Book Synopsis Hydrology of the Hawaiian Islands by : L. Stephen Lau
Download or read book Hydrology of the Hawaiian Islands written by L. Stephen Lau and published by University of Hawaii Press. This book was released on 2006-09-30 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: Why is groundwater the predominant drinking water source in Hawaii? Why are groundwater sources susceptible to pesticide contamination? How long does it take for water in the mountains to journey by land and underground passages to reach the coast? Answers to questions such as these are essential to understanding the principles of hydrology—the science of the movement, distribution, and quality of water—in Hawaii. Due to the humid tropical climate, surrounding ocean, volcanic earth, and high mountains, many hydrologic processes in the Islands are profoundly different from those of large continents and other climatic zones. Management of water, land, and environment must be informed by appropriate analyses, or communities and ecosystems face great uncertainty and may be at risk. The protection of groundwater, coastal waters, and streams from pollution and the management of flood hazards are also significant. This volume presents applications of hydrology to these critical issues. The authors begin by outlining fundamental hydrologic theories and the current general knowledge then expand into a formal discussion specific to Hawaii and the distinctive elements and their interrelations under natural and human-influenced conditions. They include chapters on rainfall and climate, evaporation, groundwater, and surface runoff. Details on the quantification of hydrologic processes are available to those with more technical knowledge, but general readers with an interest in the topic—one of singular importance for the Hawaiian Islands—will find much in the volume that is timely and accessible.

Book Synopsis Coastal Groundwater System Changes in Response to Large-scale Land Reclamation by : Haipeng Guo
Download or read book Coastal Groundwater System Changes in Response to Large-scale Land Reclamation written by Haipeng Guo and published by . This book was released on 2009 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most large urban centres lie in coastal regions, which are home to about 25% of the world's population. The current coastal urban population of 200 million is projected to almost double in the next 20 to 30 years. This expanding human presence has dramatically changed the coastal natural environment. To meet the growing demand for more housing and other land uses, land has been reclaimed from the sea in coastal areas in many countries, including China, Britain, Korea, Japan, Malaysia, Saudi Arabia, Italy, the Netherlands, and the United States. Coastal areas are often the ultimate discharge zones of regional ground water flow systems. The direct impact of land reclamation on coastal engineering, environment and marine ecology is well recognised and widely studied. However, it has not been well recognised that reclamation may change the regional groundwater regime, including groundwater level, interface between seawater and fresh groundwater, and submarine groundwater discharge to the coast. This book first reviews the state of the art of the recent studies on the impact of coastal land reclamation on ground water level and the seawater interface. Steady-state analytical solutions based on Dupuit and Ghyben-Herzberg assumptions have been derived to describe the modification of water level and movement of the interface between fresh groundwater and saltwater in coastal hillside or island situations. These solutions show that land reclamation increases water level in the original aquifer and pushes the saltwater interface to move towards the sea. In the island situation, the water divide moves towards the reclaimed side, and ground water discharge to the sea on both sides of the island increases. After reclamation, the water resource is increased because both recharge and the size of aquifer are increased. This book then derives new analytical solutions to estimate groundwater travel time before and after reclamation. Hypothetical examples are used to examine the changes of groundwater travel time in response to land reclamation. After reclamation, groundwater flow in the original aquifer tends to be slower and the travel time of the groundwater from any position in the original aquifer to the sea becomes longer for the situation of coastal hillside. For the situation of an island, the water will flow faster on the unreclaimed side, but more slowly on the reclaimed side. The impact of reclamation on groundwater travel time on the reclaimed side is much more significant than that on the unreclaimed side. The degree of the modifications of the groundwater travel time mainly depends on the scale of land reclamation and the hydraulic conductivity of the fill materials.
