Burkli Ziegler Formula – To Determine the Peak Runoff Rate

Burkli Ziegler Formula Burkli Ziegler formula is the oldest formula used to determine the peak runoff rate. It was derived by a swiss engineer for local conditions. After that, it was followed in the whole U.S.A. In M.K.S unites it states that Where, ► = The peak runoff in cumecs. ► = Runoff coefficient (Depending … Continue reading Burkli Ziegler Formula – To Determine the Peak Runoff Rate

Find the Intensity of Rainfall When the duration of Rainfall is Given

Find the intensity of Rainfall When the duration of Rainfall is Given First of all, we need to know the formula used to determine rainfall intensity. There are three types of empirical formula, they are  a) For storm duration 5 to 20 minutes b) For storm duration 20 to 100 minutes c) Where rainfall is … Continue reading Find the Intensity of Rainfall When the duration of Rainfall is Given

How to Determine Runoff by using Rational Method – Mathematical Problem & Solution

How to Determine Runoff by using Rational Method First of all, we need to understand which formula or expression are used for determination of runoff. In rational method, the runoff is given by the following expression: Where, Q = Runoff in cumecK = Coefficient of runoffi = Intensity of rainfall in cm/hrA = Catchment area … Continue reading How to Determine Runoff by using Rational Method – Mathematical Problem & Solution

How to Determine Runoff Coefficient – Mathematical Problem & Solution

How to Determine Runoff Coefficient When the nature of the surface of different areas and the impermeability factors of the areas are known or given, then the value of runoff coefficient(K) may be determined by the following expression: Where,  a1, a2 = Area of different surfaces.p1, p2 = Impermeability factors of those surfaces.A = Total surface area. … Continue reading How to Determine Runoff Coefficient – Mathematical Problem & Solution

Spur

Spur

What is the Spur? Spur is a permeable and temporary structure. These structures are constructed on the curve of a river to protect the river bank from erosion. This type of structure is most suitable where the river carries sediment load in suspension. Don't be confused about spur and groynes, both are the same type … Continue reading Spur
