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).

3. Project Objectives, Deliverables and Monitoring Indicators

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. Monitoring in comparison to the baseline information to be provided by the proponent.
To differentiate the geomorphic factors responsible for GLOF and LLOF type gradation process. Data base on various factors affecting localization in varying case scenario like GLOF and LLOF type gradation process. Geo-referenced Maps and Geomorphic Factors on the selected themes viz., geology, landforms, digital elevation model, slope, drainage patterns, etc. (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. Status and assessment reports for varying case scenarios (Nos.).
The analysis of spatial relation of vulnerable zones with the habitation and major infrastructural growth to understand risk association. Recommendations for disaster risk deduction for important human settlements through analysis of habitation with the landform. Long-term Thematic datasets and cross-correlation patterns of GLOF, LLOF, etc. (Nos)
    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.).
