Effects of Biomanipulation on Nutrient Cycles in Central Florida Lakes via Nutrient Excretion and Bioturbation by Gizzard Shad. May 2004-September 2007

摘要

The purpose of this document is to describe the methodologies used by the St. Johns River Water Management District (SJRWMD) to project and spatially distribute population for water supply planning purposes in support of development of the 2008 District Water Supply Assessment (WSA 2008) and 2010 District Water Supply Plan (DWSP 2010). Because accurately projecting future water demand for public water supply utility service areas requires more precision than is offered by county-level projections available from the Bureau of Economic and Business Research (BEBR) at the University of Florida, the generally accepted standard throughout the State of Florida, SJRWMD contracted with GIS Associates, Inc., to provide small-area population projections for the 18 counties located partly or entirely within SJRWMD. This was achieved by developing a small area population projection and distribution model. The present document describes the Small Area Population Projection and Distribution Model methodology and its use to project and distribute future populations. Ultimately, these small-area population projections were used as a basis for making future water demand projections for SJRWMD.
