Snow melt


  This small program aims to create an estimate of the expected increase in water levels in catchment areas that you mark out this map (using a ruler) Map. I chose this card because of two very important benefits: – clear embossed image – very good "Measuring distances"-ruler – as well as maintenance of the Bulgarian language.

Wikimapia---Lets-describe-the-whole-[3]

 An important feature is that the first opening of the card is not in this form, so the menu: Map type / kind of map /-tick – satellite . To find the right place, move and zoom the map when you find out you are interested click on the ruler – then you will see this:

 Start to mark out your interest catchment areas, always start from the horizontal (parallel) of the water catchment area stretches for the program to work correctly – it will calculate the volume of water quantity in the form of snow like this:2-Wikimapia---Lets-describe-the-whol

    In the picture, I marked the horizontal sections, a1, a2, a3, a4, and are vertical; b1, b2, b3, b4. Record the data in the program by converting measured distances from km to m (2.5 km = 2500 m / 1.2 km = 1200m) The program will need to apply and the average thickness of the snow that measured in centimeters, use the following conversion dependencies (100 cm = 1 m; 10cm = 0.1 m; 5 cm = 0.05 m) Window on the program:snow-1_thumb1

   It is not necessarily to fill in all data areas, but not necessarily enter the average thickness of the snow after you enter data and click the "calculate" the program will calculate the total water amount accumulated in the form of snow, using the relationship: 5 volume parts snow = 1 parts water (this is the ratio of unbeaten snow)

  The program will display the depth of the water catchment area with a width of 20 meters, as shown in the above screenshot. For correct operation of the program, it is important to correctly apply the horizontal sections in the area, a1, a2, a3, a4 …..!Graphic2_thumb1

  The program is indicative, it can be used to calculate the estimated amount of water that will flow in the water catchment area area during the summer rains, as predicted rainfall  l / m2 move in snow field, and the ratio 1/5 is "the amount of water "you will be asked in the soil or evaporated into the atmosphere.

  The program at this stage is static because it does not measure the dependence of increased average night and day temperatures and increase the speed of snow melting as well as changing the structure and color of the snow (because then it reacts differently to solar radiation) so if anyone possession of such information depends on : increasing temperature – snowmelt-LET share it as a comment or a personal email to me.

  If you entered the relationship: speed of snowmelt – increasing average temperature day and night, then you can predict the height of the the shock wave of water that would be formed in a sharp increase in temperature!

   The program is open source, anyone can copy it and convert to their own needs!             I apologize for the wooden transfer, however, English is not my mother language!

I will be happy if you useful this program!
