The rainfall run off model HEC-HMS is combined with river routing model. They are used for simulating the rainfall process.
Explanation:
The HEC - HMS rainfall model is used for simulating the rainfall runoff process. In this study the soil conservation service and curve number method is used to calculate the sub basin loss in basin module.
It provides various options for providing the rainfall distributions in the basin. It has the control specification module used to control the time interval for the simulations.
The one dimensional continuity equation is
бA / бT + бQ / бx= 0
Answer:
D
Explanation:
I would say this awnser because its the only one that makes sence to me
The two ways you can use to make an informal survey are:
- make field observations
- interview people using informal unstructured techniques
<h3>What are informal surveys?</h3>
In informal surveys can be regarded as a type of survey that can be made by the researcher by going to the field themselves and this can be done by using different methods or ways.
For instance, the researcher can go out to interview people that can give the data that is needed about the research such as informally asking them questions, unstructured techniques can also be used to solve critical issues.

Answer:
![z_{2} = 91.640\,m](https://tex.z-dn.net/?f=z_%7B2%7D%20%3D%2091.640%5C%2Cm)
Explanation:
The phenomenon can be modelled after the Bernoulli's Principle, in which the sum of heads related to pressure and kinetic energy on ground level is equal to the head related to gravity.
![\frac{P_{1}}{\rho\cdot g} + \frac{v_{1}^{2}}{2\cdot g}= z_{2}+\frac{P_{2}}{\rho\cdot g}](https://tex.z-dn.net/?f=%5Cfrac%7BP_%7B1%7D%7D%7B%5Crho%5Ccdot%20g%7D%20%2B%20%5Cfrac%7Bv_%7B1%7D%5E%7B2%7D%7D%7B2%5Ccdot%20g%7D%3D%20z_%7B2%7D%2B%5Cfrac%7BP_%7B2%7D%7D%7B%5Crho%5Ccdot%20g%7D)
The velocity of water delivered by the fire hose is:
![v_{1} = \frac{(300\,\frac{gal}{min} )\cdot(\frac{3.785\times 10^{-3}\,m^{3}}{1\,gal} )\cdot(\frac{1\,min}{60\,s} )}{\frac{\pi}{4}\cdot (0.3\,m)^{2}}](https://tex.z-dn.net/?f=v_%7B1%7D%20%3D%20%5Cfrac%7B%28300%5C%2C%5Cfrac%7Bgal%7D%7Bmin%7D%20%29%5Ccdot%28%5Cfrac%7B3.785%5Ctimes%2010%5E%7B-3%7D%5C%2Cm%5E%7B3%7D%7D%7B1%5C%2Cgal%7D%20%29%5Ccdot%28%5Cfrac%7B1%5C%2Cmin%7D%7B60%5C%2Cs%7D%20%29%7D%7B%5Cfrac%7B%5Cpi%7D%7B4%7D%5Ccdot%20%280.3%5C%2Cm%29%5E%7B2%7D%7D)

The maximum height is cleared in the Bernoulli's equation:

Answer: To show his father what he had done
Explanation:
Percy Jackson is the son of the great Greek god of the seas, Poseidon. He did not however, know this for a long time. After he finds out, his life becomes more exciting as he embarks on many adventures.
