2. Qgis [ quantum geographical information system] QGIS is a free and open-source cross-platform desktop geographic information system application that supports viewing, editing, printing, and analysis of geospatial data. Geographic information systems (GIS) are used in a wide range of academic and applied fields. Simply put, GIS allows you to combine tabular data (e.g. spreadsheet sheet) with geographic boundaries (e.g. maps). There are also numerous plugins, that extend the functionality of QGIS . Why QGIS ? It’s Free. Its developing conctantly . Extensive help and documentation are available . Cross Platform .

4. WHY DO WE do WATERSHED DELINEATION ? Watershed delineation is  the process of identifying the boundary of a watershed, also referred to as a catchment, drainage basin, or river basin . It is an important step in many areas of environmental science, engineering, and management, for example to study flooding, aquatic habitat, or water pollution. After a watershed is properly delineated, engineers can calculate the drainage area, slope and land cover. These characteristics along with other factors will affect the time it takes rainwater to travel from the delineation boundary to the downstream outfall How to Delineate Watershed : Create a Filled DEM [Fill sink ( wang and Liu)] Aspect , Hillshade , Contours . Strahler Order and Raster Calculation. Flow Accumulation. Channel Network & Drainage Basins.

5. 1. Bageshwar : The District of Bageshwar came into existence on 15th September, 1997. Bageshwar is one of the mountainous districts of Uttarakhand State. The district lies between latitudes 29º40' and 30º20' N and longitudes 79º25' and 80º10' E (Survey of India Degree Sheet Nos. 53N and 53O). The district is bounded by Almora district in the south, Chamoli district in the north and northwest and Pithoragarh district in the east. The geographical area of the district is 2282 km 2 . The climate in Bageshwar district is temperate to sub - humid. Most rainfall (about 75 percent) occurs during the monsoon months of June to September. Rice is the major crop grown in 38% of the net sown area closely followed by wheat, which is grown in 35% of the area. Apart from this, other major crops are mandua (18%), barley (6%), sawan (2%) and maize (1%). Major sources to develop irrigation potentoial are Gomti , Saryu and Pindar Rivers and some of their tributaries like Pungar Nadi.

6. The total irrigation potential created through the lift schemes is 816 ha while the irrigation potential actually used by them is 610 ha (74.75% of the total potential) Drainage of the area is mainly controlled by Saryu, Gomti and Pindar Rivers and their tributaries (locally called Nadi, Gad or Gadhera ). The Central and North-Central parts of the district are drained by Saryu River. Gomti River drains the western and south eastern parts whereas Pindar River drains the northern part. The soils of Bageshwar district can be broadly classified into two types, viz. Soils of Lesser Himalaya and Soils of Greater or Central Himalaya. The soils of Lesser Himalaya are further subdivided into a) Soils of Summits and Ridge tops, b) Soils of Side Slopes, c) Soils of Glacio-Fluvial Valleys, d) Soils of Fluvial Valleys and e) Soils of Cliffs.   The soils of Greater Himalaya have been broadly classified under a) Soils of Summits, Ridge Tops and Mountain Glaciers, b) Soils of Side Slopes, c) Soils of Upper Glacio-Fluvial Valleys and d) Soils of Cliffs.

7. Materials and methods : Data collection Adding raster layer and merge it Adding vector layer and select the district Clip the selected area and reproject it and set CRS Now make dem maps of Slope , Contours , Aspect , Hillshade Go to Saga next gen Fill sink ( wang and liu ) Strahler order Raster calculator of Strahler order Flow accumulation Drainage Basins and Channel Networks
