ABSTRACT: Quarterly monitoring of Upper Newport Bay, a highly eutrophic southern California estuary, has provided conflicting indicators of nutrient limitation for the seasonal macroalgal blooms in this system. Water column N:P ratios were high, up to 370:1, suggesting phosphorous limitation, while sediment N:P ratios were low, «4:1), suggesting nitrogen limitation. A microcosm experiment was conducted to test whether macroalgal biomass was nitrogen or phosphorous limited in this system. -

The downstream of the world’s largest Three Gorges Dam (TGD) along Yangtze River (1560 km) hosts numerous mid-channel bars (MCBs). The morphodynamics of these MCBs are crucial to the river’s hydrological processing, local ecological functioning and socioeconomic development. However, a systematic understanding of such dynamics and their 20 linkages to the TGD across the entire downstream reach remain largely unknown. Using Landsat archive images and a thematic extracting scheme, the work presents comprehensive monitoring of MCB dynamics in terms of number, area, and shape, in the downstream of the TGD during 1985–2018. -
Watershed Summaries
Appendix A: Watershed Summaries Preface California’s watersheds supply water for drinking, recreation, industry, and farming and at the same time provide critical habitat for a wide variety of animal species. Conceptually, a watershed is any sloping surface that sheds water, such as a creek, lake, slough or estuary. In southern California, rapid population growth in watersheds has led to increased conflict between human users of natural resources, dramatic loss of native diversity, and a general decline in the health of ecosystems. California ranks second in the country in the number of listed endangered and threatened aquatic species. This Appendix is a “working” database that can be supplemented in the future. It provides a brief overview of information on the major hydrological units of the South Coast, and draws from the following primary sources: • The California Rivers Assessment (CARA) database (http://www.ice.ucdavis.edu/newcara) provides information on large-scale watershed and river basin statistics; • Information on the creeks and watersheds for the ESU of the endangered southern steelhead trout from the National Marine Fisheries Service (http://swr.ucsd.edu/hcd/SoCalDistrib.htm); • Watershed Plans from the Regional Water Quality Control Boards (RWQCB) that provide summaries of existing hydrological units for each subregion of the south coast (http://www.swrcb.ca.gov/rwqcbs/index.html); • General information on the ecology of the rivers and watersheds of the south coast described in California’s Rivers and Streams: Working -

5.4 Biological Resources
5.4 Biological Resources The biological resources analysis was based on a biological survey and memorandum prepared for the subject site by Phil Brylski, Ph.D on May 9, 2011 and is provided in Appendix C. 5.4.1 ENVIRONMENTAL SETTING Local Setting Relationship to the Orange County NCCP/HCP The Natural Community Conservation Act (the Act), codified in Fish and Game Code Sections 2800-2840 and signed into law on October 1991, authorizes the preparation of Natural Community Conservation Plan/Habitat Conservation Plans (NCCP/HCPs). The Act is a State of California effort to protect critical vegetative communities and their dependent wildlife species. Under this program, the County of Orange, other participating agencies and special districts, and participating landowners, worked with the California Department of Fish and Game (CDFG) and United States Fish and Wildlife Service (USFWS) to prepare a coastal sage scrub NCCP/HCP called the Natural Community Conservation Plan and Habitat Conservation Plan and Habitat Conservation Plan, County of Orange Central and Coastal Subregion. The NCCP/HCP was reviewed and approved by the CDFG and USFWS in 1996. It addressed protection and management of coastal sage scrub habitat and coastal sage scrub-obligate species, and other covered habitats and species, and mitigated anticipated impacts to those habitats and species, on a programmatic, subregional level, rather than on a project-by-project, single species basis. The NCCP/HCP identified development areas where impacts to species and habitats receiving regulatory coverage under the NCCP/HCP would be authorized. The HCCP/HCP was analyzed in a joint EIR/EIS prepared under the auspices of the County of Orange and the USFWS as lead agencies, while the CDFG and the City of San Juan Capistrano were responsible agencies. -

Approved by: May 2016 Ken E Gause, Director International Affairs Group Center for Strategic Studies Copyright © 2016 CNA Abstract The Brahmaputra River originates in China and runs through India and Bangladesh. China and India have fought a war over contested territory through which the river flows, and Bangladesh faces human security pressures in this basin that will be magnified by upstream river practices. Controversial dam-building activities and water diversion plans could threaten regional stability; yet, no bilateral or multilateral water management accord exists in the Brahmaputra basin. This project, sponsored by the MacArthur Foundation, provides greater understanding of the equities and drivers fueling water insecurity in the Brahmaputra River basin. After conducting research in Dhaka, New Delhi, and Beijing, CNA offers recommendations for key stakeholders to consider at the subnational, bilateral, and multilateral levels to increase cooperation in the basin. These findings lay the foundation for policymakers in China, India, and Bangladesh to discuss steps that help manage and resolve Brahmaputra resource competition, thereby strengthening regional security. -

EFFECTS OF HYDROLOGICAL CONNECTIVITY ON THE BENTHOS OF A LARGE RIVER (LOWER MISSISSIPPI RIVER, USA) A Dissertation presented in partial fulfillment of requirements for the degree of Doctor of Philosophy in the Department of Biological Sciences The University of Mississippi by AUDREY B. HARRISON May 2018 Copyright © 2018 by Audrey B. Harrison All rights reserved. ABSTRACT The effects of hydrological connectivity between the Mississippi River main channel and adjacent secondary channel and floodplain habitats on macroinvertebrate community structure, water chemistry, and sediment makeup and chemistry are analyzed. In river-floodplain systems, connectivity between the main channel and the surrounding floodplain is critical in maintaining ecosystem processes. Floodplains comprise a variety of aquatic habitat types, including frequently connected secondary channels and oxbows, as well as rarely connected backwater lakes and pools. Herein, the effects of connectivity on riverine and floodplain biota, as well as the impacts of connectivity on the physiochemical makeup of both the water and sediments in secondary channels are examined. -
On the Formation of Fluvial Islands
AN ABSTRACT OF THE DISSERTATION OF Joshua R. Wyrick for the degree of Doctor of Philosophy in Civil Engineering presented on March 31, 2005. Title: On the Formation of Fluvial Islands Abstract approved: Signature redacted for privacy. Peter C. Klingeman This research analyzes the effects of islands on river process and the effects river processes have on island formation. A fluvial island is defined herein as a land mass within a river channel that is separated from the floodplain by water on all sides, exhibits some stability, and remains exposed during bankfull flow. Fluvial islands are present in nearly all major rivers. They must therefore have some impact on the fluid mechanics of the system, and yet there has never been a detailed study on fluvial islands.Islands represent a more natural state of a river system and have been shown to provide hydrologic variability and biotic diversity for the river. This research describes the formation of fluvial islands, investigates the formation of fluvial islands experimentally, determines the main relations between fluvial islands and river processes, compares and describes relationships between fluvial islands and residual islands found in megaflood outwash plains, and reaches conclusions regarding island shape evolution and flow energy loss optimization. Fluvial islands are known to form by at least nine separate processes: avulsion, gradual degradation of channel branches, lateral shifts in channel position, stabilization of a bar or riffle, isolation of structural features, rapid incision of flood deposits, sediment deposition in the lee of an obstacle, isolation of material deposited by mass movement, and isolation of riparian topography after the installation of a dam. -
