Design a field survey any one of the following problems:

1. Environmental pollution

2. Soil degradation

3. Floods.

5. Land use and change direction

Floods.

Objectives : To identify and record areas experiencing reccuring flood conditions and to experience of floods as natural disaster.

Coverage:

Spatial: A field study conducted of a flood prone area of Brahmaputra Valley.

Temporal: The study is based on average condition reflecting responses of heavy rainfall. The problem pertains to flood. Thematically the assessment for agricultural production and crop land use rainfall and vegetation status should be made to understand.

Secondary Information : The maps and the data pertaining to the rainfall, crop production and population should be collected for flood affected areas.

Map: 1: 50000 and large scale topographical maps of the flood affected areas are needed.

Observation: Information about the heavy rainfall and damage of crops. Photographs and sketches of the area can give more information.

Measurement: The map shows the regions of the flood.

Interviewing: We interviewed some people of the affected area and collect the information related to flood, crops, livestock and domestic water supply, etc.
