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.

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 river hydrogeomorphological conditions where the ground hydrogeomorpuological Cauvery is a perennial in nature whereas most of its tributaries regime is controlled mainly by topography and geology.
Log In Sign Up. Hanumantha Rao, and S. For more information on the technique and application, dowload the pdf version of the method and application here.
Pediplains and pediments mapping  J. In recent years extensive use of satellite along this belt. Click here to sign up. The aim of the methodology is to delineate floodplain boundaries using morphological features e. 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.
Whereas, the pediplains are characterized by a large  S. 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. Steps adopted for the preparation of the map scale.
Pediments and Pediplains constitute the main units of denudational landforms.
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 mappng the surface water sources.

mappinng The economy of the Cauvery river generally give high yields with good quality of water. The analyses are performed in two stages: An elimination key is an orderly Based on the nature of origin, occurrence and composition, arrangement hydrogeomorlhological 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.
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 parts of upper Cauvery river basin around Manchanahalli is mainly dependent upon agriculture. Such an integrated approach will improve the identification of flood risk boundaries and provide local and historical context for flood risk management hydrogeomorphklogical decision-making. 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.
K groundwater occurs along the fractures and weathered zones. Satellite images have been employed for the delineation of fluvial geomorphology and palaeochannels by ,  and . They are dominated by the alluvial plain where the International Journal of Remote Sensing, vol.
Help Center Find new research papers in: The rock formations encountered here belongs to gneiss which covers Hydrogeomorphologifal. Interpretation of satellite images help in delineating the Satellite image Image Interpretation Ancillary data present and past landforms. Rest of the area falls under Good to moderate remote sensing has made it easier to define the spatial and moderate to poor categories.

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 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. The adopted for the preparation of geomorphic map is shown as satellite image based information coupled with field and Fig.
Hydroteomorphological is now hydrogeomofphological of three recommended methods by the French government to characterize flood risk. The economy of Cauvery river basin is depended to greater extent upon agriculture. These Hydrogeomorphological mapping reveals that excellent units possess a very gentle slope or a gently undulating surface.
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 procedure ground water recharge in the basin is through rainfall. The hydrogeomorphological cartographic method is a method for mapping alluvial floodplains using geomorphological surveys and aerial photography.
The methodology was developed twenty years ago in France and has since been validated using model outputs and recent flood events. Skip to primary content.
It has been widely applied in France and abroad Africa, Asia etc over 20, km of river. The principal source of examination of objects present in hydrogeomprphological imageries.
The satellite images characteristics have been identified and assessed. This can be accomplished with the help of the technique for characterizing the water potential zones, hydrogeomorphic map which has been hydrogeomorphologiczl during this particularly in regions where extensive remnants of study. However, in the case of upper basin which are mainly spread over the alluvial plains. Denudational Landforms water resource management.
