QUICK TIPS (--THIS SECTION DOES NOT PRINT--) This PowerPoint template requires basic PowerPoint (version 2007 or newer) skills. Below is a list of commonly asked questions specific to this template. If you are using an older version of PowerPoint some template features may not work properly. TEMPLATE FAQs Verifying the quality of your graphics Go to the VIEW menu and click on ZOOM to set your preferred magnification. This template is at 100% the size of the final poster. All text and graphics will be printed at 100% their size. To see what your poster will look like when printed, set the zoom to 100% and evaluate the quality of all your graphics before you submit your poster for printing. Modifying the layout This template has four different column layouts. Right-click your mouse on the background and click on LAYOUT to see the layout options. The columns in the provided layouts are fixed and cannot be moved but advanced users can modify any layout by going to VIEW and then SLIDE MASTER. Importing text and graphics from external sources TEXT: Paste or type your text into a pre-existing placeholder or drag in a new placeholder from the left side of the template. Move it anywhere as needed. PHOTOS: Drag in a picture placeholder, size it first, click in it and insert a photo from the menu. TABLES: You can copy and paste a table from an external document onto this poster template. To adjust the way the text fits within the cells of a table that has been pasted, right-click on the table, click FORMAT SHAPE then click on TEXT BOX and change the INTERNAL MARGIN values to 0.25. Modifying the color scheme To change the color scheme of this template go to the DESIGN menu and click on COLORS. You can choose from the provided color combinations or create your own. QUICK DESIGN GUIDE (--THIS SECTION DOES NOT PRINT--) This PowerPoint 2007 template produces a 91cm x 122cm professional poster. You can use it to create your research poster and save valuable time placing titles, subtitles, text, and graphics. We provide a series of online tutorials that will guide you through the poster design process and answer your poster production questions. To view our template tutorials, go online to PosterPresentations.com and click on HELP DESK. When you are ready to print your poster, go online to PosterPresentations.com. Need Assistance? Call us at 1.866.649.3004 Object Placeholders Using the placeholders To add text, click inside a placeholder on the poster and type or paste your text. To move a placeholder, click it once (to select it). Place your cursor on its frame, and your cursor will change to this symbol. Click once and drag it to a new location where you can resize it. Section Header placeholder Click and drag this preformatted section header placeholder to the poster area to add another section header. Use section headers to separate topics or concepts within your presentation. Text placeholder Move this preformatted text placeholder to the poster to add a new body of text. Picture placeholder Move this graphic placeholder onto your poster, size it first, and then click it to add a picture to the poster.

Snow and ice melt contributing to the discharge of river in 2013 is 41.3 %. Projected discharge of the basin (2015 – 2050) shows increase in river discharge by 0.013 m 3 s -1 year -1 with the decrease in snow-ice melt contribution resulting to 34.8 % in 2050. This model gives insights into the hydrological system dynamics of the glacerized basin with the contribution of snow and ice melt in discharge and also estimates the water availability of the Himalayan region.
