ASSIGNMENT Preliminary Estimations When preparing for water-related fieldwork or project development, it is often helpful to have advanced knowledge of site hydrology including weather, stream discharge, stage, topography, etc. This report contains hydrologic estimations for the basins given. The estimations include:

1.

Catchment area characteristics

From the map, Select a stream and a cross section. 1.1 Describe the physical features of a river and its valley from the map. 1.2 Define its catchment area, define the area. Comment the shape and the its characteristics. 1.3 Compute the time of concentration 2.
