9. COASTAL ENGINEERING AND ECOLOGICAL STUDIES PROGRAM 
The persistent natural and man-induced coastal process, considered in light of requirements of a 
growing population for living and recreational areas along the coasts, dictates that coastal zones be well 
understood and carefully managed. Requirements for increased use of coastal lanes for transportation, 
mining, fishing, and waste disposal complicate this multiple-use situation. 
Systems solutions must be sought. Particularly, the national program to develop valuable waterfront 
must concern itself with the possible disastrous effects of coastal development on the ecology of 
marshes, rivers, estuaries, and the near ocean. This area includes the spawning grounds of the majority 
of the ocean’s living resource. Its natural balances are fragile and can be disastrously disarranged by 
seemingly minute adjustments of marine ecology. Changes in water quality can make waters aesthetically 
undesirable and unsafe for recreation. 
The Coastal Engineering and Ecological Studies Program stands as a major requirement for maximizing 
the benefits and utilization of coastal areas.
