Detailed records need to be kept of the quantities and intervals of the dredging, allowing future projections to be identified.īefore the project commences, hydrographic surveys should be used to determine the existing depths as well as the depths that will be attained after the dredging operation. The biggest problem is usually the disposal of the dredged material, which means that long-term projections are essential. When dredging projects are planned, the locations and quantities of material are the most important considerations that need to be addressed. Evaluating the dredge plant requirements.Considering the applicable environmental, social, and institutional factors that need to be addressed.Identifying potential alternatives for the disposal.Determining the chemical and physical characteristics of the sediments.Assessing the location as well as the amount that needs to be dredged, based on future needs on the site.Preliminary data collection for a dredging and dredged material disposal project should include: On the other hand, long-term goals are focused on the operation and management of the disposal areas. Ideally, the dredging process should be done using the best technical options that are both economically feasible and environmentally compatible. Typically, short-term focus is on the channels that are needed for existing navigation, but it doesn’t necessarily need to be based on the project dimensions. The operation for dredging and dredged material disposal needs to cover both short-term and long-term management goals. This guide is designed to provide an overview of the information that should be considered for these decisions. When new work and maintenance projects require dredging and materials disposal, then specific guidance should be followed for the evaluation of equipment and disposal. Dredging spoil is deposited in a transport barge as a pontoon crane dredges a canal.

The area that is now The Woodlands was used by the Akokisa and Bidai peoples, who relied on the fresh water of Spring Creek. The community won a Special Award for Excellence in 1994 from the Urban Land Institute. Though it began as an exurban development and a bedroom community, it has also attracted corporations and has several corporate campuses, most notably Occidental Petroleum Corporation, Chevron Phillips Chemical, Huntsman Corporation, Woodforest National Bank, Baker Hughes, McKesson Specialty Health, and Halliburton. The Woodlands is located 28 miles (45 km) north of Houston along Interstate 45. The United States Census Bureau defines an urban area separate from the Houston urban area with The Woodlands as a principal city: The Woodlands– Conroe, TX urban area had a 2020 population of 402,454, making it the 103rd largest in the United States. In 2021, The Howard Hughes Corporation estimated the population of The Woodlands was 119,000. Census, the township had a population of 114,436 people. The Woodlands is governed by The Woodlands Township, an organization that provides municipal services and is administered by an elected board of directors. The Woodlands is primarily located in Montgomery County, with portions extending into Harris County. state of Texas in the Houston–The Woodlands–Sugar Land metropolitan statistical area. The Woodlands is a special-purpose district and census-designated place (CDP) in the U.S. The steps below will detail the minor triad chord quality in the key of E. Without this 3rd note, suspended chords tend to have an open and ambiguous sound. Musically, this is interesting, since it is usually the 3rd note of the scale that defines the overall character of the chord as being major (typically described as 'happy') or minor ('sad'). removed completely, and replaced by either the 2nd note of the major scale - a suspended 2nd, or more commonly by the 4th note of the major scale - a suspended 4th. Unlike all of the above qualities, Suspended triad chords do not use the 3rd note of the major scale (at all) to build the chord. Suspended triad chords - using the 2nd or 4th scale notesĪ suspended chord is known in music theory as an altered chord because it takes one of the above chord qualities and modifies it in some way. It is these variations of the 3rd and 5th notes that give each one a distinctive sound for any given key (eg. Triad chord qualities using the 1st, 3rd and 5th scale notesĪll of these triad qualities are based on the 1st, 3rd and 5th notes of the major scale piano diagram above.ĭepending on the chord quality, the 3rd and 5th scale note names of the major scale above might need to be adjusted up or down by one half-note / semitone / piano key. Triad chords exist in four different chord qualities, which are major, minor, augmented, and diminished.Įach chord quality name is the name of the entire chord as a whole, not its individual notes (which will be covered later). The music theory term triad chord means that 3 or more notes played together, or overlapping. This step defines a triad chord, names the triad chord qualities and identifies the notes that vary between them. |
