Introduction: Asheville, NC is a City that has re‐invented itself and developed a brand, nationwide, as a destination for active outdoor recreation. Formerly a center of industry and commerce with ties to the Vanderbilts, the City has experienced a renaissance and has become a mountain destination in the heart of the Appalachians. Asheville’s city center is now a tourist destination with walking malls, boutique restaurants and shopping experiences. The City has worked to continue this transformation through development of the Arts District in concert with greenways and parks creation along the French Broad River. The Arts District redevelopment seeks to transform warehouses and historic industrial facilities into a thriving district that will further the City’s reputation as a destination. As a part of this effort, the City has attracted nationally recognized breweries such as the New Belgium Brewery and Sierra Nevada, amongst others, to this area. One of the unique characteristics of the arts district is that it abuts the French Broad River along a reach that is popular for tubing and floating. The community wishes to maximize the potential of this recreational amenity by creating a whitewater park that will attract kayakers and rafters and that can host competitive whitewater events in the heart of Asheville. Whitewater parks are community parks that are centered on the river. The parks include waves, eddies, and other features that are attractive to in‐stream users to pursue recreational kayaking, surfing, and floating. These parks, surrounded by trails and recreational areas, have not only achieved their original objective of attracting paddle sports enthusiasts, but have often exceeded expectations by becoming focal points for their communities and recreational destinations for outdoor tourism. Whitewater parks often play host to major events centered on slalom or freestyle competitions or host river festivals that feature local arts and culture. In addition, Whitewater Parks can have a positive economic impact on the local community, as visitors spend money at local restaurants, lodging, and retail establishments. Some cities, like Golden, Colorado; and Reno, Nevada have reported impacts on the local economy, from tourism generated by the park, on the order of millions of dollars per year. The timing for this project is ideal. The City has recently received significant grant funding for Greenways

  • CHAPTER-6 Cross-Drainage and Drop Structures 6.1 Aqueducts and Canal Inlets and Outlets 6.1.1 Introduction
    Cross-Drainage and Drop Structures CHAPTER-6 Cross-Drainage and Drop Structures 6.1 Aqueducts and canal inlets and outlets 6.1.1 Introduction The alignment of a canal invariably meets a number of natural streams (drains) and other structures such as roads and railways, and may sometimes have to cross valleys. Cross drainage works are the structures which make such crossings possible. They are generally very costly, and should be avoided if possible by changing the canal alignment and/or by diverting the drains. 6.1.2 Aqueducts An aqueduct is a cross-drainage structure constructed where the drainage flood level is below the bed of the canal. Small drains may be taken under the canal and banks by a concrete or masonry barrel (culvert), whereas in the case of stream crossings it may be economical to flume the canal over the stream (e.g. using a concrete trough, Fig. 6.1(a)). When both canal and drain meet more or less at the same level the drain may be passed through an inverted siphon aqueduct (Fig. 6.1(d)) underneath the canal; the flow through the aqueduct here is always under pressure. If the drainage discharge is heavily silt laden a silt ejector should be provided at the upstream end of the siphon aqueduct; a trash rack is also essential if the stream carries floating debris which may otherwise choke the entrance to the aqueduct. 6.1.3 Superpassage In this type of cross-drainage work, the natural drain runs above the canal, the canal under the drain always having a free surface flow.

  • 1 Isaac River Condition, Condition Trajectory and Management
    Memo Subject Response to information request from DEHP From Rohan Lucas Distribution BMA Date 12 February 2016 Project Broadmeadow EA amendment – Watercourse Subsidence 1 Isaac River condition, condition trajectory and management 1.1 Request The administering authority requires more information relating to the proactive management strategies that BMA will adopt to ensure the condition trajectory of the diversion is not negatively impacted by subsidence. 1.2 Response Understanding the incremental risk posed by subsidence The Isaac River diversion, constructed in the mid 1980’s was undertaken to a different standard to that which would be adopted today. The diversion underwent major erosional adjustment in the 1980’s and 1990’s (see Figure 2). Following some management intervention in the mid-late 1990’s (including timber pile fields) and a period without any major flow events from 1991 to 2007 (refer to Figure 1), the diversion underwent substantial recovery. This recovery included the deposition of benches against toe of bank and colonisation of those benches with riparian vegetation, providing a near continuous coverage along the diversion. These vegetated benches protect the near vertical, erodible upper banks from erosion in the majority of flow events (refer Figure 3). The diversion, which reduced river length by several kilometres, was constructed with two drop structures to compensate for the increase in gradient. One of these structures is now largely redundant and the other has been subject to damage from flow events and repair on numerous occasions. The remaining functional structure performs its design intent during smaller flows but is ineffective in larger flows in reducing energy conditions sufficiently.

