Apart from this, a small basin is com- monly much less complicated than a large basin with respect to geology and topography; there- 1 fore, it lends itself much better to both practi- , cal and theoretical studies.

Application of quantitative techniques in morphometric analysis of drainage basins was initially undertaken by Horton et al. The parameters considered for analysis are stream length, bifurcation ratio, drainage density, stream frequency, Drainage texture, form factor circularity ratio, elongation ratio, compactness ratio etc. • The time of concentration (tc) is the time required for water to travel from the hydraulically most remote point of %���� In its simplest form, a drainage basin is an area that funnels all runoff to the mouth of a stream. Morphometric analysis of a drainage pattern needs the demarcation of all the existing streams.

For all hydrologic analyses, the following factors should be evaluated and included when they will have a significant effect on the final results: • Drainage basin characteristics including: size, shape, slope, land use, geology, soil type, surface infiltration, and storage Academia.edu no longer supports Internet Explorer. [2–8] from topographic maps using manual methods. qualitative analysis of the morphometric characteristics of these basins (i.e., stream order, stream length, bifurcation ratio, drainage density, drainage frequency, relief ratio, elongation ratio, basin shape and form factor ratio) has been carried out. endobj Determine basin … Morphometric parameters and climatic metric analysis of drainage basins throughout the world [ ]. Enter the email address you signed up with and we'll email you a reset link. <> Morphometric parameters of these twelve catchments were Drainage basin, also called catchment area, or (in North America) watershed, area from which all precipitation flows to a single stream or set of streams. and a vague and possibly unreliable analysis is obtained. 4.1 Morphometric analysis of basin: Morphometric Analysis of a watershed provides a quantita-tive description of the drainage system which is an im-portant aspect of characterization of watersheds (Strahler, 1964). basin area, runoff coefficients, and rainfall intensity into the Rational Method equation, Q=CIA. 2011). The basins were studied by examining the relations of drainage area, discharge, and length of stream from drainage divide. It is the 5th order drainage basin. The relationship between the amount of precipitation into a drainage basin and the amount of runoff from the basin is complex, and too little data are The primary step in drainage basin analysis is to designate order. Urban Drainage and Flood Control District 1 Basin Analysis Basin Analysis Introduction Mechanisms of Basin Formation Basin Classification Basins and Sequence Stratigraphy Summary Introduction Basin analysis - Study of sedimentary rocks to determine: Subsidence history Stratigraphic architecture Paleogeographic evolution Tools: Geology (outcrops, wireline logs, core) Geophysics (seismic, gravity, aeromag) Morphometric analysis of a basin provides information about different aspect and characterizes the drainage system of basin in these aspects (Strahler A. N., 1964). Quantitative techniques have been applied to study the morphometricpropertiesofdi erentdrainagebasinsinIndia [ ]. The various above morphometric parameters such as linear, areal and relief aspect were used for this present studies: The shape of a flood hydrograph is influenced by a range of physical and human factors. 2 0 obj Ocean basins. structure that is either undersized and causes more drainage problems or, is oversized and costs more than necessary. Digitization of the drainage basin was carried out for morphometric analysis in GIS environment using Arc GIS-10 software. Determine if detention is needed 4. Hypsometry of drainage basins (area–elevation analysis) has generally been used to infer the stage of geomorphic development and to study the influence of varying forcing factors (i.e. Hydrological Analysis HO-2 April 2010, Revised 9/2014 the drainage basin or where other drainage characteristics indicate general regression equations might not be appropriate. 1994). Remote sensing and Geographical Information System (GIS) techniques are increasingly being used for morphometric analysis of drainage basins throughout the world [9–13].

By doing so a number applications of HATWAB can be sought that include mainly: 1) Assessment of water availability and distribution in a drainage basin; and 2) hydrograph analysis are mathematical modeling. 1 0 obj of drainage basins to basin-runoff characteristics have been described by Langbein (1947, p. 128-129). Determine the basins of the 10% analysis point and all intermediate locations of concern 6. The Daluaghat basin has a dendritic to parallel drainage pattern. The drainage basin (watershed) is the fundamental earth surface expression that collects and distributes water and sediment. P. Arulbalaji, D.

Sorry, preview is currently unavailable. It is an open system as it has inputs and outputs. The results of Morphometric analysis revealed that the total number of stream is 44 with total length of drainage is 30.2 km.

Compute pre-and post-developed peak discharges 3. temporal variability basin water budget in terms of soil moisture, actual evapotranspiration, runoff, and vertically integrated moisture convergence. catchment or watershed) is a finite area whose runoff is channeled through a single outlet. Herein, the number of streams gradually decreases with increase in stream order. Table 1.1 Applications of the Recommended Hydrologic Methods Method Technical Manual Section Rational Method SCS Method Modified Rational Snyder’s Unit Hydrograph USGS / Statistical analysis aids in reducing this complexity in drainage basin research [26] [27], using a wide variety of pattern recognition operations, such as factor analysis, principal component analysis, cluster analysis, and dis-criminant analysis [28]. The mean bifurcation ratio is 1.53 and dendritic drainage pattern with ranging from coarse to fine texture is identified. For the streams investigated, excellent correlations were found to exist between drainage area and the 2.3-year flood, as well as between length of stream from the basin divide and drainage … On the other hand, any hydrologic analysis is only an approximation. 3 0 obj It follows, the drainage basin is formed by a network of channels (streams) which form the valleys (longitudinal depressions Figures 6 and 7 show the 10-year and 100-year peak discharges into the detention pond from the 104-acre drainage basin to be 131 cfs and 250 cfs, respectively. determined and computed. Drainage Basin Morphometry zMorphometry – The quantitative measurement of form – Provides a systematic basis for description and comparison (e.g. 6.2.6 Evaluation of Runoff Factors . Watershed Analysis RATIONALMETHOD Assumptions and Limitations: • Watershed area < 200 acres • The method is applicable if time of concentration (tc) for the drainage area is less than the duration of peak rainfall intensity. <>>> Therefore, analysis of the drainage basin helps to understand the landform evolution through successive stages of geological time, fluvial process, lithologic character and hydrological behaviour of a basin as well as tectonic activity of a region. Drainage basins, catchments and sub-catchments are the fundamental units for the management of land and water resources (Moore et al. between basins, model predictions vs. observations) zTopology versus topography – Topological variables represent network structure – Implies that two basins may look utterly different but be The attributes were allocated to generate the digital data base for drainage layer of the river basin. You can download the paper by clicking the button above. The fundamental unit of virtually all watershed and fluvial investigations is the drainage basin. A drainage basin system is one part of the hydrological cycle. The topographic parameters considered important in these studies were: area, channel slope, stream pattern, average basin width, mean length of travel (channel length), and … However, the present burst of activity in hydrologic simulation is a direct result of widespread availability of the computer.
