Putting water in its place: a perspective on GIS in hydrology and water management

             This article represents how GIS is related with the hydra-logical process that allows for better managements and understanding. as well as introducing the term hydroGIS showing how closely related they are. The ability to see the valleys and flow using depth vectors and layers showed us what processes were happening over millions of years. We know what happens with a small stream over time but a river is on a scale all its own, never revealed until the use of GIS. Allowing us to see the water shed and tributaries on its full and grand scale and truly showing how interconnected and independent how rivers are. It highlighted the new theory that rivers create rather than occupy space, how there forces create and mold the world we see. Not only how the water gets from point a to point b but what other process happen in accordance with that. -- Lucas Evans

  1. I think that use of GIS to discover the land rivers have covered and how their courses have changed over the years is really interesting. I also like the idea of rivers creating space instead of occupying it. I think that has a connection to an environmentalists perspective of relating the earth to people. The river creating space makes it seem as if it was supposed to be there, which it was, and not as if it is intruding on the "humans land".

  2. GIS has many uses, and with the constant development of it, we can use it not only for occurrences relating to water but also what affects it and overtime how can we improve environmental issues. hydroGIS is just one of the many processes that GIS has brought to the table with it. In a few years, there is no doubt that GIS will provide more and more helpful tools to connect us to the environment is a positive manner.
