Neco Model Questions Vol1 2024 Geography Question 26
Practice objective / multiple choice question 26 from the 2024 Neco Model Questions Vol1 Geography examination.
A catchment area of \(250\ \text{km}^2\) originally has a total stream length of \(180\ \text{km}\). A newly discovered tributary adds an unknown length \(L\) km, increasing the total length to \(200\ \text{km}\). Subsequently, urban development channelises \(15\%\) of the original streams (the original \(180\ \text{km}\) only). Determine the drainage density (total effective stream length per unit area) after these changes, expressed in km\,km\(^{-2}\) to two decimal places.
