Frequently Asked Questions
What is the hydrological cycle and why is it important for water resources?
The hydrological cycle describes water movement through evaporation, precipitation, infiltration, and runoff. Understanding it helps estimate available water resources, predict runoff patterns, and plan water resource development sustainably.
How are different precipitation analysis methods used?
Thiessen polygon method weights nearby raingauges by area; isohyetal method contours areas of equal rainfall. Choice depends on rainfall variation pattern and available raingauge network density for accurate areal precipitation.
What is the SCS-CN method and when is it used?
SCS-CN (Curve Number) method estimates runoff from rainfall considering land use, soil type, and initial soil moisture. It's widely used for ungauged catchments where runoff data is unavailable.
How is unit hydrograph used in flood prediction?
Unit hydrograph converts rainfall excess to streamflow for a catchment. It's used to develop design floods of specified return periods and predict peak discharge for different rainfall magnitudes and distributions.
What is reservoir sedimentation and how does it affect reservoir life?
Sedimentation is accumulation of suspended soil particles in reservoir. It reduces storage capacity over time, shortened reservoir life estimated using sediment yield and reservoir volume relationships.
How should I prepare for AI3404 exams?
Master precipitation analysis (Thiessen, isohyetal methods) and runoff calculation (Strange's table, SCS-CN); practice unit hydrograph problems; understand flood frequency analysis; study reservoir design and groundwater flow concepts.
