1. Ganga Basin Analysis for flood and Drought using CHyM model
First of all, I md saquib, my research area include, in this pre.
Md Saquib Saharwardi & Saadi Zulfaqar

2. The third largest river in the world by discharge!
Introduction
The third largest river in the world by discharge!
The Ganga basin outspreads in India, Tibet , Nepal and Bangladesh (10,86,000 Sq.km.)
26% of the total geographical area of India.
Length km
Average annual rainfall- 110 Cm

3. Objectives
To compare the drought and flood year using model parameters.
To analyze the performance of model for simulating Ganga basin.

4. Data
PERSIANN
ERA- Interim
RegCM

5. Static Fields

6. Slope and Velocity

7. Water Available for run-off (JJAS)
JUNE
JULY
AUGUST
SEPTEMBER

8. Water Available for run-off (JJAS)
MODEL
OBSERVATION

9. Total Water Content(JJAS)

10. Case Study 1988 – Flood 2002– Drought Flood Drought ±1000 death toll.
±9,000 affected villages and towns.
±100,000 evacuated.
Drought
Third largest drought in 100 years.
56% below normal rainfall = July.
Two-thirds districts = Poor rainfall.

11. Summer Monsoon Season (JJAS) Temperature
DROUGHT
FLOOD

12. Rain Input in JJAS Season
DROUGHT
FLOOD

14. Summary Model static fields performed well over Ganga Basin.
Model is able to differentiate between Observation (PERSIANN) and Model (RegCM) data for various parameters.
Model diffrentiated well drought and flood year.
