Applied River Morphology Book' title='Applied River Morphology Book' />In some cases a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as stream, creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features,1 although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location examples are run in some parts of the United States, burn in Scotland and northeast England, and beck in northern England. Sometimes a river is defined as being larger than a creek,2 but not always the language is vague. Rivers are part of the hydrological cycle. Water generally collects in a river from precipitation through a drainage basin from surface runoff and other sources such as groundwater recharge, springs, and the release of stored water in natural ice and snowpacks e.

Topography. A river begins at a source or more often several sources, follows a path called a course, and ends at a mouth or mouths. The water in a river is usually confined to a channel, made up of a stream bed between banks. In larger rivers there is often also a wider floodplain shaped by flood waters over topping the channel. Floodplains may be very wide in relation to the size of the river channel. This distinction between river channel and floodplain can be blurred, especially in urban areas where the floodplain of a river channel can become greatly developed by housing and industry. Rivers can flow down mountains, through valleys depressions or along plains, and can create canyons or gorges. The term upriver or upstream refers to the direction towards the source of the river, i. Likewise, the term downriver or downstream describes the direction towards the mouth of the river, in which the current flows. Applied River Morphology Rosgen' title='Applied River Morphology Rosgen' />The term left bank refers to the left bank in the direction of flow, right bank to the right. The river channel typically contains a single stream of water, but some rivers flow as several interconnecting streams of water, producing a braided river. Extensive braided rivers are now found in only a few regions worldwide,citation needed such as the South Island of New Zealand. They also occur on peneplains and some of the larger river deltas.

They have multiple sinuous channels carrying large volumes of sediment. There are rare cases of river bifurcation in which a river divides and the resultant flows ending in different seas. An example is the bifurcation of Nerodime River in Kosovo. A river flowing in its channel is a source of energy which acts on the river channel to change its shape and form. In 1. 75. 7, the German hydrologist Albert Brahms empirically observed that the submerged weight of objects that may be carried away by a river is proportional to the sixth power of the river flow speed. This formulation is also sometimes called Airys law. Thus, if the speed of flow is doubled, the flow would dislodge objects with 6. In mountainous torrential zones this can be seen as erosion channels through hard rocks and the creation of sands and gravels from the destruction of larger rocks. A river valley that was created from a U shaped glaciated valley, can often easily be identified by the V shaped channel that it has carved. In the middle reaches where a river flows over flatter land, meanders may form through erosion of the river banks and deposition on the inside of bends. Sometimes the river will cut off a loop, shortening the channel and forming an oxbow lake or billabong. Rivers that carry large amounts of sediment may develop conspicuous deltas at their mouths. Rivers whose mouths are in saline tidal waters may form estuaries. Throughout the course of the river, the total volume of water transported downstream will often be a combination of the free water flow together with a substantial volume flowing through sub surface rocks and gravels that underlie the river and its floodplain called the hyporheic zone. For many rivers in large valleys, this unseen component of flow may greatly exceed the visible flow. Subsurface streams. Most but not all rivers flow on the surface. Subterranean rivers flow underground in caves or caverns. Such rivers are frequently found in regions with limestonegeologic formations. Subglacial streams are the braided rivers that flow at the beds of glaciers and ice sheets, permitting meltwater to be discharged at the front of the glacier. Because of the gradient in pressure due to the overlying weight of the glacier, such streams can even flow uphill. Permanence of flow. An intermittent river or ephemeral river only flows occasionally and can be dry for several years at a time. These rivers are found in regions with limited or highly variable rainfall, or can occur because of geologic conditions such as a highly permeable river bed. Some ephemeral rivers flow during the summer months but not in the winter. Such rivers are typically fed from chalk aquifers which recharge from winter rainfall. In England these rivers are called bournes and give their name to places such as Bournemouth and Eastbourne. Even in humid regions, the location where flow begins in the smallest tributary streams generally moves upstream in response to precipitation and downstream in its absence or when active summer vegetation diverts water for evapotranspiration. Normally dry rivers in arid zones are often identified as arroyos or other regional names. The meltwater from large hailstorms can create a slurry of water, hail and sand or soil, forming temporary rivers. Classification. Nile River delta, as seen from Earth orbit.

