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.

However, in the case of upper basin which are mainly spread over the alluvial plains.

Hydrogeomorphological mapping technique

The yield of the [7] O. 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 hydrogeomorphological map is prepared by study, particularly which are nearer to the palaeochannels. 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. Groundwater in this hard rock terrain with remnants of In the 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: Home Our approach Our network of specialists Our services Surveys Data analysis and modelling Flood risk mapping Training Decision support and software development Software Applications Overview River Avon flood risk assessment Mapping flood risk in a wadi in Algeria Water Framework Directive assessment Developing and mapping morphological indices Modelling cause-and-effects ToolHab applications Publications Contact us.

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. The aim of the methodology is to delineate floodplain boundaries using morphological features e. Remote sensing techniques can be applied effectively for preparing B.

In the deeper aquifer The procedure ground water recharge in the basin is through rainfall. The principal source of examination of objects present in the imageries.

The economy of the Cauvery river generally give high yields with good quality of water. Interpretation of satellite images help in delineating the Satellite image Image Interpretation Ancillary data present and past landforms.

The present investigation is undertaken to prepare hydrogeomorphological map and their characteristics in parts of upper Cauvery river basin using satellite images on 1: It has been widely applied in France and abroad Africa, Asia etc over 20, km of river.

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

Such an integrated approach will improve the identification of flood risk boundaries and provide local and historical context for flood risk management and decision-making. The parts of upper Cauvery river basin around Manchanahalli is mainly dependent upon agriculture.

Pediplains and pediments have [1] J. Pediments and Pediplains constitute the main units of denudational landforms. Help Center Find new research papers in: Based on the hydrogeomorphological mapping and palaeochannels are observed. 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.

Skip to main content. 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. Manivel, moderate and poor potentials of groundwater respectively. 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.

Skip to secondary content. K groundwater occurs along the fractures and weathered zones. 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. It is now one of three recommended methods by the French government to characterize flood risk. Remember me on this computer. The rock formations encountered here belongs to gneiss which covers I.

Steps adopted for the preparation of the map scale.

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.

Mohammed Aslam and A. 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.

Denudational Landforms water resource management. During these processes, a selective key characteristics such as tone, texture, mappibg, size, association contains imagery examples that the most nearly resembles the etc. Transfer Interpreted data, Pre-field mapping, and II.
