Introduction Planning Implications
DRAFT 4 City of Goleta, California May 2004 BACKGROUND REPORT NO. 24 Hydrology and Water Quality INTRODUCTION This background report describes the hydrological characteristics of the City of Goleta. The City of Goleta’s hydrological features consist of creeks and associated flood plains, ponds, wetlands, and the Ocean. While this report provides an overview of these resources, other reports examine particular areas or issues in the City in greater depth. These reports include Ellwood Mesa Open Space Plan and the related Environmental Impact Report; Comstock Homes Development and Ellwood Mesa Open Space Plan, March 2004, Goleta Slough Ecosystem Management Plan, December 1997, and Water Quality Analysis Report, County of Santa Barbara, December 2003. PLANNING IMPLICATIONS Since hydrological features shape the land forms of an area, these features contribute to the physical character of the community. Hydrological forces create these land forms through processes such as erosion and flooding. These processes in turn pose constraints and hazards for use and development. Water, as the basis for all life, creates the environment for the community’s biological resources and ecology. Modification of the hydrological system, either by physical alteration or by change in water quality, will affect these biological systems. The potential of adverse impacts associated with development is an important constraint on how land might be used, developed or managed. Water and its quality affects other aspects of the quality of life since water is the basis of many recreational activities. City of Goleta, California XXIV-1 General Plan Report: Hydrology GENERAL TOPOGRAPHY AND DRAINAGE The City of Goleta is situated in the western portion of the Goleta Valley. -
The Use of Subsidence to Estimate Carbon Loss from Deforested and Drained Tropical Peatlands in Indonesia
Review The Use of Subsidence to Estimate Carbon Loss from Deforested and Drained Tropical Peatlands in Indonesia Gusti Z. Anshari 1,2 , Evi Gusmayanti 1,3 and Nisa Novita 4,* 1 Magister of Environmental Science, Universitas Tanjungpura, Pontianak 78124, Indonesia; [email protected] (G.Z.A.); [email protected] (E.G.) 2 Soil Science Department, Universitas Tanjungpura, Pontianak 78124, Indonesia 3 Agrotechnology Department, Universitas Tanjungpura, Pontianak 78124, Indonesia 4 Yayasan Konservasi Alam Nusantara, DKI Jakarta 12160, Indonesia * Correspondence: [email protected] Abstract: Drainage is a major means of the conversion of tropical peat forests into agriculture. Accordingly, drained peat becomes a large source of carbon. However, the amount of carbon (C) loss from drained peats is not simply measured. The current C loss estimate is usually based on a single proxy of the groundwater table, spatially and temporarily dynamic. The relation between groundwater table and C emission is commonly not linear because of the complex natures of heterotrophic carbon emission. Peatland drainage or lowering groundwater table provides plenty of oxygen into the upper layer of peat above the water table, where microbial activity becomes active. Consequently, lowering the water table escalates subsidence that causes physical changes of organic matter (OM) and carbon emission due to microbial oxidation. This paper reviews peat bulk density (BD), total organic carbon (TOC) content, and subsidence rate of tropical peat forest and drained peat. Data of BD, TOC, and subsidence were derived from published and unpublished sources. We Citation: Anshari, G.Z.; Gusmayanti, found that BD is generally higher in the top surface layer in drained peat than in the undrained peat. -

Gross, Ken Johnson, Quinn Labadie, Jessie R. Lacy, Erika McPhee Shaw, Kerstin Wasson, and Andrea Woolfolk Management of Tidal Scour and Wetland Conversion in Elkhorn Slough Hydrology, Habitats and Water Quality: Effects of Five Alternatives Overview Project scope Elkhorn Slough, one of the largest coastal estuaries in California and host to over 750 species of plants and animals, is undergoing rapid ecologic change: in 60 years the channel has deepened by 500 percent and hundreds of acres of salt marsh have died back or are deteriorating. The Elkhorn Slough Tidal Wetland Project, a collaborative effort of about 100 scientists, managers and key stakeholders, was established in 2004 to advance the understanding of the processes and potential solutions to these rapid habitat changes. Ecosystem services provided by the slough and its watershed are threatened by water quality impairment, invasive species, watershed development, freshwater diversion and other stressors, which are the subject of coordinated parallel efforts to steward the resource. The Tidal Wetland Project is a planning process focused on the tidal portion of the ecosystem. Through consensus, this process established goals of preserving and restoring priority habitats including salt marsh, tidal creeks, tidal brackish marshes and soft sediment habitats. -

Characterization of Woody Wetland Vegetation Communities Along Gum Slough
VEGETATION APPENDIX Characterization of Woody Wetland Vegetation Communities along Gum Slough Submitted to: Southwest Florida Water Management District Submitted by: 4030 Boy Scout Boulevard Tampa, Florida 33607 August 2010 Executive Summary The purpose of this study was to characterize relationships among vegetation, soils, and elevations in wetlands along Gum Slough, in Sumter County, Florida, and assist the Southwest Florida Water Management District (District) in establishing minimum flows and levels (MFLs) for the river. Vegetation classes, plant species importance, soil characteristics, and elevations were characterized along 8 transects within the upper reaches of Gum Slough. The study corridor extended 1.6 miles downstream from Transect PHABSIM1 and the slough flows 3.5 miles farther downstream to its confluence with the Withlacoochee River. Vegetation. The permanent ground water flows and clear water of the spring-fed Gum Slough differentiate it from streams and rivers dominated by surface water flows. Unlike many coastal springs rivers, such as the Homosassa and Crystal rivers, Gum Slough has a well-developed floodplain characterized by extensive seasonally and sometimes semipermanently inundated swamps. The floodplain vegetation associated with Gum Slough is similar to vegetation described for parts of the Withlacoochee River floodplain (SWFWMD 1997). Differences in vegetation classes along Gum Slough study corridor were measured using importance values (IVs) that were calculated using tree species density and basal area and subsequently provided a relative measure of species dominance (no units). Differences in species and species importance were significant between the 6 vegetation classes identified along Gum Slough (Wilcoxon Signed Rank test, p < 0.01). Six vegetation classes were characterized as wetland classes and a single upland class was identified.