  • Drop Structures
    DROP STRUCTURES 1 DESCRIPTION OF TECHNIQUE Drop structures (also known as grade controls, sills, or weirs) are low-elevation structures that span the entire width of the channel, creating an abrupt drop in channel bed and water surface elevation in a downstream direction. Drop structures have been used extensively in Washington State to stabilize channel grades, improve fish passage, and to reduce erosion. Generally speaking, in fish bearing waters, vertical drops must not exceed 1 foot [WAC 220-110-070]; lesser drops are often required to accommodate certain species and age classes of fish. Drop Structures are designed to spill and direct flow such that there is a distinct drop in water surface elevation at normal low flows. The purpose of drop structures may include but is not limited to: • redistribute or dissipate energy; • stabilize the channel bed; • restore a step pool morphology to an altered channel • limit channel incision; • limit bank erosion by directing flow away from an eroding bank; • modify the channel bed profile and form by promoting collection, sorting and deposition of sediment; • create structural and hydraulic diversity in uniform channels; • improve fish passage over natural and artificial barriers by backwatering the upstream reach; • scour the channel bed, creating holding pools for fish and other aquatic life; • provide backwater (depth) in groundwater fed side channels; or • raise the bed of an incised stream to reconnect it with its floodplain. Drop structures may resemble porous weirs in appearance. But while drop structures direct water over the structure and are applied primarily to modify the profile of a channel, porous weirs allow water to flow through the structure and are applied primarily to redirect or concentrate flow.

  • Whitewater Park Toolkit
    WHITEWATER PARK TOOLKIT A Paddler’s Guide to Championing a Local Project Every Project Needs a Local Champion Nationally, there are more than 1,000 rivers suitable for whitewater paddling, most of which are located off the beaten path and away from municipalities. Countless more, however, flow right through the heart of communities large and small. While many of these are not currently prone to paddling, with a little help they can be converted into destination whitewater play parks, becoming gathering places for their communities, enhancing the riparian zones, and even generating revenues for their towns. But it takes a champion and a little elbow grease. Most of today’s in-stream whitewater parks were the result of a paddler or group of paddlers that had a vision for a local park and the passion to get the ball rolling. Championing the development of a whitewater park for your community is not a simple process, nor is it the same from one community to the next. It takes tenacity, flexibility, and patience. Yet, armed with the right information and inspiration, you can be the spark that leads to a successful whitewater park in your community. The purpose of this Whitewater Park Toolkit is to serve as a guide for whitewater enthusiasts, anglers, and other community stakeholders to advocate for the development of a local in-stream whitewater park in their community. It provides a general understanding of the process, player, and costs involved in building a fun, safe, and environmentally S2O Design Whitewater Park Toolkit 01 CONTENTS 03

E-mail: [email protected] ABSTRACT: Engineered flood bypasses, or simplified conveyance floodplains, are natural laboratories in which to observe floodplain development and therefore present an opportunity to assess delivery to and sedimentation within a specific class of floodplain. The effects of floods in the Sacramento River basin were investigated by analyzing hydrograph characteristics, estimating event-based sediment discharges and reach erosion/deposition through its bypass system and observing sedimentation patterns with field data. Sediment routing for a large, iconic flood suggests high rates of sedimentation in major bypasses, which is corroborated by data for one bypass area from sedimentation pads, floodplain cores and sediment removal reporting from a government agency.

  • Design Guidelines and Details
    CHAPTER IV DESIGN GUIDELINES AND DETAILS A. General In this chapter, general design guidelines are provided for various bank stabilization methodologies introduced in Chapter II. Selection criteria for any of these erosion control methods is outlined in Chapter III. Details for the stabilization and erosion control methods discussed in this chapter are found in Appendix A. WEST PITTMAN CREEK DOWNSTREAM OF DIAMONDHEAD DRIVE, PLANO, TEXAS B. Structural and Armor Methods 1. Concrete-Lined Channel. Concrete-lined channels are a common drainage feature of small, urban streams in North Central Texas, especially in areas where right-of-way for drainage purposes is minimal. In addition to flood flow capacity, concrete lined channels should be designed to maintain scour velocities (>2 fps) throughout the expected flow regime. Supercritical flow will not be allowed. Minimum bottom width shall be 10 feet. Channel intersections shall be at an angle not exceeding IV-1 15 degrees. The minimum radius of centerline curvature shall be three times the top width of the channel unless superelevation computations are submitted for review. Subsurface drainage should be provided to prevent scour under the slabs and relieve pressures behind protected slopes. Uplift forces on the slabs should be evaluated. Joint location and frequency should be carefully considered by the design engineer (USACE, 1991). A typical concrete lined channel section is shown in Plate 1 of Appendix A. The designer is also referred to the standard details of the community in which they are working. 2. Rock Riprap Revetment. Rock or stone can be an effective erosion control measure if properly designed.
