The results of Morphometric analysis revealed that the total number of stream is 44 with total length of drainage is 30.2 km. The basins were studied by examining the relations of drainage area, discharge, and length of stream from drainage divide.

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) 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). However, the present burst of activity in hydrologic simulation is a direct result of widespread availability of the computer. Quantitative techniques have been applied to study the morphometricpropertiesofdi erentdrainagebasinsinIndia [ ]. Parameters worked out include Tectonophysics, 194 (1991) 237-263 Eisevier Science Publishers B.V., Amsterdam 237 Principles of drainage basin analysis from multisource data: Application to the structural analysis of the Zaire Basin B. Deffontaines and J. Chorowicz Laboratoire de Gtectonique, UniversitPierre et Marie Curie, U.P. endobj of drainage basins to basin-runoff characteristics have been described by Langbein (1947, p. 128-129). Morphometric analysis of a drainage pattern needs the demarcation of all the existing streams. x��=�n�F���|:�YH��[�%�:���>��@�P#�G3�e������n�͡�8 $�4�������M_��u�j�x޶��^G�_|�������]}�K�ivU��wϞE/^��^|x���5��}�~��E �ϢTF��q ��O�$��y���E��w��ǧO~��j��NÇ��~��b�[�û��E�����ߞ"��S%x�e$�8+h�(��D������ �B1�8�o��b�k��"�~\f�{�L��)z���]����r\-�3�z���î Application of quantitative techniques in morphometric analysis of drainage basins was initially undertaken by Horton 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 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. 1. A systematic classification of large rivers based on their hydrosedmentary components i The attributes were allocated to generate the digital data base for drainage layer of the river basin. Drainage Basin Morphometry zMorphometry – The quantitative measurement of form – Provides a systematic basis for description and comparison (e.g. 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 … The drainage basin analysis is important in any hydrological investigation like assessment of groundwater potential and groundwater management.
