Diverging Overland Flow Application Natural Watersheds
font style='font-size:12px;'>
2009/10/28
The diverging overland flow model is utilized to predict surface runoff from
several natural watersheds. The Lax - Wendroff scheme is used to obtain
numerical solutions. This scheme is explicit, sin...

records were taken of the particle velocities ...
Diurnal Variations in Electrical Conductivity of Water in a Small Stream
Diurnal Variations Electrical Conductivity of Water Small Stream
font style='font-size:12px;'>
2009/10/28
Diurnal fluctuations in electrical conductivity of water have been observed in
a small streBm draining a basin 12 km2 in size. An attempt to explain the cause
of these variations is presented. The t...
