Google Earth images (2.5 m spatial resolution) were used to extract catchment characteristics such as area, drainage lengths, number of houses in the catchment and the impervious surface area.
However, the severity of drought depends on the land types of particular region, their soil texture and moisture holding capacity, permeability, drainage and number of dry days etc. Apart from drought and flood, a few other constraints: salinity, alkaline and acid sulphate soils hamper rice cultivation and expansion in Bangladesh (Fig. 12d and Additional file 3: Figure S3).

Housing conditions was assessed by water plumbing supply (inside or outside the house), sewage (lack of sewage and pit sewage and general drainage), and number of people per room (1, 2 and 3 or more).
Secondary endpoints include complications such as pancreaticocutaneous fistula, exocrine or endocrine pancreatic insufficiency, need for additional radiological, endoscopic or surgical intervention, the need for necrosectomy after drainage, the number of (re- interventions, quality of life, and total dire- interventions costs.
A large meta-analysis review showed that subglottic drainage reduced the number of days of mechanical ventilation required and reduced the number of days stayed on the ICU [ 4].
It is connected to the Bay of Fundy by Minas Channel and receives the drainage of a number of rivers, including the Avon, Cornwallis, Salmon, and Shebenacadie.
This paper presents a novel optimization model for defining, in existing sewer drainage systems, the number of storage units, their location, size and the orifice dimensions.
In multivariate logistic regression analysis, larger AVM size, deep venous drainage, and increasing number of embolization or SRS sessions were negative predictors of complete obliteration.
Washed drainage gravel: the number of bags will depend on the size of your drain.
