This book was released on 1979 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analog model was used to evaluate ground-water conditions on the south coast of Puerto Rico. Water levels during a normal period and during an extended drought were simulated. Recharge and discharge values are reported. The model was also used to evaluate the possibilities of using treated waste water to recharge the aquifer. Three methods were considered: infiltration basins, injection, and irrigation. The tests were planned to determine what changes in water levels would result if certain rates of application were used. Because of the limited vertical hydraulic conductivity, irrigation is suggested as the most practical method of waste-water use. Injection, though practical from the mechanical standpoint, may be ojectionable from health and aesthetic standpoints. (Author).

This book was released on 2014-06-30 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: An evaluation to define groundwater-quality conditions, with emphasis on the distribution of nitrate concentration, to identify potential sources leading to elevated nitrate concentrations and to estimate the nitrate loads from major sources, was conducted by the U.S. Geological Survey in the South Coast aquifer, Santa Isabel area, between January 2008 and May 2009. The study area covers approximately 5,800 hectares of the south coastal plain of Puerto Rico and 470 hectares in the foothills within the municipality of Santa Isabel. Agriculture is the principal land use in the area and includes the cultivation of diverse truck-farm crops, bioengineered crops for seed production, and until 2007, commercial poultry farms. Nitrate concentrations in groundwater near the center of the South Coast aquifer, Santa Isabel area, have increased from a range of 0.9 to 5.9 milligrams per liter as nitrogen in 1967 to a range of 1.3 to 23.6 milligrams per liter as nitrogen in 2008. Analyses for the stable isotope ratios of nitrogen-15/ nitrogen-14 and oxygen-18/oxygen-16 in nitrate were used to infer the source of nitrate in the aquifer and in the foothills north of the coastal plain. Results obtained from the samples analyses of stable isotope ratios indicate that the high nitrate concentrations in the western and central parts of the study area were in the range typically associated with soil nitrogen.

Book excerpt: The limestone region of PR covers about 27% of the island1s surface and has karst features. The karst belt (KB), that part of the northern limestone with the most spectacular karst landforms, covering 65% of the northern limestone, is the focus here. Chapters: geography; features: geomorphological, hydrological, and ecological diversity; nat1l. resources; econ. importance: water, other minerals, ag., forestry, and environ. disturbances; history of intensive use; vulnerable to human activity: cutting vs. paved over forests, draining vs. filling wetlands, conversion vs. trans1n. of land uses, pumping vs. overdrafting aquifers, contaminating vs. poisoning ground water, and surface water pollution; and proposal for transferring KB to the public domain.

This book was released on 2022-04-30 with total page 755 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Intergovernmental Panel on Climate Change (IPCC) is the leading international body for assessing the science related to climate change. It provides policymakers with regular assessments of the scientific basis of human-induced climate change, its impacts and future risks, and options for adaptation and mitigation. This IPCC Special Report on the Ocean and Cryosphere in a Changing Climate is the most comprehensive and up-to-date assessment of the observed and projected changes to the ocean and cryosphere and their associated impacts and risks, with a focus on resilience, risk management response options, and adaptation measures, considering both their potential and limitations. It brings together knowledge on physical and biogeochemical changes, the interplay with ecosystem changes, and the implications for human communities. It serves policymakers, decision makers, stakeholders, and all interested parties with unbiased, up-to-date, policy-relevant information. This title is also available as Open Access on Cambridge Core.
