Project Summary The Honolulu District, U.S. Army Corps of Engineers (Corps) is evaluating flood risk management problems and opportunities on the Waiakea and Palai Streams near Hilo, Hawaii. The enclosed Integrated Feasibility Report and Environmental Assessment documents the planning process for evaluating potential streambank protection alternatives to demonstrate consistency with Corps planning policy and compliance with the National Environmental Policy Act and the State of Hawaii Chapter 343, Hawai‘i Revised Statutes. The Corps is the lead federal agency conducting this study. The non-Federal sponsor is the County of Hawaii, Department of Public Works. The study area encompasses the Palai and Waiakea Stream watersheds. Waiakea Stream, Palai Stream, and Four Mile Creek are three of the five tributaries within the Wailoa River system, draining about 160 square miles into Hilo Bay. The study will assist in identifying flood risk management measures and will evaluate and compare the benefits, costs, and impacts to the human environment of study alternatives including the No Action Alternative. The purpose of the study is to reduce flood risks to structures, property, and critical infrastructure. The tentatively selected plan includes construction of detention basins, a diversion channel, levees, and floodwalls to reduce flood risk in the study area.

  • The Cavernicolous Fauna of Hawaiian Lava Tubes, 1
    Pacific Insects 15 (1): 139-151 20 May 1973 THE CAVERNICOLOUS FAUNA OF HAWAIIAN LAVA TUBES, 1. INTRODUCTION By Francis G. Howarth2 Abstract: The Hawaiian Islands offer great potential for evolutionary research. The discovery of specialized cavernicoles among the adaptively radiating fauna adds to that potential. About 50 lava tubes and a few other types of caves on 4 islands have been investigated. Tree roots, both living and dead, are the main energy source in the caves. Some organic material percolates into the cave through cracks associated with the roots. Cave slimes and accidentals also supply some nutrients. Lava tubes form almost exclusively in pahoehoe basalt, usually by the crusting over of lava rivers. However, the formation can be quite complex. Young basalt has numerous avenues such as vesicles, fissures, layers, and smaller tubes which allow some intercave and interlava flow dispersal of cavernicoles. In older flows these avenues are plugged by siltation or blocked or cut by erosion. The Hawaiian Islands are a string of oceanic volcanic islands stretching more than 2500 km across the mid-Pacific. The western islands are old eroded mountains which are now raised coral reefs and shoals. The eight main eastern islands total 16,667 km2 and are relatively young in geologic age. Ages range from 5+ million years for the island of Kauai to 1 million years for the largest island, Hawaii (Macdonald & Abbott, 1970). The native fauna and flora are composed of those groups which dis­ persed across upwards of 4000 km of open ocean or island hopped and became successfully established.

  • Raw Sewage and Solid Waste Dumps in Lava Tube Caves of Hawaii Island
    William R. Halliday - Raw sewarge and sold waste dumps in lave tube caves of Hawaii Island. Journal of Cave and Karst Studies, v. 65, n. 1, p. 68-75. RAW SEWAGE AND SOLID WASTE DUMPS IN LAVA TUBE CAVES OF HAWAII ISLAND WILLIAM R. HALLIDAY Hawaii Speleological Survey, 6530 Cornwall Court, Nashville, TN 37205 USA [email protected] Lava tubes on the island of Hawaii (and elsewhere) are possible subsurface point sources of contamina- tion in addition to more readily identifiable sources on the surface. Human and animal waste, and haz- ardous and toxic substances dumped into lava tube caves are subject to rapid transport during flood events, which are the dominant type of groundwater flow through Hawaiian lava tubes. Although these waste materials may not be a major source of pollution when compared with some surface sources, this potential hazard should be evaluated much as in the case of karstic floodwater conduits. This paper explores the interaction of water flow and solid waste dumps and sewage in lava tubes and lava tube caves of Hawaii Island, Hawaii - an island almost as large as the state of Connecticut (Fig. 1)-and resulting potential threats to groundwater quality. In recent years, Hawaiian cavers and speleologists have become increasingly concerned about these occurrences. Some of the solid waste dumps can be seen to contain partially empty containers of toxic and/or hazardous substances (Fig. 2), including automotive and agricultural waste. Stinking raw sewage speaks for itself (Fig. 3), and members of the Hawaii chapter of the National Speleological Society have been shown the top of a septic tank or cesspool near Keaau said to consist of an unlined segment of lava tube cave.

