How can building up natural levees cause flooding worse downstream?
By building levees up you are able to "funnel" more water down stream to a point that has not been built up! This will cause more water to over flow the river banks creating a worse flood condition!

How can building on the drainage basin lead to flooding?
I assume you might be asking about the flood plain. The drainage basin is the very large area that feeds a river or stream. The flood plain is an area that is subject to flooding on a fairly normal basis. Building on the flood plain interrupts the natural pattern of flooding. The river will flood somewhere, the water has to go somewhere. if not on the natural flood plain perhaps in a city or town downstream.
How does urban development increase flooding?
Urban development can increase flooding by replacing natural areas like forests and wetlands with impermeable surfaces like concrete and asphalt. This prevents rainwater from being absorbed into the ground, leading to increased runoff and overwhelming drainage systems. Additionally, urban development can disrupt natural water flow patterns, exacerbating flooding in downstream areas.
Describe a beneficial effect that flooding can have on a flood plain?
Benefits of flooding may include increased soil moisture and higher crop yields. Also, allowing natural flooding may help reduce excessive sediment deposits downstream.
