Effects of Riverine Inputs on Coastal Ecosystems and Fisheries ResourcesFood and Agriculture Organization of the United Nations, 1995 - 133 strani Five chapters are presented which address a number of aspects of riverine and runoff effects on coastal marine systems. Examples are presented and documented in which the apparent effects of runnoff-related nutrient enrichment and consequent eutrophication have been important. Various other aspects, such as sedimentation, etc. are explored. The purpose is to advance the scientific, policy, and political dialogue on issues related to utilization and protection of coastal marine ecosystems. The "Marine Catchment Basin" or "MCB" appears to be the logical scale of policy and management interest wherever terrestrial runoff has substantial impacts on a marine system. The MCB expands the "marine ecosystem" concept to include not only the marine aquatic system, but also the adjacent land areas that drain into it. The MCB concept has been identified primarily with semi-enclosed seas, where effects have been particularly dramatic and where the "catchment basin" retains an easily visualized geological context. However, even along open ocean coasts, hydrodynamic processes act to retain coherent masses of water, together with their contained organisms and materials, against the coast. Thus open coastal areas may exhibit MCB features similar to those of enclosed or semi-enclosed basins |
