Discharge - the volume of water moving past a given point in a certain amount of time. Base level is the lowest point to which a stream can erode. This widens the valley and develops features such as floodplains, oxbows, yazoos, etc. Too much water from previous floods, earthquakes, etc. View River Basin Morphometry Research Papers on for free.

For cohesive streambanks, the Channel Evolution Model (Schumm et al. ), shown in Figure 6, provides a good basis for evaluation of potential failure in straight stream reaches. The model shows that if the bank height (h) exceeds the critical bank height (hc), channel widening will continue. Figure 6. Channel evolution phases. The four categories of river regimes are Sinuous canali- form rivers, Sinuous point bar rivers, Sinuous braided rivers, and Non-sinuous braided rivers. The study of river morphology is accomplished in the field of fluvial geomorphology, the scientific term. See also.

Because lake morphometry can play such a critical role in the dynamics of a lake system, we encourage anyone who is interested in learning more about their lake to become familiar with the follow-ing terminology and techniques currently used to study lakes. Such information will provide a solid basisFile Size: 4MB. Lake Morphometry. Maximum length (l) – distance on the lake surface between the two most distant point on the lake shore Maximum width (b) – distance on the lake surface at a right angle to the line of maximum length on a lake Mean width (b) is equal to the area.

Basin analysis, as morphometry form an ideal areal unit for interpretation and analysis of fluvially originated landforms where they exhibits and example of open systems of operation. The composition of the stream system of a drainage basin in expressed quantitatively with stream order, drainage density, bifurcation ration and stream length.

Stream Morphometry Morphometry is defined as the measurement of the shape. Morphometric studies in the field of hydrology were first initiated by R.E. Horton and A.E.

Strahler in the s and s. The main purpose of this work was to discover holisticstream properties from the measurement of various stream attributes.

Description. The book describes the drainage basin as a system unit resulting from the interaction between runoff and topography - a lengthy process of evolution that occurs according to well-defined laws.

It aims not to quantify the agents which created the present forms, but to analyse the forms themselves in order to establish Book Edition: 1. Chapter-IV Drainage Morphometry This chapter deals with the morphometric evolution of drainage network and its characteristics as it applied to normally developed watershed in which running water and associated transported load become most effective.

Emphasis is given upon the geometry,File Size: KB. The trunk stream is the stream segment of highest order. It is found that Karpara river tributaries are of 4th order. In all streams were identified of which 95 are first order, 37 are second order, 12 are third order, and 4 in fourth order.

Drainage patterns of stream network from the. Allometric Analysis and Stream Channel Morphometry. The concept of allometric change, developed and widely applied in biology, is outlined, and the nature of static allometric changes in stream channel size, relative to drainage area, is considered at a variety of scales.

The stream frequency (Sf) is the number of stream segments per unit area (Horton). The ‘Sf’ of the basin is km 2 (Table 1) which displays that the increase in stream population is related to that of ‘Dd’. It is generally controlled by the lithology of the basin and specifies the texture of the stream by: Stream Order (Su): Stream ordering is the first step of quantitative analysis of the watershed.

The stream ordering systems has first advocated by Horton (), but Strahler () has proposed this ordering system with some modifications. Author has been carried out the stream ordering based on the method proposed by Strahler, Table 1 (Figure 3).Cited by: Morphometry is an essential means in geomorphic analysis of an area.

Contour lines that do not "V" or appear notched are not crossed by a stream (Figure 3a). A stream can be traced through five or more successive contour lines with aligned "V's". Streams 1, 4, and 5 on Figure 3b.

A stream can be traced when two, three, or four successive contour lines possess aligned. Tropical geomorphology therefore provides many new discoveries regarding geomorphic processes.

This textbook describes both the humid and arid tropics. It provides thoroughly up-to-date concepts and relevant case studies, and emphasises the importance of geomorphology in the management and sustainable development of the tropical environment Author: Avijit Gupta. Introduction Morphometry is the measurement and mathematical analysis of the configuration of the earth’s surface and of the shape and dimension of its landforms [1].

The form and structure of drainage basins and their associated drainage networks are described by their morphometric parameters.

In classical rift models, deformation is either uniformly distributed leading to symmetric fault bounded basins overlying stretched ductile lower crust (e.g. pure shear McKenzie model) or asymmetric and controlled by large scale detachment faulting (simple shear Wernicke model).

In both cases rifting is considered as a mono-phase process and breakup is instantaneous resulting in the Cited by: The shape, position, and materials of a stream channel cross-section at a specific point. Stream cross-section geometry and characteristics may be monitored at key reaches of scientific or management concern.

Significance. Changes in a channel cross-section can provide readily quantifiable data to determine migration rates, high water marks. The Pennsylvanian rocks of the central Appalachians record a progressive change in paleogeography and paleoenvironment, from extensive sea (Pottsville time), to relatively small bay (Allegheny–lower Conemaugh time), to entirely river-influenced lowsalinity bay-lake (upper Conemaugh–Monongahela time), to relatively small lakes of fluvial plain (Dunkard time).In geomorphology, drainage systems, also known as river systems, are the patterns formed by the streams, rivers, and lakes in a particular drainage basin.

They are governed by the topography of the land, whether a particular region is dominated by hard or soft rocks, and the gradient of the land.The influence of lake morphometry on sediment focusing Jules M.
