    Riparian Buffer A Technical Primer on Assessing Potential Water Quality Improvements for the Quantifying Benefits of Miyun Reservoir in Beijing, China Watershed Interventions September 2016 Prepared by: “Andrew” Feng Fang, Ph.D. Work supported by: Mark S. Kieser 536 E. Michigan Ave, Suite 300 Kalamazoo, MI 49007 USA The China Mega-City Water Fund (CMWF) was launched in August of 2015 in cooperation with the Beijing Forestry Society (BFS), China Biodiversity Conservation and Green Development Foundation (CBCGDF), International Union for Conservation of Nature (IUCN), and Forest Trends. Once fully operating, the CMWF will identify, fund, and help implement watershed improvement projects (“interventions”) to benefit water quality and water quantity in the Miyun Reservoir. The City of Beijing relies in part on this reservoir as a critical drinking water supply. A notable challenge facing the CMWF, and other water funds throughout the world, is the ability to reasonably estimate water quality and/or water quantity benefits associated with specific interventions. Recent 2016 efforts have established an operating framework for the CMWF that will evaluate various watershed interventions in the context of relatively simple, established performance metrics for water quality and water quantity benefits. Coupled with projected costs for such interventions, the CMWF will be able to assess, compare and optimize benefits associated with its investments in watershed improvements with this framework. This Technical Primer1 represents an initial examination of quantification methods that the CMWF and others may use to reliably estimate water resource benefits derived from particular land management interventions in the watershed of the Miyun Reservoir. This approach relies upon existing studies from both the Miyun Reservoir watershed and other basins in China.

  • James City County Perennial Stream Protocol Guidance Manual
    James City County Perennial Stream Protocol Guidance Manual Purpose This protocol defines the procedure for making field determinations of the presence and the origin of a perennial stream. The procedure was developed to meet the requirement of James City County’s Chesapeake Bay Preservation Ordinance, Section 23-8, to perform site-specific field evaluations to determine the boundaries of Resource Protection Areas (RPA) and Section 23-10(2) to identify water bodies with perennial flow. Development of the protocol was finalized using funds from the Chesapeake Bay Implementation Grant #BAY-2007-14-PT awarded to the County by the Department of Conservation and Recreation (DCR). Introduction This protocol describes the process of determining whether a stream in James City County has perennial flow, and if necessary, determining the origin of the perennial stream. The origin of the perennial reach may occur as a transition from an ephemeral or intermittent reach or may occur at a spring with no upslope stream channel. The field identification of a perennial stream is based on the combination of hydrological, physical and biological characteristics of a stream. In the protocol, the field indicators of these characteristics are classified as primary or secondary and ranked using a weighted, four-tiered scoring system similar to the current system developed by the North Carolina Division of Water Quality (NCDWQ 2005) as modified to address conditions in James City County. A stream reach is classified as perennial based on the overall score but with consideration of other supporting information such as long term monitoring or historic information in certain situations.

  • Creek, Stream, Or Branch
    Creek, Stream, or Branch What is the difference between a creek, stream or a branch, and when does a spring become one of them? Let me introduce you to the world of stream classification. To begin at the beginning, streams have their origin high up in their watershed. A watershed is that area in which precipitation falls and collects into water bodies. On a large scale, Mitchell, Yancey, and Avery Counties drain into the French Broad River Basin. Within these river basins are many sub-basins or smaller watersheds that drain into tributaries or creeks. When rainfall hits the earth it either infiltrates and recharges groundwater or it runs off and goes into a stream. Most infiltrating rainfall enters shallow groundwater which feeds year-round streams, which is why year-round, or perennial streams and rivers run with water even in dry weather. Old hand dug or bored (shallow) wells tap into shallow ground water, which is why shallow wells can dry- up during prolonged droughts. Of the approximately 40-55 inches of annual rainfall that Mitchell, Yancey, and Avery Counties receive in an average year, only one inch penetrates into the deep groundwater on which most drilled wells depend. If a stream runs wet only during rainfall events, it is called an ephemeral stream. Ephemeral steams depend upon stormwater runoff for water. These streams are perched above the shallow water table, so when rain stops falling, they dry up. The second level of stream is called an intermittent stream. Intermittent streams run with water only during part of the year, typically during winter and spring when shallow water tables are highest.

  • A Hydrological Framework for Persistent River Pools in Semi- Arid Environments

A hydrological framework for persistent river pools in semi- arid environments 1 Sarah A. Bourke , Margaret Shanafield2, Paul Hedley3, Shawan Dogramaci3 5 1School of Earth Sciences, University of Western Australia, Crawley WA 6009 Australia 2College of Science and Engineering, Flinders University, Bedford Park, SA 5042, Australia 3Rio Tinto Iron Ore, Perth, WA 6000 Australia Correspondence to: Sarah A. Bourke ([email protected]) Abstract 10 Persistent surface water pools along non-perennial rivers represent an important water resource for the plants, animals, and humans that inhabit semi-arid regions. While ecological studies of these features are not uncommon, these are rarely accompanied by a rigorous examination of the hydrological and hydrogeological characteristics that create or support the pools. Here we present an overarching framework for understanding the hydrology of persistent pools based on data from 22 pools in the Hamersley Basin in Western Australia. Three dominant 15 mechanisms that control the occurrence of persistent pools have been identified; perched pools, through flow pools and groundwater discharge pools. Groundwater discharge pools are further categorized into those that are present because of a geological contact or barrier, and those that are controlled by topography. A suite of diagnostic tools (including geological mapping, hydraulic data and hydrochemical surveys) is generally required to identify the mechanism supporting persistent pools. Perched pools are sensitive to climate variability but their 20 persistence is largely independent of groundwater withdrawals. Water fluxes to pools from alluvial and bedrock aquifers can vary seasonally and resolving these inputs is generally non-trivial.

  • Perennial Stream Field Identification Protocol May 2003
    Perennial Stream Field Identification Protocol May 2003 This protocol defines procedures for making field determinations between perennial and intermittent streams. The protocol was developed to support fieldwork for the Fairfax County stream-mapping project. Several existing protocols were used to develop this protocol including: • Virginia Chesapeake Bay Local Assistant Department’s (CBLAD) “Very Rough Draft Guidance for Making Perennial vs. Intermittent Stream Determinations.” December 2000. • North Carolina Division of Water Quality’s “Perennial Stream Reconnaissance Protocols” January 2000. Version 2.0. (http://h2o.enr.state.nc.us/ncwetlands/strmfrm.html) • Williamsburg Environmental Group, Inc. “Qualitative Field Procedures for Perennial Stream Determinations.” [unpublished manuscript] Corresponding Author: D.A. DeBerry. • U.S. Corps of Engineers Branch Guidance Letter No 95-01: Identification of Intermittent versus Ephemeral Streams – Not Ditches. October 1994. The determination between a perennial and intermittent stream is based on the combination of hydrological, physical and biological characteristics of the stream. Field indicators of these characteristics are classed as primary or secondary and ranked using a weighted, four-tiered scoring system similar to the current system developed by the North Carolina Division of Water Quality (NCDWQ). As discussed below, a stream reach is classified as perennial based on the overall score as well as supporting information such as long term flow monitoring, presence of certain aquatic organisms, or historic information. DEFINITIONS Perennial Stream – A body of water flowing in a natural or man-made channel year-round, except during periods of drought. The term “water body with perennial flow” includes perennial streams, estuaries, and tidal embayments. Lakes and ponds that form the source of a perennial stream, or through which the perennial stream flows, are a part of the perennial stream.
