नदीको जलप्रवाह नाप्ने तरिका रोचक छ । बगिरहेको नदीमा नुन खन्याएर नापिन्छ । लाङटाङ नदीमा जलप्रवाह नाप्न पुगेको टोलीले नुन खन्याएर जलप्रवाह नापेका छन् ।
This is how we add salt and measure river discharge. Another person ( Abhijit Vaidya in this experiment) will measure concentration of salt as electrical conductivity at a point downstream of the injection point making sure that the injected salt is well mixed.The method is based on conservation of mass and is commonly know as Dry Injection OR mass balance method. #ICIMOD #Langtang_khola #Monsoon_Expedition #River_discharge_measurementVideo credit and special support: Gyalbu dai Gyalbu Langtang
