How to Measure Rainfall / Precipitation
All the forms of precipitation are measure on the basis of vertical depth of water that would accumulate on a level surface of precipitation remained where it fell. In metric system precipitation is measure in millimeters and tenths. Any open receptacle with vertical side can be used as a gauges for measuring rainfall. These refined receptacles with vertical side can be
Estimation and Analysis of Missing Precipitation Data
Some precipitation stations may have short breaks in the records because of absence of the observer or because of instrumental failures. It is often necessary to estimate this missing record.Branches and Divisions of Hydrology
Hydrology can generally be divided into two main branches 1. Engineering Hydrology Engineering hydrology deals with the planning, design and Operation of Engineering projects for the control and use of water
Sub-Surface Movement of Groundwater
Water moves primarily downward due to gravity. Water infiltrates from surface and moves downward to water table or ponds on impermeable surface (clay layer, etc.) to form a Perched water tableGroundwater Occurrence and Types of Ground Water
Water is an essential requirements for all forms of the life and is considered as integral part of the living organisms life. GOD has gifted our universe with bulk amount of this valuable substance in different forms such asEstimating Missing Precipitation Data
Many precipitation stations have short breaks in their records because of absence of the observers or instrumental failure. It is must to estimate this missing record. The following method is adjusted for estimating this missing rainfall data.Important Flood Empirical Formulas
Hydrologic and hydraulic flood analysis are required for planning, design & management facilities. Analysis are needed to determine mar-flood elevation and depth, areas of inundation, sizing channels, levee height, design of highway crossing & culverts and many other.
