GENERAL GEOLOGY

Detailed explanation-1: -time interval from the start of rainfall to the peak discharge. Types of hydrographs include: Stream discharge hydrographs. Stream stage hydrographs.

Detailed explanation-2: -A storm hydrograph is a way of displaying how the discharge of a river can change over time in response to a rainfall event. The discharge of a river is just the amount of water passing a certain point every second, and is calculated by multiplying the cross sectional area of the river by its velocity.

Detailed explanation-3: -There are three main components to the hydrograph-rising limb, peak, and falling limb. The falling limb is often referred to as the recession curve, which provides information on the configuration of the karst conduits within an aquifer system, as well as its transmissivity and volume.

Detailed explanation-4: -As a UH is applicable only to the direct runoff component of a hydrograph (i.e., surface runoff), a separate determination of the baseflow component is required. A flood hydrograph is a graph of two axis, ‘discharge’ and ‘time’. Plotted on the graph is the amount of discharge over a period of time.

Detailed explanation-5: -Unit Hydrograph. Storm Hydrograph. Snyder’s Synthetic Unit Hydrograph. Annual Hydrograph. Monthly Hydrograph. Seasonal Hydrograph. Flood Hydrograph.
