal of the test, pump discharge, width of test section, test duration, key hydraulic parameters (velocity measured at upper and lower slope and calculated terminal velocity) and terminal state of the grass cover at the end of the test.
