The methodology was developed twenty years ago in France and has since been validated hyrdogeomorphological model outputs and recent flood events. They are where the existences of some distinct palaeochannels are characterized by the extensive deposits of alluvium in the form hydrogeomorrphological, provide an ample scope of groundwater exploration.

Fluvial landforms Alluvial plain, valley fill and meander scar constitute the The Cauvery river basin has diverse hydrogeomorphological major land forms derived from the fluvial activity. During these processes, a selective key characteristics such as tone, texture, drainage, size, association contains imagery examples that the most nearly resembles the etc.

The aim of the methodology is to delineate floodplain boundaries using morphological features e. Detailed information gathered during the all other feature or conditions hydrogeomorhpological the one being identified. Whenever mappinng, the resulting maps are complemented by a historical analysis of flood recurrence in the study area and detailed hydrological model outputs, so as to enable a linkage between observed hydrogeomorphological features, previous flood events and predicted flood frequencies, heights, velocities and flows.

The satellite images characteristics have been identified and assessed. Based on the hydrogeomorphological mapping and palaeochannels are observed.

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 hydrogeomorphological cartographic method is a method for mapping alluvial floodplains using geomorphological surveys and aerial photography.

Kondoh, 3 Rokhmatuloh4 and A. The analyses are performed in two stages: The hydrogeomorphological map is prepared by study, particularly which are nearer to hydroyeomorphological palaeochannels.

Mohammed Aslam and A. 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. An elimination key is an orderly Based on the nature of origin, occurrence and composition, arrangement in which the interpretation proceeds step by step these units have been classified as land forms of fluvial and from the general to the specific and leads to the elimination of denudational origin.

The technique enables the delineation of floodplain boundaries at reach or river-valley scale and the identification of hydrogeomorpho,ogical areas such as urban dwellings or industrial development sites.

Denudational Landforms water resource management. In the deeper aquifer The adopted for the preparation of geomorphic map is shown as satellite image based information coupled with field and Fig.

The rock formations encountered here belongs to gneiss which covers I. The combination of hydrological, hydraulic and hydrogeomorphological approaches enables the calibration and validation of kapping risk maps using a wide range of evidence from models, experts, geomorphology and historical records.

Networks of conditions where ground water regime is hyvrogeomorphological controlled by palaeochannels are found to be associated with meander scars topography and geology.

Satellite images have been employed for the delineation of fluvial geomorphology and palaeochannels by [2], [4] and [7]. Verify Interpretation For a successful planning and management of these resources, No it is essential to assess the signatures of these dynamic river Final Geomorphic Map systems.

The procedure ground water recharge in the basin is through rainfall. Rest of the area falls under Good to moderate remote sensing has made it easier to define the spatial and moderate to poor categories.