Modern human use of caves is typically for tourism, so understanding surface-underground weather-climate interactions is important when caves carry streams that are prone to flooding in response to surface precipitation. The purpose of this research is to document the effects of surface weather conditions on cave meteorology in three different cave system types located in different geographic locations including an island, the central USA, and at high elevations in British Columbia.

  • Exploration of the Emesine Cave and the 1880-81 Flows of Mauna Loa
    EXPLORATION of EMESINE CAVE and THE 1880-81 FLOWS OF MAUNA LOA VOLCANO by Don Coons Hawai`i Speleological Survey PO Box 7032 Ocean View Hawai`i 96737 [email protected] On May 1, 1880 an eruption of lava began in Moku`aweoweo, the summit crater of Mauna Loa on the Big Island of Hawai`i. The flow of lava is believed to have lasted for only a few days and was not easily visible at most locals on the island. In and of itself, this was not a noteworthy event. Small eruptions of this type are more or less the norm for Mauna Loa. Most residents of the island paid little attention. Volcanologists today realize that these events are important indicators of bigger things to come on Mauna Loa, the Long Mountain. On November 5, 1880 a second eruption began at an elevation of 11,000 feet along the Northeast Rift Zone of the mountain, roughly one mile above Pu`u Ula`ula. The National Park Service maintains a cabin at Red Hill along their summit trail in this area today. This second episode of the eruption sent high fountains of lava into the air as the magma found a path to the surface through narrow cracks and faults along the Rift Zone area. Though still a long ways away, this pyroclastic spectacle was clearly visible from Hilo and most of the eastern half of the island. The high fountains continued for two weeks, pumping out massive amounts of lava and creating flows down each flank of the ridgeline.

The founding populations may have traits that make colonization of underground spaces even more likely. To investigate the process of cave adaptation and the number of times that flightlessness has evolved in a group of reportedly flightless Hawaiian cave moths, we tested the flight ability of 54 Schrankia individuals from seven caves on two islands. Several caves on one island were sampled because separate caves could have been colonized by underground connections after flightlessness had already evolved. A phylogeny based on approximately 1500 bp of mtDNA and nDNA showed that Schrankia howarthi sp. nov. invaded caves on two islands, Maui and Hawaii. Cave-adapted adults are not consistently flightless but instead are polymorphic for flight ability.

  • The Origin of Tubular Lava Stalactites and Other Related Forms 139
    135 Int. J. 5peleol.. 27 B (1/4), (1998): 135-145. THE ORIGIN OF TUBULAR LAVA STALACTITES** AND OTHER RELATED FORMS Kevin Allred' and Carlene Allred' ABSTRACT Tubular lava stalactites are often found in lava tubes. Field observations, sample analysis, and compara- tive studies indicate that these arc segregations extruded during cooling from partially crystallized lava at about 1,070 - 1,000 0c. Retrograde boiling (gas pressure) within the lava provides a mechanism to expel the interstitial liquid. In addition to tubular lava stalactites, a variety of other lava features can also result, such as lava helictites. lava coralloids. barnacle-like stretched lava, runners. runner channels, allli some lava blisters and squeeze-ups. KeYlVords: lava speleothems, soda straws. experimental growth INTRODUCTION The study sites for this paper are four lava tubes totaling approximately 71 km of mapped passages located on Kilauea volcano, Hawaii (Fig. I). Here, as in other well pre- served lava tubes we investigated in Hawaii and the western United States, interior sur- faces are commonly coated with "a thin, smooth, vitreous surface" known as glaze (Lar- son, 1993). This is sometimes underlain by a variable layer of dark-hued rock on either broken or smooth surfaces. Where thick, the dark deposits are usually associated with slender, worm-like lava stalactites (Fig. 2,3), These are called tubular lava stalactites, and can be straight, branching, eccentric, or even deflated. Their interiors are usually an entrainment of elongated vesicles and septa, but some examples are completely solid or hollow (Larson, 1993). Where these stalactites drain, globular stalagmites might be built (Fig.
