a further energy loss due to reflection from the coping wall and overcoming the gutter lip to re-enter the pool.
It has been found that wave gutters are most effective when the uppermost location of the edge of the gutter lip is substantially at the water level of the pool. Wave dissipation efficiency of the gutter lip decreases when water levels are set above or below this edge. Accordingly, many of the larger or olympic-sized pools, built especially for racing, usually combine such wave gutters with extra large pumping apparatus and plumbing arrangements in order to adjust the water level within the gutter rapidly for optimum wave reduction by the gutters. Unfortunately, such wave control is very expensive and, therefore, usually omitted from modern home and club pools inWASHINGTON — As legislators look toward consolidating the hefty annual defense spending bill recently passed in the House with its Senate equivalent, one of the most unexpected debates is over a proposal to create a Space Corps, which already is facing high-level opposition from the Pentagon.

The House approved a plan that would create a Space Corps within the Air Force to oversee military operations in that emerging, and important, domain of military competition, and it would be organized similarly to how the Marine Corps is a distinct service under the Navy. The Space Corps would be the first newly created military branch since the Air Force in 1947.

The House vision for the Space Corps is included in the National Defense Authorization Act, the annual set of policy directions
