●● What is riverine flooding?
Answer: Flooding that occurs when a channel receives too much water,
causing excess flow over the banks into the adjacent floodplain.
●● What causes overbank flooding?
Answer: When a downstream channel receives more precipitation than
normal or is blocked by debris.
●● What is flash flooding?
Answer: A severe storm with heavy rainfall in a short time, often
occurring in hilly urban areas.
●● What is riverine erosion?
Answer: The transfer of sediment during flooding, affecting the shape of
channels over time.
●● What are coastal floods caused by?
,Answer: Coastal storms and hurricanes, with storm surges raising water
levels significantly.
●● What is a storm surge?
Answer: Water level rise caused by persistent high winds and changes in
air pressure during storms.
●● What is shallow flooding?
Answer: Flooding that occurs in flat areas lacking channels, where water
spreads out uniformly.
●● What is sheet flow?
Answer: Water spreading over a large area at a uniform depth due to
inadequate channels after intense rainfall.
●● What are closed basin lakes?
Answer: Lakes with no outlets or inadequate outlets, where seasonal
rainfall can cause rapid water level rises.
●● What is an alluvial fan?
Answer: A fan-shaped area where floodwaters decrease speed and
deposit sediment when moving from steep to flat slopes.
●● What are the hazards of dam breaks?
,Answer: High velocities and large volumes of water with little to no
warning, often due to structural failures.
●● What causes ice jams?
Answer: Warm weather and rain breaking up frozen rivers, leading to
blockages and sudden flooding downstream.
●● What are mudflows?
Answer: Landslides that occur when runoff saturates the ground, turning
dry soil into a liquid solution that slides downhill.
●● What are the natural functions of floodplains?
Answer: Floodwater storage, erosion control, water quality maintenance,
and groundwater recharge.
●● How does floodplain development impact flooding?
Answer: It alters the floodplain dynamics, leading to increased damage
from periodic flooding.
●● What are the main causes of flood damage?
Answer: Hydrodynamic forces, frontal impact, drag effect, and suction
from water movement.
●● What is the significance of the Community Rating System?
, Answer: It provides incentives for communities to engage in floodplain
management and reduce flood insurance premiums.
●● What role do natural barriers play in coastal areas?
Answer: They provide protection against flooding and erosion,
maintaining the stability of shorelines.
●● What is the impact of urban drainage systems?
Answer: They are designed to manage stormwater runoff but can lead to
flooding during larger storms.
●● What is the effect of vegetation on floodplains?
Answer: Vegetation stabilizes slopes, reduces erosion, and supports
biodiversity.
●● What is the purpose of flood insurance policies?
Answer: To provide financial protection against flood damage to
property and infrastructure.
●● What is the role of community participation in floodplain
management?
Answer: It enhances the effectiveness of floodplain management
strategies and fosters local awareness.
