The "scientific hydrology" is concerned mainly with academic aspect, whereas, the "engineering" or "applied" hydrology includes: estimation of water resources; the study of processes like precipitation, evaporation, runoff and their interdependence; understanding the properties of water in nature; and ...
This post will review how multiple GSSHA scenarios can be added to hydrographs, a feature newly introduced in WMS 11.1.Hydrographs that show multiple GSSHA scenarios plot them all out within the same hydrograph. A legend below the graph will indicate which GSSHA scenario run is which in the ...

The most common method of calculating the amount of rainfall converted to runoff isthe SCS Curve Number (CN) Method, originally presented in the National Engineering Handbook, Section 4 (NEH-4). What is subsurface runoff? Subsurface runoffis the water that infiltrates in the vadose zone (unsatu...
Abstract: For design projects in water resources, a hydrograph is commonly used to determine the required flood volumes. The time base of a hydrograph isa crucial parameter in such studies, and its speedy and accurate determination is essential for both economic and hydrologic reasons. ...
The method was applied to a groundwater-pumping region in south-eastern Australia. The results showed that the model is able to separate the effects of pumping from the effects of climate on groundwater-head variation. However, improved estimation of those influences requires a flexible model ...
Unit Hydrograph Theory Moving water off of the watershed… A mathematical concept (based on linearity) Linear in nature Some History behind Unit Hydrograph Theory Sherman – 1932(first to propose the concept of ‘Unit Hydrograph’) Horton - 1933 Wisler & Brater - 1949 - “the hydrograph of sur...
Snyder’s Method - 4 2. UH Duration (tr): tr = tL / 5.5 where tr and tL are in [hrs]. If the duration of UH is other than tr, then the lag time needs to be adjusted as tpL = tL + 0.25 (tR - tr) where tLR = adjusted lag time; tR = desired UH duration. 3. UH Peak...
The hydrologic concepts of rainfall-runoff simulation used in Hydroggiss are presented. This includesthe description of various types of rainfall input, calculation of excess rainfall by the Soil Conservation Service (SCS) runoff curve number method (National Engineering Handbook*), and a proposed ...
