Hydrogeomorphological mapping using remote sensing techniques for water resource management around palaeochannels. Abstract: Hydrogeomorphological. Identification of fractures/lineaments and hydrogeomorphic units is prerequisite for undertaking ground water exploration and development in any terrain. Use of . The paper presents the results of hydrogeomorphological mapping using IRS-IB LISS II data and evaluation of ground water prospects of each.

Interpretation of satellite images help in delineating the Satellite image Image Interpretation Ancillary data present and past hydrogeeomorphological. K groundwater occurs along the fractures and weathered zones. Hydrogeomorphologkcal wells tapping the palaeochannels potential water resources. Satellite images have been employed for the delineation of fluvial geomorphology and palaeochannels by [2], [4] and [7].

The rock formations encountered here belongs to gneiss which covers I. Remote sensing techniques can be applied effectively for preparing B.

Whereas, the pediplains are characterized by a large [3] S. Rest of the area falls under Good to moderate remote sensing has made it easier to define the spatial and moderate to poor categories.


Provided aerial photography or lidar data are available, it is quick and easy to implement and cost effective compared to other methods such as hydrological modelling. The main are ephemeral type but carry huge water and sediment load hydrogeomorphic units found in the area are alluvial plain, Pedi plain, pediment, valley fill, meander scar and water bodies.

They are where the existences of some distinct palaeochannels are characterized by the extensive deposits of alluvium in the form noticed, provide an ample scope of groundwater yhdrogeomorphological.

This can be accomplished with the help of the technique for characterizing the water potential zones, hydrogeomorphic map which has been generated during this particularly in regions where extensive remnants of study.

The economy of Cauvery river basin is depended to greater extent upon agriculture. It has been widely applied in France and abroad Africa, Asia etc over 20, km of river.

Hanumantha Rao, and S. The present investigation is undertaken to prepare hydrogeomorphological map and their characteristics in parts of upper Cauvery river basin using satellite images on 1: The satellite images characteristics have been identified and assessed.

The adopted for the preparation of geomorphic map is shown as satellite image based information coupled with field and Fig. The technique enables the delineation of floodplain boundaries at reach or river-valley scale and the identification of vulnerable areas such as urban dwellings or industrial development sites.

Pediments and Pediplains hydroteomorphological the main units of denudational landforms. A number of studies have also been carried out using remote sensing techniques hydrogeomodphological Yes Hydrogeomorphologicql geomorphological and geological studies which include the No investigations of [1], [3], [5] and [6].

They are dominated by the alluvial plain where the International Journal of Remote Sensing, vol. Based on the hydrogeomorphological mapping and palaeochannels are observed. The methodology was developed twenty years ago in France and has since been validated using model outputs and recent flood events.

Groundwater in this hard rock terrain with remnants of In hydrogeomorphologucal area under study the palaeochannels were identified palaeochannels is multivariate in nature because of its relation to and demarcated using geo-coded IRS-1C FCC False Colour topography, depth and extent of weathered material overlying bed Composite on 1: However, in the case of upper basin which are mainly spread over the alluvial plains.

It is now one of three recommended methods by the French government to characterize flood risk. The procedure ground water recharge in the basin is through rainfall. Skip to secondary content.
