Project Brief Description: |
In the higher Himalayan terrain, the gradation process during extreme events is responsible for the growth of ephemeral landforms including Glacial Lake Outburst Flood (GLOF) and Landslide Lake Outburst Flood (LLOF). No systematic study exist in this region identifying the characteristic geomorphology and numerical modeling of morphometric parameters establishing link between observation and gradational processes, which is critical to understand landform growth and any hazard assessment related to it. Therefore, aim of this project is to understand the climate-tectonic interaction in landform growth, generate scenario conditions and identifying optimal scale of catchment prone for flash floods (with specific reference to the GLOF and the LLOF) and associated mass wasting in upper Ganga catchment in Garhwal Himalaya. The major outcomes of the project are: developing up-to-date database and new methodology for analysis of digital data, which can be replicated to similar terrain for vulnerability analysis. The findings of the project will be sharedwith the local population across gender through outreach program with Gram Panchayat and JillaParishad. The project falls under the broad thematic group-'Conservation and sustainable use of biodiversity' of the National Mission on Himalayan Studies (NMHS). |

Project Objectives |
Quantifiable Deliverables |
Monitoring Indicators |
|
Geomorphic characterization and correlation of pilot catchments affected by flash floods and debris flow during last century in Garhwal Himalaya |
Geo-referenced maps on different themes that include litho-tectonics / geology, landforms, digital elevation model, slope, relief, drainage pattern, basin/catchment asymmetry and various morphometric parameters computed from above thematic spatial and vector dataset generated by extensive field mapping and numerical simulations. |
Geo-referenced Maps and Geomorphic Factors on the selected themes viz., geology, landforms, digital elevation model, slope, drainage patterns, etc. (Nos.). |
|
To differentiate the geomorphic factors responsible for GLOF and LLOF type gradation process. |
Analysis and cross correlation of various thematic dataset in space and longitudinal section to understand factors affecting localization in varying case scenario like GLOF and LLOF type gradation process. |
Status and assessment reports for varying case scenarios (Nos.). |
|
Integrate the numerical simulation with the field observation and dating of landforms to generate recurrence interval, understand paleoclimate interventions and generate model scenario. |
Dating of at least 2 old landforms to build geological history and recurrence, where possible. |
Long-term Thematic datasets and cross-correlation patterns of GLOF, LLOF, etc. (Nos) |
|
The analysis of spatial relation of vulnerable zones with the habitation and major infrastructural growth to understand risk association. |
Overlay and analysis of habitation with the landform to understand risk and develop vulnerability maps for all selected sites. |
Dating of old landforms to form geological history of the selected sites along with communities engaged in monitoring programmes (Nos.); |
| |
|
Vulnerability maps created through overlay and habitation analyses of Landforms and Geomorphic Factors (Nos.). |
