Unfortunately there is no consolidated database
AFAIK. The entries are sometimes too generic to be properly identified.
Had to compile a couple of examples for runway excursions on contaminated runways. It ended with specific searches on most of the Nordic countries national accident investigation branches websites.
Another approach to find such accidents and incidents is via the press - search in the renown press archives and then try to find the respective reports.
Also a possible source is to search for studies on aquaplaning, contaminated runways, stopping distance, arresting gear and engineered surfaces. Many studies feature a list of incidents and accidents.
Depending on what the particular aim of the research is this can be helpful. I found about a dozen incidents and accidents which matched my requirements.
