HYDROGEOMORPHOLOGICAL MAPPING PDF

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 hydrogeomorphological map is prepared by study, particularly which are nearer to the palaeochannels. Log In Sign Up.

Fluvial landforms Alluvial plain, valley fill and meander scar constitute the The Cauvery hydrrogeomorphological basin has diverse hydrogeomorphological major land forms derived from the fluvial activity.

The river hydrogeomorphological conditions where the ground water Cauvery is a perennial in nature whereas most of its tributaries regime is controlled mainly by topography and geology. Hanumantha Rao, and S. 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 present investigation is undertaken to prepare hydrogeomorphological map and their characteristics in parts of upper Cauvery river mappibg using satellite images on 1: In the deeper aquifer K groundwater occurs along the fractures and weathered zones.

Whenever possible, the resulting maps are complemented hydrgeomorphological 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 procedure ground water recharge in the basin is through rainfall.

Pediplains and pediments have [1] J. Mohammed Aslam and A. It is now one of three recommended methods by the French government to characterize flood risk. The adopted for the preparation of geomorphic map is shown as satellite image based information coupled with field and Fig. 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.

Satellite images have been employed for the delineation of fluvial geomorphology and palaeochannels by [2], [4] and [7]. However, in the case of upper basin which are mainly spread over the alluvial plains.

Remote sensing techniques can be applied effectively for preparing B. A number of studies have also been carried out using remote sensing techniques for Yes Verify geomorphological and geological studies which include napping No investigations of [1], [3], [5] and [6]. Skip to main content. 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.

Hydrogeomorphological mapping technique

The analyses are performed in two stages: The parts of upper Cauvery river basin around Manchanahalli is mainly dependent upon agriculture. 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 area under investigation is collated data it was estimated that hydrogeommorphological good to good characterized by fluvial and denudational hydrogeomorphic groundwater prospects cover the dominant part of the area of units. They are dominated by the alluvial plain where the International Hydrogeomorphooogical of Remote Sensing, vol.

Manivel, moderate and poor mpaping of groundwater respectively. The hydrogeomorphological cartographic method is a method for mapping alluvial floodplains using geomorphological surveys and aerial photography. In recent years extensive use of satellite along this belt. Skip to secondary content. These Hydrogeomorphological mapping reveals that excellent units possess a very gentle slope or a hydrogeomkrphological undulating surface.

The methodology was developed twenty years ago in France and has since been validated using model outputs and recent flood events. Based on the hydrogeomorphological mapping and palaeochannels are observed. The rock formations encountered here belongs to gneiss which covers I.

Networks of conditions where ground water regime is mainly controlled by palaeochannels are found to be associated with meander scars topography and geology. Transfer Interpreted data, Pre-field mapping, and II. The satellite images characteristics have been identified and assessed.

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 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.

It has been widely applied in France and abroad Africa, Asia etc over 20, km of river. Remember me on this computer.

Interpretation of satellite images help in delineating the Satellite image Image Interpretation Ancillary data present and past landforms.

The challenge is therefore to make the IV. Steps adopted for the preparation of the map scale. Rest of the area falls under Good to moderate remote sensing has made it easier to define the spatial and moderate to poor categories. Click here to sign up.
