Hydrology of the Hawaiian Islands


Book Description

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.

Hydrology


Book Description

Hydrology covers the fundamentals of hydrology and hydrogeology, taking an environmental slant dictated by the emphasis in recent times for the remediation of contaminated aquifers and surface-water bodies as well as a demand for new designs that impose the least negative impact on the natural environment. Major topics covered include hydrological principles, groundwater flow, groundwater contamination and clean-up, groundwater applications to civil engineering, well hydraulics, and surface water. Additional topics addressed include flood analysis, flood control, and both ground-water and surface-water applications to civil engineering design.













Kua‘āina Kahiko


Book Description

In early Hawai‘i, kua‘āina were the hinterlands inhabited by nā kua‘āina, or country folk. Often these were dry, less desirable areas where much skill and hard work were required to wrest a living from the lava landscapes. The ancient district of Kahikinui in southeast Maui is such a kua‘āina and remains one of the largest tracts of undeveloped land in the islands. Named after Tahiti Nui in the Polynesian homeland, its thousands of pristine acres house a treasure trove of archaeological ruins—witnesses to the generations of Hawaiians who made this land their home before it was abandoned in the late nineteenth century. Kua‘āina Kahiko follows kama‘āina archaeologist Patrick Vinton Kirch on a seventeen-year-long research odyssey to rediscover the ancient patterns of life and land in Kahikinui. Through painstaking archaeological survey and detailed excavations, Kirch and his students uncovered thousands of previously undocumented ruins of houses, trails, agricultural fields, shrines, and temples. Kirch describes how, beginning in the early fifteenth century, Native Hawaiians began to permanently inhabit the rocky lands along the vast southern slope of Haleakalā. Eventually these planters transformed Kahikinui into what has been called the greatest continuous zone of dryland planting in the Hawaiian Islands. He relates other fascinating aspects of life in ancient Kahikinui, such as the capture and use of winter rains to create small wet-farming zones, and decodes the complex system of heiau, showing how the orientations of different temple sites provide clues to the gods to whom they were dedicated. Kirch examines the sweeping changes that transformed Kahikinui after European contact, including how some maka'āinana families fell victim to unscrupulous land agents. But also woven throughout the book is the saga of Ka ‘Ohana o Kahikinui, a grass-roots group of Native Hawaiians who successfully struggled to regain access to these Hawaiian lands. Rich with ancedotes of Kirch’s personal experiences over years of field research, Kua'āina Kahiko takes the reader into the little-known world of the ancient kua‘āina.
