Any books to learn the geo-sciense algorithm? about escape HOT 2 OPEN

A book that I would recommend is the one from Jon Pelletier -
Quantitative Modeling of Earth Surface Processes

Thanks a lot for recommending this book. I am reading it, and I would like to ask another two questions.
I see that gospl is another LEM project created by you. It looks similar with eSCAPE, but many things are different. What are their main differences, and their pros and cons?
Another thing I am confusing is that, the definition of priority-flood algorithm "edge" when simulating for earth. As a sphere, intuitively I think there should be no "edge", because in the scope of earth the water will not go to anywhere. However, when run gospl's bfModel, I see that 26 points are picked out from the overall 655362 points (gospl/flow/pitfilling.py Line 329); they seem relative with the elevation lowest points, but not exactly those ones. I do not understand the selecting process and its meaning here.
Thank you in advance.
