| high tide line | The line of intersection of the land with the water's surface at the maximum height reached by a rising tide. The high tide line may be determined, in the absence of actual data, by a line of oil or scum along shore objects, a more or less continuous deposit of fine shell or debris on the foreshore or berm, other physical markings or characteristics, vegetation lines, tidal gages, or other suitable means that delineate the general height reached by a rising tide. The line encompasses spring high tides and other high tides that occur with periodic frequency but does not include storm surges in which there is a departure from the normal or predicted reach of the tide due to the piling up of water against a coast by strong winds such as those accompanying a hurricane or other intense storm.

| high-energy shock waves | Compression waves of large amplitude, across which density, pressure, and particle velocity change drastically. (12 Dec 1998) |
| high-fat diet | A diet containing large amounts of fat. (05 Mar 2000) |
| high-fibre diet | A diet high in the nondigestible part of plants, which is fibre. Fibre is found in fruits, vegetables, whole grains, and legumes. Insoluble fibre increases stool bulk, decreases transit time of food in the bowel, and decreases constipation and the risk of colon cancer. Soluble fibre delays absorption of glucose, which helps to control blood sugar in diabetes mellitus, and delays absorption of lipids, which helps to control hyperlipidemia. Recommended in treatment of diverticular disease of the colon. (05 Mar 2000) |
