 +Can plagiarism detectors detect content from small websites ? Let's try:
 +====== Litt review ======
 +Estimating head may seem the easier task between the two mentioned before. Grossly,
 +the head of a chute is generally calculated using a DEM. There are actually two types of
 +models: simpler ones simply try to find the biggest head by finding the biggest terrain
 +slope[11], which can be done by scanning a DEM along the river course.
 +More advanced models can actually be a bit more clever: instead of having a
 +moderately down slope between two long distant points, it’s better to have no slope at all
 +for the majority of the distance and then a big slope at the end of it. That permits of
 +putting only a big dam, instead of many little ones. The disadvantage of this solution is
 +that the river’s bed is then modified, which creates environmental situations that may be
 +bad for the local ecosystem.
 +The actual problem that could arise with a model applied to the whole world is
 +that, as calculating the head needs a DEM, DEMs not always cover the whole world.
 +There are actually two main DEM that cover the majority of the world: Shuttle Radar
 +Topography Mission (SRTM) an Advanced Spaceborne Thermal Emission and Reflection
 +Radiometer (ASTER). ASTER is more precise and covers all the land, but the drawback
 +is that it is only possible to download ASTER in tiles, and this process is not automated.
 +====== proposition ======
 +Solar energy may be great, but it doesn’t produce during the night.
 +Hydro, on the other hand, produces at a more constant rate, but it is not
 +available everywhere (you have to find a good spot). As of 2015, Small
 +HydroPower (SHP) represented only 3% of the electricity generated in the
 +E.U.. But in France for example, there is still an unused hydroelectricity
 +energy potential (excluding protected rivers) of 3 TW
 +[4]. Multiple actors would want to install more SHP. For example, a small local cooperative
 +(like french electric cooperative Enercoop) could want to install a small
 +hydroelectric plant in their surroundings (in the same region for example) ;
 +but the problem is then to find which is the best spot (in economical and
 +technical terms) where to install the plant.
 +Moreover, less developed countries have a greater need for (cheaper and
 +cleaner) electricity. Some local communities don’t have the exact knowledge
 +where to install a plant (maybe it’s best for a small local community to build
 +the plant 5 km away if the plant can produce significantly more there).
 +This spot finding process could be done manually, either by surveying
 +the local rivers or by using GIS tools, like [2]. Our goal is to be able to build a
 +model which could calculate itself (using some input data) the spots along the
 +river where the construction of an SHP plant would have the most economic
 +sense. Also, as many people are not tech-minded,​ the model must be shown
 +in a simple and understandable way. As the web is omnipresent nowadays,
 +we will choose the show this model as a web application usable by everybody.
