Although I know there are some scientists who know a great deal outside their own specialty, I also know that it is somewhat disingenuous to quote the typical hydrologist on evolution and then pronounce that his (or hers) is a "scientific" opinion of evolution.
That's like quoting the typical gynecologist on heart surgery and then declaring that hers is a valid opinion of heart surgery because she's a doctor. Wonderful!
She might know enough to give a valid opinion on heart surgery -- after all, anything is possible -- but the odds are frankly against it. So too the odds that a hydrologist has kept up with the evolutionary sciences well enough to be called an expert in them.
Courts of law have standards of proof that are well below the standards of science, but not even a law court would allow a hydrologist to serve as an expert witness on evolution without convincing proof that s/he was competent in the evolutionary sciences. The tendency of Creationists to simply assume that all scientists know enough about evolution to be experts in it is merely thinking so sloppy that it could nourish hogs.
