Hypsometric curve shows the percentage of the Earth’s surface above any elevation. The horizontal axis, labeled “% of Earth’s surface,” gives the percentage while the vertical axis shows elevation above or below sea level. Hypsometry vs Bathymetry : Hypsometry is The measurement of land elevation (MSL) while Bathymetry is the measurement of underwater elevation. How to […]

There are many types of Hydrograph based on the uses like Unit hydrograph Unit Hydrograph : The Unit Hydrograph (UH) is the simplest but at the same time a very powerful tool for hydrological analysis in general and flood forecasting. A unit hydrograph is a hydrograph of surface runoff that would result at a given

The hydrograph is a way of representing the water level over time. A hydrograph plot may display stage, streamflow, and sometimes both. Hydrographs can be a helpful way to show water level observations and forecasts visually on a single graphic.  The rate of flow is typically expressed in cubic meters per second. Hydrographs often relate changes

Flow net is a graphical representation of two-dimensional steady state ground water flow through aquifers. In a flow net, the strip between two adjacent flow lines is called a flow channel or flow tube. The drop in head between any two adjacent equipotential lines is the same and is called potential drop. Construction of a
Infiltration is the process by which water reaching the ground surface enters the soil. Infiltration rate is a measure at which soil is able to absorb rainfall. It is measured in mm per hour. Infiltration is governed by two forces Gravity and Capillary action. Smaller pores offer greater resistance to Gravity, very small pores pull
