User reviews

PE

Needs to show formulas used in calculations. If not careful one could get poor results.

Not very user friendly

Needs a better interface. Formulas should be shown. Text gets cut off on menus. Please update. You can do much better. No sediment transport equations. Come on!!

A good tool..but

All sorts of great calculators ...but what's up with the long scrolling to find anything. Some menus would be nice. Also the words are too big and u can't see most of the description of what your clicking on!! But I give 3 stars cuz it's the only hydrology app! Please update this sucker...it was 5 bucks!!

Not quite ready for professional use.

great idea but needs more transparecy in formulas, more useful formulas, recommendations for obscure values (e.g. Vapor pressure), easier use of English units.

Needed additions

Not a bad start. How about adding a conversions calculator for hydraulic conductivity that includes cm/s, ft/d, gal/d/ft2, and other commonly used units, and the analogous units for transmissivity.
