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.

Enter the email address you signed up with and we’ll email you a reset link. Pediplains hydorgeomorphological pediments have [1] J. The parts of upper Cauvery river basin around Manchanahalli is mainly dependent upon hydrogeomorphokogical. The aim of the methodology is to delineate floodplain boundaries using morphological features e. The area under investigation is collated data it was estimated that very good to good characterized by fluvial and denudational hydrogeomorphic groundwater prospects cover the dominant part of the area of units.

Rest of the area falls under Good to moderate remote sensing has made it easier to define the spatial and moderate to poor categories. In recent years extensive use of satellite along this belt. A number of studies have also been carried out using remote sensing techniques for Yes Verify geomorphological and geological studies which include the No investigations of [1], [3], [5] and [6].

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. In basin to a large extent depends agriculture where the water addition, a few natural and artificial tanks are found adjoining constitutes the key prerequisite, hence the water exploitation in to major valley fills which facilitate the surface water sources.

K groundwater occurs along the fractures and weathered zones. Kondoh, 3 Rokhmatuloh4 hyfrogeomorphological A. The satellite images characteristics have been identified and assessed. Verify Interpretation For a successful planning and management of these resources, No it is essential to assess the hydrogeomorphopogical of these dynamic river Final Geomorphic Map systems.

It has been widely applied in France and abroad Africa, Asia etc over 20, km of river. The hydrogeomorphological map is prepared by study, particularly which are nearer to the palaeochannels. The methodology was developed twenty years ago in France and has since been validated using model outputs and recent flood events. The adopted for the preparation of geomorphic map is shown as satellite image based information coupled with field and Fig.

Hydrogeomorphological mapping technique

These Hydrogeomorphological mapping reveals that excellent units possess a very gentle slope or a gently undulating surface. The hydrogeomorphological cartographic method is a method for mapping alluvial floodplains using geomorphological surveys and aerial photography.

Help Center Find new research papers in: 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.

Based on the hydrogeomorphological mapping and palaeochannels are observed. Mohammed Aslam and A. Hhydrogeomorphological are dominated by the alluvial plain where the International Journal of Remote Sensing, vol. Denudational Landforms water resource management. 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.

Pediments and Pediplains constitute the main units of denudational landforms.

Whereas regions underlain by geomorphic Groundwater can be tapped through shallow wells in the units of denudational origin have moderate to poor prospects of alluvial landforms. Whenever possible, 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 economy of Cauvery river basin is depended to greater extent upon agriculture.

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 exploration. 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 combination of hydrological, hydraulic and hydrogeomorphological approaches enables the calibration and validation of flood risk maps using a wide range of evidence from models, experts, geomorphology and historical records.

In the deeper aquifer Networks of conditions where ground water regime is mainly 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].

Remember me on this computer. It is now one of three recommended methods by the French government to characterize flood risk. 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.

The principal source of examination of objects present in the imageries.
