    1 : 1 Namaste!!! NEPAL
    2 : 2 HydroMeteorological Activities in Nepal Dept. of Hydrology Meteorology NEPAL
    3 : 3 Nepal: Location Area: 147,181 km2 Length: ~850 km EW Width: ~200 km NS Altitude:~ 60-8848 m 26º 22' N - 30º 27' N Lat. 80º 4'E - 88º 12'E Long.
    4 : 4 Nepal: Topographic
    5 : 5 Nepal: Physiographic
    6 : 6 Nepal: Physiographic Terai Region (Gangetic Plain) Siwaliks Region Middle Mountain Region High Mountain Region Higher Himalayas
    7 : 7 Nepal: Climate Tropical Climate ?Terai Cool temperate and alpine climate?Himalayan ranges Terai?hottest part, summer temp. may rise as high as 40oc and is hot and humid, winter temp. 7o-23oc Mountains?mild summer with temp. around 25-27oc, sub-zero to 12oc in winter Himalayas? frigid climate Kathmandu valley?pleasant climate with avg. summer temp. of 19-27oc & 2-12oc winter temp.
    8 : 8 Nepal: Climate (contd.) Rainfall is extensive (~80% of the annual) during the south-west monsoon period (June to August) with eastern part receiving max. In the winter, the western part receives a larger portion of rainfall Annual Precipitation Plain area ?1500 mm or less Foot of the Siwaliks ? >2000 mm Northern side of Mahabharat? 1000 mm Middle/High Mountain?few PTN zones exceeds 5000 mm Himalayas?decreases up to 300 mm
    9 : 9 DHM (Dept. of Hydrology & Meteorology) Government Organization under Ministry of Science and Technology Has mandate from HMG/N to monitor all hydrological and meteorological activities in Nepal No agency is entitled to carry out such activities without a proper liaison with DHM Member of WMO Actively participates in the program relevant international organizations such as UNESCO’s IHP and WMO’s OHP etc…
    10 : 10 DHM: Activities Hydrological and Meteorological activities were started in an organized manner in 1962 DHM has been upgraded to department status in 1988 Current Projects under DHM River Hydrology Meteorology Weather forecasting Flood Forecasting Snow & Glacier Hydrology Tsho-Rolpa GLOF Risk Reduction Project

    16 : 16 Disasters: Facts & Figures Types of Hazards: Drought/famines, Earthquakes, Epidemics, Floods and Wind Storms Largest killer: Wind Storms (88.36%, as % of people killed due to disasters) Most occurring disaster: Wind Storms (48.02%, as a % of all disasters) Largest affecter: Floods (79.59%, as % of all affected) Annual frequency of all disasters: 6.56 Annual frequency of wind storms: 3.15 Annual frequency of floods: 1.78 Source: http://www.southasianfloods.org
    17 : 17 Nature of Floods in Nepal Flash Flood Inundation of Plain Area Urban Flooding Source: http://www.southasianfloods.org
    18 : 18 DHM towards Flood Forecasting Wireless Data Transmission Data Sharing with neighboring countries-India & Bangladesh Tsho Rolpa Risk Reduction and Early Warning System Initiated to calibrate easily available R-R models HFAM TOP, Tank, Xinanjinag, ANN, ADM etc. Results are not encouraging for flood peaks
    19 : 19 Problems No real time data transmission system Flood with landslides: Difficult to predict landslide Scouring and siltation of river beds: difficult to operate automatic recorder
    20 : 20 Flood Forecasting System Long way to go !!!