Rivers have been classified by many criteria including their topography, their biotic status, and their relevance to white water rafting or canoeing activities. Topographical classification. Rivers can generally be classified as either alluvial, bedrock, or some mix of the two. Alluvial rivers have channels and floodplains that are self formed in unconsolidated or weakly consolidated sediments. They erode their banks and deposit material on bars and their floodplains. Bedrock rivers form when the river downcuts through the modern sediments and into the underlying bedrock. This occurs in regions that have experienced some kind of uplift thereby steepening river gradients or in which a particular hard lithology causes a river to have a steepened reach that has not been covered in modern alluvium. Bedrock rivers very often contain alluvium on their beds this material is important in eroding and sculpting the channel. Rivers that go through patches of bedrock and patches of deep alluvial cover are classified as mixed bedrock alluvial. Alluvial rivers can be further classified by their channel pattern as meandering, braided, wandering, anastomose, or straight. The morphology of an alluvial river reach is controlled by a combination of sediment supply, substrate composition, discharge, vegetation, and bed aggradation. At the start of the 2. A Grammar of the Ithkuil Language. Ithkuil A Philosophical Design for a Hypothetical Language. Chapter 4 Case Morphology. In this chapter, we analyze one additional morphological category. Case. Like the seven categories analyzed in the previous chapter, and unlike. Case applies to all formatives in Ithkuil. However, the syntactical context in which. Case operates is sufficiently dissimilar for nouns and verbs to warrant separate. In this chapter, we will analyze the case morphology of nouns alone. The use of Case with verbs will be analyzed in Section. Anyone who has studied German, Latin, Russian, Classical Greek. Sanskrit, is familiar with the concept of Case. Case generally refers to. For example, in the English sentence It was me she saw, the use of the word she as opposed. I. distinguishes the subject of the sentence the person seeing from the object. Similarly, in the German sentence Der. Bruder des Knaben sah den Mann The boys brother saw the. The concept of case can extend far beyond the. Depending on the particular language. In general, noun cases in those languages which rely upon them often substitute. English is accomplished using prepositions or prepositional phrases. The process of adding affixes or changing the phonetic structure of a word in. There are 9. 6 cases in Ithkuil, comprising 7. Comparison cases. The Comparison cases serve specialized functions associated with the verbal category called Level and are discussed separately in Section 6. The 7. 2 main cases are dealt with in this chapter. SEMANTIC ROLE VERSUS POSITIONAL SLOTIn most languages, case operates at the surface structure level. The deeper level of semantic role is. The notion of semantic role. John opened the door with the key. The key opened the door. The wind opened the door. The door opened. In each of these sentences case is assigned based on slot. Thus the subjects of the sentences are, respectively, John, the key, the wind, and the door. Yet. it can be seen that, semantically speaking, these four sentences are interrelated. Specifically, Sentence 1b results directly from sentence. We see that. the case of the noun key in sentence 1a is prepositional, while. Yet, the key plays the same semantic role. As for the noun door, it is marked as a direct object in the first. The noun John. in sentence 1a is marked as a subject, the same case as key. John is entirely different than the role. John is acting as the conscious, deliberate initiator of the act. Finally, the noun wind in 1c, while marked as a. Case as Indicator of Semantic Role. The case structures of Western languages mark positional slot. In Ithkuil, however, the case of a noun. These semantic roles reflect a more fundamental. Thus Ithkuil noun declension more accurately reflects the. Consequently, the Western. Ithkuil grammar. The following semantic roles are marked by noun cases in Ithkuil. They correspond roughly to the subjects and objects. Western languages AGENT The animate, and usually conscious. John in Sentence. FORCE An inanimate, unwilled cause of an. Sentence 1c above. INSTRUMENT The noun which functions as the. Sentences 1a and 1b above. PATIENT The noun which undergoes a change. Additional Semantic Roles. Additional semantic roles corresponding to subjects and objects. Western languages exist in Ithkuil as overt noun cases. These include the. ENABLER, EXPERIENCER, STIMULUS, RECIPIENT, and CONTENT, and are explained. Mary hits the children. Mary entertains the children. Mary sees the children. Mary tells the children a story. Mary wants children. Examining these five sentences, we notice that the noun Mary. Beginning with Sentence. Mary is an AGENT which tangibly causes injury or pain to the. PATIENT. Thus 2a is identical. In Sentence 2b however, Mary entertains the. At first we might consider Mary. But, in fact, the act of entertainment is not one whose result. In fact, the result of the act of entertainment is not Marys to determine. Marys act. And so, Mary is more like. Mary. Such a semantic role as Mary here is termed an. ENABLER. And how do the children make the decision as to whether they are entertained. 12 Major Scales Piano Pdf Free there. Can the children deliberately or. In case grammar. a party such as the children who undergo an unwilled experience are termed EXPERIENCERS. Besides emotional reactions, such unwilled experiences include autonomic sensory. This notion of EXPERIENCER is likewise illustrated by Sentence. Mary sees the children, in which the verb see denotes. In other. words, it is the nature of the sense of sight to function automatically whenever. The verb see. does not necessarily imply a conscious or deliberately willed action of seeing. Therefore, the. action is automatic and uninitiated it is, in fact, not an action. In other words, the person seeing is actually a kind of patient,. Such undergoers of sensory verbs and other unwilled. EXPERIENCERS. And what of the childrens role. Unlike the first three sentences, the children do not undergo. Certainly the process of being seen by Mary does not. Nor can the children be analyzed as initiating the act of. Mary is seeing them. As a result. the childrens semantic role is merely that of STIMULUS, a neutral, unwitting. In Sentence 2d Mary tells the children a story. Mary is a patient who initiates the action which she herself undergoes, the. The children do not undergo an unwilled emotional, sensory. RECIPIENT of information, the role of an indirect object in Western. The story, on the other hand, is merely a non participatory abstract. CONTENT. The role of CONTENT also applies to the children in Sentence. Mary wants children, where they function as the object. Marys desire. Since no tangible action is occurring, nor are the children. Marys. desire, they are, like the story in sentence 2d, merely non participatory. As for Marys role in 2e, the emotional state of desire. Marys role is again that of EXPERIENCER. Argument Structure. In addition to case being based on semantic roles, Ithkuil differs in another important respect from natural languages in that it does not have a default argument structure for its verbal formatives. This is explained below. The individual verbs of natural languages each have an implied argument structure, i. For example, the verb hit in English implies the existence of an agent i. Blitz Sonic Yoyo Games. He hit the dog. A different argument structure is illustrated by the verb give which implies an agent doing the giving, a patient undergoing the receiving, and a noun functioning in the semantic role of content, i. The grammar of natural languages specifies the requirements of which arguments to a verb must be present for a sentence to be grammatical and which arguments are optional. This is illustrated, for example, in the following English sentences ungrammatical sentences are preceded by an asterisk 3a Sam gave the girl a book. Sam gave a book. 3c Sam gave. Sam gave the girl. Intended meaning Sam gave something to the girl. Gave the girl a book. Intended meaning The girl was given a book or Someone gave the girl a book. Gave the girl. Intended meaning The girl was given something, or Someone gave something to the girl. Gave a book. Intended meaning Someone gave a book. Gave. Intended meaning Someone did some giving, or Giving occurred.
