In analyzing the graphs above, we could say that the height of rise of water in the river was faster that when the water subsided. A sudden rise of water in rivers occurs after a rainstorm. This is the time when there is accumulation of water in the river. Another incidence of a sudden rise of water in rivers is when there is a down pour of rain upstream. It may not fall on the exact location of the rise in water height, it could come from the accumulation of water somewhere in the upstream of the river.
In the study done in Cynon river, there was a steady flow of water on the first 42 hours. At the start of the 43rd hour, water began to rise. The rise of water in a hydrograph is called the rising limb. The water reached its peak flow at its52nd hour. The time of the peak flow is known to be the basin lag time. As the water starts to fall down, the term given to the falling down of the height of water is recession limb. After the falling down of water discharge, the water height starts to normalize. The storm flow is called the total of the overland flow, and the through flow. The overland flow, is the flow at which the water rises above the through flow and the through is termed as the water that rises above the base flow.
In the computations of the design of the open channel and the river, or the water source for a reservoir. or a water impounding area, there are factors or conditions to be taken into account. First, we must set conditions for the design criteria. Next, the elevation where the pump is to be placed or would it be feasible to have the pump in that certain location. If a pump is needed, how much force will the pump require in order to draw water from a river to a location higher that the river elevation.
Computations of the Channel design
With the given data below, it is required that we get the value of breadth b of an open channel using the Manning's Formula. After we achieve the value for the depth, it is also stated that we solve for the value of the width of the river where in, the river is the proposed water source of a nearby reservoir

Given Data
Q = 1.0 m3/s
n = 0.020
S = 1/3000 = 0.0003
d = 0.5
Formula to be used
V = where: v = velocity
Q = Av R = Hydraulic Radius
Q = A S = slope
A = bd n = Manning's coefficient

R = Q = discharge

Solutions to the required unknown
A = db
= 0.5(b)
Q = A
R =
1.0 = 0.5b
1.0(0.020) = 0.5b
0.0200 = 0.5b
= 0.5

Storm Drainage Design Project, Hydrographs
...April 28, 2009 Storm Drainage Design Project Introduction Hydrographs are used in the analysis of rivers. The line graph and the bar graph are usedto represent the activity of water flowing in rivers. Hence water from the river can be useful if we know how to make a design that is truly fruitful to end users. Usually, in the study of storm drainage, the analysis of hydrographs are considered. A hydrograph plots the river discharge and amount of rainfall as a function of time. In the study of storm drainage, the analysis of hydrographs are important. A hydrograph plots the river discharge...

...April 27,2009 Storm Drainage Design Project Introduction In the study of storm drainage design, we will be able to learn the functions of hydrographs in the design of open channels and reservoir. A hydrograph is a graph, either a bar graph or a line graph. A line graph is normally used to plot the discharge of water over the time, while a bar graph is the rise of water in the river over the function of time. There are factors that control the shapes of a hydrograph. According to Weyman, 1975 there are different shapes that are shown and the main components are labeled. The components of a hydrographs are...

Measurements are done at a certain point in a river. Rainfall is the input used to a watershed and the stream flow is also considered as the output of the watershed. A hydrograph also represents how a watershed reacts to rainfall. The response of a watershed to rainfall depends on several factors which affects the shape of a hydrograph. This represents the effect of rainfall on a particular basin. This is a hypothetical response of a watershed to...

Storm Drainage Design Project, Flood Hydrographs
...Storm Drainage Design Project 0 Introduction Flood hydrographs are very helpful to study the flood potential of a river. The flood hydrographs are constructed using the hydrological data consisting of rainfall distribution in the basin and the corresponding rise the river flow depth. When the discharge of the river versus the time is plotted a storm hydrograph is obtained (Geobytesgcse, n.d.). Various components of a hydrograph consist of a rising limb which represents the initial portion of a hydrograph, the peak discharge which related to the maximum discharge estimated and the receding limb , which relates to the decreasing part of the discharge with time. In addition hydrograph also carries information of base flow... , which is the...

...Storm Drainage Design Project Introduction Hydrology and hydraulic modeling systems are extensively used by infrastructure engineers and crisis management departments for estimation of availability of water, design of dams, diversions, and flood control through reservoirs or channels, etc. River statistics such as catchment area, river flow measurements, base flow and lag times is gathered through various sources such as satellite imagery and a network of stream gauges. Hydrograph analysis involves the study of runoff records at a stream gauge, river discharge after a rain and drainage rate of the river. Hydrograph analysis is also used...

Storm Drainage Design Project
...Storm Drainage Design Project 0 Introduction A storm hydrograph is the graphical representation of the response of the river discharge with respect to heavy rainfall. A detailed analysis of hydrographs would be of much help to estimate the flood potential of the region (Geobytesgcse, n.d.). The time repose of river to the rainfall is quantified as lag time which shows the time difference between the peak rainfall and the peak discharge in the river corresponding to that rainfall. Thus the rivers that have relatively short lag time respond very quickly to rainfall and hence can be considered as more prone to rainfall than those with larger lag time. The...

...flow is the quotient of the run-off volume (935,360 m3) and the duration of the receding limb (46 hours), which is equal to 20,333.91 m3/hour. The big difference between the rate of accumulation of flood water and the rate of recovery back to baseflow may be explained by the fact that 65% of the catchment area is of moderate permeability and does not lend itself to significant amount of infiltration. 3.0 Design of required pump power and open channel 3.1 Design consideration, assumptions and limitations: 3.1.1. Among the given values in the project assignment brief are: river width of 15 m; river cross section is rectangular; and river flow velocity of 4 m/s. 3.1.2. River water is...

...% of the Cynon River catchment area is of moderate permeability, suggesting slower infiltration rate and which should partly explain the substantial volume of overland flow and a steep rising limb (British Geological Society, 2005; Gordon, Finlayson, McMahon and Gippel, 2004). 3.0 Pumping and Channel Design Considering that a rainstorm with a height of 0.53 mm for 30 hours generated a theoretical run-off of 884,800 m3, it is very possible that water from the river may be utilized for storage in a reservoir. Following are the design considerations and assumptions: 1. It was assumed that pumping is required to discharge water from the river into an open channel which feeds the storage reservoir. 2. As...
