A. FLOODS & EROSION CONTROL 

FLOOD SCENARIO 

• The topographical and the geographical location of North 

East Region is unique with the hydro-meteorological 

situation making it one of the highest rainfall zone in the 

World. 

• The main rivers causing floods in the North-east region are 

the Brahmaputra, Barak and their tributaries. 

• Flood - Main causes: 

– High Flows 

– Inundation 

– Drainage congestion 

– Bank erosion 

• Floods in Assam are caused mainly due to narrowness of 

the valley, high rainfall in the catchment, unstable steep 

slopes, long monsoon period etc

BROAD STRATEGY FOR FLOOD & 

EROSION MANAGEMENT 

• Absolute flood control and protection not feasible; 

reasonable degree of protection from flood losses 

at economic costs necessary 

• A combination of structural and non-structural 

measures in a phased manner is the most 

accepted strategy for flood management 

• A comprehensive approach towards management 

of flood 

6

Broad Functions of CWC in NE Region 

• Flood Forecasting and Warning system 

• Maintains Hydro Meteorological stations 

• Undertakes surveys and investigation 

• Monitoring of Irrigation projects 

• Techno economical appraisal of irrigation & flood 

management schemes 

• Technical Advice to N-E N E States & others 

regarding flood and erosion problems. 

7 

Flood Forecasting & Warning System 

Flood Forecasting(FF) & Warning System plays a 

significant role in reducing the loss of life and movable 

property during floods. CWC have a National Network of 

26 FF Stations in NE Region. 

Forecasts are formulated using 0800 hrs/ 0900 hrs 

water level data and issued at 1000 hrs with advance 

warning time ranging from 6 hrs to 36 hrs in NER during 

flood season.

2000. 

• It was decided to provide funds for critical flood 

control and anti-erosion works to states 

• Assistance also provided through Ministry of

Task Force For Flood 

Management/erosion Control 

• As per direction of Hon’ble Prime Minister, a Task 

Force under the Chairmanship of the Chairman,

FUNDING FOR CRITICAL FLOOD 

CONTROL & ANTI-EROSION WORKS 

• A scheme for Rs.150 crore for taking up 

critical flood control and anti erosion works 

under immidiate and short term measures in 

Brahmaputra & Barak Valley in the North 

Eastern States including Sikkim & North Bengal 

in State sector was approved in Dec., 2004. 

Revised EFC Memo amounting to Rs. 225 crore 

was approved by CCEA during 2006. 

• Execution is by concerned States and coordination 

by Brahmaputra Board. 

36

Hon’ble PM’s announcement 

• “The Government will consider establishing a 

cohesive, autonomous, self contained entity 

called the Brahmaputra Valley Authority or the 

North East Water Resources Authority to 

provide effective flood control, generate 

electricity, provide irrigation facilities & develop 

infrastructure. Given managerial and financial 

autonomy, equipped with top class manpower, 

and backed by Parliamentary sanction, such a 

body could be the instrument for transforming 

the region.” 

37 

Proposed 

North East Water Resources 

Authority (NEWRA) 

• MoWR prepared a proposal for North East 

Water Resources Authority (NEWRA) in line 

with TVA & DVC in consultation with States. 

• Government of Arunachal Pradesh expressed 

some reservation. 

38

Accelerated Irrigation Benefit 

Programme 

(AIBP) 

• In North Eastern (NE) States, most of the schemes 

are Minor Irrigation schemes. 

• The scope of AIBP has been extended to include 

Surface minor irrigation projects in special category 

states of NE, other hilly states and KBK districts of 

Orissa since 1999-2000. 

• Prior to December, 2006 the funding was in the ratio 

of 3:1 (Centre & State) and 90% of Centre’s share 

was given in the form of grant and 10 % as loan to be 

arranged by state with effect from 1.4.2004. 

• Fund provided as 90% grant & 10% State’s share 

since December, 2006.

GW scenario in NE region 

• Development of ground water in North Eastern Region is 

still in nascent stage. 

• There is ample scope for development but this region 

being hilly, only 30% of the existing area can be 

developed. (in the valley) 

• In the hilly area, the option available is to harvest rainwater 

through roof tops of buildings. 

• Harnessing ground water with proper planning and 

management coupled with roof-top rainwater harvesting, 

can uplift agro-economic scenario of the region.

Flood Forecast Performance 

– A level forecast is considered reasonably 

accurate if the difference between the forecast 

and the corresponding actual observed river 

level lies within +/- 15 cm. 

- On an average, 2000 level forecasts at various 

places in NE region are issued with 97.6% 

accuracy during the monsoon season every 

year. 

- In 2006, 1790 level forecasts were issued with an 

accuracy of 98.3%.
