effect of deforestation on the amont of surface runoff

-

The removal of trees reduces the amunt of water intercepted,and hence the amount evaporated back into the atmosphere and more water reches the ground more quickly.the effect of trees on runof depends on the area of forest cleared,type of forest and the climate.Differences in climate make it difficult to compare the effects of removal of trees of different types of forests on runoff.

More the frequency of rainfall,longer will be the saturation of the canopy effect on runoff from a wet catchment (eg., in upland Wales) than in the dry catchment (eg., in southern England), the greater the amount of mechanical intervention and the more brutal the method used for deforestation the greater will be the runoff .Removing coniferous forest has the greatest absolute effect on surface runoff but percentage increase may.

How does slope influence runoff

-
Runoff is the precipitation excess or the water leaving a drainage area regarded as rainfall minus loss by evaporation or infiltration.Runoff volume is the total volume of runoff water occuring over a period of time where Q(t) is the discharge at time t and the expression is :- Total runoff is the sum of the overland flow,ground water flow and through flow.The reason why water flow down hill over a sloping land surface is because of the following of the Bernoulli's equation .However,other opinion says the reason is decrease in potential energy rather than Bernoulli's equation .Steep slope will provoke speedy movement of water towards the outlet while gentle slope will result in slow movement allowing evapotranspiration.If the soil is porous then there will be infiltration and downflow in the form of throughflow or it may enter the ground water flow.Surface runoff or infiltration excess overland flow can only occur on the catchment slope if :- a)Rainfall rate is gre...

How using a dishwasher brought relief to my family and how I use it?

-
 Making the choice I came across several youtube videos on dishwasher initially. I am a tech savvy person and love to automate repeatative tasks and I have a goal to automate most of my household repeatative tasks. So, that we get quality time together and are not dependent on domestic help for heavy lifting. We have children and not a large family where she would receive support in child daily activities from family seniors. As a result, we are very much on our own and have to depend on our own time management and on machines - washing machine, refrigerator, 2 wheelers, amazon scheduled deliveries, dishwasher for our comfort and daily work needs. Deciding on the machine I checked different dishwasher online and zeroed in on Voltas beko 8 place set. It is the smallest and the cheapest machine with the highest review in the online e-commerce space.I also did a market study to see if the dishwasher specific detergents are available offline. It is not available. I also went to a local...

Airtel DTH: Error B001/Error B003 and Why I left Airtel possibly for Better

Why did I decided to Leave?  It has been 2 weeks since I complained about B001 error and Airtel in between replaced 2 set top boxes but problem remained. I have replaced everything as per "diagnosis" of airtel DTH technician but no solution could be reached. Currently, my balance has been deducted from INR200 to INR 10. There are discrepancies with the bills issued against parts replacements conducted during this period. It must be stressed here that I as a customer felt cheated, neglected, harassed by Airtel +Service Partner and I was a 7-8 years+ customer. We never saw that set top box seals were broken in front of our eyes for both the replacements by technicians. My comparison chart for new service provider
