The precise and depictive accumulation of a stream flow data is vital in illustrating the water

The results shows us that the hypothesis between the river Loughton brook and the erosion shows that it gets wider and deeper due to many reasons such as vertical erosion, lateral erosion, hydraulic action and abrasion of rocks.

Next, it is necessary to identify the land that is possibly flooded and this can be calculated as:

To analyze the environmental monitoring policy and its resulting measurements in surface waters to determine the differentiation with respect to stream size and flow rate.

The watershed model is used to develop projections of peak stream flows and water surface (flood)

This project proposes that the stream banks be corrected from their current state of severe soil erosion. Some of the walls of soil surrounding the stream can reach approximately 1.8 meters in depth. Where the runoff drain meets the stream can even reach up to approximately 2.6 meters. The walls of the stream bank are a vault of in situ soils slowly restoring themselves to low sloping conditions through more erosion. This is an indicator that there has been extreme down cutting as result of stream channelization.

The typical upper course of a river is narrow in width, shallow in depth and slow in velocity. The load size is very large and therefore, less of it. The bank gradients are steep and the discharge levels are low. All these features gradually change as the river flows downstream. This is shown in figure 2

The mean for 100-year flood at ungauged river sites within the Apalachicola-ChattahoocheeFlint (ACF) River Basin is 8855.824, this value is importance in that it tells us the average of our data. The standard deviation is 5709.88 which gives us the summary the amount by which every value within a dataset varies from the mean. The max value of the data is 33300. As shown in the appendix figure 1 Illustrated Boxplot of the annual peak streamflow of with mean of 8856, the median of 6440, first quartile of 5260, third quartile of 10950, min of 2350 and max of 33300.The correlation coefficient between Peak and zp is 0.8895443 and the correlation coefficient between lnPeak and zp is 0.9829135.Figure 2 illustrated Histogram Plot of Annual Peak

The purpose of this report is to geologically evaluate the potential hazards for flooding in Hazard City. This report will include a detailed historic and extrapolated Stream Gauge Data Worksheet, as well as a graph of the Discharge Frequency Curve expected on Clearwater River. The report will provide Hazard city with my scientific analysis, conclusions, and provide recommendations concerning potential flood damages.

With Boise Idaho being one of the top 20 fastest growing cities in the US the water needs are going to be increasing over the next 20 + plus. Since 2012 the growth rate has been around a growth rate of 1.8. Boise has a pretty good location, It has the Boise river running through the middle of downtown boise. There are three dams that are located on the river just out side of town. Approximately 95% of Idahoans rely on ground water for drinking water. Surface water, such as streams, rivers, reservoirs, and springs, supplies the remaining 5%(DEQ). The first one is called Lucky Peak dam and the second one is called Arrow Rock dam and the third one is called Anderson Ranch dam. The Lucky Peak dam creates the Luck Peak lake. It has a capacity of 307,000 acre foot. Then the Arrow Rock dam created Arrow Rock reservoir and that has a holding capacity of 300,850 acre foot. Then Anderson Ranch dam has a carrying capacity of around 500,000 acre foot. So the three combine around to 1 million acre foot of water storage. Boise annually receives around 12 inches of rain per year. It gets around 8 or 9 inches of snow fall that turns into snow pack for this year. The snow pack just like the rain fall all just depends on the year. So we don 't get to much from rainfall and snowpack.

1. The water budget for a closed basin such as Mono lake can be generally described as: (rainfall + stream runoff + groundwater flow) - (evaporation + usage). Since it is difficult or impossible to accurately measure, groundwater flow can be expressed as equal to the difference between the actual measured storage of the lake and the calculated storage using: groundwater flow=actual measured storage - ((rainfall + stream runoff)-(evaporation + usage)).

Based on model tests, Civica will propose the modelling approach for Don River watershed. At the proposal stage, Civica would propose two approaches. The first approach is to create two models with different channel lengths. For small storms, the full length will be used. And for large storms, the length of valley corridor will be used. As the calibration and validation storms are usually small storms. The large storm model can’t be calibrated. It also increase the difficulty to manage different models. The second approach is to change the model algorithms to dynamically change to corresponding channel length based on water level. A threshold water level could be given to each channel element. If water level exceed the threshold water level,

Different types of cable or pipe will show differently on a radargram (Figure 5). Electrical cables are typically smaller than the gas or water pipes and can therefore be marginalised from other. Smaller cables have a series of less well pronounced cascading lines than the larger pipes. In some cases, particularly if they are directly below. In the event that the antenna passes over a point where the cable is in a near vertical position possibly before it passes underneath the river, it will appear as a series of cascading lines (figure

The water level (observed) and water level (simulated) water levels and the variation over time were graphed below in figure 5.

The relevance is given as we need an adequate material to build the dam as well as enough water to achieve a water level and finally to maintain that level. It also should be thought about a solution for the silt coming down the river in order to keep on getting a clear flush.

Advancement of technology has enabled us to manage and control the water resources in order to maximize the benefits gained through water. This is done by making dams, barrages and man-made streams. But this type of development also imbalances the different natural systems, eventually disturbing the sediment transport equilibrium which affects the system efficiency, reducing benefits derived from the dam construction. Bed aggradations on upstream of dams are seen as a result of such disturbance.
