Hydrological Cycle
soilmoisturestorage amount of water in the soil depends
on soil properties like soil texture and organic matter content
surface storage amount of water held on the Earth's
surface in lakes ponds and puddles
channel storage water stored in a river but flowing towards

Types of Hydrographs
Flashy stream that rise and fall quickly
subdued stream that doesn't rise as much and takes longer
Subdued Flashy Flashy Subdued
