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]. Determine pre-and post-developed basin characteristics 2. Herein, the number of streams gradually decreases with increase in stream order. Fluvial morphometric study includes the consideration of linear, areal and relief aspects of the fluvially originated drainage basin. morphometric analysis of drainage basin. The results of Morphometric analysis revealed that the total number of stream is 44 with total length of drainage is 30.2 km. Grey areas are endorheic basins that do not drain to the oceans. and a vague and possibly unreliable analysis is obtained. The characteristics that were used in this study to evaluate the drainage-area ratio method were drainage … 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) It is an open system as it has inputs and outputs. However, the present burst of activity in hydrologic simulation is a direct result of widespread availability of the computer. 4 0 obj Table 1.1 Applications of the Recommended Hydrologic Methods Method Technical Manual Section Rational Method SCS Method Modified Rational Snyder’s Unit Hydrograph USGS / endobj 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) The attributes were allocated to generate the digital data base for drainage layer of the river basin. The drainage basin analysis is important in any hydrological investigation like assessment of groundwater potential and groundwater management. The basins were studied by examining the relations of drainage area, discharge, and length of stream from drainage divide. Drainage basins, catchments and sub-catchments are the fundamental units for the management of land and water resources (Moore et al.

A systematic classification of large rivers based on their hydrosedmentary components i 2 0 obj Average drainage density of watershed is 2.837km / km 2 and the average frequency is 3.743 Complete rainfall-runoff simulation models date back at least to the 1920's. 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. Digitization of the drainage basin was carried out for morphometric analysis in GIS environment using Arc GIS-10 software. A drainage basin system is one part of the hydrological cycle. Urban Drainage and Flood Control District of drainage basins to basin-runoff characteristics have been described by Langbein (1947, p. 128-129). %���� An individual drainage basin (a.k.a. %PDF-1.5 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. 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. Remote sensing and Geographical Information System (GIS) techniques are increasingly being used for morphometric analysis of drainage basins throughout the world [9–13]. The Daluaghat basin has a dendritic to parallel drainage pattern. 06/2001 DE-7 . 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 The mean bifurcation ratio is 1.53 and dendritic drainage pattern with ranging from coarse to fine texture is identified. The primary step in drainage basin analysis is to designate order. It follows, the drainage basin is formed by a network of channels (streams) which form the valleys (longitudinal depressions between basins, model predictions vs. observations) zTopology versus topography – Topological variables represent network structure – Implies that two basins may look utterly different but be catchment or watershed) is a finite area whose runoff is channeled through a single outlet. 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: Enter the email address you signed up with and we'll email you a reset link. basin area, runoff coefficients, and rainfall intensity into the Rational Method equation, Q=CIA. The drainage basin (watershed) is the fundamental earth surface expression that collects and distributes water and sediment. Academia.edu no longer supports Internet Explorer. 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 … Design detention as required 5.

Morphometric parameters and climatic 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. 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. structure that is either undersized and causes more drainage problems or, is oversized and costs more than necessary. 1 0 obj properties of Oluyole drainage basin induced high, medium and low magnitude flood. The results revealed that the used of remotely sensed data and ArcGIS 10.0 software provide an effective approach to develop accurate morphometric analysis of drainage basin … results of all hydrologic analysis. 6.2.6 Evaluation of Runoff Factors . Title: No Slide Title _In the present study, morphometric analysis of the Galagu valley basin was done to produce information on the morphometry of the Galagu valley basin and to assess its hydrological characteristics and flood potentials. 3 0 obj 1.

A flood hydrograph shows how a river’s discharge changes in response to a rainfall event. Application of quantitative techniques in morphometric analysis of drainage basins was initially undertaken by Horton et al. Morphometric analysis in a drainage basin is important for hydrological investigation and development and management of drainage basin (Rekha et al. Drainage basins of the principal oceans and seas of the world. On the other hand, any hydrologic analysis is only an approximation. The shape of a flood hydrograph is influenced by a range of physical and human factors. Sorry, preview is currently unavailable. 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.

Ocean basins. Morphometric analysis of a basin provides information about different aspect and characterizes the drainage system of basin in these aspects (Strahler A. N., 1964). 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. 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. In its simplest form, a drainage basin is an area that funnels all runoff to the mouth of a stream. Determine basin … The fundamental unit of virtually all watershed and fluvial investigations is the drainage basin.
