A semi structured interview was designed to gather mostly qualitative data. The survey questions have been designed in consultation with local inhabitants and academics with options of flexibility and additions by the respondents. 35 households in Korail and 25 households in Mohammadpur beribadh area have been interviewed. 

The households have been chosen randomly based on the criteria of location, condition of houses, ownership and period of living in the area. For instance among the 30 households finally documented in Korail, 14 lived near the water edges, highly susceptible to flooding while other 16 live on higher ground in high density area with or without drainage facilities.

The housing condition varied between permanent to temporary character and the period of tenancy varied from less than 1 year to more than 5 years. The 25 households documented in Mohammadpur had variations in using building materials from stilt houses made entirely of bamboo to structures made as combination of brick, corrugated iron sheets and bamboo. Also the location varied from living on the embankment to inner side of the low-land. The survey included interviewing at least 2 household members (male/ female) preferable in two different times.

The answers of the respondents were compiled and analyzed from the filled out answer form using the programmes Microsoft Office Access, Excel and SPSS.
Notes, pictures and sketches provides important basis for the documentation.
